Singapore Power Group
SP Group is a state-owned holding company that owns and operates Singapore's electricity and gas transmission and distribution networks, ensuring reliable energy delivery to households and businesses nationwide.[1][2] Established in 1995 as the corporatized entity of the former Public Utilities Board's electricity and piped gas operations under Temasek Holdings, it maintains an extensive infrastructure exceeding 4,800 kilometers of cables and pipelines, achieving system reliability rates above 99.99%.[3][4][2] SP Group serves approximately 1.7 million customers in Singapore and has expanded regionally into sustainable solutions, including district cooling, renewable energy integration, electric vehicle charging, and digital energy platforms across Asia Pacific markets such as Australia, China, Thailand, and Vietnam.[1] Its operations emphasize efficiency and low-carbon transitions, contributing to Singapore's energy security through investments in smart grid technologies and international asset stakes, such as a 40% holding in Australian networks.[1][5]History
Founding and Nationalization Context
The electricity and gas sectors in Singapore were brought under centralized government control through the establishment of the Public Utilities Board (PUB) on 1 May 1963, as a statutory board under the Public Utilities Ordinance, tasked with coordinating the supply of these utilities alongside water, taking over responsibilities previously handled by the City Council and other entities.[6][7] This move consolidated fragmented municipal and private operations into a state monopoly, reflecting post-colonial efforts to ensure reliable infrastructure amid rapid urbanization and independence in 1965, with PUB operating as a vertically integrated entity responsible for generation, transmission, distribution, and retail.[8] By the early 1990s, PUB managed over 1,000 megawatts of installed electricity capacity and supplied piped gas to households and industries, but faced pressures for modernization to support economic growth.[9] In response to these demands, the Singapore government pursued corporatization to enhance operational efficiency and commercial orientation without relinquishing ownership, leading to the formation of Singapore Power Limited (SP) on 1 October 1995 as the entity to assume PUB's electricity and piped gas undertakings.[10][11] SP was structured as a wholly owned subsidiary of the government-linked Temasek Holdings, maintaining public ownership while introducing private-sector management practices, with initial assets including transmission networks spanning 3,000 kilometers for electricity and gas pipelines serving 800,000 customers.[4] This transition separated utilities from PUB, which refocused on water, and marked the beginning of SP Group's role as a state-controlled utility monopoly, emphasizing reliability over competition at the time.[12] The corporatization aligned with Singapore's broader strategy of state-directed capitalism, where utilities remained nationalized in practice through government equity, avoiding full privatization to safeguard essential services amid vulnerabilities like dependence on imported fuels.[13] Early performance under SP demonstrated high efficiency, with system losses below 3% and outage durations averaging under 1 minute per customer annually by the late 1990s, underscoring the benefits of integrated state oversight prior to subsequent market reforms.[14]Expansion into Gas and Early Reforms
On October 1, 1995, Singapore Power Limited was incorporated under Temasek Holdings to assume the electricity transmission and distribution functions, along with the piped gas supply operations, from the Public Utilities Board (PUB), which retained responsibility for water services.[10][15] This transfer included PUB's existing gas network, which primarily distributed town gas derived from naphtha processing at facilities like the Kallang Gasworks, serving residential, commercial, and industrial users for cooking and heating.[16] PowerGas Limited, a key subsidiary, was registered on June 27, 1995, to handle gas transmission and distribution, positioning Singapore Power to expand beyond town gas amid Singapore's shift toward imported natural gas for power generation.[17] Initial natural gas imports via pipeline from Indonesia's Batam region began in limited volumes under PUB in the early 1990s, but Singapore Power accelerated infrastructure development post-1995, including extensions to the high-pressure transmission network to deliver gas to power plants.