SP building undersea transmission cable tunnel It will connect Jurong Island to the mainland By RONNIE LIM ronnie@sph.com.sg ONE year after starting construction of Singapore’s $2 billion next-generation power network, Singapore Power (SP) is now following up by building a crucial new undersea transmission cable tunnel connecting Jurong Island (JI) to the mainland to export electricity from new power plants there. Penta-Ocean Construction, which was awarded the latest contract in October, started work last month on the 5.2 km JI-Pioneer (Road) cable tunnel under the West Jurong Channel, Singapore Power disclosed in its just-released 2012/13 annual report. No project cost was mentioned because of contractual reasons. “Cost-wise, it is a fraction of the $2 billion mainland tunnel project. But the undersea tunnel is not a small project, and it is also more challenging as it goes deeper,” said SP’s CEO, Wong Kim Yin, in an interview. Expected to be around 45 metres to 80 metres deep, the undersea cable tunnel is “planned in conjunction with the (next-generation) 400kV West Jurong Island substation and will accommodate up to 10 circuits” from JI to the mainland, SP added. It will also house Singapore’s next-generation 400 kV transmission cables (replacing current 230kV ones) which have greater capacity to handle the volume of electricity being generated and transmitted here. SP had earlier carried out both preliminary and detailed soil investigations, as the tunnel will be built through Jurong sedimentary formation. The undersea cable tunnel is scheduled for completion by 2018, in time to handle the substantial increase in transmission load from JI, which is seeing new plantings by gencos including Keppel Merlimau Cogen, Sembcorp Cogen, Tuas Power’s multi-utilities complex and newcomer PacificLight Power. “By 2019, transmission load in south-western Singapore is expected to increase by 62.5 per cent,” SP said, explaining the need to expand the transmission cable network in that area, which includes Jurong Island and Tuas (where the new port will also be built). Timing-wise, it will also tie in with the expected completion of the mega $2 billion cross-island tunnel The undersea cable tunnel is scheduled for completion by 2018, in time to handle the substantial increase in transmission load from JI, which is seeing new plantings. project on the mainland. Comprising two ultra-deep, extra-high voltage power transmission tunnels running 16.5 km east-west and 18.5 km north-south, the tunnels are expected to be completed in Q2, 2017 and Q2, 2018 respectively. Tunnelling proper of the two is set to start early next year, following the completion of the upper and lower access shafts this year. In its annual report, SP said that it is leveraging cutting-edge technology and investing in network infrastructure to support key industries and economic and social developments. For instance, it said that to cater for future growth and development of petrochemical industries on JI, development of Tembusu 230kV and 400kV West Jurong Island substations is progressing. Rangoon 400kV substation is also set to be completed by this year-end to cater to power demand growth in central Singapore. On the gas front, subsidiary PowerGas also supported the start-up of the Singapore LNG terminal in May this year by laying pipelines connecting SLNG to new transmission customers.

A6 TOPOF THENEWS | THE STRAITS TIMES | WEDNESDAY, DECEMBER 20, 2017 | Singapore’s deepest tunnel system The Underground Transmission Cable Tunnel Project will safeguard Singapore’s electricity supply network for the future. It will begin operations by the end of next year. ST illustrates the key points of this $2.4 billion engineering feat.

Robots, or automatic inspection vehicles (AIVs), traversing the length of the 40km tunnels, will look out for changes in the colour of the concrete walls, a warning sign for water leaks. Mr Michael Chin, managing director of infrastructure and projects at energy utility company SP Group, said yesterday that water leaks are the most common problem in tunnels, and AIVs can detect concrete patches that suddenly turn a different colour. He said the AIVs will also eventually be able to detect fires using infrared cameras. Each of the three tunnels also has a firefighting system that uses a superior “water mist system”, instead of sprinklers, said Mr Chin. He explained that the system shoots very fine water mist which evaporates faster and removes heat quickly from fire. The water mist also displaces air and suffocates the flames. Smoke particles will dissolve into the fine water droplets and sink, leaving a fine mist and making it safe for firefighters to enter the tunnel to put out the fire, said Mr Chin. The system also sends an alarm signal to the Singapore Civil Defence Force. Another set of sensors in the tunnels can detect pollutants and abnormal concentrations of gases. Most parts of the multibillion-dollar Underground Transmission Cable Tunnel Project are about 60m beneath the earth, but some will be at 80m, making the electricity project one of the world’s deepest. The tunnels – named the North-South, East-West and Jurong Island-Pioneer tunnels – will be able to house 1,200km of extra-high-voltage cables. Singaporeans will begin tapping this source from next year, said SP Group yesterday. About 500km of cables will be laid, which is less than half the capacity of the tunnels. There will be 17 equipment buildings spanning the 40km network, and each of them will have two electric bicycles to allow staff to quickly move to parts of the tunnels that require attention. Mr Chin said that anyone trying to enter the tunnels will need to break through three layers of security at the equipment buildings. “All these systems protect the cables and the people working in the tunnel and so, in the long run, maintain the reliability of the system,” he said. josehong@sph.com.sg SCAN TO WATCH A walk through the underground tunnels. http://str.sg/ tunnels West Jurong Island 400kV substation Ayer Rajah 400kV substation Rangoon 400kV substation FACTS AND FIGURES 3 21 tunnels shafts long 60-80m deep 40km tunnel High-tech protection There are only 17 entry points to the tunnel, and each of them has three levels of security and surveillance cameras.

These cables were installed just below roads, and repairs and replacement work would cause traffic jams and increase the risk of accidents – problems that the new underground tunnel network will avoid, said SP Group managing director of infrastructure and projects Michael Chin. He added that the existing cables are so old that they need to be inspected once every three months, which adds to maintenance costs. Singapore’s land scarcity means that SP Group had “no choice” but to build the tunnel system 60m below ground, said Mr Chin. He said that the 60m-deep tunnels mean that cable checks will not disrupt ground-level life. Reflecting long-term planning, Mr Chin said the 40km tunnel project is designed to last 120 years. This refers to the concrete segments and the structural reinforcements. However, he said that there is no knowing what will happen once the system ends. “I will not be around and you will not be around,” he chuckled, adding that Singapore could end up with a completely different system of transmitting electricity.

Robots, or automatic inspection vehicles (AIVs), traversing the length of the 40km tunnels, will look out for changes in the colour of the concrete walls, a warning sign for water leaks. Mr Michael Chin, managing director of infrastructure and projects at energy utility company SP Group, said yesterday that water leaks are the most common problem in tunnels, and AIVs can detect concrete patches that suddenly turn a different colour. He said the AIVs will also eventually be able to detect fires using infrared cameras. Each of the three tunnels also has a firefighting system that uses a superior “water mist system”, instead of sprinklers, said Mr Chin. He explained that the system shoots very fine water mist which evaporates faster and removes heat quickly from fire. The water mist also displaces air and suffocates the flames. Smoke particles will dissolve into the fine water droplets and sink, leaving a fine mist and making it safe for firefighters to enter the tunnel to put out the fire, said Mr Chin. The system also sends an alarm signal to the Singapore Civil Defence Force. Another set of sensors in the tunnels can detect pollutants and abnormal concentrations of gases. Most parts of the multibillion-dollar Underground Transmission Cable Tunnel Project are about 60m beneath the earth, but some will be at 80m, making the electricity project one of the world’s deepest. The tunnels – named the North-South, East-West and Jurong Island-Pioneer tunnels – will be able to house 1,200km of extra-high-voltage cables. Singaporeans will begin tapping this source from next year, said SP Group yesterday. About 500km of cables will be laid, which is less than half the capacity of the tunnels. There will be 17 equipment buildings spanning the 40km network, and each of them will have two electric bicycles to allow staff to quickly move to parts of the tunnels that require attention. Mr Chin said that anyone trying to enter the tunnels will need to break through three layers of security at the equipment buildings. “All these systems protect the cables and the people working in the tunnel and so, in the long run, maintain the reliability of the system,” he said. josehong@sph.com.sg SCAN TO WATCH A walk through the underground tunnels. http://str.sg/ tunnels West Jurong Island 400kV substation Ayer Rajah 400kV substation Rangoon 400kV substation FACTS AND FIGURES 3 21 tunnels shafts long 60-80m deep 40km tunnel High-tech protection There are only 17 entry points to the tunnel, and each of them has three levels of security and surveillance cameras.

These cables were installed just below roads, and repairs and replacement work would cause traffic jams and increase the risk of accidents – problems that the new underground tunnel network will avoid, said SP Group managing director of infrastructure and projects Michael Chin. He added that the existing cables are so old that they need to be inspected once every three months, which adds to maintenance costs. Singapore’s land scarcity means that SP Group had “no choice” but to build the tunnel system 60m below ground, said Mr Chin. He said that the 60m-deep tunnels mean that cable checks will not disrupt ground-level life. Reflecting long-term planning, Mr Chin said the 40km tunnel project is designed to last 120 years. This refers to the concrete segments and the structural reinforcements. However, he said that there is no knowing what will happen once the system ends. “I will not be around and you will not be around,” he chuckled, adding that Singapore could end up with a completely different system of transmitting electricity.

Penta-Ocean Construction, which was awarded the latest contract in October, started work last month on the 5.2 km JI-Pioneer (Road) cable tunnel under the West Jurong Channel, Singapore Power disclosed in its just-released 2012/13 annual report. No project cost was mentioned because of contractual reasons. “Cost-wise, it is a fraction of the $2 billion mainland tunnel project. But the undersea tunnel is not a small project, and it is also more challenging as it goes deeper,” said SP’s CEO, Wong Kim Yin, in an interview. Expected to be around 45 metres to 80 metres deep, the undersea cable tunnel is “planned in conjunction with the (next-generation) 400kV West Jurong Island substation and will accommodate up to 10 circuits” from JI to the mainland, SP added. It will also house Singapore’s next-generation 400 kV transmission cables (replacing current 230kV ones) which have greater capacity to handle the volume of electricity being generated and transmitted here. SP had earlier carried out both preliminary and detailed soil investigations, as the tunnel will be built through Jurong sedimentary formation. The undersea cable tunnel is scheduled for completion by 2018, in time to handle the substantial increase in transmission load from JI, which is seeing new plantings by gencos including Keppel Merlimau Cogen, Sembcorp Cogen, Tuas Power’s multi-utilities complex and newcomer PacificLight Power. “By 2019, transmission load in south-western Singapore is expected to increase by 62.5 per cent,” SP said, explaining the need to expand the transmission cable network in that area, which includes Jurong Island and Tuas (where the new port will also be built). Timing-wise, it will also tie in with the expected completion of the mega $2 billion cross-island tunnel The undersea cable tunnel is scheduled for completion by 2018, in time to handle the substantial increase in transmission load from JI, which is seeing new plantings. project on the mainland. Comprising two ultra-deep, extra-high voltage power transmission tunnels running 16.5 km east-west and 18.5 km north-south, the tunnels are expected to be completed in Q2, 2017 and Q2, 2018 respectively. Tunnelling proper of the two is set to start early next year, following the completion of the upper and lower access shafts this year. In its annual report, SP said that it is leveraging cutting-edge technology and investing in network infrastructure to support key industries and economic and social developments. For instance, it said that to cater for future growth and development of petrochemical industries on JI, development of Tembusu 230kV and 400kV West Jurong Island substations is progressing. Rangoon 400kV substation is also set to be completed by this year-end to cater to power demand growth in central Singapore.

Most parts of the multibillion-dollar Underground Transmission Cable Tunnel Project are about 60m beneath the earth, but some will be at 80m, making the electricity project one of the world’s deepest. The tunnels – named the North-South, East-West and Jurong Island-Pioneer tunnels – will be able to house 1,200km of extra-high-voltage cables. Singaporeans will begin tapping this source from next year, said SP Group yesterday. About 500km of cables will be laid, which is less than half the capacity of the tunnels. There will be 17 equipment buildings spanning the 40km network, and each of them will have two electric bicycles to allow staff to quickly move to parts of the tunnels that require attention. Mr Chin said that anyone trying to enter the tunnels will need to break through three layers of security at the equipment buildings. “All these systems protect the cables and the people working in the tunnel and so, in the long run, maintain the reliability of the system,” he said. josehong@sph.com.sg SCAN TO WATCH A walk through the underground tunnels. http://str.sg/ tunnels West Jurong Island 400kV substation Ayer Rajah 400kV substation Rangoon 400kV substation FACTS AND FIGURES 3 21 tunnels shafts long 60-80m deep 40km tunnel High-tech protection There are only 17 entry points to the tunnel, and each of them has three levels of security and surveillance cameras.

