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.

SP Energy HubAnnual ReportReliabilitySustainabilityInnovation Shaping the evolution of electricity meters in the past 25 years RELIABILITY Vice President of SP Services’ Metering Branch Razali Bin Mohd. “If my coral dies, you pay”, is a customer’s comment that 51-year-old Razali Bin Mohd recalls in an unforgettable experience during his earlier days as an engineer. His team was carrying out electricity meter replacement works then. In this unique situation, when the customer was informed that the power supply will be temporarily disrupted during the replacement, she requested for a mobile electrical generator to keep her coral tanks maintained at four degrees Celsius during the servicing period. Handling a multitude of customer requests, is part and parcel of stakeholder management in Razali’s job at SP Group (SP). Over his 25 years with SP, the Vice President of SP Services’ Metering Branch has seen the evolution of analogue electricity meters manually read by meter readers to smart meters that can now be monitored remotely. As of May 2022, Razali and his team have deployed over 650,000 smart electricity meters islandwide. In the next few years, all 1.4 million residential households in Singapore will be equipped with smart meters. “I cherish this experience the most as we took great lengths to incept this idea and eventually see it come to fruition. As this project had a nation-wide impact, I remembered we went to the Parliament to present our plans to the Mayors, and convinced the relevant agencies to support our deployment plan.” Razali now has another ambitious task ahead of him. Besides rolling out smart electricity meters nationwide, his team also won the contract for Singapore’s first large-scale smart water meter programme for PUB in Apr 2021. Over the next 15 years, they will be developing the metering system, enhancing the wireless communications network, deploying, operating and maintaining over 300,000 smart water meters. “We faced intense competition against strong contenders and various challenges during the tender process. Our strong teamwork and expertise in smart electricity meter deployment has enabled us to secure this strategic partnership. The late-night calls with counterparts from different parts of the world were all worth it!” Interestingly, his career options after graduating as an electrical engineering graduate from Nanyang Technological University were between a cadet pilot at a leading airline and an engineer at SP. He received SP’s letter of offer on the day of his final round of interview for the cadet pilot position. “I just went with my gut feel and I am convinced now looking back, it was meant to be.” he recalled fondly.   Razali with his colleagues from the metering team at the old St James District Office in 2011. Back in the late 90s, Razali’s key responsibilities included working with contractors to install and maintain meters for residential and commercial customers, procure new meters, handle project tenders and manage customer feedback.  The implementation of smart electricity meters in Singapore has been the highlight of his career. Razali with colleagues from SP Services and SP Digital on an overseas trip to Itron’s office in San Francisco, to adopt best practices from the implementation of the US’ smart meter programme. Before the opening of Singapore’s electricity retail market in 2014, Razali and his team travelled to San Francisco and Melbourne to learn how these cities deployed smart meters successfully. “The study trip shortened our learning curve and prevented potential pitfalls.” SP is one of the first few utility companies in the world that has separated its communication network card from the meter. In other parts of the world, communication modules are integrated within the meters. Hence, if the communication part fails, the entire meter must be replaced. In Singapore, the decision was to adopt a “modular” structure for parts to be replaced separately if they are faulty. This will not only save cost, but also eliminate supply interruption and reduce inconvenience to the customers. CEO of SP Services Law Chin Ho (sixth from left) and Razali with the SP Services team that won the contract for Singapore’s first large-scale smart water meter programme for PUB in Apr 2021. Razali is thankful for all the growth opportunities at SP and is committed to continue rising to the challenges in the evolving energy industry. “I wake up every day looking forward to the next challenge at work. I am thankful for the wonderful team support. We are constantly innovating and finding solutions to problems. It gives me a huge sense of job satisfaction!” Volunteering trip with SP colleagues in Cambodia in 2015. In his free time, Razali enjoys travelling for nature walks, trekking, snorkelling, and exploring other types of land and sea activities. He also finds meaning in organising charity trips to children’s orphanages in Thailand, Cambodia and Indonesia and has even rallied his colleagues to join him in distributing essential items for these vulnerable communities. With borders reopening, Razali hopes to revive this initiative very soon!

SAFETY PERFORMANCE CRITERIA Introduction 1. With effect from 1 April 2022, all tenders called by Singapore Power Limited and its Singapore incorporated subsidiaries (SP Group) will include a tender evaluation criteria that takes into account the participating tenderer’s safety performance in their contracts with SP Group. With effect from 1 April 2023, this criteria is extended to subcontractors with LTI. 2. This is in line with SP Group’s core value that safety is our highest priority and all our suppliers and contractors must continuously adopt good safety practices and prevent accidents from occurring. Tender Evaluation Criteria 3. All open and closed tenders published on or after 1 April 2022 by SP Group shall include the new Safety Performance criteria as part of its tender evaluation criteria. 4. The Safety Performance criteria shall be a 1 st level evaluation criteria together with Price and/or Quality and shall be of a overall weightage of not less than 10% of the total evaluation score. 5. For tenders that is evaluated based solely on lowest compliant priced tender with no requirement to assess quality (e.g supply of standard items such as HP toner cartridges), the following evaluation method shall apply: Total Evaluation Score (100%) = Safety Performance (10%) + Price (90%) 6. For tenders that is evaluated based on Price and Quality factors, the following evaluation method shall apply: Total Evaluation Score (100%) = Safety Performance (10%) + Price (X%) + Quality (Y%) Where X + Y = 90% 7. For the avoidance of doubt, other safety related evaluation criteria such as the proposed safety measures to be taken for the tendered project or the tenderer’s past safety awards shall be accounted separately under the Quality score. Safety Performance 8. Safety Performance of tenderers shall be assessed by taking into account the occurrence of any Loss Time Injury (LTI) incidents in the past 2 years prior to tender closing date. In the event of the occurrence of any incidents that results in fatality or serious injury in the past 1 year prior to the tender closing date, the bid submitted by the tenderer may be rejected by SP Group. For the avoidance of doubt only incidents occurring on or after 1 April 2022 will be considered. 9. Loss Time Injury incidents for the purpose of this Safety Performance criteria refers to any incidents where: a. It is a work-related injury occurs which results in lost work time of one work day or more; b. The incident occurred while the tenderer was carrying out works under a contract with SP Group; and c. The incident occurred on or after 1 April 2022. 10. Any incidents that occur in the course of the Tenderer’s work in contracts with other parties are not accounted under this criteria’s scoring but may considered in the final decision for award.