[18] By 2001, the first major long-term piped natural gas supply agreement was secured, enabling natural gas to supplant fuel oil and town gas derivatives, which rose to comprise over 90% of electricity fuel by the mid-2000s.[19] This expansion reduced reliance on manufactured gas, improved efficiency, and supported lower emissions, with PowerGas constructing over 3,000 kilometers of pipelines by the early 2000s to connect import points and end-users.[5] Early reforms focused on corporatization to enhance operational efficiency and lay groundwork for competition, unbundling PUB's vertically integrated model by separating generation assets—transferred to independent entities like Senoko Power— from transmission and distribution under Singapore Power's monopoly regulation.[10] The Energy Market Authority (EMA), formed in 1995, regulated these changes, enforcing performance standards and tariff controls while prohibiting cross-subsidization between electricity and gas.[20] In March 2000, the government announced plans to liberalize the gas sector, granting third-party access to PowerGas's transmission network for alternative shippers, which aimed to diversify supply sources and mitigate risks from single-pipeline dependency.[15] These measures, implemented progressively through 2002 with City Gas assuming town gas retail, preserved reliability—evidenced by near-100% supply uptime—while transitioning to a contestable downstream market.[21]Restructuring and Modernization (2000s–Present)
In the early 2000s, Singapore Power underwent significant restructuring as part of broader electricity sector reforms aimed at enhancing competition and efficiency. By April 1, 2001, Singapore Power divested its ownership of generation companies, transferring them to Temasek Holdings to separate generation from transmission and distribution activities, thereby fostering a competitive wholesale market.[10] This unbundling aligned with the introduction of the New Electricity Market (NEMS) framework on the same date, which established half-hourly wholesale pricing and progressive retail liberalization starting with large consumers.[22] Singapore Power refocused on non-competitive functions, retaining responsibility for transmission, distribution, and piped gas networks while SP Services transitioned into the sole Market Support Services Licensee (MSSL), handling billing, metering, and customer connections without direct retailing.[13] Subsequent reforms extended liberalization to smaller consumers, culminating in the full Open Electricity Market (OEM) rollout for households by November 2018, enabling choice among retailers while SP Services maintained its MSSL role for universal service obligations.[23] These changes improved sector efficiency, with studies attributing gains to deregulation's emphasis on competitive generation bidding and regulated monopoly operations in grids.[13] By the late 2000s, the Singapore Power Group structure solidified, encompassing SP PowerAssets for asset investment, SP PowerGrid for transmission, and SP Services for distribution support, under wholly-owned Temasek subsidiary Singapore Power Limited.[24] Modernization efforts from the 2010s onward emphasized digital integration and grid resilience amid rising demand and energy transition pressures. SP Group developed in-house digital tools, including asset dashboards and AI-driven predictive analytics, to monitor grid health and integrate distributed energy resources like solar.[25] Key initiatives included the Smart Grid Index (SGI), launched to benchmark global grid maturity across dimensions such as automation and renewables integration, with Singapore's grid scoring highly in reliability metrics.[26] In collaboration with the Energy Market Authority (EMA), SP Group advanced virtual power plants (VPPs) and advanced metering infrastructure to manage proliferating rooftop solar, targeting a 2 GW solar capacity by 2030 while maintaining system stability.[27][28] Recent enhancements include the 2023 rollout of AI-enhanced grid monitoring for real-time fault prediction and the August 2025 acquisition of full ownership in Power Automation to bolster smart grid control and digital energy solutions.[29][30] These measures support Singapore's decarbonization goals, including importing low-carbon hydrogen and LNG while upgrading the 6,500 km electricity network to handle electrification in transport and industry.[27] Overall, restructuring has shifted SP Group from integrated utility to specialized grid operator, with modernization prioritizing data-driven resilience over expansion into contested generation.[13]Corporate Structure and Ownership