Penta-Ocean Construction, which was awarded the latest contract in October, started work last month on the 5.2 km JI-Pioneer (Road) cable tunnel under the West Jurong Channel, Singapore Power disclosed in its just-released 2012/13 annual report. No project cost was mentioned because of contractual reasons. “Cost-wise, it is a fraction of the $2 billion mainland tunnel project. But the undersea tunnel is not a small project, and it is also more challenging as it goes deeper,” said SP’s CEO, Wong Kim Yin, in an interview. Expected to be around 45 metres to 80 metres deep, the undersea cable tunnel is “planned in conjunction with the (next-generation) 400kV West Jurong Island substation and will accommodate up to 10 circuits” from JI to the mainland, SP added. It will also house Singapore’s next-generation 400 kV transmission cables (replacing current 230kV ones) which have greater capacity to handle the volume of electricity being generated and transmitted here. SP had earlier carried out both preliminary and detailed soil investigations, as the tunnel will be built through Jurong sedimentary formation. The undersea cable tunnel is scheduled for completion by 2018, in time to handle the substantial increase in transmission load from JI, which is seeing new plantings by gencos including Keppel Merlimau Cogen, Sembcorp Cogen, Tuas Power’s multi-utilities complex and newcomer PacificLight Power. “By 2019, transmission load in south-western Singapore is expected to increase by 62.5 per cent,” SP said, explaining the need to expand the transmission cable network in that area, which includes Jurong Island and Tuas (where the new port will also be built).

Comprising two ultra-deep, extra-high voltage power transmission tunnels running 16.5 km east-west and 18.5 km north-south, the tunnels are expected to be completed in Q2, 2017 and Q2, 2018 respectively. Tunnelling proper of the two is set to start early next year, following the completion of the upper and lower access shafts this year. In its annual report, SP said that it is leveraging cutting-edge technology and investing in network infrastructure to support key industries and economic and social developments. For instance, it said that to cater for future growth and development of petrochemical industries on JI, development of Tembusu 230kV and 400kV West Jurong Island substations is progressing. Rangoon 400kV substation is also set to be completed by this year-end to cater to power demand growth in central Singapore.

Robots, or automatic inspection vehicles (AIVs), traversing the length of the 40km tunnels, will look out for changes in the colour of the concrete walls, a warning sign for water leaks. Mr Michael Chin, managing director of infrastructure and projects at energy utility company SP Group, said yesterday that water leaks are the most common problem in tunnels, and AIVs can detect concrete patches that suddenly turn a different colour. He said the AIVs will also eventually be able to detect fires using infrared cameras. Each of the three tunnels also has a firefighting system that uses a superior “water mist system”, instead of sprinklers, said Mr Chin. He explained that the system shoots very fine water mist which evaporates faster and removes heat quickly from fire. The water mist also displaces air and suffocates the flames.

Robots, or automatic inspection vehicles (AIVs), traversing the length of the 40km tunnels, will look out for changes in the colour of the concrete walls, a warning sign for water leaks. Mr Michael Chin, managing director of infrastructure and projects at energy utility company SP Group, said yesterday that water leaks are the most common problem in tunnels, and AIVs can detect concrete patches that suddenly turn a different colour. He said the AIVs will also eventually be able to detect fires using infrared cameras. Each of the three tunnels also has a firefighting system that uses a superior “water mist system”, instead of sprinklers, said Mr Chin. He explained that the system shoots very fine water mist which evaporates faster and removes heat quickly from fire. The water mist also displaces air and suffocates the flames. Smoke particles will dissolve into the fine water droplets and sink, leaving a fine mist and making it safe for firefighters to enter the tunnel to put out the fire, said Mr Chin. The system also sends an alarm signal to the Singapore Civil Defence Force. Another set of sensors in the tunnels can detect pollutants and abnormal concentrations of gases. Most parts of the multibillion-dollar Underground Transmission Cable Tunnel Project are about 60m beneath the earth, but some will be at 80m, making the electricity project one of the world’s deepest. The tunnels – named the North-South, East-West and Jurong Island-Pioneer tunnels – will be able to house 1,200km of extra-high-voltage cables. Singaporeans will begin tapping this source from next year, said SP Group yesterday. About 500km of cables will be laid, which is less than half the capacity of the tunnels. There will be 17 equipment buildings spanning the 40km network, and each of them will have two electric bicycles to allow staff to quickly move to parts of the tunnels that require attention. Mr Chin said that anyone trying to enter the tunnels will need to break through three layers of security at the equipment buildings. “All these systems protect the cables and the people working in the tunnel and so, in the long run, maintain the reliability of the system,” he said. josehong@sph.com.sg SCAN TO WATCH A walk through the underground tunnels. http://str.sg/ tunnels West Jurong Island 400kV substation Ayer Rajah 400kV substation Rangoon 400kV substation FACTS AND FIGURES 3 21 tunnels shafts long 60-80m deep 40km tunnel High-tech protection There are only 17 entry points to the tunnel, and each of them has three levels of security and surveillance cameras.

These cables were installed just below roads, and repairs and replacement work would cause traffic jams and increase the risk of accidents – problems that the new underground tunnel network will avoid, said SP Group managing director of infrastructure and projects Michael Chin. He added that the existing cables are so old that they need to be inspected once every three months, which adds to maintenance costs. Singapore’s land scarcity means that SP Group had “no choice” but to build the tunnel system 60m below ground, said Mr Chin. He said that the 60m-deep tunnels mean that cable checks will not disrupt ground-level life. Reflecting long-term planning, Mr Chin said the 40km tunnel project is designed to last 120 years. This refers to the concrete segments and the structural reinforcements. However, he said that there is no knowing what will happen once the system ends. “I will not be around and you will not be around,” he chuckled, adding that Singapore could end up with a completely different system of transmitting electricity.

Penta-Ocean Construction, which was awarded the latest contract in October, started work last month on the 5.2 km JI-Pioneer (Road) cable tunnel under the West Jurong Channel, Singapore Power disclosed in its just-released 2012/13 annual report. No project cost was mentioned because of contractual reasons. “Cost-wise, it is a fraction of the $2 billion mainland tunnel project. But the undersea tunnel is not a small project, and it is also more challenging as it goes deeper,” said SP’s CEO, Wong Kim Yin, in an interview. Expected to be around 45 metres to 80 metres deep, the undersea cable tunnel is “planned in conjunction with the (next-generation) 400kV West Jurong Island substation and will accommodate up to 10 circuits” from JI to the mainland, SP added. It will also house Singapore’s next-generation 400 kV transmission cables (replacing current 230kV ones) which have greater capacity to handle the volume of electricity being generated and transmitted here. SP had earlier carried out both preliminary and detailed soil investigations, as the tunnel will be built through Jurong sedimentary formation. The undersea cable tunnel is scheduled for completion by 2018, in time to handle the substantial increase in transmission load from JI, which is seeing new plantings by gencos including Keppel Merlimau Cogen, Sembcorp Cogen, Tuas Power’s multi-utilities complex and newcomer PacificLight Power. “By 2019, transmission load in south-western Singapore is expected to increase by 62.5 per cent,” SP said, explaining the need to expand the transmission cable network in that area, which includes Jurong Island and Tuas (where the new port will also be built). Timing-wise, it will also tie in with the expected completion of the mega $2 billion cross-island tunnel The undersea cable tunnel is scheduled for completion by 2018, in time to handle the substantial increase in transmission load from JI, which is seeing new plantings. project on the mainland. Comprising two ultra-deep, extra-high voltage power transmission tunnels running 16.5 km east-west and 18.5 km north-south, the tunnels are expected to be completed in Q2, 2017 and Q2, 2018 respectively. Tunnelling proper of the two is set to start early next year, following the completion of the upper and lower access shafts this year. In its annual report, SP said that it is leveraging cutting-edge technology and investing in network infrastructure to support key industries and economic and social developments. For instance, it said that to cater for future growth and development of petrochemical industries on JI, development of Tembusu 230kV and 400kV West Jurong Island substations is progressing. Rangoon 400kV substation is also set to be completed by this year-end to cater to power demand growth in central Singapore. On the gas front, subsidiary PowerGas also supported the start-up of the Singapore LNG terminal in May this year by laying pipelines connecting SLNG to new transmission customers.

SP Energy HubAnnual ReportReliabilitySustainabilityInnovation Planning for Singapore’s Long-Term Network Reliability RELIABILITY When completed by 2019, the underground transmission cable tunnel project will play an integral part of SP Group’s long-term plan to secure reliable and efficient electricity supply for Singapore. It will enable SP to plan and anticipate future network requirements. It will also allow us to install, repair and replace aging assets, and upgrade our network efficiently, with minimal inconvenience to the public. Constructions on this project started in 2012. Comprising three underground tunnels spanning 40km around Singapore, the tunnels were constructed at a depth of 60 meters below ground (the “height” of a 20-storey building) to minimise the congestion of underground utility services. These are the deepest tunnels to be ever constructed in Singapore, and will house 1,200km of extra-high voltage cables. The tunnels consist of: The North-South Tunnel – 18.5km tunnel from Gambas to May Road The East-West Tunnel – 16.5km tunnel from Ayer Rajah to Paya Lebar The Jurong Island-Pioneer Tunnels – 5km tunnel from Benoi to Jurong Island Built to last 120 years, the tunnels will allow Singapore to be equipped with optimal electricity supply infrastructure for the future and ensure that the nation will continue to have one of the best performing electricity networks in the world. — 26 June 2018 Watch this video to find out more about the transmission cable tunnel project.

23 July 2014 News Release Singapore Power boosts public safety around major construction sites with two new roads for heavy vehicles Access roads at May Road and Kallang bypass schools and residential areas Singapore Power (SP) has stepped up public safety measures by building two roads for heavy construction vehicles to access its May Road and Kallang cable tunnel sites directly from expressways, bypassing nearby residential areas and schools. The move has been well received by community stakeholders, whom Singapore Power consulted in the course of undertaking this initiative. At the May Road site, SP constructed an additional lane to the Central Expressway (CTE) in the city-bound direction before the Balestier Road exit. This allows heavy vehicles to enter and exit the site without taking the narrow roads around Hong Wen School and the residential neighbourhood around McNair Road, Towner Road and May Road. At the Kallang site, an access way was created off the slip road alongside the Pan-Island Expressway (PIE), in the direction of Bendemeer at Geylang Bahru. Construction vehicles now do not drive through Geylang Bahru and Geylang Bahru Lane, as well as around Kallang Basin Swimming Complex, to enter or exit the Kallang site. The roads were built in the first half of 2014 at a total cost of about $4 million, with the one at Kallang opening first in January and the one at May Road opening in May. “At Singapore Power, we spare no effort in ensuring the safety of the community, our workers and contractors,” said Michael Chin, Managing Director (Special Projects), SP PowerGrid. “This initiative meant going beyond established industry practices for safety. We will continue to be alert to any risks and room for improvement at our sites.” The new access roads are the latest of safety measures implemented from the onset of the cable tunnel construction in end 2012. Initial safety measures included deploying traffic marshals at schools, restricting heavy vehicle traffic during school peak hours, giving talks to students to raise road safety awareness and installing water barricades to prevent jaywalking around the construction sites. SP formulated these safety measures in consultation with community stakeholders. The project teams make door-to-door visits to residents and attend monthly Residents’ Committee meetings. For the May Road site, these stakeholders included Hong Wen School, Whampoa McNair and St George’s West Residents’ Committees, Whampoa Citizens’ Consultative Committee and residents living near the site. At the Kallang site, there is regular consultation 1 with the Kallang Bahru Residents’ Committee, Kolam Ayer Citizens’ Consultative Committee, Kallang Basin Swimming Complex, Saint Joseph’s Institution Junior (when the holding school was there) and residents living near the site. “Safety is of paramount importance to us. We appreciate the continuous engagement efforts by Singapore Power, as well as the many proactive measures which it has introduced to help ensure the safety of road users in our community,” said Mr Raymond Poon, principal of Hong Wen School. “The safety of our residents and children is of the highest importance to us, so it is heartening to see the road safety measures that Singapore Power has implemented and especially the creation of this new access into the Kallang construction site,” said Chiang Heng Liang, Chairman of the Kolam Ayer Citizens’ Consultative Committee. “Prevention is better than cure, so it is prudent to segregate heavy vehicle traffic from the residential road network when and where feasible.” All heavy vehicles entering or exiting the May Road site will use the new access road, only outside of peak hours, to ensure minimal impact on CTE traffic. The existing safety measures along May Road will remain in force as light vehicles continue to use the previous site access. All vehicles entering or exiting the Kallang site will use the new access road instead of Geylang Bahru Lane.

