SP Group starts vehicle-to-grid technology trial � THU, JUL 08, 2021 - 9:24 PM | UPDATED THU, JUL 08, 2021 - 9:35 PM TAY PECK GEK � peckgek@sph.com.sg � @PeckGekBT Jimmy Khoo, chief executive of SP PowerGrid, with the V2G-capable Nissan LEAF and a V2G bi-directional charger that will be used in the Singapore trial. NATIONAL grid operator SP Group (SP) has started its trial of vehicle-to-grid (V2G) technology and has raised its investment in a V2G technology rm as Singapore progresses towards wider adoption of electric vehicles (EVs). The company aims to test the viability of tapping the energy stored in EVs in the trial to enhance the reliability of the grid, which will need to support more than 600,000 vehicles when Singapore phases out internal combustion engine vehicles by 2040, said SP in its media statement on Thursday. When charged, EVs store energy in their lithium-ion batteries, which serve as small energy storage systems that can transfer energy back to balance the power grid, such as when renewable energy sources such as solar power fluctuate due to weather conditions. If V2G technology is viable, owners of EVs can be paid for the use of their batteries when they are tapped to mitigate the intermittency problem in other energy sources. SP has stepped up its investment in the V2G technology rm The Mobility House (TMH), but did not provide the speci cs. SP only stated that TMH has a presence in Munich, Zurich and Belmont (in California) , and provides a non-proprietary software for integrating vehicle batteries into power grids using intelligent charging and storage solutions. SP is providing four V2G charging points at SP's premises for the trial, which will be completed in June 2022. V2G technology allows energy transfer between the batteries within an EV and the power grid, and so is more sophisticated than uni-directional charging of EVs.

16 June 2020 FACTSHEET Households’ Electricity Consumption During the Circuit-Breaker Period Singapore households’ electricity consumption typically increases from April through August. This is because the weather tends to be hotter in these months, and households use more electricity to power their fans or air-conditioners to stay cool. 2 During the Circuit Breaker (CB) period, most Singaporeans have been staying, working, or studying from home. This, coupled with the hotter weather, has led to higher electricity usage as well. For example, we saw an average increase of 22% in daily household electricity consumption in May 2020, compared to February 2020. How Households Are Billed During the Circuit-Breaker Period 3 Under normal circumstances, SP Group will send meter readers to visit households to record their electricity, water and gas consumption every alternate month. From 7 April to 1 June 2020, SP Group suspended physical meter reading services in line with the safe distancing measures to minimise the transmission of Covid-19. 4 For households who do not have advanced electricity meters and also did not submit their own meter readings, their April and May consumption were estimated based on previous months’ consumption data. This would result in an underestimation of their bills for these months. When SP Group resumed its pre-CB physical meter reading routine from 2 June 2020, the accumulated underestimated amount of consumption will be adjusted in the June or July bill. Therefore, the June or July utility bills could be higher than the April and May bills. See below for the illustration. Illustration: For consumers whose electricity meters are read during odd months Page 1 of 3 5 About 300,000 households have advanced electricity meters, and their electricity consumption is read remotely. They would be billed based on their actual consumption for April and May. Support to Households 6 As part of the Budget 2020 Care and Support Package, eligible HDB households will receive double their regular GST Voucher U-Save this year, through a one-off GST Voucher U-Save Special Payment. Eligible households with five or more members will receive an additional GST Voucher – U-Save rebate. The next round of disbursement of the regular GST Voucher U-Save rebate and GST Voucher U-Save Special Payment will be in July 2020. The first disbursement of the additional GST Voucher U-Save rebate for eligible larger households with five or more members will be in October 2020. For more information, visit www.gstvoucher.gov.sg. 7 As part of the recently announced Fortitude Budget, each household with at least one Singapore Citizen will receive a one-off $100 Solidarity Utilities Credit for doing their part in staying home during the CB period. This amount will be credited in the July or August utilities bill with SP Group and covers all property types. 8 In support of the Government’s Resilience Budget 2020 measures to freeze all government fees and charges for one year, SP Group has deferred grid charges amounting to S$343 million and maintained its grid fee to customers. What Households Can Do to Be Billed According to Actual Consumption 9 Households are encouraged to submit their own meter readings so as to be billed based on their actual consumption. 10 They can submit their meter readings via the following channels: a) SP Utilities app - Download the app from spgrp.sg/mobileapp. Go to “Explore” and select “Submit Meter”. b) SP Utilities Portal - Log on to SP Utilities Portal at spgrp.sg/UPortal. Go to “Usage” and select “Submit Meter Readings”. c) WhatsApp - Take a photo of the meter (with the meter number and meter reading clearly shown) and send to 8482 8636. d) Email – Email the meter readings to customerreading@spgroup.com.sg. e) Automated Phone System – Call 1800 222 2333 to submit meter readings via the automated option. Page 2 of 3 11 Households can refer to their SP bills for their meter submission period (refer to image below). They can submit their meter readings up to three days (by 5pm) from the scheduled meter reading date. For those who have downloaded the SP Utilities app, they can also set an alert for their meter reading submission period. Page 3 of 3