SP Group has established multiple joint ventures and strategic partnerships to advance district cooling systems, renewable energy projects, and integrated energy solutions, with a focus on sustainability and regional expansion in Asia. These collaborations leverage SP Group's expertise in energy infrastructure alongside partners' technological and financial capabilities.[40] In Singapore, SP Group formed a joint venture with Daikin Airconditioning (Singapore) Pte Ltd on 18 May 2022 to develop the country's largest industrial district cooling system at Ang Mo Kio TechnoPark for STMicroelectronics. The project, with SP Group holding 70% ownership and Daikin 30%, features a cooling capacity of up to 36,000 refrigerant tonnes and incorporates energy-efficient technologies like a 2,000-tonne HFO chiller with zero ozone depletion potential. Expected to achieve 20% annual savings in cooling-related electricity for STMicroelectronics and support its carbon neutrality goal by 2027, the system commenced operations in October 2025.[40][41] Internationally, SP Group partnered with Banpu NEXT to create BNSP Smart Tech joint venture, securing a tender on 25 September 2023 for Thailand's Government Complex Center Zone C in Bangkok. This district cooling initiative provides 14,000 refrigeration tonnes capacity across 660,000 square meters, delivering 20% energy savings, annual cost reductions of approximately 40 million baht (SGD 1.57 million), and carbon emission cuts of about 3,000 tonnes yearly, with completion in 2024 under a 20-year contract. The project also includes EV charging infrastructure and potential solar integration.[42] In China, SP Group signed a joint venture agreement with Jinko Power Technology Co. Ltd. on 11 May 2021 to acquire and develop renewable assets, starting with 102 MWp of rooftop solar in the Yangtze River Delta region (Jiangsu, Zhejiang, Shanghai), where SP Group owns 60%. Complementing this, Sino-Singapore Energy Services (SSES), a 2021 joint venture with Chongqing Gas Group, operates integrated energy systems, including a district cooling and heating project awarded in August 2025 for Chongqing East Railway Station, China's largest western high-speed rail hub. Additionally, a May 2024 strategic alliance with CMB Financial Leasing Co., Ltd., via SP Group's Shirui Energy subsidiary, commits up to RMB 8 billion (SGD 1.53 billion) over three years for financing solar farms, energy storage, and district systems.[43][44][45] SP Group also pursues strategic memoranda of understanding, such as the one with BCG Energy in Vietnam to co-invest in solar projects and bolster electricity supply. These efforts align with ASEAN energy interconnectivity goals, including feasibility studies for power links with neighbors.[46]Overseas Investments and Divestitures
SP Group maintains a significant overseas presence primarily through its 40% stake in SGSP (Australia) Assets Pty Ltd, operating as Jemena, which manages electricity distribution networks serving over 500,000 customers and gas transmission pipelines covering approximately 18,000 kilometers across New South Wales, Victoria, and South Australia.[47] This holding originated from SP Group's acquisition of Alinta in 2007, followed by asset reallocations.[48] In 2023, SP Group engaged Goldman Sachs to explore selling this stake, valued potentially over A$5 billion, attracting bids from infrastructure investors including Global Infrastructure Partners and Stonepeak; however, the process was paused by November 2024 amid market conditions.[49][50][51] Earlier Australian investments included a controlling interest in AusNet Services (formerly SP AusNet), where SP Group held 51% as of the early 2010s, operating electricity and gas networks for 1.4 million customers.[52] In 2013, SP Group divested 19.9% of its AusNet stake to State Grid Corporation of China for approximately A$1.1 billion, reducing its exposure.[53] By January 2014, it completed further sales of remaining Australian stakes, including additional AusNet shares and interests in SPI Australia Assets, to State Grid units, streamlining its portfolio toward core operations.[54] In recent years, SP Group has shifted toward renewable energy investments in Asia to support its sustainability goals. In Vietnam, it acquired its first utility-scale solar farm assets in March 2023, comprising two facilities expected to generate 130 GWh of clean electricity annually for the national grid, as part of a broader 1.5 GW development pipeline.