The Singapore data center market was valued at USD 3.25 billion in 2025 and is projected to reach USD 5.11 billion by 2031, growing at a compound annual growth rate (CAGR) of 7.83%. This expansion is driven by the country's strategic position as a key digital hub in Southeast Asia, renewed infrastructure development following the lifting of the data center construction moratorium in 2022, and strong demand from global hyperscale operators and regional enterprises. Despite land scarcity and rising power constraints, Singapore continues to attract major investments due to its stable regulatory environment, advanced digital infrastructure, and strong connectivity. The government’s commitment to sustainability under the Singapore Green Plan 2030 plays a central role in shaping the market. Key targets include reducing greenhouse gas emissions to around 60 million tons of CO2 equivalent by 2030 and achieving net-zero emissions by 2050. These goals are supported by initiatives to increase renewable energy adoption, improve energy efficiency, green 80% of buildings by 2030, and deploy at least 2 gigawatt-peak (GWp) of solar energy. As of 2025, Singapore has approximately 44 operational colocation data centers, with most built to Tier III standards. The wholesale colocation segment is the dominant revenue driver, accounting for 58.3% of total colocation revenue in 2025. This share is expected to grow to over 67.2% by 2030, reflecting strong enterprise demand for scalable, cloud-ready infrastructure. Significant investment activity is expected in the coming years. Total industry investment is projected to exceed USD 5.11 billion by 2031. A major development occurred in November 2025 when KKR and Singtel entered advanced talks to acquire over 80% of ST Telemedia Global Data Centres (STT GDC) in a deal valued at more than USD 5 billion. This transaction would consolidate one of Asia’s largest data center platforms, with 1.7 GW of capacity across 11 markets. In October 2025, Singapore announced the development of a 700 MW low-carbon data center park on Jurong Island. This landmark project will utilize hydrogen-ready power plants, expanded battery storage, ammonia energy, and solar integration to support sustainable, high-density data center growth. The average industrial electricity price in Singapore ranges from USD 0.21 to 0.24 per kWh, a key cost factor for data center operators. The market’s investment landscape is segmented across IT, power, cooling, and construction services, with growing demand for energy-efficient and AI-optimized infrastructure. Leading IT infrastructure providers such as NVIDIA, Quanta, and Wiwynn are supplying AI-ready hardware and rack-scale solutions. Support infrastructure providers including ABB, Eaton, Cummins, and Vertiv maintain strong local operations through maintenance contracts and regional manufacturing. Engineering firms are adopting modular and prefabricated construction methods to accelerate build timelines. Major operators in the market include Equinix, Digital Realty, AirTrunk, Keppel Data Centres, Singtel, and STT GDC, with new entrants like DayOne emerging. The market’s future is shaped by the convergence of AI-driven demand, sustainability mandates, and strategic public-private partnerships.
