Combined Cycle plant (CCGT) in Thailand
Hin Kong Power Company, a newly created independent power producer (IPP) in Thailand, has awarded Mitsubishi Power a full turnkey contract for engineering, procurement and construction of a natural gas-fired 1,400MW combined cycle facility.
The facility will be powered by two M701JAC MW combined cycle units each designed around one 441,000kW gas turbine generator, unfired heat recovery steam generator, and 208,300kW steam turbine.
This contract also includes a 25-year Long Term Service Agreement (LTSA) for scheduled and unscheduled gas turbine maintenance. Commercial operation is scheduled to begin in March 2024 for the first unit, with full operation by January 2025.
With both combined cycle units operating, the facility is rated at 650,000kW net plant output and 64.0% net efficiency running on pipeline natural gas fuel.
The CCGT facility will be built approximately 100 kilometers west of Bangkok. All of its generated power will be sold to the Electricity Generating Authority of Thailand under a long-term power purchase agreement (PPA).
While the majority (63%) of Thailand’s electricity is produced by gas, the country still relies on coal for 19% of its generating capacity. Compared to conventional coal-fired plants, Mitsubishi says, the 1.4GW combined cycle facility (CCGT) in Thailand is expected to reduce CO2 emissions by 70% for an annual reduction of 7 million tons per year – due to lower emissions of natural gas fuel and higher combined cycle efficiencies at full and part-load output.s