[55][56] Complementary partnerships include a July 2025 collaboration with Hoa Sen Group for rooftop solar and industrial cooling-as-a-service at steel manufacturing sites, and a February 2025 green financing tie-up with BIDV to expand sustainable projects.[57][58] SP Group's expansions in China include a September 2024 commitment to a 240 MWp agrivoltaic solar project in Guangdong province—its largest such investment there—integrating crop farming under panels, alongside an agreement for up to 150 MWp of rooftop photovoltaic assets from Shanghai Unisun New Energy.[59][60] In Thailand, its November 2024 acquisition of 13 MWp solar PV assets marked its first M&A deals in the country, enhancing distributed generation capabilities.[61] These initiatives reflect a strategic pivot to low-carbon assets, with no major overseas divestitures reported since the Australian exits.[62]Operations and Infrastructure
Electricity Transmission and Distribution
SP Group owns and operates Singapore's national electricity transmission and distribution network, delivering power from generation plants to over 1.7 million industrial, commercial, and residential customers.[5] The network encompasses more than 28,000 kilometers of mostly underground cables, which facilitate efficient and resilient power flow across the city-state's dense urban landscape.[5] [63] Transmission infrastructure operates at high voltages of 400 kV and 230 kV, stepping down power at transmission substations before distribution at lower levels of 66 kV, 22 kV, and 6.6 kV.[64] [65] A single 230 kV transmission substation, when at full capacity, can supply electricity equivalent to eight towns the size of Toa Payoh, underscoring the system's scale in supporting Singapore's high-density demand.[65] The network includes approximately 12,000 substations for voltage transformation and distribution, with ongoing enhancements such as 40 kilometers of underground cable tunnels completed in 2019, buried up to 60 meters deep and engineered for a 120-year lifespan to mitigate surface disruptions and improve long-term reliability.[5] Distribution operations are managed through SP Services, a subsidiary handling metering, billing, and last-mile delivery, with round-the-clock monitoring from control centers to enable preventive maintenance and rapid fault response.[5] Singapore's grid achieves exceptional reliability, with customers experiencing an average of just 0.15 minutes of interruption annually based on 2020 benchmarking data, positioning it among the world's most dependable urban networks.[5] Recent projects include Southeast Asia's first large-scale 230 kV underground substation at Labrador, announced in 2021, which integrates power infrastructure beneath commercial developments to optimize land use in space-constrained Singapore.[66] These features collectively ensure stable supply amid growing demand, with total electricity consumption reaching approximately 57 TWh in 2023, predominantly from natural gas-fired generation.[67]Gas Networks and Supply
SP Group, through its subsidiary PowerGas Limited, owns and operates Singapore's gas transmission and distribution infrastructure, which spans over 2,600 kilometers of mostly underground pipelines as of 2022.[68] PowerGas serves as the licensed gas importer and transporter, delivering both natural gas and town gas to approximately 1.1 million customers, including power generation facilities, industries, and households.[69] SP PowerGrid Ltd acts as the Gas Transporter Agent, licensed by the Energy Market Authority to maintain and operate the piped gas network on PowerGas's behalf, ensuring 24/7 reliability for supply continuity.[70] Natural gas, comprising the majority of supply for power generation and large industrial users, is imported primarily via submarine pipelines from Indonesia's Batam and Malaysia, supplemented by liquefied natural gas (LNG) received at the Jurong Island terminal, which PowerGas developed and operates with an initial capacity of about 3.5 million tonnes per annum.[71] Approximately 95% of imported gas is transported daily to power plants, supporting over 95% of Singapore's electricity generation.[5] Transmission occurs at high pressures of 28 to 40 barg, transitioning to distribution at 3 to 6 barg for end-users, with around 200 major commercial and industrial customers connected.