| SATURDAY, JUNE 20, 2020 | THE STRAITS TIMES | B11 2x INCREASE IN F&B/RETAIL SMEs THAT HAVE EARNED PRODUCTIVITY SOLUTIONS GRANTS B12 Adjustments to be made to meet change in demand for gas Town gas demand set to fall in heartland, rise across S’pore as economy reopens: SP Group Choo Yun Ting Utilities firm SP Group will be adjusting the gas transmission and distribution network over the next few weeks in the light of changing gas demands as Singapore enters phase two of its reopening. It expects that demand for town gas will fall in the heartland and rise across the island as food and beverage outlets resume walk- in operations, shops reopen and more people go back to work on- site. Mr Alex Yeo, the section head who manages the gas system control centre in Senoko, noted that sensors in the gas network will alert engineers to changes in demand so that supply can be re- calibrated. There was a 10 per cent overall fall in demand for town gas during the circuit breaker, largely due to the closure of some commercial and industrial operations, SP Group said. However, a spike in peak demand was observed during lunch and dinner hours, with more residents staying at home and cooking meals than before Covid- 19 hit. The typical lunch peak was from about 11am to 2pm, while the dinner high was from 5pm to 8pm. Gas consumption is typically “very low” in the wee hours from midnight to 5am, Mr Yeo added. Town gas is mainly used for cooking and heating by residential and commercial users. There was also a notable shift in demand from areas that typically see heavier loads, such as the city centre and Changi Airport, towards the heartland and high- density neighbourhoods like Punggol and Sengkang. This led the operator to implement its current strategy, which involves increasing the gas pressures within the transmission and distribution network for residential and industrial customers. It also installed additional sensors along the network between February and early March so it could better monitor load demand during the coronavirus pandemic. Simulations were conducted as well to make sure the new strategy was effective before it was implemented in early April. It has since been fine- tuned to meet changing consumer demand over the past two months, such as during the fasting month of Ramadan where there was a sharper peak in the evenings. Further adjustments are ahead: A member of the SP Group gas operations team at an offtake station conducting checks on the gas regulators. The utilities firm is adjusting the gas pressures within the transmission and distribution network for residential and industrial customers as Singapore enters phase two of its reopening. PHOTO: SP GROUP A spike in peak demand was observed during lunch and dinner hours, with more residents staying at home and cooking meals than before Covid-19 hit. The typical lunch peak was from about 11am to 2pm, while the dinner high was from 5pm to 8pm. With students headed back to school full time from June 29 and more workers likely to return to the office, a redistribution of residential demand for town gas is expected. Additional tweaks will be made to the network strategy as data is collected on changes in demand. Mr Yeo, who oversees staff who operate three eight- hour shifts around the clock at the control centre, said most adjustments to the offtake station are made remotely from the centre and indicators such as gas flow rates can be monitored in real time from there as well. Technicians and engineers conduct monthly physical checks on the equipment at offtake stations. While the operator is used to adjusting according to demand – for example, festive seasons such as Ramadan and Chinese New Year mean a spike in gas usage around meal hours – the changes due to the coronavirus pandemic are different, with sharper peaks during meal hours. “It is a very delicate process, because we have to monitor (the changes) closely and every response has to be fine- tuned along the way,” said Mr Yeo. yuntingc@sph.com.sg

Solar Power – Non-Residential Consumers (Master-Sub Write Up) Background 1 Master-sub scheme is a metering arrangement whereby the common services consumption is a derived figure: • Master-meter measures overall electricity consumed by the building (i.e. both the individual units and the common services) • Sub-meters measure the usage of subtenant units. • Common services consumption is derived based on the master reading subtracted by the sub-meters reading. 2 The subtenant’s account can be non-contestable (NCC) or contestable (CC), but the master account must be NCC. Some example of buildings under the master-sub scheme are condominiums and commercial buildings. Solar installed on master-sub buildings 3 Currently, buildings under master-sub scheme can only install solar PV system on a caseby-case basis due to the existing SP’s IT system design for this scheme: • Any export of electricity would result in the lowering of the master readings, and therefore result in inaccurate computation of the common services load. • Problem would be further exacerbated if there is high level of solar injection, potentially result in negative consumption of the common services load. • The contestability status of the subtenants would lead to further complication as consumption of NCC accounts are estimated on alternate months (based on previous months’ actual reading). 4 As such, solar PV system can only be installed if the buildings meet the following criteria: • The amount of solar generated must not exceed the consumer’s consumption 1 at any point in time, as the current IT system is unable to register any export, and SP will also not make any payments. Solar owner will need to have a PPA with either the master or the subtenants (depending who consumes the solar) if they wish to receive any payment. • SP will also not be changing the master meter to a bi-directional meter. 