The Keppel Sakra cogeneration plant is a 600MW combined-cycle gas turbine (CCGT) power plant developed in Singapore. It is the country’s first energy-efficient plant with superior performance and higher operational capacity.
Keppel Sakra Cogen (KSC) and Keppel Energy developed the project on a turnkey basis with an investment of approximately S$750m ($536.8m). The project was 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, 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 commenced operations in May 2026.
The project is part of Singapore’s international climate commitment towards 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.
The Keppel Sakra cogeneration plant emits substantially less CO₂ than the Singapore average for natural gas-fired generation, producing the same amount of electricity and avoiding more than six million tonnes of CO₂ over its service life.
Location
The Keppel Sakra cogeneration plant is located in the Sakra sector of Jurong Island, Singapore.
Keppel Sakra cogeneration plant details
The 600MW Keppel Sakra cogeneration plant is equipped with Mitsubishi Heavy Industries’ M701 JAC gas turbine, specifically designed to seamlessly integrate with hydrogen fuel. The turbine can operate with natural gas as the primary fuel, with the capacity to operate with 30% hydrogen.
Installed in November 2024, the high-efficiency gas turbine incorporates contemporary aerodynamics, cooling configurations and material technologies. It boasts the highest efficiency rating, exceeding 64%, and can transition to 100% hydrogen-fuelled operation.
The plant also features 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 steam produced by the plant can be used in industrial processes for energy and chemical customers on Jurong Island.
Infrastructure details
The Keppel Sakra cogeneration plant comprises 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 Keppel Sakra cogeneration plant’s power generation capacity for more than 15 years from the start of operations.
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 plant in August 2022.
Jurong Engineering provided the construction and balance of plant equipment.
Mitsubishi Power supplied major plant equipment including its J-class gas turbine, which was manufactured at its facility in Takasago, Japan. It is also providing long-term service for major maintenance of the CCGT power plant.
John Cockerill supplied the heat recovery boiler for the project. It was 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.
