Media Release Electricity Tariff Revision For The Period 1 January to 31 March 2024 Singapore, 29 December 2023 – For the period from 1 January to 31 March 2024, the electricity tariff (before GST) for households will increase by 4.1% or 1.19 cents per kWh compared with the previous quarter. The average monthly electricity bill for families living in HDB four-room flats will increase by $4.39 (before GST). This is due to higher energy costs (as detailed in Appendix 1) compared with the previous quarter. *before GST Singaporean households living in HDB flats will receive U-Save rebates in January 2024 to offset their utility including electricity bills, as part of the permanent GST Voucher (GSTV) scheme and the Assurance Package, to help defray GST and provide cost-of-living support for lower- to middle-income households. Electricity tariffs (before GST), including tariffs for non-households, will increase by an average of 4.3% or 1.18 cents per kWh compared with the previous quarter. SP Group reviews the electricity tariffs every quarter based on guidelines set by the electricity industry regulator, Energy Market Authority (EMA). Please refer to Appendix 1 for the components of the electricity tariff, Appendix 2 for the tariffs approved by EMA, and Appendix 3 for the average monthly electricity bills for households. Appendix 1 BREAKDOWN OF ELECTRICITY TARIFF The electricity tariff consists of the following four components: Energy costs (paid to the generation companies): This component is adjusted quarterly to reflect changes in the cost of power generation. Network costs (paid to SP PowerAssets): This fee is reviewed annually.   Market Support Services Fee (paid to SP Services): This fee is reviewed annually. Market Administration and Power System Operation Fee (paid to Energy Market Company and Power System Operator): This fee is reviewed annually to recover the costs of operating the electricity wholesale market and power system.   Q1 2024 TARIFF (before 9% GST) Appendix 2 ELECTRICITY TARIFFS FROM 1 JANUARY 2024 Appendix 3 AVERAGE MONTHLY ELECTRICITY BILLS OF DOMESTIC CUSTOMERS  (TARIFF WEF 1 JANUARY 2024) (before GST)

30 Jun 2016 For Immediate Release MEDIA RELEASE ELECTRICITY TARIFF REVISION FOR THE PERIOD 1 JULY TO 30 SEPTEMBER 2016 1. For the period from 1 Jul to 30 Sep 2016, electricity tariffs will increase by an average of 9.2% or 1.59 cents per kWh compared to the previous quarter. The increase is largely due to the cost of natural gas for electricity generation, which rose by 26.0% compared to second quarter 2016. This was partly offset by lower non-fuel costs, notwithstanding an increase in Market Support Services fee to meet higher market system and development costs. 2. For households, the electricity tariff will increase from 17.68 to 19.27 cents per kWh for 1 Jul to 30 Sep 2016. The average monthly electricity bill for families living in four-room HDB flats will increase by $6.79 (see Appendix 3 for the average monthly electricity bill for different household types). 3. SP Services reviews the electricity tariffs quarterly based on guidelines set by the Energy Market Authority (EMA), the electricity industry regulator. The tariffs given in Appendix 1 have been approved by the EMA. _______________________________________________________________________________________________________ Issued by: SP Services Limited 10 Pasir Panjang Road #03-01 Mapletree Business City Singapore 117438 Co.

This charge varies for different load requirements and is categorised as follows: [a) Development Without Substation The service connection charge comprises the cost based on requirement in kVA of tapping supply from both the High Tension [HT) and LT networks, which includes the cost of service cables. For individual consumers without substations, the cost of LT service cable for the same capacity may vary widely depending on their locations with respect to the nearest LT mains. These consumers are not the sole beneficiaries of the extension of the LT network. To achieve a greater degree of equity in terms of cost for these general consumers, a standard cost approach is adopted by grouping consumers with similar supply requirements. The average global cost per kVA is determined based on past statistics. For example, this category of consumers which comprises mainly landed residential owners applying for the same applied load, will pay the same standard connection charge regardless of the location of their premises from the existing LT network. [b) Development With Substation The service connection charge comprises the cost based on requirement in kVA of tapping supply from the HT network and the cost of service cable. The cost of tapping supply from the HT network refers to the cost of cables and consumables used in setting up a new distribution substation. It excludes the cost of shared network assets such as switchgear, transformer and HT network cables. The cost is spread to all new consumers proportionally on a per kVA basis. For consumers with substations, their supply intake point is usually adjacent to the substation, which requires a service cable of approximately 15m in most instances. Therefore, the standard cost of service cable is computed based on a length of 15m. Consumers shall pay the additional cost for service cable exceeding 15m. In addition, consumers shall also pay for those dedicated assets, such as switchgear and transformers, which are serving them and do not benefit others.

