Singapore’s Energy Market Authority (EMA) has awarded Tuas Power the right to build, own and operate a 670MW combined cycle gas turbine (CCGT) plant at Tuas Power Station. The facility is scheduled to commence commercial operations by December 2031 and is expected to supply enough electricity to power around 1.2 million four-room HDB households annually. The plant is expected to cost between SGD700 million and SGD1 billion, subject to the final tender outcome.
The plant will be capable of operating with up to 30% hydrogen blended with natural gas, while retaining diesel as a backup fuel. The CCGT unit will be developed as part of Singapore’s requirement for new and repowered gas plants to achieve higher efficiency and hydrogen compatibility. The project will replace ageing generation capacity and provide additional electricity supply for rising demand from energy-intensive sectors.
The award follows EMA’s April 2026 call for up to three new hydrogen-compatible plants for commissioning in 2031–2032. With the Tuas Power project, Singapore is expected to have at least 11 hydrogen-ready gas plants by 2032, including four completed in 2025. EMA forecasts peak electricity demand to grow by 2.4–4.8 per cent annually, reaching 9.6–11.4 GW by 2031, compared with around 8GW in 2025. Demand growth is being driven primarily by data centres and semiconductor manufacturing.
