GE turbines are now powering Edra Energy’s combined cycle plant in Alor Gajah, Malacca, Malaysia.

The largest combined cycle power plant in the country adds more than 2.2 GW of electricity to Malaysia’s grid, which represents the approximate amount needed to power up to 10% of the country’s current demand. Edra is Malaysia’s second-largest independent power producer.

The new plant includes three generating blocks capable of generating over 745 MW per block. Each includes a GE 9HA.02 gas turbine, a STF-D650 steam turbine, a W88 generator and a Heat Recovery Steam Generator (HRSG).

The plant is controlled by GE’s Mark VIe integrated Plant Control System. GE will also provide its asset performance management (APM) digital solutions and manage all aspects of the project’s lifecycle.

The Alor Gajah plant’s equipment is part of the fleet monitored by GE’s Monitoring & Diagnostics (M&D) Center in Kuala Lumpur.

GE has been a player in Malaysia for nearly 40 years. The company has built a recent relationship with Edra, maintaining and servicing gas turbines installed at Telok Gong 1, Tanjong Kling and Kuala Langat power plants. Collectively, these facilities have a combined output capacity of 1.4 GW powered by GE’s E-class technology.

In February 2021, the 1,440 MW Track 4A Power Plant started generating in Pasir Gudang, Johor. The plant featured GE’s first 9HA.02 combined cycle gas turbine plants in commercial operation. It includes two generating blocks, each equipped with the gas turbine, steam turbine, a generator and a HRSG from GE. The plant is owned by Southern Power Generation.

According to GE, its 9HA.02 can now be quoted at 64.1% net efficiency in specified conditions with total output of 838 MW in 1×1 combined cycle configuration. The company also said its 9HA turbines are capable of firing hydrogen at a 50% mix.

According to Energy Watch’s current projections, Malaysia’s electricity demand is expected to grow from approximately 18.8 GW in 2020 to over 24 GW by 2039. The country’s energy transition objectives include plans to phase out of coal-fired power generation, with expected 7 GW of coal power to be retired by 2033, leading to a notable increase in other energy sources including gas, as reported by IHS Markit Research.