For longer lengths, additional charges shall apply. Standard charges are only applicable to consumers who are connected to the shared network. Standard charges are not applicable to consumers where the network extension is unlikely to be shared by others. Some of these include supply to HDB premises, premises involving installation of bigger capacity cable in order to overcome the excessive voltage drop, temporary work sites, public installations and offshore island premises. These consumers will be required to pay for the full connection network cost, based on user-pay principle, as they are the main beneficiaries. B2 Service Connection Charges for HT, EHT and UHT Supply Consumers taking HT, EHT and UHT supply shall pay the cost of the service connections to their intake equipment including cables, associated equipment and facilities to effect the connection of consumers’ equipment to SPPA’s substation/network. The service connection shall cater for single contingency. Consumers requesting for additional level of contingency that exceeds the single contingency standard are required to pay for the full cost of such provision. B3 Dedicated Network/Substation The developer or consumer shall pay the full cost of all associated equipment and facilities under a dedicated network/substation scheme for which the network capacity is intended to serve the developer’s development or consumer’s premise(s) exclusively. A substation comprises land, building, electrical equipment and associated cables. A substation which serves a development or premise has to be provided and paid for by the developer or consumer. As the capacity of electrical equipment is lumpy, the substation may have excess capacity. The developer or consumer will carry the cost of this excess capacity which cannot be avoided. As this substation is required to serve mainly the development’s or consumer’s load, it is considered a dedicated substation. To reduce cost, a developer or consumer can choose to let SPPA bear the cost of the electrical equipment and associated cables, thus making the network/substation a nondedicated one. In return, SPPA must be allowed to allocate the excess capacity to other consumers. Even after the excess capacity is allocated, SPPA shall return the capacity to the developer or consumer if his demand grows later provided existing allocated capacity to other consumers can be diverted. The latter provision shall also apply to the decommissioning of the substation. At present, most substations provided by developers or consumers are non-dedicated substations.

The Contracted Capacity shall be the supply capacity (in kW), which is requested by the consumer for that intake supply point. For the avoidance of doubt, and without prejudice to paragraph 3.1.3 herein, the consumer shall not be allowed to reduce the declared Contracted Capacity upon the signing of the Consumer Connection Agreement / Supply Agreement, notwithstanding the fact that the energisation of the new supply has still not taken place. 3.1.2 For a new connection, consumers are subject to a binding period of 5 years from the target date or the commissioning date for SPPA’s plant and equipment, except for the service cable, whichever is later. During the 5-year binding period, no reduction to the Contracted Capacity is allowed. For new HT, EHT and UHT connections, the minimum Contracted Capacity for each intake supply point is as follows : HT with 1 or 2 feeders HT with 3 or 4 feeders EHT UHT 1,700 kW, 12,751 kW, 25,501 kW, 85,000 kW. During the first year of the 5-year binding period, requests for intermediate incremental steps of Contracted Capacity may be made before the full Contracted Capacity is implemented. The first step shall be at least one quarter ( 1 /4) of the consumer’s requested full Contracted Capacity at each intake supply point. 3.1.3 After the initial 5-year binding period, the consumer may, by giving at least 10 business days’ notice in writing, reduce his Contracted Capacity at each intake supply point subject to the following minimum values: HT with 1 or 2 feeders HT with 3 or 4 feeders EHT UHT 850 kW, 6,375 kW, 12,750 kW, 42,500 kW. Any such reduction in Contracted Capacity shall be subject to a 1-year binding period from the effective date of the revised Contracted Capacity, i.e. the consumer shall not be entitled to make any further reduction in the Contracted Capacity within one year following any such reduction. The Market Support Services Licensee will inform the consumer of the date of their billing cycle. The consumer will be billed based on the revised Contracted Capacity for the entire billing cycle that encompasses the effective date of the revised Contracted Capacity. 