Two cross-island, ultra-deep tunnels, each to house extra-high voltage power transmission cables, are to be built. Work on them will start in the first quarter of next year, an SP spokesman told BT. But first, work on their Seafront project upper and lower shafts must be completed. In response to BT queries, the spokesman said work on most of the 18 upper shafts will be done by the end of next month; this will be followed by drilling and blasting of the hard rock to build the lower shafts. The tunnels will not encroach on any private properties. An Integrated Data Monitoring System (IDMS) will track the effects of the excavation and tunnelling on the surrounding ground. This is the first time an IDMS of this scale is being used in a construction project here, said the spokesman. Tunnel boring machines, the main components of which are from Japan and Germany, are expected to arrive here from December, in time for the actual tunnelling work from early next year. SP simultaneously started work on the 16.5 km east-west tunnel and the 18.6 km north-south tunnel last December. It carved out the work into six contracts and handed these out only to contractors experienced in tunnel-boring because of the expected complications in building the tunnels. The contractors are Obayashi Corporation, Nishimatsu Construction-KTC Civil Engineering and Construction, Hyundai Engineering & Construction, Samsung C&T Corporation and SK Engineering & Construction. Apart from the depth at which the work will take place, the space down there will offer a tight turning radius of only 75 metres at some points – narrower than the 200 metres in MRT tunnels. Another challenge will come from the varying types of rock below ground. The IDMS will integrate all instrumentation and monitoring data from various sources into a single web-based platform and enable easy access and review of data as construction progresses. The SP spokesman said: “This will ensure that ground settlements, movements and vibrations caused by various underground tunnelling construction activities are monitored to ensure minimal impact on existing adjacent buildings, structures and utilities. It is a proactive approach that will detect problems before they escalate into bigger issues, she added. Measuring 6 metres wide and up to 60 metres deep, the tunnels will accommodate 400 kV power circuits, which can carry the volume of electricity being generated and transmitted today. Singapore had started out with 66 kV high-voltage power circuits, and subsequently upgraded to the current 230 kV ones. The east-west tunnel, running from Ayer Rajah to Paya Lebar, is expected to be completed by 2017; the north-south tunnel, stretching from Gambas to May Road, will be done the following year.

The year turned out to be a very memorable one not only for us at SP but also for Singapore as we journeyed through unprecedented developments, surmounted difficult challenges and recorded notable achievements while continuing to forge ties that further advanced our mission to improve quality of life. 2015 was a double joy for us as we celebrated our 20th Anniversary while Singapore celebrated her 50th birthday. We proudly participated in all major National Day events including the historic National Day Parade and made sure all related events were backed by 24/7 power reliability. Our SG50 Gift of Power to Singapore provides the public with power on the go, with free charging of mobile devices at 200 locations island-wide. We continue to give back to the community through our 20 Good Deeds of community service and volunteer outreach programmes to commemorate our 20th anniversary, which was very well received and exceeded expectations. The SP family stood with the nation at the passing of Singapore’s founding Prime Minister Lee Kuan Yew, joining millions in the tremendous outpouring of tributes to a luminary who has and will continue to inspire generations. To commemorate the first year anniversary of his passing, we collaborated with Mapletree Investments to publish and distribute a workbook, “Follow That Rainbow, Go Ride It” for secondary school students so that they may build on Mr Lee’s legacy to create an even brighter future for themselves, their families and the country. At SP, we are focused on meeting the needs of future generations of customers in a rapidly changing environment, through innovation and collaborations within the power industry and across sectors. Our unwavering commitment is to uphold the standing of Singapore’s power network as one of the top utility networks in the world, and to create sustainable solutions to improve quality of life. FINANCIAL PERFORMANCE For the financial year 2015/2016, the Group’s net profit was S$924 million. Strong operating performance from our transmission and distribution businesses contributed to this result. There was also higher profit contribution from our investment in Australia, mainly AusNet Services, largely due to one-off tax consolidation benefit arising from a corporate restructuring. Despite a volatile market backdrop, we successfully raised a benchmark 10-year US$700 million S144A bond in November 2015 to refinance maturing debt and fund future capital expenditure. This issuance, our first S144A bond since 2003, was well received 6 by a diverse range of high quality investors, including a strong participation from US institutional investors, resulting in a strong order book of US$1.4 billion. The strong endorsement by investors reflected their confidence in our high credit quality. POWERING SUSTAINABILITY Singapore’s electricity and gas networks have remained among the world’s highest-rated in reliability and efficiency. Last year, the average electricity customer experienced 0.56 minute of electricity interruption. We achieved zero transmission minutes loss, which means there was no supply interruption at the electricity transmission network level. The average gas customer experienced 0.16 minute of gas interruption. We continued to expand our gas transmission network by adding pipelines to ensure that gas is delivered to our customers safely and reliably. District cooling is another important area where we are leading the charge in sustainable development, as buildings are among the biggest energy consumers in Singapore. Singapore District Cooling (SDC), a wholly owned subsidiary of SP, owns and operates the world’s largest underground district cooling network. In March 2016, the entire Marina Bay district cooling network was commissioned with the completion of the third phase of capacity expansion. Its two main plants and one satellite plant supply chilled water for air conditioning in the Marina Bay financial district, including Marina Bay Sands Integrated Resort, Marina Bay Financial Centre and Gardens by the Bay. Customers have reported energy savings of up to 40 per cent. We look forward to welcoming new customers in the district, and we are currently working with the Urban Redevelopment Authority and Building and Construction Authority to expand the use of district cooling in Singapore. In China, we are building a district cooling system for CapitaLand’s Raffles City development in Chongqing. In our effort to maximise land utilisation to meet Singapore’s growing urban environment, our first 66kV underground transmission substation at Changi Business Park was commissioned on 31 December 2015. We will continue to explore more underground power installations for the future. Our cross island Transmission Cable Tunnel Project is 85 per cent complete and Jurong Island- Pioneer Cable Tunnel project is 40 per cent complete. The tunnels are a cost-effective long-term solution for the provision of reliable, quality electricity supply to the future. Our engineering capabilities and commitment to sustainable development in Singapore received a major endorsement when the public voted three of our projects as Singapore’s top 50 engineering feats. All three SP entries to the Institution of Engineers Singapore’s competition made the list – underground district cooling system, underground cable tunnels and world-class electricity grid. AT YOUR E-SERVICE We continue to uphold our “One Call, One Click, One Stop, in One Day” promise to all customers. Besides providing convenience to our customers, we empowered them in our broader drive for sustainability and in using energy efficiently, while helping them bring down the cost of their utilities. Following a successful pilot programme last year in which 27,000 households had access to e-services that allowed them to keep closer tabs on their energy and water consumption, we have rolled out the service to all our customers. With the service, our customers will be able to view their consumption patterns, set their own consumption targets, and reduce their energy consumption. Since May 2016, our SP Services mobile application, website and e-bill summary have included user-friendly features that allow consumers to audit their own energy consumption and even compare it against their neighbours’. It also provides tips for efficient energy and water use. These new features have been incorporated into our newlydesigned SP Services bill which is simpler and clearer, with information at a glance, easy ways to track consumption, and ways to bring down both consumption and cost. 7 CHAIRMAN’S MESSAGE In supporting the move towards full retail competition and enabling customers a greater choice of power retailers, SP has rolled out approximately 84,000 Advanced Metering Infrastructure meters which measures contestable customers’ usage at half-hour intervals, to help consumers decide on the best service provider for them. So far, we have achieved a read rate of about 99.7 per cent. PEOPLE POWER Over the course of the year, we continue to build on investments we have made in growing the talent pipeline. We have since 2012 awarded more than 100 scholarships to students with a passion for engineering in the energy sector as we seek to broaden our talent pool. Our Engineering Development for Graduates (EDGE) programme, which was started in 2013, has provided 121 fresh graduates with structured training and job rotation to critical operations to gain broad-based exposure and diverse technical expertise. We remain committed to staff upgrading, handing out 419 sponsorships for SP staff to pursue part-time education since 2002, including four who are pursuing their Master’s degree overseas. Towards strengthening our engineering bench, we now have 100 certified Professional Engineers, who make up 18.5 per cent of our total engineering pool, above the national average of 1.7 per cent. We will continue to sponsor the certification journey for more of our engineers. SP has made strides in creating a culture of innovation among our employees. On the digital frontier, we have made technology tools available to all staff, automating processes and approvals, and streamlining workflows. This is part of a continuing effort to create an agile, collaborative and mobile workforce. We embarked on new projects such as an enhanced electronic vendor procurement management system, a condition monitoring app to ensure power supply reliability and a cable and gas pipeline patrolling app. These initiatives helped to boost productivity and improve the quality of life at work. We also set out to devise leaner work processes and undertook more than 100 improvement initiatives in 2015, with projected savings of S$16 million when implemented. These were ground-up initiatives by staff which contributed towards more productive ways of working. We are boosting our capabilities from within, through initiatives that allow our employees to take charge of their own development. With the launch of the iTalent human resource tool in January 2016 and its inclusion on their mobile tablets, employees have easy access to learning and development resources, channels for engagement and feedback, and their performance appraisals. This promotes “development on the go”, allows employees to stay engaged, and will have a positive impact on productivity. ACCELERATING GROWTH We are seeing rapid changes in the power industry. On the horizon, we foresee that sustainability, energy technology and urbanisation are key global trends that will shape the future of our business. We have developed strategies to leverage on solutions and innovations that can help us to better serve customers’ needs and lifestyles. Supported by Singapore’s Economic Development Board, SP launched the S$30 million SP Centre of Excellence in April 2015 to drive the innovation and commercialisation of nextgeneration network technologies. During the Singapore International Energy Week in October 2015, the SP Centre of Excellence entered into a Memorandum of Understanding with the Omnetric Group, 3M Singapore and the Economic Development Board under the Singapore Power Energy Advanced Research and Development programme to build and pilot next-generation technologies to enhance Singapore’s power value chain. Other initiatives that we are working on include converting our fleet of vehicles to electric vehicles and developing solar and storage solutions at our facilities. We are also going underground – building underground substations and housing our network cables deep beneath in the cable tunnels – to optimise space in our landscarce city. SAFETY AS A PRIORITY Safety affects the well-being of our workers as well as the public, the 8 working environment and project costs, and remains an important focus for us. Our Gas Safety Awareness campaign, launched in August 2015, aims to raise public awareness on the risks and ways to prevent accidents arising from gas fires. The campaign leverages touch points such as the Ministry of Manpower Foreign Domestic Worker training sessions, community events, grassroots platforms and schools. We have participated in 13 community road shows to date. The campaign videos have garnered more than 1.19 million views on YouTube as of March 2016. We are happy to have seen our efforts in this area show tangible results. Of particular note is our Lost Time Injury Frequency Rate (LTIFR), which dropped to 0.77 per million man-hours in FY15/16, a significant improvement on 1.10 the year before. This improvement reflects the commitment to safety that we have in place and the constant improvements we have made in our safety transformation journey. It has also brought us closer to our “world-class” target LTIFR of 0.57 per million man-hours several years ahead of schedule. Our contractors play a critical role in creating a safety culture for all. In the past year, we established targeted programmes and processes to help our contractors uphold safe work practices. The Hand Safety Campaign exemplifies our efforts to engage contractors to improve safety processes. The campaign was launched in September 2015 to promote safe practices of hand-related operations and prevent hand and finger injury among workers. Activities carried out include conducting in-house training on hand safety to increase awareness. SP PowerGrid’s Cable Tunnel team’s Gold Award for Health and Safety 2016 from the Royal Society for Prevention of Accidents (RoSPA) affirmed our steady efforts. The award is an endorsement of the Cable Tunnel team’s strategic initiatives, the support of management and our collective passion for raising safety standards in the tunneling industry. Our shared commitment to safety, and ensuring we are all aligned in terms of safety requirements and expectations, means our workers are safe, our projects are well managed, and our risks are contained. THE POWER OF GOOD SP celebrated SG50 by presenting Singapore with a Gift of Power in July 2015, providing free charging of mobile devices at 200 locations island-wide. Just as SP serves the nation by striving to keep the lights on 24/7, the Gift of Power affirms SP’s commitment to always be there for Singapore, by helping Singaporeans to stay connected. This was one of two major projects SP undertook to celebrate Singapore’s 50th birthday. The other was the Love from the Stars charity gala dinner and concert in May 2015 featuring international artistes like Jackie Chan. The event raised close to S$6.4 million for 6 charities, which provided assistance to about 160,000 beneficiaries. These two projects were part of 20 Good Deeds, a volunteerled initiative to give back to the community through 20 acts of community service for SP’s 20th anniversary in 2015. These activities included programmes to encourage energy-efficiency, outings with underprivileged children and visits to homes and activity centres for the elderly. The activities were driven by our staff volunteers – SP Heart Workers – and every business unit spearheaded at least one good deed.

