The Keppel Sakra Cogeneration Plant (KSC Plant) is a 600MW combined-cycle gas turbine (CCGT) power plant being developed in Singapore.
Keppel Sakra Cogen (KSC) and Keppel Energy are developing the project on a turnkey basis with an investment of approximately S$750m ($536.8m). The project is being developed based on Keppel’s asset-light business model.
Recommended Buyers Guides
It is owned by KSC, in which Keppel Infrastructure’s wholly owned subsidiaries, Keppel Asia Infrastructure Fund and Keppel Energy, will hold 70% and 30% equity interests, respectively.
The final investment decision on the project was taken in August 2022, and the groundbreaking ceremony was held in July 2023.
The combined-cycle gas turbine plant is scheduled to begin operations in the first half of 2026 (H1 2026).
The project is part of Singapore’s international climate commitment to decarbonisation and support for achieving net-zero emissions by 2050. It is also aligned with Keppel’s Vision 2030, in which the company’s strategy focuses on sustainability.
Once operational, the Keppel Sakra Cogen Plant is expected to emit substantially less CO₂ than the Singapore average for natural gas-fired generation, producing the same amount of electricity, avoiding more than six million tonnes of CO₂ over its service life.
Location
The KSC Plant is being developed in the Sakra sector of Jurong Island, Singapore.
KSC Plant details
The 600MW KSC Plant will initially operate with natural gas as the primary fuel, with the capacity to operate with 30% hydrogen.
It will be equipped with Mitsubishi Heavy Industries’ cutting-edge M701 JAC gas turbine, specifically designed to seamlessly integrate with hydrogen fuel.
In November 2024, Keppel installed the high-efficiency gas turbine, which incorporates contemporary aerodynamics, cooling configurations and material technologies.
The turbine boasts the highest efficiency rating, exceeding 64%, and can transition to 100% hydrogen-fuelled operation.
The plant will feature a single horizontal heat recovery steam generator (HRSG) equipped with stainless steel exchangers, designed to withstand ultra-high steam temperatures of 600°C and above.
The KSC Plant will also produce steam, which can be used in industrial processes for energy and chemical customers on Jurong Island. It will be Singapore’s first energy-efficient plant with superior performance and higher operational capacity.
Infrastructure details
The KSC Plant will comprise a main control building, which incorporates energy-efficient systems, on-site renewable generation and an integrated energy management framework.
In November 2024, the main control building obtained the Building and Construction Authority of Singapore’s Green Mark Zero Energy Certification, making it the first facility on Jurong Island to be granted this certification.
Power purchase agreement
In January 2024, Keppel signed a multi-year power purchase agreement with GlobalFoundries to offtake 25% of the KSC Plant’s power generation capacity for more than 15 years once the plant becomes operational.
Contractors involved
A consortium comprising Jurong Engineering and Mitsubishi Power Asia-Pacific was awarded the engineering, procurement and construction contract for the construction of the KSC Plant in August 2022.
Jurong Engineering is providing the construction and KSC’s balance of plant.
Mitsubishi Power is supplying major plant equipment, including its J-class gas turbine, which will be manufactured at its facility in Takasago, Japan. The latter will also provide long-term service for major maintenance of the CCGT power plant.
John Cockerill was awarded the contract to supply the heat recovery boiler for the project. It will be responsible for the design, erection and commissioning of the HRSG.
GreenA Consultants, a sustainability consultancy company, assisted Keppel in achieving the Green Mark Zero Energy Certification for the main control building.