3.1.4 The consumer, may, by giving at least 15 business days’ notice in writing, may be allowed to increase his Contracted Capacity, during the 5-year or 1-year binding period. The revised Contracted Capacity shall apply for the remainder of the initial 5-year binding period or for a minimum period of 1 year, whichever is later, provided SPPA is not required to install new or additional equipment. The consumer will be billed based on the revised Contracted Capacity for the entire billing cycle that encompasses the effective date of the revised Contracted Capacity. Reduction of Contracted Capacity during binding periods will not be allowed. 3.1.5 A consumer whose revised Contracted Capacity requires SPPA to install new or additional equipment shall be considered as receiving a new supply with a new 5-year binding period. 3.1.6 Subject to Clause 3.1.4 and 3.1.5, the UCC incurred by a consumer in a particular month (“UCC Month”) can be converted into Contracted Capacity Charge provided: (i) (ii) (iii) (iv) The consumer submits the request for an increase in Contracted Capacity no later than 2 weeks after the date of the bill for the UCC Month; The revised Contracted Capacity is not less than the maximum demand recorded in the UCC Month; The revised Contracted Capacity does not require the Transmission Licensee to install new or additional equipment; and Upon approval by the Transmission Licensee, the revised Contracted Capacity shall take effect on the first day of the UCC Month and thereafter shall not be reduced within one year, or the remaining of the 5-year binding period, whichever is later. 3.1.7 For a new development with landlord and tenants, the Contracted Capacity required by the landlord himself and his tenants (HT and above) must in aggregate meet the minimum values set out in paragraphs 3.1.2 to 3.1.3 above in order for the landlord to qualify for HT, EHT or UHT supplies. If landlord or its tenants (HT and above) request to revise their Contracted Capacity, the aggregate Contracted Capacity after revision must meet the minimum Contracted Capacity values and subject to the same terms and conditions for revision of Contracted Capacity set out in paragraphs 3.1.3 and 3.1.4. 3.1.8 Existing HT, EHT or UHT consumers may have Contracted Capacity below the minimum Contracted Capacity as specified in paragraphs 3.1.2 and 3.1.3. For such consumers, they may request to increase (but not decrease) their Contracted Capacity in the manner as described above. 3.2 Peak Period Charge The Peak Period Charge payable shall be the monthly charge based on the energy (in kWh) supplied to an installation during the peak period, 7.00 am to 11.00 pm, in that month. 3.3 Off-Peak Period Charge The Off-Peak Period Charge payable shall be the monthly charge based on the energy (in kWh) supplied to an installation during the off-peak period, 11.00 pm to 7.00 am, in that month. 3.4 Reactive Power Charge The Reactive Power Charge is a monthly charge payable in any month for the installation's excess kVArh consumption. The excess kVArh shall be the difference by which the installation's kVArh consumption drawn from the network in that month is greater than 62% of its kWh consumption drawn from the network in the same month. 3.5 Uncontracted Capacity Charge 3.5.1 The Uncontracted Capacity Charge is a monthly charge payable in any month for the Uncontracted Capacity utilised. The Uncontracted Capacity is the capacity in kW by which the maximum demand in kW (measured by the half-hour integration meter) exceeds the Contracted Capacity at that metered intake supply point. 3.5.2 The Uncontracted Capacity Charge shall apply to the following HT, EHT and UHT consumers : a. Normal consumers without embedded generation; b. Consumers with embedded generation whose monthly maximum demand in kW is the maximum summated demand in kW in the month, determined by summating the kW demand drawn from the network and the kW output from embedded generation (i.e. Summation Scheme); and c. Consumers with embedded generation who opt to cap their power demand in kW drawn from the network in the event that the maximum demand in kW (measured by the half-hour integration meter) exceeds the Contracted Capacity at that metered intake supply point (i.e. Capped Capacity Scheme or Extended Capped Capacity Scheme). The Uncontracted Capacity for these consumers shall be limited to 20% of the Contracted Capacity. 