It also captures how Mr Lee led his life through extracts from newspaper articles and interviews, quotes and historical photographs. We hope that new generations of Singaporeans will be inspired by Mr Lee’s character, values and vision, and contribute to making Singapore shine even more brightly. 23 RELIABILITY POWERHOUSE • Commissioned the world’s largest underground district cooling network in Marina Bay in March 2016. Singapore District Cooling helps customers achieve up to 40 per cent in energy savings • Remained among the world’s highest-rated utility companies in terms of reliability and efficiency, with our customers experiencing just 0.56 minute of electricity interruption and 0.16 minute of gas interruption in FY15/16 • Three SP projects were voted among Singapore’s top 50 Engineering Feats in the Institution of Engineers (IES) Singapore’s IES-SG50 competition – Our World Class Electricity Grid Reliability, District Cooling System for Marina Bay and Cross-Island and Jurong Island-Pioneer Cable Tunnels Singapore District Cooling helps customers achieve up to 40% in energy savings From Left Benjamin Ng Jet Hon Executive Engineer, Network Management, Gas Operations Ken Kong Chee Keen Principal Engineer, Network Management, Gas Operations RELIABILITY POWERHOUSE R eliable energy infrastructure is vital for the smooth running of households, businesses and cities. In Singapore, ensuring that this service is dependable, uninterrupted and safe is a key priority for SP, and a critical component of our business strategy. We continually invest in improving our systems and processes, and seize opportunities to create sustainable growth. In FY15/16, we broke new ground with a number of major projects. We completed our first underground substation at Changi Expo and commissioned the Changi East and Upper Jurong II 230kV substations. We also commissioned the world’s largest underground district cooling network, run by our subsidiary Singapore District Cooling (SDC), which keeps Marina Bay cool. We upgraded and expanded critical power and gas networks, and network monitoring systems. We also took steps to ensure stable and reliable power supply for the future with major new transmission projects planned, and are on track to complete our Transmission Cable Tunnel Project by 2018. Our commitment to fulfilling our reliability promise has helped us record among the lowest incidence of power and gas supply interruption in the world. Last year, our customers experienced an average 0.56 minute of electricity interruption. We achieved zero transmission minutes lost, which means there was no supply interruption at the electricity transmission network level. Our gas customers experienced an average 0.16 minute of gas interruption. We continually look for innovative and cost-effective Minister for National Development Lawrence Wong toured the Singapore District Cooling’s Marina Bay plant during the commissioning event on 3 March 2016. 26 ways to do our work faster, better and more safely, and empower our staff with the knowledge they need to increase productivity and bring value to our customers and stakeholders. COUNTING ON SOLID NETWORKS Cooling down the Bay In March 2016, we commissioned the entire Marina Bay district cooling network following the third phase of capacity expansion. With the expansion, SDC now operates the world’s largest underground district cooling network. Buildings consume some 30 per cent of Singapore’s energy, and air-conditioning accounts for half their consumption. SDC’s services translate into energy savings of up to 40 per cent for customers. It also means that gardens, restaurants and infinity pools can take the place of unsightly rooftop cooling towers. The plants have a total installed capacity of 217MW, and serve 1.7 million square metres of Gross Floor Area. This idea, more than a decade in the making and supported by a robust network design, strong engineering team and high operational standards, contributes to realising the vision of an environmentally sustainable Marina Bay – and ultimately, a sustainable Singapore. Even as we look forward to welcoming new customers in the district, we are already working with the Urban Redevelopment Authority and Building and Construction Authority to expand the use of district cooling in Singapore. Overseas, we are building a district cooling system for CapitaLand’s Raffles City development in Chongqing, China. Once completed, the system will enable the development to achieve up to 50 per cent energy savings, and reduce utility cost by about S$30 million over 20 years. Raffles City Chongqing is the largest single investment by any Singapore firm in China, with total development cost expected to be around S$4.2 billion. Powering for Growth On 31 December 2015, we commissioned our first underground transmission substation, the Changi Expo 66kV substation, at Changi Business Park. It will provide 66kV intake supply to the MRT Downtown Line 3 Extension, and to multinational corporations and industries in the area. To meet growing electricity demand in the Jurong and Changi areas, 230kV substations were commissioned in Upper Jurong II and Changi East in June 2015 and July 2015, respectively. Enhanced distribution management We have upgraded our Distribution Management System (DMS), a critical system for remote monitoring and control functions for our entire 22kV network of 6,600 substations. The system also provides monitoring and control for 3,420 substations in our 6.6kV network. Following the upgrading, the DMS now includes a biometric access control system. Engineers can use artificial intelligence instead of desktop planning exercises to run contingency scenarios for equipment maintenance. The system also automatically produces and broadcasts reports on network faults as soon as they occur. Since June 2015, we have progressively implemented remote monitoring and control capabilities at our 6.6kV substations. The system has been upgraded to protect against cyber-attacks, improve system robustness, and streamline network database updating processes. 27 RELIABILITY POWERHOUSE Expanded Gas Network Infrastructure We expanded our gas transmission network towards Senoko in the North. Approximately 14km of pipelines – from Jalan Bahar to Mandai and the Mandai Offtake Station II – were completed and commissioned in March 2016. Another 12km of pipelines – from Mandai to Senoko and the Woodlands East Offtake Station – will be constructed by December 2016. This enables the safe and reliable delivery of gas from the Singapore LNG Terminal located at Jurong Island to existing and new customers in the northern part of the island, including power plants. More Capital Projects To meet customers’ growing power needs and ensure timely renewal of aging assets, we plan to roll out several major transmission projects over the next five years. These include the development of a 400/230kV substation at Jurong Island, and the progressive replacement of 230kV circuits through the North-South and East- West underground cable tunnels. The new West Jurong 400/230kV Substation, to be commissioned in December 2018, will reinforce our 400kV network and help meet the growth in demand in the western part of Singapore. This will facilitate and increase the transmission of power from Jurong Island to the mainland. Technical Officer Mohamad Ridhwan Bin Mansor conducting a gas leak survey as part of our regular maintenance to ensure the integrity of our network. Interconnecting Gas Networks Singapore’s two medium pressure gas networks that serve customers in the Jurong and Tuas areas were successfully interconnected in November 2015. The interconnection improves network supply reliability, and promotes contestability among gas shippers and retailers. Transmission Cable Tunnel Project Milestones The North-South and East-West cable tunnels, which will allow the efficient installation and replacement of underground cables, sit below the MRT underground system and are unprecedented in scale. When completed in 2017 and 2018 respectively, they will provide a cost-effective, long-term solution for the supply of reliable, quality electricity to future generations of customers. We have completed close to 85 per cent of the tunnelling for the project, with distances of 15,327m and 13,643m achieved on the North-South and East-West tunnels respectively as of March 2016. 28 Our engineers behind the Cable Tunnel project – one of three SP projects named among Singapore’s top 50 engineering feats.

Close to 40 per cent of the Jurong Island-Pioneer Cable Tunnel, which connects the 400kV substation at Jurong Island to mainland Singapore, has also been completed. In all, we have achieved seven tunnel boring machine (TBM) breakthroughs, negotiating the tightest tunnel curvatures in Singapore. On 31 January 2016, we made history with the first ever docking of two TBMs in Singapore, 60m under the Holland Village MRT station. All tunnelling for the remaining 11 TBM drives are scheduled for completion by March 2017.

At the right place, right time The upgrading of our SP Services Wireless Workforce Management System (WWMS) was completed in December 2015. The WWMS is an integral part of our service delivery operations. It ensures that our technicians arrive at the right location at the right time for supply activation or termination, installation inspection or meter readings. With the latest upgrade, our field services teams can use the WWMS app on their iPads to get more information on the job while on-the-go. New features, including camera and video functions, have also improved productivity, allowing site photos to be uploaded directly into the system via tablets. Our engineering feats Three SP projects – underground district cooling system, underground cable tunnels and world-class electricity grid – were voted by the public to be among Singapore’s top 50 engineering feats. This is an endorsement of our engineering capabilities and our commitment to Singapore’s sustainability drive. This competition was organised by the Institution of Engineers Singapore as part of its 50th anniversary celebrations. Leading by example SP’s Senior Management team are on a 24-hour roster and will be activated to go onsite when there are serious electricity supply disruptions, regardless of the cause of the incident. Together with our engineers, they will be ready to tackle issues and address concerns at the site. Green enterprise data centre Our SP Services enterprise data centre received three certifications – BCA-IDA Green Mark, SS564 (Energy & Environment Management System), and ISO50001 (Energy Management). The data centre was designed and built with environmentallyfriendly features, adopting industry best practices and the latest technologies to reduce energy consumption and its carbon footprint. Prominent green features include a cold aisle containment system, highly efficient power equipment, precision cooling and chilled water systems, and the use of natural lighting and LEDs with motion sensors. These features will reduce power consumption at the data centre by 15 per cent every month. PRODUCTIVITY A better way to work We have created a suite of training programmes at our Lean Academy to educate and equip our staff with the necessary skill sets to eliminate wasteful work processes. More 30 than 95 per cent of our staff have completed the DOWNTIME online training programme, which addresses waste that could be caused by Defects, Overproduction, Waiting, Not utilising talent, Transportation, Inventory, Motion and Extra processing. Customised workshops and forums strengthened our managers’ and leaders’ understanding of Lean techniques, which seek to maximise customer value while minimising waste. Armed with Lean insights, our staff shared ideas and best practices on the VOICES staff suggestion portal. More than 3,700 ideas were submitted and 100 improvement initiatives pursued in 2015. They are expected to collectively save the company S$16 million. Delivering Sustainability In September 2015, we embarked on an ambitious pilot project – Project Maximus – to embed Lean tools and practices into our operations over a nineweek induction period. The project kicked off at our Pasir Panjang District Office Inventory Management store. Staff came up with 26 ideas and six improvement projects that would potentially lead to a 5 per cent reduction in terms of man-hours, and S$1.3 million in outright savings for SP. Following the successful pilot, we identified 32 core sections that will undergo the same programme over the next two years. To sustain SP’s transformation into a Lean organisation, we integrated productivity with staff reward programmes, and simplified existing policies to make it easier to recognise staff efforts. Process Automation To improve turnaround time for cable preparation during installation, maintenance and repair work, SP invested in an Automated Coiling Machine. This significantly reduces the amount of time needed to prepare cables, and requires only a fraction of the manpower to perform the task manually. The machine comes with a hydraulic lifting mechanism and a digital measuring system, improving both safety and the accuracy of the coiled lengths to minimise re-coiling. Supporting national events We supported several national and major events in FY15/16. Close to 500 officers from Electricity and Gas Operations were mobilised for standby duty during National Day and the SG50 celebrations, the National Day Rally, the Formula 1 Singapore Airlines Singapore Grand Prix, the 28th SEA Games Singapore 2015, and the 8th ASEAN Para Games Singapore 2015. Our teams were involved in planning, discussions, practices and rehearsals to ensure there were no electricity or gas interruption during these events. Another poignant example was when our officers were also at hand to support the lying-in-state and state funeral of founding Prime Minister Lee Kuan Yew as we mourned alongside the nation on his passing in March 2015. The Automated Coiling Machine supports our productivity process by reducing the manpower required and time taken to re-coil cables. 31 DRIVING INNOVATION • Developed 17 apps, including iTalent and the Condition Monitoring inspection app, to boost productivity and collaboration among staff • Rolled out an e-biz portal to make it more convenient for potential partners to work with us • SP Services’ mobile app for customers picked up the Gold Award at Mob-Ex 2016 and was named “Best Customer Engagement Project” at Asian Utility Week 2016 S$3.4 million Projected productivity savings over two years as a result of the new electronic and digital tools for all staff.

