Mitsubishi Power, a power industry brand of MHI, has commenced operations of a third M701JAC gas turbine unit installed at a Gulf SRC plant in Chonburi Province, Thailand. It is the third of eight such GTs destined for a project to build two natural gas-fired power plants in the country. The unit was inaugurated on 31 March, as part of a joint venture of Gulf Energy Development Public Company Ltd, one of Thailand's largest independent power producers, and Mitsui & Co. The first unit, which was also the first M701JAC in Southeast Asia, started commercial operations at the end of March 2021. The first and second units have been in commercial operation for one year and six months respectively.
This M701JAC joins the global fleet of J-Series and JAC-Series gas turbines that have amassed over 1.6 million operating hours; with 83 units ordered across the globe. When completed, the eight units in the project will form a gas turbine combined cycle (GTCC) power system with a total output of 5300 MW. A 25-year long-term service agreement (LTSA) for these units is also in effect. Mitsubishi Power is providing support for the customer's operation and maintenance of the three units through remote monitoring of operations with TOMONI – its suite of intelligent solutions that includes an analytical platform which helps optimise power plant operations. Construction of the remaining five units has commenced and will be completed in 2024 when the final unit starts up commercially.
The two large-scale power plants are under construction in Chonburi and Rayong provinces, approximately 130 km southeast of Bangkok. Each 2.650 GW plant will fire 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 output will be sold to the Electricity Generating Authority of Thailand (EGAT.