[70] Town gas, produced domestically at the Senoko Gasworks by City Energy Pte Ltd (a former PowerGas affiliate separated in 2002), caters mainly to residential and smaller commercial cooking and heating needs, serving nearly 900,000 customers.[21] It is transmitted at 3 barg and distributed at pressures from 1 kPa to 50 kPa via a separate network.[70] The dual-network system maintains segregation between natural and town gas to prevent contamination, with SP Group's gas operations team employing smart sensors, pipeline cameras, and predictive maintenance to preempt faults and uphold supply reliability exceeding 99.99%.[72]Ancillary Services and Market Support
SP Services Ltd, a subsidiary of SP Group, serves as the Market Support Services Licensee (MSSL) designated by Singapore's Energy Market Authority (EMA), handling critical operational functions to enable the competitive wholesale electricity market.[73] These include meter reading, data validation and management, billing settlement, customer enrollment and switching facilitation, and dispute resolution for over 1.4 million industrial, commercial, and residential consumers.[2][74] The MSSL role ensures seamless integration between generators, retailers, and end-users, with SP Services procuring electricity in bulk from the wholesale market via retailers or directly for contestable consumers under the Open Electricity Market framework.[23] Costs for these services are recovered through an annually reviewed Market Support Services Fee incorporated into consumer tariffs.[75] In parallel, SP Group contributes to ancillary services—essential for grid stability, including frequency regulation, voltage control, and contingency reserves—primarily through its transmission and distribution infrastructure managed by SP PowerAssets and emerging distributed energy resources (DERs).[76] While generators traditionally supply most ancillary services via Energy Market Company (EMC) procurement, SP Group partners with EMA on energy storage deployments, such as battery systems operational since 2019, which deliver frequency regulation and other ancillary support to maintain system reliability amid rising demand.[77] As of 2024, SP Group has initiated DER Management System (DERMS) pilots to aggregate and orchestrate DERs like rooftop solar and electric vehicle chargers, enabling virtual power plants (VPPs) to offer ancillary services such as demand response and peak smoothing.[78] These efforts align with Singapore's Future Grid Capabilities Roadmap, released in October 2024, which emphasizes leveraging DERs for ancillary provision to enhance resilience without expanding traditional infrastructure.[79] A 2025 pilot under SP Group's Annual Report evaluates virtual aggregation for grid-stabilizing ancillary contributions, marking a shift toward distributed, market-based support amid increasing electrification and intermittent renewables.[3] This positions SP Group to bridge legacy market support with next-generation ancillary capabilities, though full-scale implementation depends on regulatory evolution and technology maturation.[77]Innovation and Energy Transition
Smart Grid and Digital Initiatives
SP Group has spearheaded the deployment of advanced electricity meters across Singapore, targeting installation in all 1.58 million household accounts by 2026 to enable half-hourly consumption tracking via the SP App and billing based on actual usage rather than estimates.[80] This initiative supports energy efficiency by allowing households to monitor and adjust usage patterns in real time, with rollout prioritized by meter age and infrastructure needs.[80] To enhance grid resilience, SP Group is developing a Grid Digital Twin, comprising Digital Asset Twin (using AI, sensors, and dashboards for asset health) and Digital Network Twin (employing MESMO software and SITEM models), in collaboration with Nanyang Technological University, the Energy Market Authority, A*STAR, and others.[25] The project aims for pilot deployment by 2025 across 18,000 transformers and 12,000 substations to optimize maintenance, integrate electric vehicle infrastructure, and facilitate cleaner energy adoption.[25] Complementing this, the Distributed Energy Resource Management System (DERMS) provides real-time monitoring and control for distributed resources such as solar photovoltaics, battery energy storage systems, and electric vehicles, with pilots testing solar forecasting and EV integration at select substations to balance reliability and costs.