Each I wave of progress propels the global economy forward and delivers improvement to the quality of life of our customers. The first industrial revolution was driven by steam power. The introduction of electricity transformed the way people live. Innovation has continued to provide us with significant advances in electronics, computing, digital networks and communications. We are starting to see the potential of sustainable energy. SP is committed to remain at the forefront of these developments and is driving innovation in every part of our operations so that we are able to continuously improve the quality of life for consumers. In the past year, as part of our innovation roadmap, we continued to digitalise SP to put power in the hands of our customers, partners and employees by providing them with the tools that give added convenience, increased productivity and support our drive towards greater sustainability. Beyond actively integrating new technologies for better customer experience and system performance, we are going a step further, already considering the future needs of our customers. To that end, we set up the SP Centre of Excellence to partner companies, research institutes and other innovative parties to co-develop and commercialise next-generation energy network technologies and solutions.

SP is using its expertise in providing safe and reliable power in the area of telecommunications, providing consumers more choice in this age of increasing data flow. Together, SP’s innovation efforts in energy and communications networks will form the backbone that supports Singapore’s Smart Nation Vision. DIGITALISING SP Award-winning mobile apps We have introduced a number of mobile apps for our customers and staff. Customers have benefited from the SP Services mobile app, which enables them to monitor their utilities consumption patterns, and compare these patterns against those of their neighbours and the national average. They are also able to conduct their own home utilities audits, get energy-saving tips and set targets for lower consumption. The app picked up a Gold Award at Mob-Ex 2016 in the “Best Mobile App – Community Service” category. The Mob-Ex Awards recognises mobile marketing excellence across South Asia, Southeast Asia, and Australia and New Zealand. The app was also named the “Best Customer Engagement Project” during Asian Utility Week 2016, which was held in Bangkok. Providing convenience to our partners We rolled out our own e-biz portal, the Supplier Relationship Management system. Our vendors, developers and government agencies can expect greater convenience and better service when they process tenders, approvals, permits and other documents. Putting Power in the Hands of our Staff A key initiative for our 20th anniversary was to empower every staff with electronic tools that improve the way they work and interact with colleagues and partners. All 3,700 SP staff now have an electronic tablet which provides them with information at their fingertips, enabling them to work on the go. Projected productivity savings from this effort is estimated at S$3.4 million over two years. Our union, the Union of Power and Gas Employees (UPAGE), is a strong advocate of this initiative, which will also see staff benefit from a better quality of life at work. The iPad tablet has also allowed staff to access a number of productivity apps. We have launched a Cable and Gas Pipe Patrolling app, a Gas Meter Replacement app and a Condition Monitoring app. The Cable and Gas Pipe Patrolling app makes earthworks site monitoring more efficient by enabling staff doing patrols and site checks to create real-time recordings and instantly upload time-stamped photographs into a central database, facilitating investigation work. The mobile app also provides access to site maps and the required forms. With the Condition Monitoring inspection app, field staff can submit their inspection records immediately. They can also access live data to guide decision-making in the field. The app, implemented from 1 February 2016, is expected to achieve cost savings of approximately S$300,000, or 404 man days, during its projected lifespan of five years. In all, 17 apps have been developed since August 2013 and more are in the pipeline to help drive the efficiency of our operations. Besides boosting productivity and collaboration, better information and communications channels have helped improve employee engagement. The tools have also sped up the adoption of SP’s customised apps such as SParkle, a peer appreciation and recognition software, and iTalent, a talent management app that allows a wide range of functions, such as performance appraisal, to be done anytime, anywhere. Promoting knowledge exchange Having their own tablets also means our staff can easily access our newly-launched Knowledge Management (KM) System, an online social community where SP staff can share knowledge and discuss work-related topics. Our engineers collect and collate content on the job, including standard processes and procedures, case studies and lessons learnt. The KM System allows for this knowledge to be shared, promoting a culture of continuous learning. Knowledge from more experienced SP engineers benefits the newer members of our community. 35 DRIVING INNOVATION Some 74 online communities had been formed as of March 2016, including the Professional Engineers Guild House, which provides peer support for aspiring engineers working towards professional certification; the Safety Community, which promotes awareness around safety issues and shares observations and audits; and the Cyber Security forum, where discussions about IT risks and threats on the Internet take place. The system was recognised as the “Most Innovative Project for Energy Sector” by OpenText, a global leader in Enterprise Information Management solutions, in November 2015. Documents Registry for better accountability In line with our mission to proactively improve and add value through systems and processes, SP launched the SP Group Critical Documents Registry last year with representatives from each SP business unit, ensuring all critical documents within the SP Group are properly accounted for and stored, and can be easily traced in a common repository. This improves efficiency and productivity in tracking and retrieval, and ensures accountability. Leveraging on data analytics The Data Analytics Task Force was set up in October 2014 for various business units to develop Proof of Value (PoV) projects that use Data Analytics Tools. Our Data Analytics Resources Lab, helps take the successful PoVs to the next stage of development. These projects include Network Management, Geospatial Gas Leak Location Analysis, and Customer Contract and Debt Recovery, among others. One success story is the Geospatial Gas Leaks Location Analysis project, with a pilot completed in February 2016. Using Geospatial Data Analytics Tools, the Gas Asset Strategy and Condition Monitoring Section built a prototype that analyses historical data of gas leaks to determine areas that have a higher propensity for recurrence. This helps to optimise inspection resources. The results of this project are being adopted in gas leak inspections. Consolidating asset management systems We completed the first phase of Project NOVA, an enterprisewide asset management system, in January 2016. The system consolidates and automates manual work processes maintained by the different business units. NOVA will enable remote access of information via mobile apps, and increases staff productivity and effectiveness of workflow processes. It also paves the way for the development of a future-proof system that will drive business process automation within the organisation. SEEING POTENTIAL Next-Generation Solutions In April 2015, we launched the SP Centre of Excellence (CoE), a S$30 million collaboration with the Economic Development Board to drive the innovation and commercialisation of nextgeneration energy network technologies. Mr Neo Kim Hai (middle), Head, Knowledge Management, receiving the ‘Most Innovative Project in the Energy Sector’ award at the OpenText Elite Awards 2015. SP CoE will work with industry partners to co-develop, pilot and proof emerging technologies in SP’s networks. This collaboration does not just develop internal capabilities, but also helps SP’s partners bring their products and solutions to market. Our partners also benefit from SP’s operational expertise, and are able to test their products and solutions in actual networks, in real-time and with real consumers, measure the impact of these innovations, and commercialise them. It also brings to market solutions that improve our customers’ quality of life. Current areas being worked on include energy network digitisation, smart energy management, network sensing and big data analytics. Leveraging power experience for fibre networks Besides providing Singapore with reliable power supply, SP is also providing greater choice as a trusted partner of enterprises in 36 the telecommunications industry. Our telecommunications network arm SP Telecommunications (SPTel), whose extensive optical fibre network runs alongside SP’s nation-wide power lines, will offer connectivity and enabling-technologies to telecommunications carriers, retail service providers, data centres and enterprises. SPTel’s customers include carriers such as China Telecom and HKT, as well as enterprises such as MediaCorp. Through its extensive OpticNet dark fibre network, SPTel also allows data centres, landlords and property developers to strengthen their offerings to their end-customers – enabling organisations, from emerging InfoComm companies to e-commerce brands and entrepreneurs, to be futureready. Its SmartConnect service combines the power of Ethernet with the reliability of optical fibre to optimise connectivity for high quality, secure and speedy connections – whether between people and businesses, or between data centres and key interconnection hubs. In addition, SPTel will provide fibre links to the Woodlands Causeway and the Tuas Second Link, adding to diversity with off-shore connections outside of Singapore. DigiHub, Equinix, Global Switch, 1Net and Kingsland. Seeding the sustainable future SP actively promotes renewables and innovation in technology developments. Among our initiatives is a S$1 million, 5-year sponsorship to help Singapore Polytechnic build solar vehicles and participate in three editions of the World Solar Challenge in 2015, 2017 and 2019. Just three weeks before their scheduled departure to compete in the 2015 edition of the 3,000km solar car race across Australia, the Singapore Polytechnic team’s selfbuilt solar car, SunSPEC4, was destroyed in a fire. With additional funding and logistical support from SP, as well as our undertaking to air freight the SunSPEC4 to save time, both the team and their car were at the starting line on time to be flagged off. SP’s staff, who are also alumni of the polytechnic, travelled with the SunSPEC team to provide additional support and advice on logistics and safety. SP also sponsored a satellite phone with call and data features so the team could keep in touch with families and friends even when in remote areas. SP also launched the SunSPEC Polytechnic & University Sponsorship scheme, that offers SP academic sponsorship to the Singapore Polytechnic students who were part of the SunSPEC solar car team last year. The SunSPEC academic sponsorship scheme recognises the determination, tenacity and strong engineering passion of the students, and expands our pool of enthusiastic future engineers. As the role of data centres grows, with business applications becoming more data-intensive and requiring more bandwidth, SPTel is on track to meet the increasing demand for connectivity, speed, diversity and reliability by creating a data centre fibre fabric linking the nation’s key data centres. To date, SPTel’s customers include Keppel Singapore Polytechnic’s SunSPEC team, sponsored by Singapore Power, at the finishing line of the World Solar Challenge 2015 in Adelaide, Australia. 37 STRIVING FOR SERVICE EXCELLENCE • Customers benefit from our “one-call, one-click and onestop service in one business day” promise when they apply for utilities services • SP Services mobile app empowers customers to be more energy-efficient by helping them track consumption, compare it with their neighbours and set goals to save energy • 84,000 smart meters installed as of April 2016, out of a total 280,000 by 2021, in preparation for full liberalisation of the electricity market 1.4 million The number of customers we serve each month, including fielding some 80,000 calls. Our team reads a total of 3.6 million electricity, water and gas meters every other month. We also process some S$6 billion in utility payments annually. Customers will receive their new utilities bill in August 2016. STRIVING FOR SERVICE EXCELLENCE The app won the Gold Award – Community Service at the 2016 Mob-Ex Awards, a premier event that celebrates mobile marketing excellence across South Asia, Southeast Asia, Australia and New Zealand.

CLEANER, CLEARER BILLS Melvin Chan, Customer Care Officer, helping new condominium homeowners open their utility accounts on-site when they collect their keys. F rom individuals and families to companies and industrial customers, ensuring a convenient, efficient and hassle-free service experience has always been a priority for SP. Whether through technology and innovation, or simply by listening to our customers, we continually strengthen our service culture and strive to enhance every encounter at our service touchpoints. This includes simplifying our bills so they are clear, helping customers make energy-efficient choices, putting utilities management at their fingertips, and providing easy access to assistance and self-help channels. UTILITIES AUDITS AT YOUR FINGERTIPS Following a successful pilot run, we rolled out enhanced e-services to all customers, designed to help them adopt more energy-efficient practices. From May 2016, all our customers are able to keep tabs on their energy and water consumption patterns more easily through the SP Services mobile application, website and email bill summary. The app, available from iTunes and the Google Play Store, lets customers compare their current consumption against that of their neighbours, the national average and their own past consumption. They can also conduct their own home utilities audits, get energy-saving tips, and set targets for lower consumption. Customers now receive their utilities bill in a new design, intended to promote more efficient utilities consumption and help customers better understand billing information. Past consumption and comparisons with that of neighbours and the national average are also available at a glance. The new bill offers utilities-saving tips and advice that can help customers become more energy and water efficient. Several different versions of the new design were tested with customers before the final design, which is simpler and clearer, was selected. EASY UTILITIES APPLICATION FOR NEW HOMEOWNERS Setting up a new utilities account with SP Services has become even more convenient. Customers can apply for utilities services by making one call to our hotline, one click to our website, visiting any of our three customer service centres for one-stop services, and having their utilities connected in one business day. New homeowners can now also open their utility accounts on-site at their new condominiums when they collect the keys. This means having immediate access 40 Thomas Goh (standing), Assistant Director, manages call centre operations, which includes handling about 80,000 phone calls monthly. to electricity and water without having to contact SP Services to open an account and then booking a separate appointment for the utilities to be activiated. This initiative has been very well received. ENGAGING COMMERCIAL AND INDUSTRIAL CUSTOMERS As part of ongoing efforts to build a stronger partnership with our key customers, SP PowerGrid conducted six Power Quality Interest Group (PQIG) meetings between October 2015 and February 2016 for voltage-sensitive customers from seven sectors: Semiconductor & Electronics, Pharmaceutical, Petrochemical & Chemical, Banking, Essential Services, Tourism & Hospitality, and Data Centres. The newly-formed Data Centres cluster was added to the PQIG in view of the sector’s rapid growth. The new cluster’s members had their first meeting in December 2015. GEARING UP FOR FULL LIBERALISATION OF ELECTRICITY RETAIL We continue to gear up for full liberalisation of the electricity market in Singapore, scheduled for the second half of 2018. By then, more than 1.4 million consumers, mainly households, will be able to buy electricity from the retailer of their choice or from the wholesale market. The contestability threshold has been progressively lowered since 2014. With the downward revision in July 2015, commercial and industrial consumers with an average monthly electricity consumption of at least 2,000 kWh became eligible for contestability. SP continues to work closely with new electricity retailers, helping them with the registration and activation of customer accounts. We are also making major upgrades to our systems, including equipping them with the technology and automated processes necessary to handle a higher volume of dealings between consumers and electricity retailers. More Advanced Metering Infrastructure (AMI) meters, or smart meters, will be deployed to cope with the larger number of opt-in customers. A total of 280,000 smart meters are expected to be installed by 2021, up from about 84,000 as of April 2016. AMI meters are capable of measuring contestable customers’ electricity consumption at half-hourly intervals, allowing customers to better manage their consumption and lower their electricity bills. Beyond that, more communication equipment such as Access Points and Relays will be installed to expand and strengthen the existing Radio Frequency communication network. This will not only support retail competition but also future Smart Grid developments. 41 AN ENERGISED WORKPLACE • Strengthened our engineering bench through sponsorship for Professional Engineer certification.

