SP Energy HubAnnual ReportReliabilitySustainabilityInnovation Electricity’s First Responders RELIABILITY SP Group’s Principal Engineer Jerome Choong is one of the first at the scene should an electricity disruption happen. Five-year-old Jovan thinks his father Jerome Choong, an SP Group Principal Engineer, is a cross between an electrician and a magician. “He thinks that when people have no electricity, they call me, and I make it appear,” laughs the 35-year-old, who takes care of the electricity distribution network in the north zone, which spans the area stretching from Boon Lay to Punggol. “Jovan used to get annoyed when I left abruptly during family gatherings. Now, he is proud of what I do,” says Jerome who also has a two-year-old son. Principal Engineer Jerome Choong (right) and son Jovan Jerome has been with SP for seven years and leads a unit of 30. He is one of the first on site when an outage happens. His priority is to work with his unit to quickly and safely get supply back up. While prevention is key and every effort is made to keep trouble at bay, it is important to be prepared for the unexpected. It helps the team spring into action without delay should something happen. His car boot is testimony to his commitment – half holds a stroller for his two-year-old, and the other half, the tools he needs, from cable insulation testing equipment to multi-meters. His iPad stores documents, schematic drawings and operations manuals. His network of fellow engineers is a Whatsapp message away. Always on the alert, Jerome forms his recovery plan as he drives to the site where an incident has occurred, helped by information on the location, number of customers affected, and the substations and breakers he should zoom in on. This is provided by the Electricity Service Centre and Distribution Control Centre, which he works closely with. Principal Engineer Jerome Choong checking on switchgears in a substation. For every incident, he and his colleagues investigate what went down, isolate and test the equipment, and start on repairs or replacements. “We explore every what-if scenario,” Jerome says, “and have back-ups to the back-up plans.” While the control centre can remotely resolve some issues, manual intervention by Jerome’s team is sometimes required, and checks are always done before supply sources are switched to ensure safety. Replacement parts are also tested before being connected and energised. Only then is the power transferred back on to customers. Work does not end when an issue is resolved, and even a late-night activation often sees him back on duty the next morning. In the day, Jerome oversees the maintenance of the switchgears and transformers of the high-voltage network. He also regularly engages commercial and industrial customers with higher electricity consumption requirements. The job keeps him on his toes, he says, as does the need to evolve with his role. The rise of renewables, for one, has meant having to integrate non-traditional sources of electricity onto the grid. “I love solving problems, and we seldom encounter two situations that are exactly the same. We’re constantly learning, and re-learning. That’s what keeps the job interesting.” (From left) Principal Engineer Jerome Choong with Service Technicians Hasly Bin Hashim and Mohammad Iskandar bin Sapari attending to an incident at an affected substation.

FAQs – SP Group’s Electric Vehicle Charging Network How do I get access to EV charging on the SP Utilities app? Download the SP Utilities app on your compatible phone and follow these steps: 1. Tap on “Explore” within the bottom navigation bar 2. Access the EV Charging page by tapping on the EV Charging icon 3. Follow the onscreen instructions to begin charging Where can I find the charging stations in Singapore to charge my EV? The list of charging locations are available on the app. The list will be expanded progressively as SP Group grows the charging network in Singapore. Why does DC charging automatically stop before my battery is full? In order to prolong battery life, some EVs are designed to automatically stop or slow down DC charging after their batteries have reached around 85-95% charge. This threshold is not imposed by the SP charging station. For more details, please consult your EV manufacturer. Can I continue parking in the EV charging lot after my charging session? As good etiquette within the EV community, please move your EV within 30 minutes from the end of your charging session. Are