GTCC facility in Thailand

The first Mitsubishi Power M701JAC series gas turbine in southeast Asia has gone into commercial operation as part of a new gas-fired power plant in Thailand.

The newly inaugurated M701JAC joins the global fleet of J-Series and JAC-Series gas turbines that have amassed more than 1.3 million operating hours; with 83 units ordered across the globe. The project is part of a joint venture between Gulf Energy Development Public Company Limited, one of Thailand’s largest independent power producers (IPP), and Mitsui & Co., Ltd. The M701JAC is the first of eight units ordered on a full-turnkey basis in 2018 and is the first of its kind in Southeast Asia. These eight units will comprise gas turbine combined cycle (GTCC) systems with a total output of 5300 MW A 25-year long-term service agreement (LTSA) for these units is also in effect. The construction of the remaining seven units has commenced and is scheduled for full launch of commercial operations in 2024.

The two ultra-large-scale power plants are under construction in Chonburi and Rayong Provinces, approximately 130 km southeast of Bangkok. Each plant will have an output of 2650 MW and use natural gas as its primary fuel source, along with four power trains each incorporating a gas turbine, steam turbine, heat recovery steam generator and generator. Mitsubishi Power will manufacture and supply the gas and steam turbines as well as ancillary equipment, while Mitsubishi Electric Corporation will provide the generators. The power generated will be sold to the Electricity Generating Authority of Thailand (EGAT) to support providing the country with a reliable and highly efficient source of clean energy.

Thai CCGT plant puts first M701JAC gas turbine into operation.

The GTCC power generation equipment in this project consists of four lines per power plant, including four gas turbines, steam turbines, exhaust heat recovery boilers, and generators. Mitsubishi Power will manufacture and supply gas turbines, steam turbines, etc., and Mitsubishi Electric Corporation supplies generators.
