Mitsubishi Power, a power solutions brand of MHI, on 1 October commenced operation of the fourth and final M701JAC unit at an ultra-large-scale natural gas-fired power plant in Chonburi Province, Thailand. The plant is owned by a joint venture of Gulf Energy Development PCL, one of the largest independent power producers in Thailand, and Mitsui & Co Ltd.
The start of full operations signals the completion of one of two gas turbine combined cycle power plants in Thailand under full turnkey orders for construction secured by Mitsubishi Power in 2018. Construction of the second power plant project is currently underway in Rayong Province.??
The Chonburi power plant is located approximately 130 km southeast of Bangkok. The first unit has already been in commercial operation for one and a half years, the second unit for one year, and the third unit for six months.
In September 2022, the M701JAC gas turbine of the first unit achieved 8000 actual operating hours (AOH), establishing what is said to be an industry benchmark for reliability.??
The GTCC power generation equipment in this project consists of four power trains per power plant, each made up of four subsystems: a M701JAC gas turbine, steam turbine, heat recovery steam generator, and generator.
