Pulau Indah is a 1.2GW combined cycle power plant (CCPP) located on Pulau Indah Island in Selangor, Malaysia.
It was developed and is operated by Pulau Indah Power Plant (PIPP), originally a joint venture between Maxim Global (formerly Tadmax Resources), Worldwide Holdings, and Korea Electric Power (KEPCO).
Recommended Buyers Guides
The project was awarded to Tadmax Resources by the Malaysian Government in August 2016, and the company received a letter of approval from the Energy Commission to develop the plant in September 2019.
The total cost of the power plant was RM3.35bn ($800m). A financing deal was signed in March 2021 with Bank Pembangunan Malaysia, Maybank Islamic, and United Overseas Bank (Malaysia) for the project.
Construction works started in May 2021, after PIPP received notice to proceed in January 2021.
In December 2022, Maxim Global sold its interest in the project to Worldwide Holdings. PIPP is now owned by Worldwide Holdings (75%) while the remaining 25% is held by KEPCO.
The power plant commenced commercial operations in March 2025, and it was officially inaugurated and became fully operational in September 2025.
The low-carbon electricity generated by the plant is fed to the national grid to help meet power demand in the Klang Valley. At full capacity, the plant generates enough electricity to supply approximately 2.5 million homes.
Location of the Pulau Indah CCPP
The project is located in Pulau Indah, approximately 60km from the Malaysian capital city, Kuala Lumpur.
It was constructed in a 60-acre area of reclaimed land adjacent to the Port Klang Free Zone.
Pulau Indah combined cycle power plant details
Pulau Indah combined-cycle power plant features a natural gas-fired CCPP with a net efficiency of approximately 62%, which is higher than that of coal and oil.
The project was implemented in five construction phases, which include design, engineering, procurement, construction, commissioning and testing.
The plant consists of two units of GE 9HA.01 600MW gas turbines, an STF-D650 steam turbine, a W88 generator, and a once-through heat recovery steam generator (HRSG).
The GE 9HA.01 is a 50Hz, four-stage gas turbine, featuring a double-wall casing, solidified blades, and an aerodynamic hot gas path.
The GE H-class gas turbines are air-cooled, have high efficiency and are cost-effective in converting fuel into electricity. The 50Hz gas turbine can generate up to 680MW with 63.7% net efficiency.
The HA units have fast start-up times to respond to fluctuating power demand and can burn fuel blends containing up to 50% hydrogen by volume mixed with natural gas.
The Pulau Indah power plant is also equipped with noise analysis and control technology to calculate the noise reduction effect of insulation materials.
Power purchase agreements
In August 2020, a 21-year power purchase agreement (PPA) was signed with Tenaga Nasional, a Malaysian electric utilities company.
The PPA, which became effective from the date of commissioning the power plant, expires in February 2046.
Contractors involved in Pulau Indah power project
A consortium comprising Posco Engineering & Construction (POSCO), Mitsubishi and PEC Powercon agreed to provide the engineering, procurement and construction (EPC) services for the project.
The EPC consortium contracted General Electric (GE) for the supply of power generation equipment, including gas turbines, for the project. Under a 21-year agreement, GE also provided maintenance services and software solutions for the power plant.
GE Global Parts & Products subcontracted Italy-based Flenco Fluid System to provide auxiliary systems for the power plant in March 2021.
Equator Engineering, along with POSCO, worked on the cost estimation of the power plant.
Malaysia-based logistics company Megalift was selected as the official project logistics service provider. Its first shipment was in October 2022, delivering 22 units of HRSGs. It also delivered its first gas turbine unit in March 2023.
The owner’s engineer services contract was awarded to Jacobs, an engineering and construction services provider, in December 2020. The contract included delivering technical advisory services for the design, construction, project management and financial closure of the power plant.
PetroVietnam Technical Services Corporation Quang Ngai, a provider of technical services in Vietnam, received the contract for the production and delivery of two exhaust diffuser ducts of the 9HA.01 gas turbine by GE in November 2021.
Singapore-based leading construction company Jurong Engineering was contracted to provide mechanical and piping services.
Petroliam Nasional was awarded a lateral gas line project, which includes providing a 42km pipeline to the power plant.
Jati Tinggi Group, a Malaysia-based company specialising in infrastructure, power and telecommunication cabling, was awarded the contract for the 500kV transmission line from the Pulau Indah power plant to the Olak Lempit substation in September 2021.
Other contractors and suppliers involved in the project are OKTECH and Minconsult.