For new technical staff, we launched the Learning Through Technical Accelerated Programme (LEAP), which will provide them with structured training before they embark on their jobs. We awarded 419 sponsorships to staff to pursue further education, including to four staff members for their Master’s degree in the United Kingdom. Of these, 54 per cent have been appointed to positions of higher responsibility, having performed well in their jobs. We have invested more than S$2 million to date in upgrading our staff. We developed a World Class Engineering Bench by complementing core engineering work with continual learning. Mentors and fellow engineers share their experiences with their younger counterparts on SP’s Knowledge Management Portal. We continue to offer our engineers sponsorship for their Professional Engineering certification. To date, we have 100 certified engineers who make up 18.5 per cent of our total engineering pool, above the national average of 1.7 per cent. This makes us the organisation with the most number of certified engineers in-house. Our investment in the energy sector starts early. Most recently, we committed ourselves to granting S$10,000 in awards over five years to Singapore University of Technology and Design (SUTD) students who demonstrate outstanding performance in their Electric Power Systems and Design module. This is in addition to targeted efforts to reach out to students to fuel interest not just in SP but in the energy sector as a whole. A total of 97 sponsorships and book prizes were awarded to students from tertiary institutions. Since 2012, we have also awarded more than 100 scholarships to students with a passion for engineering in the energy sector. ITALENT AND SPARKLE In January 2016, we rolled out iTalent, a user-friendly App that allows our staff to take charge of their career development. Accessible via the office workstation or SP-issued iPads, iTalent helps employees identify 45 AN ENERGISED WORKPLACE The EDGE programme has nurtured Executive Engineer Gary Tan’s leadership skills. He leads a team of 29 technical staff that deals with Gas Operations emergency responses. their career goals and provides them with “development on the go” – online access to the tools and training that can help them achieve their career goals. Staff can also access their performance appraisals, view their profiles and update their performance on the platform. For managers, iTalent’s dashboard and data-on-demand provides a sound overview of their teams’ progress and where their capabilities stand, as well as opportunities for better communication. We believe that iTalent will result in greater work efficiency and productivity as information becomes more available and accessible. SParkle is a new channel for staff to provide timely recognition to any colleague – peer, supervisor or subordinate. The SParkle App enables staff to send a compliment, word of thanks or commendation at any time, quickly and easily. Since its launch in December 2015, more than 16,000 stars have been sent out. We believe timely affirmation goes a long way in strengthening morale and motivating staff to perform their best. SAFETY FOR EVERYONE Safety also continues to feature prominently on SP’s agenda, with the implementation of safety courses not just for management and staff, but extending to our contractors as well. Such courses ensure that SP is primed to further enhance safety management and practices, and reinforce SP’s safety culture. 46 Since December 2015, more than 16,000 SParkle stars have been awarded by staff in recognition of their colleagues. FUELLING SKILLS DEVELOPMENT As a major player in the energy sector, we established the Singapore Institute of Power and Gas (SPIG) in 2014 as a one-stop training and development centre. SPIG also offers courses to power generation companies to build capabilities within Singapore’s energy industry. We believe such initiatives fuel employee engagement as we build a resilient and adaptable organisation together. We also continued to recognise staff who displayed exemplary customer service through awards, including the annual Super Star Awards. In May 2016, we launched the two-day “Sulphur-Hexafluoride SF6: Benefits, Application and Safe Handling” course to boost knowledge and understanding of SF6, a gas used as an insulating medium in electrical equipment, among the technical professionals and technicians handling it. We also continued to train staff working towards switching certification and began offering a cable jointing expertise course. Attendees of the “Sulphur-Hexafluoride SF6: Benefits, Application and Safe Handling” course learn to measure gas quality. SG50 AND SP20 STAFF INCENTIVES During the year, we rolled out initiatives to motivate staff and boost engagement. To celebrate Singapore’s 50th birthday and to commemorate SP’s 20th anniversary, we launched the SG50/SP20 Bonus. Staff qualified for this bonus when they fulfilled three meaningful engagement tasks on their SP-issued iPads or SP’s mobile apps. They had to award SParkle “Stars” to colleagues exhibiting the SAIL principles, vote on the top three Good Deeds performed by SP Heart Workers and post blog entries on the topics of safety and productivity. 47 PROMOTING A CULTURE OF SAFETY • Lowered our Lost Time Injury Frequency Rate* (LTIFR) – a global measure of safety standards – to 0.77 per million man-hours in FY15/16. We are closer to our goal of attaining the world-class standard LTIFR of 0.57 by FY18/19 • Achieved zero controllable traffic accident for FY15/16 since launch of the SP Services Motorcycle Helmet Camera for all field staff in May 2015 • SPPG’s Cable Tunnel team received the Gold Award for Health and Safety 2016 from the Royal Society for Prevention of Accidents, an endorsement of our team’s efforts to raise safety standards in the tunnelling industry 0.77 per million man-hours our Lost Time Injury Frequency Rate* – a 30% improvement from the year before. * Lost Time Injury (LTI) is a work related injury which results in a person being unfit for work on any day after the day of occurrence of the injury. Lost Time Injury Frequency Rate (LTIFR) is the number of lost time injuries per 1,000,000 man-hours worked. Back row, from left Ragunath Balamurugan S/O Paulsamy Principal Engineer, Group Safety and Health Leslie Neo Wei Han Manager, Group Safety and Health with employees of a contractor’s company. PROMOTING A CULTURE OF SAFETY t SP, safety is a team effort A requiring commitment from every player. It is driven by our management with active staff involvement. Staying free of accident and injury is an important part of our culture, for the public, our staff and our contractors. In FY15/16, we continued to enhance our safety culture and improve our safety performance. We focussed on building long-term partnerships with our contractors, ensuring that they share our safety philosophy and maintain stringent safety standards. SP has more than 6,500 workers from over 130 contractor companies involved in critical transmission and distribution network projects across Singapore. We conducted regular safety workshops and campaigns as well as weekly safety inspections and reviews, and involved workers in our efforts to improve on safety. We continue to raise the standards of our contractor safety management practices and strengthen our partnership with contractors to reduce injuries at work. We are pleased to report tangible results from our joint efforts. In FY15/16, our Lost Time Injury Frequency Rate (LTIFR) was 0.77 per million man-hours worked, a 30 per cent improvement over the previous year. Beyond worker health and wellbeing, alignment with our partners on safety also contributed to the success of our projects and helped us better manage risks.

SAFETY AS A WAY OF LIFE We held our inaugural Group Safety Summit in July 2015 with the theme Safety is Our Way of Life. During the event, Group CEO Wong Kim Yin reiterated SP’s priorities on safety and highlighted our journey to becoming a Safety Champion. He shared our five-year roadmap to attaining the worldclass safety target LTIFR of 0.57. He joined Guest of Honour Mr Hawazi Daipi, then Senior Parliamentary Secretary for the Ministry of Manpower and Education, and SP Chairman Tan Sri Mohd Hassan Marican, in launching SP’s Gas Safety Awareness campaign for the public. We also presented awards for sound safety culture and best practices, as well as for a video competition for the best “safety story” at the Summit. The Cable Tunnel team from Special Projects, SP PowerGrid, walked away with both awards, and won for its video entry, “Family Values”, a story about the importance of safety and the safe return of our employees to their families at the end of the workday. GAS SAFETY AWARENESS CAMPAIGN Launched at the Group Safety Summit, the Gas Safety Awareness campaign aims to equip the public with the knowledge they need to respond safely to a gas leak. It specifically addresses the gaps in gas safety knowledge derived from the findings of a survey conducted in February 2015. We produced and publicised messages through posters and pamphlets, as well as a series of three videos on the “dos and don’ts” in the event of a gas leak. As of March 2016, the campaign videos had garnered more than 1.19 million views on YouTube. We also collaborated with partners such as the Ministry of Manpower and Town Councils to educate the public on gas safety issues. Since July 2015, we have participated in 13 such events. IT’S IN YOUR HANDS In September 2015, we launched a Hand Safety Campaign to promote safe practices in hand-related operations, and prevent hand and finger injuries among workers. 51 PROMOTING A CULTURE OF SAFETY The introduction of the Motorcycle Helmet Camera has helped SP Services achieve zero controllable traffic accidents for FY15/16. We conducted workshops for contractors to share hand safety statistics and incidents from the previous year. We also discussed the root causes of such injuries and control measures that could be taken. Other campaign activities included conducting risk assessments, reviewing safe work procedures and participating in SP’s in-house training on hand safety. As of March 2016, some 125 contractors’ supervisors and safety coordinators had undergone the train-the-trainer session, and more than 2,100 workers had been through hand safety briefings. Within six months of the campaign’s launch, we saw a 63 per cent improvement in our LTIFR for hand-related injuries. ACTIVITY BASED SAFETY IMPROVEMENT SYSTEM (ABSIS) In March 2015, the Cable Tunnel team from Special Projects, SP PowerGrid, introduced the Activity Based Safety Improvement System (ABSIS), a systematic approach to ensuring the safety of our workers as they carry out critical tunnel construction operations. Throughout the year, the team captured video footage as workers conducted tunnelling activities, focussing on one specific activity each week. The 52 videos are used to educate workers on safe work procedures, enhancing their safety awareness and vigilance. This form of audio visual communication cuts across the various languages our workers speak and provides them with essential information to stay safe. The initiative has been well received by contractors and project consultants. DRIVING HOME THE SAFETY MESSAGE Our goal of zero safety accident means ensuring that our field staff are aware of the hazards that might exist in any given situation, and are well-equipped to minimise the risk of accidents. We introduced the SP Services Motorcycle Helmet Camera in May 2015 for all field 52 staff to help us evaluate their safety awareness of riding behaviour. Using the footage collected, we were able to identify gaps in riding safety and establish appropriate safety measures while raising safety awareness among our riders. Since its launch, SP Services has achieved zero controllable traffic accident for FY15/16. CUSTOMISED SAFETY EFFORTS The Singapore Institute of Power and Gas conducts safety training courses for SP’s contractors. The courses help them understand the importance of workplace safety and health, and enable them to apply safe practices at the worksite. The courses are customised, specifically for cable tunnel operations, building construction and for SPPG’s road works and installations. They are conducted in English as well as in Tamil, Bengali and Mandarin. In FY15/16, there were 6,500 contractors who underwent safety training at SIPG. BREAKING NEW GROUND FOR SAFETY The Cable Tunnel team from Special Projects, SP PowerGrid, received the Gold Award for Health and Safety 2016 from the Royal Society for Prevention of Accidents (RoSPA). The UK-based company has a more than 100- year history of promoting health and safety around the world. This is an endorsement of the team’s strategic initiatives, the support of management and our collective passion for raising safety standards in the tunneling industry. The video-based ABSIS system educates workers on safe work procedures, enhancing their safety awareness and vigilance.