3.6 Uncontracted Standby Capacity Charge 3.6.1 The Uncontracted Standby Capacity Charge is a monthly charge payable in any month for the Uncontracted Standby Capacity utilised. The Uncontracted Standby Capacity Charge shall apply to those HT, EHT and UHT consumers with embedded generation who opt for the Capped Capacity Scheme or Extended Capped Capacity Scheme. 3.6.2 For Capped Capacity Scheme, the Uncontracted Standby Capacity Charge applies in the event the demand in kW drawn from the network (measured by the power meter) exceeds 120% of the Contracted Capacity at that metered intake supply point for a duration of more than 10 seconds continuously. 3.6.3 For Extended Capped Capacity Scheme, the Uncontracted Standby Capacity Charge applies in the event : • the demand in kW drawn from the network exceeds 120% and up to 200% of the Contracted Capacity at that metered intake supply point for a duration of more than 100 seconds continuously; or • the demand in kW drawn from the network exceeds 200% of the Contracted Capacity at that metered intake supply point for a duration of more than 10 seconds continuously. 3.6.4 For the avoidance of doubt, in the event Uncontracted Standby Capacity Charge applies in accordance with Clauses 3.6.2 and 3.6.3 above, Uncontracted Capacity Charge shall also be applicable for the Contracted Capacity portion which is 20% above the customer’s declared Contracted Capacity. 4 Temporary Supplies Temporary Supplies apply only to LT and HT supplies for temporary civil engineering and building construction sites. The UOS charges applicable for the LT and HT temporary supplies shall be the same as those used for LT and HT supplies respectively. For temporary supplies at HT, the Contracted Capacity shall apply for a binding period of 2 years. Upward revision of the Contracted Capacity may be allowed during the validity of the binding period of the Contracted Capacity. The revised Contracted Capacity shall in such cases apply for a minimum period of 1 year, provided SPPA is not required to install new or additional equipment. Downward revision during such binding period will not be allowed. A consumer whose revised Contracted Capacity requires SPPA to install new or additional equipment, shall be considered as receiving a new temporary supply. The term granted for temporary connection is 2 years.

SP Energy HubAnnual ReportReliabilitySustainabilityInnovation 38 Years with SP: Growing through Change RELIABILITY Maizan Binte Abdullah, Senior Technician from Condition Monitoring (CM), manages a team of 10 to perform health checks across substations in the north of Singapore. Her team collates and analyses recorded measurements and checks for anomalies in switchgears and transformers. Maizan Binte Abdullah performing condition monitoring checks. (Photo was taken before circuit breaker) When Maizan joined SP 38 years ago, she was doing something quite different. Learning and Adapting After completing her post-secondary education, Maizan started as an apprentice in the Electro Mechanical Maintenance Fitting department at the Public Utilities Board (PUB). Subsequently, she was posted to the Meters section to conduct meter maintenance activities. Maizan (in blue attire) and her former colleagues from Meters section enjoying a durian feast together. When PUB corporatised in 1995, she moved to SP where she continued with the Meters section for the next 14 years. She would have thought that would be her home for the rest of her career. However in 2019, she was seconded to CM. This change to field work seemed to be unsurmountable, having been in a deskbound administrative role for more than 20 years. “Given my age, I was very worried that I may not be able to cope with the demands of the new role. However, I recognised that I needed to move out of my comfort zone and acquire new skills to remain relevant,” shared Maizan. After going through training and with strong support from her team and the management, Maizan is settling so well at CM that she became the team lead for North Zone in the same year. A lifelong learner, Maizan completed her part-time Diploma in Engineering (Power Engineering) programme at Singapore Polytechnic in May 2020 under SP’s sponsorship. She soldiered on despite having to juggle her new role and studies. “There were times when I felt overwhelmed and felt like giving up. I am glad I had the support from my family, my boss and colleagues who encouraged me to persevere. This experience has been very enriching, and I look forward to continue growing!” exclaimed Maizan. Growing despite COVID-19 With this mindset, Maizan and her team continued to learn new ways of working to carry out their duties