your outdoor chargers safe to use during rain, lightning and adverse weather conditions? Our charging stations comply with all relevant safety standards. However, in the event of heavy rain and/or lightning, please refrain from using charging points located in unsheltered areas. How do power ratings affect my charging time? The power rating of a charging point is measured in kilowatts (kW) and is the maximum rate at which a charging point can transfer electricity to an EV's battery. Actual charging time depends on the EV’s design (e.g. battery size, capacity of on-board charger, compatibility with AC and/or DC chargers). DC charging (also known as fast charging) occurs at a higher power rating compared to AC charging. This allows EV batteries to be charged faster. To use DC charging, your EV must be compatible. To check if your EV can support DC charging, please consult your EV manufacturer. How are my fees calculated? Fees will be calculated on a per kilowatt-hour (kWh) basis. The kWh is a unit of measurement for electricity consumption. For example, a EV charging at a rate of 43kW for one hour will consume 43kWh. Your fees are equal to the electricity consumed during your charging session (kWh) multiplied by the Applicable Rate ($/kWh). Will the charging points be able to accommodate all types of electric vehicles? As long as your electric vehicle adheres to Singapore’s national standards, which is Type 2 AC and Combo 2 DC, your vehicle will be able to charge on our network. Can I charge on the SP network if I am driving a plug-in hybrid EV (“PHEV”)? Yes, you can. However, some PHEVs are not built to utilize our faster charging stations. Please check with your car manufacturer for details. Meanwhile, we are working hard to install 22kW rated charging stations, which are more suitable for PHEVs. If I am interested to have charging points installed in my premises for public use, how do I get in touch? We welcome interested parties to contact us at emobility@spgroup.com.sg. Who can I contact for more help with regard to electric vehicle charging? Besides emailing us at emobility@spgroup.com.sg, you can also contact us at 6916 7799 during our operational hours.

Cents/kWh MEDIA RELEASE ELECTRICITY TARIFF REVISION FOR THE PERIOD 1 OCTOBER TO 31 DECEMBER 2020 Singapore, 30 September 2020 – For the period from 1 October to 31 December 2020, electricity tariff (before 7% GST) will increase by an average of 1.83 cents per kWh compared with the previous quarter. The revised tariff and that of the preceding quarter are the lowest in the last three years. The increase this quarter is due to higher energy costs, which forms a major component of the electricity tariff and is paid to power generation companies. The remaining components of the tariff, consisting of network costs and market support services fees to SP Group and Market Administration and Power System Operation Fee to Energy Market Company and Power System Operator, remain unchanged (Appendix 1: Breakdown of Electricity Tariff). For households, the electricity tariff (before 7% GST) will increase from 19.60 to 21.43 cents per kWh for 1 October to 31 December 2020. The average monthly electricity bill for families living in fourroom HDB flats will increase by $7.01 (before 7% GST) (Appendix 3: Average monthly electricity bills of domestic customers). 30.00 Quarterly Household Electricity Tariff* 25.00 20.00 23.85 22.79 24.22 23.43 24.24 23.02 19.60 21.43 15.00 10.00 5.00 0.00 Jan - Mar 19 Apr - Jun 19 Jul - Sep 19 Oct - Dec 19 Jan - Mar 20 Apr - Jun 20 Jul - Sep 20 Oct - Dec 20 *before 7% GST The electricity tariffs are reviewed quarterly based on guidelines set by the Energy Market Authority (EMA), the electricity industry regulator. The tariffs shown in Appendix 2 have been approved by the EMA. Issued by: SP Group 2 Kallang Sector Singapore 349277 www.spgroup.com.sg Appendix 1 BREAKDOWN OF ELECTRICITY TARIFF 1. The electricity tariff consists of the following four components: a) Energy costs (paid to the generation companies): This component is adjusted quarterly to reflect changes in the cost of fuel and power generation. The fuel cost is the cost of imported natural gas, which is tied to oil prices by commercial contracts. The cost of power generation covers mainly the costs of operating the power stations, such as the manpower and maintenance costs, as well as the capital cost of the stations. b) Network costs (paid to SP PowerAssets): This fee is reviewed annually.

