The Pulau Indah power plant is a combined-cycle power plant (CCPP) being built on the island of Pulau Indah in Selangor, Malaysia.

The plant will generate 1.2GW of low-carbon electricity and will be connected to the national grid upon its completion to serve the power demand in the Klang Valley.

The Pulau Indah Power Plant (PIPP) consortium, previously known as Tadmax Indah Power, will own, construct and operate the power plant. PPIP comprises Worldwide (75%) and Korea Electric Power (KEPCO, 25%).

In August 2016, the Malaysian Government awarded the project to Tadmax Resources, which received a letter of approval from the energy commission to develop the project in September 2019.

The project received notice to proceed (NTP) in January 2021 while construction works commenced in May 2021. The project is expected to be commissioned in January 2024.

Location of the Pulau Indah CCPP

The project is located in Pulau Indah, approximately 60km from the Malaysian capital city, Kuala Lumpur. It is being constructed in a 60-acre (24ha) area of reclaimed land adjacent to the Port Klang Free Zone.

Pulau Indah power plant details

The project will feature a natural gas-fired CCPP with a net efficiency of approximately 62%, which is higher than that of coal and oil.

The project is being implemented in five construction phases, which include design, engineering, procurement, construction, commissioning and testing.

The plant will consist 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 (OT 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 Pulau Indah power plant will also be equipped with noise analysis and control technology to calculate the noise reduction effect of insulation materials.

Financing for the Pulau Indah power plant

The total cost of the power plant is estimated to be MYR3.35bn ($800m).

A financing deal was signed in March 2021 with Bank Pembangunan Malaysia, Maybank Islamic, and United Overseas Bank (Malaysia) for the project.

Power purchase agreements

A power purchase agreement (PPA) was signed with Tenaga Nasional (TNB), a Malaysian electric utilities company, in August 2020. The 21-year agreement will be effective from the date of commissioning the power plant.

Contractors involved in Pulau Indah power project

The consortium comprising Posco Engineering & Construction (POSCO), Mitsubishi and PEC Powercon will 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 for the project. GE also signed a 21-year services agreement in March 2021 to provide a wide range of service 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 heat recovery steam generators (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 includes delivering technical advisory services for the design, construction, project management and financial closure of the power plant.

PetroVietnam Technical Services Corporation (PTSC) 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 will be responsible for the mechanical and piping services of the project.

Petroliam Nasional (PETRONAS) was awarded a lateral gas line project, which includes providing a 42km pipeline to the power plant.

Jati Tinggi Group, a Malaysian-based company 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.