during the Circuit Breaker period. Maizan and her colleagues use handheld detectors to detect for abnormalities in the network. This is to prevent faults from developing and causing power disruptions. “Due to the need to minimise contact, we had to stagger our working hours. This is a challenge as CM relies heavily on teamwork. We also had to wear a mask when doing checks in the substation, which is an enclosed space and often hot and humid,” shared Maizan. However, Maizan takes it in her stride. She performs daily check-ins with her team members via instant messaging and tele-conferencing. With a sparkle in her eyes, she said, “Work is never the same every day. I take this as an opportunity to grow – to be stronger and better in managing change and future crises.” — 27 July 2020 TAGS LIFELONG LEARNERPEOPLE OF SPRELIABILITYCONDITION MONITORING YOU MIGHT BE INTERESTED TO READ Ground feedback, digital tools: How she helps 8,000 workers end their day safely Faster repairs, fewer disruptions: Meet the innovative teams using smart tech to keep your piped gas supply flowing Engineer, 27, shares how she is undaunted by male-dominated energy industry & climbs the ranks

SP Energy HubAnnual ReportReliabilitySustainabilityInnovation Safeguarding the Backbone of Singapore’s Grid RELIABILITY The transmission substations that Kane Neo oversees are key to keeping Singapore powered Kane Neo and his team protect a part of the power world that is invisible to most – the high voltage transmission networks. These networks form the backbone of Singapore’s electricity infrastructure, connecting power from the power generation plant to the distribution networks that connect it to our customers. “Power that runs through transmission networks can be massive – ranging from 66kV to 400kV. When running at full capacity, one 230kV transmission substation can power up to eight towns, each the size of Toa Payoh,” explains the 47-year-old, General Manager of SP’s power grid business.  He first discovered his passion for power engineering when studying at Ngee Ann Polytechnic. Power is generated at very high voltage, travelling through these networks before being progressively “stepped down” at the transmission substations. Through various distribution substations, power is sent via smaller cables of the network to homes and offices. “The work we do is highly sensitive and teamwork is important. Any issue on the transmission network can cause a huge impact,” he adds. A transmission substation, which feeds into many distribution substations, can affect several estates if it faces disruption, he says.   At SP, the path to become a transmission engineer spans about four years of on-the-job training and structured courses. Regular health checks on transmission assets such as cables, switchgears and transformers form a critical part of the job for Kane and his team of over 160. The size, importance and complexity of the equipment do not make this easy. For instance, Kane’s team keeps a close watch on transmission cables, which run for approximately 2,600km, and some 3,000 transmission assets island-wide. Any anomalies that may impact transmission assets, are detected early using data from sensors and rectified. Stringent checks include tests on the quality of gas that insulates the high voltage equipment. “If we detect a problem, it needs to be solved in the shortest amount of time, and we persist until we get to the bottom of it,” says Kane, who has been with SP since 2000 and spent the last three years in his current role. He also has a decade of experience working on the distribution network. For Kane and his team, it means constantly being on the alert, pre-empting possible issues and finding ways to make the network more robust. Kane (second from left) with his family (from left) Le Wei, Julie and Le Xuan. While few understand the scale and significance of the transmission network, or the invisible heroes that keep it going, his 12- and 13-year-old daughters do. Le Wei and Le Xuan, are able to spot the various transmission substations when they go out on drives as a family. “As they enjoy modern conveniences, they are also more keenly aware of what it takes to power their lives and the nation daily,” he says. — 17 October 2019 TAGS PEOPLE OF SPRELIABILITY YOU MIGHT BE INTERESTED TO READ Ground feedback, digital tools: How she helps 8,000 workers end their day safely Faster repairs, fewer disruptions: Meet the innovative teams using smart tech to keep your piped gas supply flowing Engineer, 27, shares how she is undaunted by male-dominated energy industry & climbs the ranks