[25][81] In partnership with the Energy Market Authority, SP Group is contributing to the Future Grid Capabilities Roadmap, which addresses challenges from rising distributed energy resources—including rooftop solar, battery storage, and EV chargers—by emphasizing digital tools like digital twins and DERMS for improved planning, control, and renewable integration.[27] The roadmap supports a 15 MW Virtual Power Plant sandbox launching in late 2024 to harness these resources for grid stability and demand response.[27] Further advancing integration, SP Group is piloting vehicle-to-grid (V2G) and smart charging (V1G) technologies with The Mobility House to enable bidirectional energy flow from electric vehicles, aiding renewable utilization.[81] SP Group's S$30 million joint laboratory with Nanyang Technological University, established at the NTU Smart Campus, conducts research on network resilience, housing 60 researchers and supporting 85 students in developing smart grid solutions.[81] Additionally, the company publishes the annual Smart Grid Index, benchmarking 92 utilities across 36 countries on seven dimensions—including data analytics, distributed energy resource integration, and advanced metering infrastructure—to guide global grid enhancements, with Asia-Pacific scoring 78.2% in 2024.[26]Sustainability and Low-Carbon Strategies
SP Group aligns its sustainability efforts with Strategy 2030, which seeks to establish a low-carbon, smart energy ecosystem in Singapore while positioning the company as a regional leader in sustainable solutions.[82] This framework emphasizes four pillars: advancing grid infrastructure for future demands, enabling energy transitions through integrated technologies, optimizing internal operations for efficiency, and fostering community engagement.[82] As Singapore's national grid operator, SP Group prioritizes integrating low-carbon sources to support the nation's net-zero emissions goal by 2050, given the country's reliance on imported energy and limited domestic renewable potential.[82][83] Central to these strategies is the facilitation of low-carbon electricity integration, including imports targeting 6 GWp by 2035—up from an initial 4 GWp—and domestic solar deployment, with 1.54 GWp connected by fiscal year 2024/25 and a further target of 2 GWp by 2030.[82] The company also prepares for hydrogen-ready power plants and trials SF6-free switchgear to minimize high-global-warming-potential gases in transmission equipment.[82] In fiscal year 2024/25, SP Group connected 1,683 MW of low-carbon generation capacity to the grid, contributing to Singapore's broader aim of deriving up to 40% of electricity from low-carbon sources by 2035.[82] Emission reduction efforts yielded Scope 1 emissions of 69,513 tCO2e in fiscal year 2024/25, a 1.2% decrease year-over-year, and Scope 2 emissions of 362,808 tCO2e, down 7.6%, with an overall intensity of 8 kgCO2e per MWh, reduced by 10.8%.[82] These metrics reflect investments of S$620.8 million in transition-related opportunities, alongside operational efficiencies in gas and electricity networks.[82] SP Group reports alignment with United Nations Sustainable Development Goal 7 for affordable and clean energy, while self-reported data in annual sustainability reviews provide transparency on progress, though independent verification of long-term net-zero pathways remains essential for assessing feasibility amid Singapore's gas-dependent baseline.[84][82] Key initiatives include expanding renewable energy solutions such as rooftop photovoltaic systems, aquavoltaics, and agrivoltaics, often paired with energy storage to address intermittency.[85] For instance, a 90 MW aquavoltaic farm in Qingdao, China, generates 162 million kWh annually and avoids 160,000 tCO2e, while a 78 MWp agrivoltaics project in Guangdong yields 91.3 GWh yearly and cuts 91,000 tCO2e.[85] Domestically and regionally, SP Group deploys over 2,100 EV charging points in Singapore, targeting 60,000 by 2030, and has electrified 54% of its fleet by 2025, aiming for 100% of regular vehicles by 2026.[82] District cooling systems, with 292,000 RT capacity, further enhance efficiency; overseas examples include projects in Chengdu (1,700 tCO2e annual reduction starting 2026) and Thailand (3,000 tCO2e annually).[82] These efforts, supported by partnerships like those with AIMS APAC REIT for 10.8 MWp solar (avoiding 5,900 tCO2e yearly), underscore SP Group's role in bridging grid reliability with decarbonization.[85]Renewable Energy and International Projects