1 If the subtenant installs solar PV system, the solar generation cannot exceed the subtenant’s consumption. If the master installs solar PV system, the solar generation cannot exceed their common services' load. Alternative solutions to sell-back solar energy 5 While EMA and SP are working to allow master-sub buildings to sell-back excess solar generation back to the grid, this can only be implemented in the longer horizon due to the time needed to review and make IT system changes. 6 As such, there are potentially two solutions: a) Connect the solar PV system directly to the SPPG substation: For this set up, the PV will be connected directly to the grid and be treated as a separate installation from the building. As there may be constraints in the network, there could be a limit to the amount of solar PV system that the network can support. Hence, solar owners are advised to consult SP before making their investment decisions. b) Connect the solar PV’s main switchboard to consumer’s main switchboard before connecting to the grid. For this to be implementable, the solar owner will need to seek permission / agreement from the building owner to install the solar PV’s main switchboard in the building’s consumer switch room (if there is sufficient space). This is a new solution and details can be found in Annex 1. Annex 1 Terms and Conditions for Solar PV installations direct connection to grid in existing building electrical installation taking LT supply from SPPG 1. The premise owner remains accountable for the premise’s electrical installation (including Solar PV main switchboard and any new solar PV installations in the premises) under the EI licence issued by EMA. The connection agreement between SP and the premise owner will need to be amended to reflect the additional responsibility of the new solar PV installation in the connection agreement. 2. It is building LEW’s responsibility to take charge all electrical equipment and accessories in the switchroom including PV switchboard etc, and the owner of the solar PV installation will need to: a. Enter into an agreement with the premise owner given that the Solar PV main switchboard will be installed in the premise owner’s switch room and the according space will be utilised for any associated metering equipment as well as the protection devices. b. Install the generation meter at the Solar PV main switchboard and for the meter to comply with technical specifications as specified under the Metering Code. 3. The premise owner and building LEW shall ensure the following safety requirements are adhered to: a. Limit the total PV capacity by the incoming service cable to the Solar PV main switchboard. The sum of the current for the Solar PV and incoming to consumer’s main intake switchboard shall not exceed the current carrying capacity of the cable for which the Solar PV is connected to. b. Ensure both the consumer’s main intake switchboard and the Solar PV main switchboard are located inside the same main LT switch room as shown in the above diagram. c. Provide electrical inter-tripping and anti-islanding between consumer’s main intake switchboard and Solar PV main switchboard to ensure that the PV system(s) will cease to energise in the event that there is a loss of permanent grid supply to the consumer’s main intake switchboard. Ensure clear boundary and segregation of connections between the building electrical and the solar PV installation(s). The cable from the solar PV system should be housed in a separate trunking to segregate connection between building and the solar PV installation. d. The building electrical installation and solar PV installation(s) must have a common earth as per SS638’s (Formerly CP5) requirements for LV installations. The earthing for both building electrical installation and PV electrical installation are required to be bonded together if they have erected theirs own earthing systems. e. Clear labelling / marking must be displayed on consumer’s main intake switchboard and Solar PV main switchboard to demarcate PV and LT connection. This is consistent with current PV submissions where clear labelling/marking must be displayed at both main intake switchboard and Solar PV main switchboard. f. Building’s LEW to ensure safety procedures/SOP in place to address the operation of the dual supply intakes and the normal and abnormal operating conditions (i.e. emergency) Ensure the PV installation(s) shall have anti-islanding features to ensure that the PV installation(s) will cease to energise in the event that there is a loss of grid supply and continue to remain de-energised until permanent grid supply is normalised. g. LEW to ensure the supply generated by PV to be connected at the Solar PV main switchboard directly to grid without bypassing the main incoming SPPG meter. This is to ensure that the customer load supply is taken from grid source only. There shall be no connection of any non-approved on-site loads at the Solar PV main switchboard. To avoid such scenarios, the building LEW and PV LEW shall make the following declaration during CS 1 submission. h. LEW to ensure that there is no unauthorised use of energy at Solar PV main switchboard i.e. illegal tapping of supply at PV board. 4. If the load account is closed, the PV installation(s) will need to be deenergized and the generation account(s) would need to be closed. The premise owner or building LEW shall inform EMC on the deregistration of the PV Installation(s). For decommissioning of PV installations only, the LEW is required to submit CS1 application to replace the switchboard so as to regularise the setup.

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.
