SP Energy HubAnnual ReportReliabilitySustainabilityInnovation Protecting Our Underground Network RELIABILITY Principal Engineer James Ou and his team conduct checks on worksites to ensure electricity cables and gas pipes are not compromised. When a patrol officer from SP Group’s Earthworks Surveillance & Patrolling (ESP) section pulled up at a Whampoa West construction worksite in November last year, what he did not expect to find was an excavated trench right over one of SP’s 230kV transmission cables – and a water pipe laid above it. The checks by ESP had uncovered the non-compliance of a contractor who was not following the approved plans they submitted to SP previously. Beyond the works themselves, leaks, condensation or breaks in the water pipe could pose a threat to the high voltage electricity cable below, and cause a power outage. SP’s critical electricity cables and gas pipes – networks spanning 11,500km and over 28,000km respectively – are buried underground. At the same time, across Singapore, there are always ongoing works for various construction projects. “That is why we carefully manage and monitor all excavation works – it minimises the risk of an electricity disruption or a gas leak,” explained Principal Engineer, James Ou, who heads ESP and oversees a team of almost 60. Detect and protect: Technical officer Mohamed Saiful Matsaid (left) uses a cable locator to detect electricity cables hidden underground as Principal Engineer James Ou (right) marks out the path of the cable. Mr Ou, who is 36 and studied electrical engineering, joined SP in 2008. He worked in electricity operations and maintenance before assuming his current role in November 2017. Now, he prevents problems instead of fixing them. In the case mentioned, the contractor of another organisation had conducted unauthorised work. Timely intervention averted damage, but the site’s Registered Excavator Operator was still suspended from excavation work for three months. The Energy Market Authority also took action against the contractor. Damage control: When contractors do not comply with requirements, Earthworks Surveillance and Patrol officers will issue a “stop-work” order. The incident highlights the critical role SP’s compliance officers play in keeping Singapore’s electricity and gas supply humming – especially against its booming construction landscape. Despite the acronym, the ESP team doesn’t rely on a sixth sense to warn them of danger. Instead they enforce stringent requirements, as well as rigorous and frequent checks on every worksite. 15 patrol officers in the team of close to 60 Earthworks Surveillance and Patrol Officers cover a total distance of 360,000km – or nine trips around the earth – each year. That’s an average of 135 worksites a single patroller visits each month, said Mr Ou. Checks are frequent – for sites close to gas pipes, checks are conducted daily. For transmission cables over 66kV, checks are conducted three times a week. There are many bases to cover. All contractors need to submit a notice of commencement of earthworks (NCE) seven days before they are scheduled to begin. They are also briefed on precautions and mitigation measures onsite by ESP officers. SP is also consulted on high-risk earthwork sites to ensure nothing is missed. This minimises the risk of damage.   During site meetings conducted by ESP officers, all requirements are covered, and SP patrollers ensure they are followed. Senior officers like Mr Ou will also join patrols or attend briefings to ensure contractors get clear and complete guidance. Part of the team: SP Earthworks Surveillance and Patrol officers join site briefings and guide contractors and workmen on how to best to protect critical cables and underground pipes during works. Most contractors do take compliance seriously, says Mr Ou. “Sometimes, it is subcontractors that just don’t know the procedures, or shift the location of their work, and it poses a risk,” he said. The team’s diligent checks and contractors’ compliance with regulations minimises that risk. This protects both our critical infrastructure and the workers at these sites. Getting the job done right requires a “high-trust” environment, and the same openness and teamwork demanded by sports, says Mr Ou, who plays football in an amateur league on weekends. He also conducts monthly huddles with his team, and encourages all officers regardless of rank to speak freely if they have suggestions or spot anything amiss. “I recognise it is important to have each other’s back when working on something critical, and to come together as a team. “Everyone has a part to play and can add value.” — 11 July 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

Media Release Electricity Tariff Revision for the Period 1 October to 31 December 2025 Singapore, 30 September 2025 – For the period from 1 October to 31 December 2025, the electricity tariffs (before GST) for households will increase by 0.3% or 0.08 cent per kWh compared with the previous quarter due to higher energy costs.  The average monthly electricity bill for families living in HDB four-room flats will increase by $0.31 (before GST). * before GST The overall electricity tariff (before GST), including tariffs for non-households, will increase by an average of 0.3% or 0.08 cent 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). The energy cost component of the electricity tariffs for each quarter is set using the average natural gas prices in the first two and a half months in the preceding quarter.  The electricity tariffs may fluctuate quarter to quarter due to volatile global fuel prices driven by geopolitical factors. Please refer to Appendix 1 for the components of the electricity tariff, Appendix 2 for the electricity tariffs approved by EMA, and Appendix 3 for the average monthly electricity bill 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 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. Network costs (paid to SP Group): This is to recover the cost of transporting electricity through the power grid. Market Support Services Fee (paid to SP Group): This is to recover the costs of billing and meter reading, data management and retail market systems. 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.

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.

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.

SP Energy HubAnnual ReportReliabilitySustainabilityInnovation Pushing boundaries to impact future generations RELIABILITY Managing high voltage equipment is all in a day’s work for our senior engineer Tan Jie Yi. She works in the Transmission Operation and Maintenance team, part of the 24/7 operations that contribute to Singapore’s world-class network reliability. No detail is too small when conducting maintenance work for switchgears – key components in the smooth distribution of electricity to customers in industries, businesses and households. With 13 years of engineering experience under her belt, Jie Yi is unfazed by the technical and hands-on nature of her job. Join us as we discover how Jie Yi’s career has come “full circle” for her and has fuelled her passion in engineering. Tan Jie Yi, Senior Engineer in Transmission Operation and Maintenance team, finds joy and fulfilment in keeping the nation’s world-class electricity grid running. Finding her path into the engineering industry more than a decade ago, Jie Yi’s passion for scaling new heights led her to where she is today in SP Group. Formerly in the switchgear manufacturing industry, Jie Yi literally switched gears when she joined SP, as she deepened her technical expertise by learning to manage the full cycle of switchgears – from installation to maintenance. “Now that I’m on the client side, I can better appreciate the priorities and challenges faced during maintenance and understand how we can address them during the project installation phase. Like most engineers, I enjoy problem-solving. The adrenaline rush keeps me going!”   Here, we see Jie Yi assisting to perform switching work in a transmission substation. Electrical networks have to be shut down safely before maintenance work can be carried out. The team performs equipment maintenance and renewal according to a rigorous schedule. When asked about what it takes to prove her mettle in a field that has been conventionally male-dominated, Jie Yi’s advice is to strengthen one’s competency. “You need to put in effort to have sound knowledge of the operations and protocols. Gender doesn’t get in the way when you can stand up to the quality of your work.” Jie Yi is currently undergoing training to attain her switching certificate. This will allow her to operate high-voltage equipment independently. Jie Yi’s advice to those interested in engineering is to start from ground up to build a strong knowledge foundation, and always be hungry to know and learn more. “When you start from the bottom, there is nowhere to go but up,” she shares. This philosophy is mirrored in her own career, where she started as an engineering assistant and worked her way up to become a project manager. To Jie Yi and her team, they believe that the work they are doing today, is an investment for generations to come. This also holds true as she embarked on a new journey as a first-time mum to twins!  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
