The Melaka power project is a 2.242GW gas-fired, combined-cycle power station under construction in the Alor Gajah District of Malaysia.
The project is being financed, developed, and will be operated by Edra Energy Power, an independent power producer owned by China General Nuclear Power Corporation (CGN, 63%) and China Southern Power Grid (CSG, 37%).
The main construction works on the £1.21bn ($1.5bn) gas-fired power project comprising three power blocks were started in the first quarter of 2018, with the start of commercial operations expected in the first half of 2021.
Location and site details
The Melaka combined-cycle gas turbine (CCGT) power project is located at Kuala Sungai Baru, approximately 25km north of Melaka, in the Alor Gajah District of Malaysia.
The project site lies approximately 90km to the southeast of Malaysia’s capital Kuala Lumpur.
Melaka combined-cycle power plant make-up
The Melaka power plant will comprise three combined-cycle blocks of capacity 747.7MW capacity each.
Each block will be equipped with a GE 9HA.02 gas turbine, a heat recovery steam generator (HRSG), and a steam turbine.
The gas turbine has a net power output of 571MW and offers a net efficiency of 64.1% in combined-cycle operation.
The GE 9HA.02 is a four-stage gas turbine that comes with a 3D aerodynamic hot gas path, single-crystal turbine blades, and a 14-stage advanced compressor with aerodynamic air-foils.
The other components of the project include a temporary jetty, a fabrication laydown, seawater intake system, a discharge stilling basin, a water treatment facility, a fuel gas system, and a 500kV switchyard.
The electricity generated by the Melaka combined-cycle power station will be evacuated into the grid through a 500kV power transmission line.
Power purchase agreement
Edra Energy Power Company signed a power purchase agreement (PPA) with Tenaga Nasional Berhad (TNB) in April 2017.
The electricity output of the plant will be sold to TNB for a period of 21 years from the date of commercial operations.
Hyundai Engineering bagged an engineering, procurement, and construction (EPC) contract worth approximately £996.78m ($1.28bn) for the Melaka gas-fired power project in May 2017, while General Electric (GE) was contracted for the supply of gas turbines and generators.
