Mitsubishi Power started operation of the first M701JAC unit at a natural gas-fired power plant project in Rayong Province, Thailand--marking the completion of the fifth of eight M701JAC gas turbines to be delivered as part of a full turnkey 5300MW contract.

The Rayong plant is owned and operated by Gulf PD, a joint venture project by Gulf Energy Development PCL, one of the largest independent power producers in Thailand, and Mitsui & Co., Ltd. Power generated at these plants will be sold to Thailand’s state power company Electricity Generating Authority of Thailand (EGAT), contributing to more reliable and efficient energy production in Thailand.

Mitsubishi Power has delivered five of the gas turbines within the contract delivery period, and the two plants are expected to be in commercial operation by October 2024. All four units of the Chonburi power plant commenced commercial operation in October 2022 and have exceeded 25 000 actual operating hours (AOH), demonstrating the reliability of the JAC gas turbines.

The overall project encompasses two GTCC power generation plants, each with four power trains comprising a gas turbine, steam turbine, heat recovery steam generator, and generator. Despite the disruptions caused by the COVID-19 pandemic during the peak construction period, the project has progressed in line with the initial schedule as a result of the close collaboration, ingenuity and efforts of everyone concerned.

“The successful delivery of the first unit within the contract period is a testament to the collective expertise gained during the construction of the Chonburi power plant, and the unwavering commitment of Gulf Energy Development, Mitsubishi Power, and all involved parties to work together as a unified team,” said Ryo Takubo, President and Managing Director of Mitsubishi Power, Thailand. “As we move forward with the remaining units, we will continue to work closely with our partners to contribute to the supply of stable power for the people of Thailand.”

Moving forward, Mitsubishi Power will continue its effort to complete the Rayong power plant, while also focusing on further promoting the widespread adoption of JAC Series gas turbines in order to ensure the stability of electric power essential for economic development around the world, and contribute towards reducing the environmental impact of power generation.