Media Release Singapore Power Charity Golf Raised $363,800 For Needy Elderly $7 million channelled to Home Help Service through SP Heartware Fund Singapore, 27 August 2013 - As if being encumbered with the triple chronic dread disease of hypertension, hypolipidemia (high cholesterol) and diabetes is not enough, Madam Chin Fee Fee also suffers from spinal stenosis – a narrowing of the open spaces within her spine, which renders her almost immobile. Yet the 78-year-old, who lives alone, remains upbeat, thanks to a group of volunteers who deliver hot meals to her home everyday and ferry her to and from her home to her medical appointments. Madam Chin is a beneficiary of Dorcas Home Care Service - supported by the Singapore Power (SP) Heartware Fund. The Fund is dedicated to supporting Community Chest’s Home Help Service programmes, which help the needy elderly in our community age with hope and dignity by delivering critical care services to them in their homes. The SP Heartware Fund received a boost when Singapore Power, together with its business associates, raised more than $363,800 in support of the Singapore Power Charity Golf 2013 which will be held at the Singapore Island Country Club on Friday, 30 August 2013. The SP Charity Golf is Singapore Power’s key community outreach event for the year. All donations from the event are channelled to the SP Heartware Fund. Since the launch of the SP Heartware Fund in October 2005, Singapore Power has raised more than $7 million for Community Chest in support of seven Home Help Service programmes. Needy seniors who live alone and are unable to cater to their basic needs are the main beneficiaries of the programme which include daily meal deliveries, assistance with personal hygiene and laundry, and transport to medical appointments. The needy elderly remain the focus of Singapore Power’s community outreach endeavours in view of Singapore’s ageing demography. By 2030, it is projected that there will be 117,000 seniors who are semi-ambulant or non-ambulant, i.e. more than 2.5 times that of today1. A culture of giving and sharing is taking root at Singapore Power. Beyond collaborating with its partners to raise funds through events like the Charity Golf, Singapore Power also encourages its staff to do their part in reaching out to the community through various community outreach initiatives. One of these is the recently launched Nature Cares programme where Singapore Power staff took time off from work and spent quality time bonding with the residents of St John’s Home for Elderly Persons and students of Cedar Primary School, over nature-related activities such as making bottled gardens and visits to parks. These activities give much boost to the morale and emotional well-being of the elderly beneficiaries. Staff have also been involved in other charitable initiatives such as the JP Morgan Run, in aid of Operation Smile, which provides free surgeries to repair facial deformities for children around the globe. Said Mr Wong Kim Yin, Group Chief Executive Officer, Singapore Power: "The needy elderly have made valuable contributions to society. It is extremely heartening when we at Singapore Power and our business partners are united in the cause of giving our pioneer generation a lift for their basic daily activities, to provide medical assistance and to support their desire to live independently and with dignity." _________________________________ 1COS speech by Minister Gan Kim Yong on Ministerial Committee on Ageing Initiatives (7 Mar 12)   About the SP Heartware Fund The SP Heartware Fund was launched in October 2005 to help the needy elderly in the community lead better lives.

Reg No : 199406577N                  www.singaporepower.com.sg Annex 1 Madam Chin Fee Fee Age : 78 Beneficiary of Dorcas Home Help Service, under the care of Community Chest Divorced with one son who has lost contact with her for the past six years, Madam Chin lives alone in a two-room rental flat in Commonwealth Crescent. Madam Chin suffers from hypertension, hyperlipidemia (high cholesterol) and diabetes. She also has spinal stenosis – a narrowing of the open spaces within her spine, which puts pressure on her spinal cord and the nerves that travel through the spine. The condition causes her constant pain, numbness and muscle weakness. Her condition renders her home-bound most of the time, moving around her flat very slowly with the help of a walking aide. On the rare occasion when her health permits, she would travel on a wheelchair around her neighbourhood. Dorcas Home Care Service – supported by the SP Heartware Fund - has been providing Madam Chin with much needed assistance. Staff from Dorcas Home deliver hot meals to Madam Chin every day, and also provide transportation and escort her for medical appointments at the nearby Queenstown policlinic. In addition, staff and volunteers who help with the meal delivery make it a point to observe how Madam Chin is coping with the business of daily living and intervene where necessary. When Madam Chin’s mobility becomes increasingly laboured, volunteers would promptly inform staff of Dorcas Home who will then expedite a visit to the polyclinic. Said Madam Chin: “I am grateful for the kindness of volunteers who have helped me so much in my time of need.”