SP Group offers renewable energy solutions in Singapore, including solar photovoltaic (PV) systems, wind energy, and battery energy storage, which are integrated with digital platforms for optimized management and grid stability.[85] These initiatives support the integration of intermittent renewables into the national grid, aligning with broader sustainability goals through low-carbon technologies.[86] Internationally, SP Group has pursued significant investments in solar projects, primarily in China and Vietnam, to expand its renewable portfolio. In May 2024, it committed over S$76 million (RMB 400 million) to develop a 90-megawatt (MW) aquavoltaic farm in Shandong Province, China, spanning 300 acres and linked to a hydrogen production facility; the project is projected to generate 162 million kilowatt-hours (kWh) annually while reducing carbon dioxide emissions by 160,000 tons per year.[87] In September 2024, SP Group deployed its largest solar initiative to date—a 240-megawatt-peak (MWp) agrivoltaic project in Guangdong Province—combining solar generation with agricultural use to maximize land efficiency.[59] Additional expansions include acquiring up to 150 MWp of rooftop PV assets from Shanghai Unisun New Energy Co. Ltd. and forming a joint venture with Jinko Power Technology Co. Ltd. to acquire further renewable assets across China.[60][43] In Vietnam, SP Group holds majority ownership in four solar plants totaling 165 MWp capacity, contributing to the country's clean energy expansion despite regulatory shifts affecting project viability.[88] It has also signed a memorandum of understanding (MOU) with BCG Energy to jointly invest in additional solar projects, aiming to bolster Vietnam's electricity supply and renewable integration.[46] Through its joint venture Sustainable Smart Energy Solutions (SSES), SP Group secured a contract in August 2025 to operate an integrated energy system at China's Chongqing transport hub, incorporating sustainable elements for high-speed rail infrastructure.[44] These overseas efforts reflect SP Group's strategy to leverage expertise in grid management for renewable deployment in Asia-Pacific markets.[62]Performance and Economic Impact
Reliability and Efficiency Metrics
SP Group's electricity network reliability is measured primarily through the System Average Interruption Duration Index (SAIDI), which averaged 0.15 minutes per customer in FY2023/24, equivalent to less than 9 seconds of outage annually.[89] This performance reflects sustained investments in grid hardening and predictive maintenance, maintaining outages at levels far below international benchmarks for urban networks. In FY2024/25, SAIDI rose slightly to 0.236 minutes for electricity, potentially attributable to increased demand pressures and integration of variable renewables, though still indicative of exceptional reliability.[82] For gas networks, SAIDI stood at 0.0671 minutes in FY2023/24 and 0.2579 minutes in FY2024/25, underscoring comparable robustness in supply continuity despite higher volatility in gas infrastructure exposure to external factors like pipeline integrity.[89][82] The System Average Interruption Frequency Index (SAIFI) data, which tracks interruption events, is not publicly detailed in recent reports but historically aligns with low single-digit incidents per thousand customers, supporting overall system resilience. These metrics, regulated by the Energy Market Authority, demonstrate SP Group's operational discipline in a high-density urban environment prone to faults from construction and weather. Efficiency metrics highlight minimal technical losses in transmission and distribution, which accounted for 83% of SP Group's Scope 1 and 2 greenhouse gas emissions (467,430 tCO₂e total) in FY2023/24, primarily from dissipated energy in electricity and gas lines.[89] By FY2024/25, these losses drove 92% of reduced Scope 1 and 2 emissions (432,321 tCO₂e total), with emission intensity falling 10.8% year-over-year to 8 kgCO₂e/MWh through targeted grid optimizations and smarter routing.[82] Singapore's broader electric power losses have historically hovered around 2%, enabling high throughput efficiency in SP's monopoly-managed infrastructure. Ancillary efficiency gains include customer-facing initiatives that avoided 717,426 tCO₂e in FY2023/24 via low-carbon tech adoption, amplifying network utilization without proportional capacity expansions.[89]| Metric | FY2023/24 | FY2024/25 | Notes |