From left, in blue SP polo Thor Wen Lei Senior Engineer, Network Development, Electricity Operations Gavin Ong Hongjie Senior Engineer, Network Management, Electricity Operations Tiong Heng Liong Assistant Director, Strategic Development POWERING A BETTER WORLD CELEBRATING SG50 n 2015, we celebrated I Singapore’s 50th birthday and SP’s 20th anniversary with a series of unprecedented initiatives. To the nation, we presented a Gift of Power, setting up free mobile device charging stations at 200 locations islandwide. Through Love from the Stars, a charity gala dinner and concert featuring international artistes like Jackie Chan, we helped raise close to S$6.4 million for six charities. These initiatives were among the “20 Good Deeds” of community service which we had committed to undertake to mark SP’s 20th anniversary. Our staff volunteers, also known as SP Heart Workers, initially set a target of 6,000 volunteer hours to accomplish 20 Good Deeds. They far exceeded this target, putting in almost 9,000 hours to perform 30 Good Deeds. Our community service initiatives benefitted low-income families, children with special needs, and the needy elderly. To help the public save energy and contribute to a sustainable Singapore, SP also initiated programmes to promote energy efficiency and the use of renewable energy. We celebrated Singapore’s 50th birthday by presenting the nation with a Gift of Power in July 2015 – 200 mobile device charging stations in high traffic locations across the city-state. Our aim is to help Singaporeans stay connected on the go, and our gift reflected our commitment to always be there for Singapore. The charging stations can be found at hospitals, polyclinics, universities, polytechnics, supermarkets and libraries, among other places. Besides giving mobil

SP Energy HubAnnual ReportReliabilitySustainabilityInnovation Mobile Generators: Powering Continuity RELIABILITY Mohamed Nasir bin Mohamed Ismail, Technical Officer, Electricity Operations (center) together with Ismet Imran bin Chuma'ing, Senior Technician, Electricity Operations (left) and Mohammad Najib bin Jalil, Technical Officer, Electricity Operations (right) from SP Group's Mobile Generator Unit. When an electrical glitch hit Kian Teck Avenue in Jurong last month, a team from SP Group’s Mobile Generator Unit was charged and ready to roll. In minutes, a mobile generator mounted on a 30-ft trailer left a facility in Pasir Panjang for the site of the incident. The generator carried some 2,000 litres of diesel, enough to power up a housing estate for around eight hours, and up to 40 metres of cable to hook up to a low-voltage (LV) board, which distributes electricity. “We need to always be prepared to provide temporary power,” says Mr Mohamed Nasir bin Mohamed Ismail, 42, a technical officer who is part of the unit. Readiness is key for the Mobile Generator Unit. This begins at 7.30am with a daily “warm up”, conducted by the 10 men on the morning shift. During the one-hour ritual, all the operational mobile generators – the larger ones mounted on fourteen 30-ft trailers, and the smaller ones on seven 20-ft lorries – are started and tested to ensure they are ready to be deployed. The team members also conduct cable insulation tests and checks on their toolboxes and personal protection gear. This enables them to act swiftly and safely, in the event of an electricity disruption. The men, who work on three shifts round the clock, are deployed by SP Group’s Electricity Service Centre in teams of three – a leader, an assistant, and a driver. Mr Nasir, the leader of his team, has been with SP for 21 years, joining right after he completed his National Service in 1998. He studied mechanical engineering at the ITE and plays the role of synchroniser, ensuring that the voltage and frequency of the mobile generator matches that of the grid network. Mr Nasir, who has both a Class 4 and Class 5 driving license, doubles up as a driver, and says navigating these massive vehicles is an exercise that requires both practice and courage. The trailer-mounted mobile generators cannot travel through tunnels, including those on expressways like the MCE, CTE or KPE. The 60km/h speed limit also keeps them in the slowest lanes most of the time. The trailer-mounted generators are part of a fleet of 22 vehicles of different sizes and capacities used for power restoration. “You need to know the quickest alternative route around traffic or restrictions. Outage in Ang Mo Kio and leaving from Pasir Panjang? Alexandra, Farrer, Adam, Braddell, then join the CTE after the tunnel,” Mr Nasir rattles off. The narrow roads in some estates and parked vehicles can also pose problems for the 13 metres by 2.6 metres by 4.3 metres trailers, and it is up to the two men with the driver to recce for a spot to hunker down – which must also be close enough to an electrical room to hook up. While Singapore enjoys one of the lowest occurrences of outages in the world, it is gratifying to be a part of a team that helps “get the lights back on" if supply is disrupted, Mr Nasir says. “We are usually greeted by frustrated faces when we arrive, so seeing them happy again makes us very happy,” he quipped. — 1 May 2019 TAGS PEOPLE OF SPRELIABILITY YOU MIGHT BE INTERESTED TO READ Engineer, 27, shares how she is undaunted by male-dominated energy industry & climbs the ranks Lighting the way: Following in his father’s footsteps to keep S’pore’s power grid running 24/7 How this technical officer and robot SPock hunt hazards to protect Singapore’s power tunnels

B6 HOME FRIDAY, NOVEMBER 22, 2013 FRIDAY, NOVEMBER 22, 2013 HOME B7 Like arteries and veins that keep the body alive with a constant flow of blood, close to 26,000km of cables, more than 3,240km of gas pipelines and a 3,000-strong team of people work around the clock to keep Singapore’s lights on and air cool. Arti Mulchand speaks to the unsung heroes. POWER TRIP Lighting up Marina Bay Getting power to the people IN 2004, when Mr Peter Leong oversaw the engineering division at Premas International, which provides property management services, Singapore was hit by one of its worst blackouts in history. Piped gas supply from Indonesia to Singapore’s power stations was disrupted by a technical fault and most turbines were unable to switch to the backup source of fuel. It caused a two-hour outage affecting more than 300,000 homes. In one home in Jurong, a man had a heart attack and needed to get to a hospital. The lifts did not work. At the time, Premas managed the Jurong Town Council, to which Mr Leong provided engineering support. “I had to send our contractor up to carry him down. I saw how the residents were affected. Failure can be very serious and I know how important continuity is. I remember that even now,” recalled the 57-year-old, who joined Singapore Power (SP) PowerGrid as general manager about five years ago. That image remains with him, and has served as a constant reminder in his current role as managing director of SP PowerGrid – he has to ensure “the lights are always on” for the company’s 1.4 million customers. “Singapore is like a copper mine. There is 26,000km of copper underground because everything needs power. Just like blood needs to flow to every part of the body, electricity needs to flow to every corner of Singapore. And like the human heart, we cannot afford to fail, so we do everything we can and put every effort into ensuring nothing goes wrong.” The three main areas Singapore Power covers are: planning and strategy, that is, planning ahead for energy needs; network development, that is, building the transmission and distribution network; and network management, that is, operating and maintaining network equipment. “The team works 24/7 to ensure the health of the system. We A SERIES BROUGHT TO YOU BY Building a more resilient grid THE power grid of the future could include a large number of distributed renewable generation sources such as solar photovoltaics, energy storage facilities and energy management systems. It is also expected to be flexible and scalable, such that fluctuations in energy demand or supply will not affect the grid’s stability and reliability. A team from the National University of Singapore, headed by Associate Professor Dipti Srinivasan, is working with SP PowerGrid to look into “dynamic optimisation and energy management for smart grids”. It hopes to develop a set of computational tools that will, among other things, automatically diagnose faults so outages can be handled quickly. respond immediately to any system distress,” Mr Leong said. Temperatures of transformers are taken, insulating oil is checked, and other parameters are continuously measured – whether online or off – to ensure that Mr Peter Leong, 57, managing director of SP PowerGrid, says that energy demand in Singapore has increased dramatically between the pre-war period and now. PHOTO: LIM YAOHUI FOR THE STRAITS TIMES the power paramedics can be sent in for swift and often pre-emptive responses. Exercises are conducted for everything from network management to billing, so that if anything goes wrong, everyone knows what to do. In the last 20 years, Singapore has achieved one of the most reliable grids in the world – the average amount of outage time has gone from 27.44 minutes per person a year two decades ago, to less than half a minute now. But just like Singapore has evolved, so must the power superhighways. Mr Leong says that energy demand has increased dramatically between the pre-war period and now. Power is pumped through some 26,000km of cables to more than 10,000 transmission and distribution substations that convert electricity into the necessary voltages for various uses. “As power demand grows, it becomes more efficient to push through power with higher-voltage cables. It is not unlike Singapore’s highways. Where two lanes used to do the job, we now have the Marina Coastal Expressway, which is 10 lanes wide. As energy intensity grows, we need a bigger highway,” said Mr Leong. The North-South and East-West Electricity Cable Tunnel Project is part of that expansion. Its two 60m-deep tunnels will span 35km way below the MRT and even the sewerage system and, when completed in 2018, will reinforce Singapore’s power grid as one of the most reliable in the world, said Mr Leong. The company has been looking into how new technologies and energy sources, such as solar photovoltaic power, could impact the grid. As Mr Leong listed some of the major infrastructural projects in store for the nation – Changi Airport’s Terminal 5, Project Jewel at Changi Airport, the redevelopment of the southern waterfront and new container ports at Tuas – his eyes lighted up. “We have to plan now for tomorrow,” he said with a smile. Mr Leong, who studied electrical engineering at RMIT University in Australia and did his master’s at the National University of Singapore, began his career at the then-Singapore Institute of Standards and Industrial Research, which eventually merged with the National Productivity Board to become Spring Singapore. There, he spent 18 years with safety on his mind, operating the nation’s test lab for equipment and accessories that connected to the electricity network, then regulated by PUB, the national water agency. He did product testing and also participated in investigations into electrical deaths. When he moved on to Premas, he oversaw the maintenance and operation of equipment such as chillers, lifts and switchboards in commercial buildings and techno parks, and several town councils. But it is at Singapore Power that he has found a “better sense of purpose”, he said. “I love being able to look at how to do things differently, and I can never say that my job is done. This is a journey without a finish line.” Mr Thiam Chiong Seng helped build the Marina South substation, which powers Marina Bay Sands and Gardens by the Bay. ST PHOTO: NEO XIAOBIN Senior engineer Chu Xiao En (left) at SP PowerGrid’s Emergency Operations Centre. PHOTO: LIM YAOHUI FOR THE STRAITS TIMES MORE THAN DRAWING LINES ASK senior engineer Chu Xiao En what the biggest misconception about her job is and she will tell you it is this: “People think that planners only draw lines.” The 27-year-old works in Singapore Power’s planning and strategy division, which plans for Singapore’s electrical infrastructural needs five, 10 and even 20 years down the road. They include the need for new substations, and the renewal or decommissioning of old ones. “While the end result of a plan and review might be a line connecting two substations, a lot of analysis goes into exploring every possible option and anticipating all kinds of contingencies,” she said. The 15-strong team she belongs to gathers input from customers along Singapore Power’s transmission and distribution grid, and looks at the growth and development plans for the country, said Ms Chu, who oversees network planning for Singapore’s western region. She covers areas WHEN Mr Thiam Chiong Seng drives along the East Coast Parkway and past the Marina Bay area, it is rarely without a smile on his face. The 47-year-old engineer is the director of network development at Singapore Power (SP), where he has worked for 16 years doing high-voltage equipment installations, including at the Marina South substation. That means keeping the lights on in iconic buildings that include Marina Bay Sands, the Marina Bay Financial Centre and Gardens by the Bay. “With Marina Bay, I know that we are literally powering it. You can see and feel the impact,” he said. “That’s why it’s very exciting being in the energy business. You’re not dealing with tiny electronics. What we build is so huge so you feel a real sense of satisfaction when you see a job completed.” SP’s network development engineers develop and build the infrastructure that ensures continuous and reliable power supply to households, as well as industrial and commercial buildings. This includes forging the fit between network demand and supply, conducting simulations and doing tests and checks on equipment before it is used. “We don’t want a situation in such as Choa Chu Kang, Jurong, Woodlands and Ayer Rajah. Part of the job includes carrying out simulation studies, planning cable routes and substation sites, and figuring out how to get the best possible network at the lowest cost. Each year, her department submits an updated 10-year plan to the Energy Market Authority (EMA), which takes into account developments and changes. “The EMA works top down and we work bottom up to forecast the national energy demand,” she explained, adding that based on the latest estimates, energy demand in Singapore could grow between 2.2 per cent and 3.7 per cent each year between this year and 2023. It is that kind of work that appeals to the self-confessed applied mathematics and physics fan. “I have always been a rational and logical person so that’s what attracted me to engineering. I like that one plus one will always be which we turn the equipment on and you suddenly see ‘fireworks’. We have our biggest fireworks display on National Day and we’d like to keep it that way,” Mr Thiam said with a laugh. What makes the Marina South substation unique is that it is Singapore’s first substation that can receive bulk energy transmissions at 230 kilovolts (kV) from the power generation companies and then convert it to 22kV, which is the voltage at which some consumers can use it. Usually, power has to be converted to 66kV before being reconverted to 22kV or lower voltages, but new equipment allows it to bypass that intermediate stage. That means saving on space and equipment cost. The current capacity of the substation is 300 megavolt amperes (MVA) – meaning it can power up an area up to twice the size of Ang Mo Kio Town. “But we have also future-proofed it so it can deal with the area’s expansion,” he explained, adding that the substation is capable of servicing the area’s needs for at least the next decade. The substation also has three sets of 230kV cables to create a situation of “double redundancy”, so even if one set is knocked out, the other two function as two,” said the Singapore Power scholar who did her degree in electrical engineering at Imperial College and her master’s at Stanford University. She joined Singapore Power in 2009. The job has multiple challenges. For instance, her department is looking into the renewal of a lot of electrical infrastructure that was created in the 1980s, but there are limitations on what can be done. “Most of the renewals are done in mature estates, so you’re working with a live network. You need to have a step-by-step contingency plan for anything that might go wrong,” she explained. The four years that Ms Chu has been at Singapore Power have included a three-month stint at the company’s Melbourne-based subsidiary Jemena, and eight months in Network Management, a department tasked with ensuring that power supply to customers does not get disrupted. She worked on, for instance, the diversion of power cables that Planning for the next generation back-up, keeping the lights on. Mr Thiam got involved in the Marina South project in 2000, when his team helped outline the technical requirements for transmitting power through South-east Asia’s first Common Services Tunnel, which was being built by the Urban Redevelopment Authority at the time. Those tunnels, which sit between 2.5m and 20m underground, deliver everything from electricity to chilled water and telecommunication cables. “The Government realised the CBD (Central Business District) had to be expanded, and we were able to support them in the development,” said Mr Thiam, who oversees a department of 18, including six engineers. Mr Thiam, who studied electrical and electronic engineering at Nanyang Technological University, started out in an industrial air-conditioning company before moving to an SP subcontractor doing maintenance work on 230kV transformers. He was so impressed with Singapore Power that he ended up applying for a job. He has not looked back since. What he is especially proud of is that other countries look to Singapore for the types and technical specifications of equipment used and even quality control processes. But communicating this information can be harder than one can imagine. “In China, it would be rude to speak English, but try finding the Chinese word for cross-linked polyethylene (XLPE) or polypropylene laminated paper (PPLP). Chinese is not our native language for technical terms,” he exclaimed with a laugh, referring to the types of insulation materials used in cables. His overseas exposure has also been eye-opening, not least because of the much higher tolerance level other countries have for disruptive electrical and road works. “In China and India, they understand that electrical cabling is for the good of the country. Here? We have to work at night or traffic would be obstructed, and we can work only a limited number of hours at night because residents complain about the noise,” he said, shaking his head. During the Marina South substation project, for instance, one 900m stretch of road between Anson Road and Cecil Street took almost two years to complete because work could be done only between 8pm and 4am and the noisier work had to be finished by 10pm. “In other countries, they would just block off the road and finish it up in just months.” had been laid under Upper Bukit Timah Road to make way for the construction of Downtown Line 2, which is due to be completed in 2016. “I never realised how much went into the planning of an MRT line. There is a lot of preparatory work that has to be done alongside other utility providers. I am now a lot more tolerant of road works,” said Ms Chu, whose husband is also an electrical engineer in the power sector. The time spent in Network Management made her an unlikely sympathiser when a fire broke out at SingTel’s Bukit Panjang facility in October, disrupting a range of services across the island, including her pay TV services at home. She was part of a team that, following a fault that tripped a circuit in Woodlands in 2009, had to walk along roads that had cables under them, armed with cable fault detectors and special headphones to identity the problem segment. It was about a day and a half before the segment was isolated, and only then could contractors proceed to dig up the road, find the fault and fix it. She said: “While the public was asking why there were no back-ups during the SingTel incident, I felt appreciative of what they were trying to do to restore the network. When these things happen, you are really trying your best to get things back up. I understand how challenging that can be.” And while being a planner also means gratification is much delayed, since most of the projects she has had a hand in planning have yet to become a reality, it makes the job no less fulfilling. “We get to be involved first-hand in nation-building. And I appreciate that the good performance of our network today is the result of the work of some of my mentors and the planners that have come before me. “Now, we’re planning for the next generation.” ENSURING SMOOTH OPERATIONS All fired up about keeping businesses cool SINGAPORE District Cooling’s (SDC) senior engineering officer for safety Ariff Shah Mohd proudly declares that in his seven years with the plant, there has not been a single serious accident. The plant, which spans 19,000 sq m, supplies the chilled water that keeps many buildings in the Marina Bay financial district cool. Among his responsibilities: to ensure compliance with safety measures and equipment, and make sure that all the permits for machinery are in order. “I have to cultivate a culture of safety among the staff as well as our contractors, and ensure that the plant has reliability and efficiency and operates safely. It can be tricky, and you have to be alert,” said the 39-year-old, who holds a position more often held by someone who is trained in engineering. Mr Ariff, an Institute of Technical Education graduate who studied mechanical and electrical drafting and design, toyed with the idea of becoming a policeman before ending up in IT support. Eventually, he learnt the ropes as an operations technician at a petrochemical plant on Jurong Island. That led him to a similar position at the SDC plant, which began operations in 2006. SDC is a joint venture between Singapore Power and Dalkia. After four years, he was given the opportunity to pursue a oneyear specialist diploma in workplace safety and health at Singapore Polytechnic in 2009, after which he was promoted to engineering officer for safety and projects. This year, he became senior engineering officer for safety. Today, he oversees all of the plant’s safety matters, including safety precautions that are in place, risk assessment, safety compliance and training. He is also the secretary of the plant’s 10-man safety committee, which meets once a month. This father of two is so passionate about safety that, this week, his team held its first SDC Safety Day. Some 70 spouses and children of SDC’s staff had a first-hand look at how the plant works and a lesson on why safety matters. Safety Day will now be an annual affair. Similarly, Mr Wong Toon Soon, the operations manager of Keppel District Heating and Cooling Systems (DHCS), started out in construction, doing electrical installations. Mr Wong, who is now 51 and also a father of two, became an electrical foreman after completing a full-time Industrial Technician Certificate course at Singapore Technical Institute. Mr Wong, who received his diploma in electrical engineering from Singapore Polytechnic in Neither Keppel DHCS operations manager Wong Toon Soon (above) nor Singapore District Cooling senior engineering officer for safety Ariff Shah Mohd (right) started their careers in the district cooling field, but both men now power vital aspects of their plants which provide cooling services in various parts of Singapore. ST PHOTOS: CAROLINE CHIA, NEO XIAOBIN 1991, was also keenly interested in energy efficiency, which was a buzzword in the late 1990s. He was introduced to the brand-new sector of district cooling when his company became involved in the construction of the Keppel DHCS plant in Changi Business Park, Singapore’s first district cooling system, in 1998. When completed, it would provide cooling services to businesses in the area, including commercial, banking, biomedical and wafer fabrication customers. Fascinated, he applied for a position as senior control engineer in 2003. He said: “During the construction phase, I realised they were using the latest energy-efficient technologies and I was excited at the prospect of learning more. This was my opportunity.” Just three years later, he was promoted to operations manager of all three of Keppel’s DHCS facilities. Keppel is the only other provider of district cooling services here, and services 18 customers in Changi Business Park and 18 at Biopolis. It also provides district cooling at Woodlands Wafer Fab Park. Mr Wong, who also has specialist diplomas in energy efficiency management and security networking, ensures that the plants run smoothly, and works closely with Keppel’s customers to help them maximise their efficiency gains. He was involved in setting up a DHCS plant in the Sino-Singapore Tianjin Eco-City in 2010, where he oversaw everything from its construction all the way to the time the chilled water started pumping. It has been up and running since August. At the moment, Mr Wong is planning to refresh the 13-year-old DHCS plant in Changi – Keppel’s oldest DHCS facility – with new and more efficient chiller equipment planned for next year. Keppel, which is looking into new sites for DHCS facilities, most recently secured the contract to provide district cooling to Mediapolis from the second quarter of 2015. Mr Wong is most encouraged by the growing footprint of district cooling, especially since building owners and tenants have much to benefit from this, both in terms of lower investment costs and energy savings. In the longer term, it also means having a smaller carbon footprint. “It is better for business, and better for the planet as well,” he concluded. CHILLING UNDERGROUND The world’s largest district cooling plant ALL the action at what is arguably the world’s largest district cooling plant by capacity is well hidden from public view. The plant is located five floors – about 25m – underground. The only evidence of the plant’s existence is a cleverly concealed cooling tower, which pops up above the ground facing Marina Bay Sands’ hotel building. A curtain of metal plates that allow exhaust heat to escape the tower shimmers in the sunlight, and a strategically placed water feature masks the sound of the water that flows from it. Even access to the plant, which produces 600 tonnes of chilled water per hour, is like a scene out of Alice in Wonderland – there is no signage, only a small door located at the end of the Double Helix Bridge. Stairs and a lift transport the plant’s 52 employees deeper underground. Chilled water is one of several utilities continuously pumped through a network of common services tunnels to 14 customers in the area, including Marina Bay Sands, the Marina Bay Financial Centre and One Raffles Quay. District cooling is an energy-efficient and cost-effective method to provide buildings in the area with an optimal indoor climate. In the case of Singapore District Cooling, chilled water is produced by production plants and distributed by water pipes contained within the common services tunnels. Specially designed units within each building draw on the cooling properties of the water to, for instance, lower the temperature of the air passing through the air-conditioning system. There are three interconnected plants in Marina Bay spanning a total of about 19,000 sq m – the other two plants are at One Raffles Quay and One Marina Boulevard – and there are plans to grow this to five plants, so more than eight million sq m can ultimately be serviced. The success of a cooling plant lies in being able to maintain the temperature of continuous water flow at under 6 deg C. At Singapore District Cooling, that standard is met 99.9999 per cent of the time. Using a district cooling facility – as opposed to having to build and install their own plant rooms and cooling towers – helps make businesses in the area about 30 per cent more energy-efficient. In temperate countries, similar networks can be used to supply heating, as is the case with Keppel’s District Heating and Cooling Systems plant at the Sino-Singapore Tianjin Eco-City in China. Keppel also has three district cooling plants. They are located in Changi Business Park, Biopolis and Woodlands. While it is more common in the United States and the Middle East, district cooling is catching on in Asia, said Singapore District Cooling managing director Jimmy Khoo, adding that the Marina South substation is a “true success story for Singapore”.

SP Energy HubAnnual ReportReliabilitySustainabilityInnovation SP partners EDF Group to develop subsea transmission cable RELIABILITY Stanley Huang (left), SP Group CEO, with Jean-Philippe Buisson, Senior Vice President of Asia at EDF International, at the MOU signing ceremony on 11 October 2021. SP Group signed a Memorandum of Understanding (MOU) with EDF Group (EDF) on 11 October 2021 to jointly develop a subsea transmission cable to support renewable energy import from Indonesia. The infrastructure aims to facilitate future electricity import from Indonesia, starting with a proposed 1,000MWp solar photovoltaic plant to be developed by a consortium of partners led by EDF Renewables, a subsidiary of EDF. As part of the MOU, SP and EDF will embark on commercial, regulatory and technical feasibility studies for the subsea cable, and explore opportunities to widen the interconnection to other neighbouring clean energy generation sources in Indonesia to improve economies of scale. When completed, the subsea transmission cable will be a key enabler for regional power system integration, ensuring scalable grid connection capacity from Indonesia. Group CEO Stanley Huang, said, “We are honoured to partner with EDF to support the import of green energy from Indonesia into Singapore. The subsea transmission cable will be an important part of the regional grid interconnection and allow us to better plan for future network requirements to maintain our reliability standard. We look forward to working closely with EDF on the feasibility studies.” Jean-Philippe Buisson, Senior Vice President, Asia, EDF International, said, “This partnership with SP Group is in line with EDF Group’s ambitions of promoting cross border interconnection globally which supports the flow of renewable energy. EDF looks forward to mobilising its comprehensive expertise, both technically and commercially, to support the implementation of this common subsea transmission cable between Singapore and Indonesia with our best practices and past experiences.
