Hin Kong Power Plant
The Hin Kong Power Plant is a 1,400-megawatt combined-cycle gas turbine power station in Ratchaburi Province, Thailand. It is operated by Hin Kong Power Co., Ltd., a joint venture between RATCH Group Public Company Limited and Gulf Energy Development Public Company Limited. The plant supplies electricity to the Electricity Generating Authority of Thailand under a 25-year Power purchase agreement signed in 2019.
Location and background
The power plant is located in Hin Kong Subdistrict, Mueang Ratchaburi district, approximately 100 kilometres west of Bangkok. It was developed on the same site as the decommissioned Tri Energy Power Plant, which was retired after more than two decades of operation.Hin Kong Power Co., Ltd. was incorporated in 2019 under Hin Kong Power Holding Co., Ltd.. HKH is 51 percent owned by RATCH Group and 49 percent by Gulf Energy Development.
Design and technology
The facility uses two 700-megawatt M701JAC gas turbines supplied by Mitsubishi Power, arranged in a combined-cycle configuration. The turbines are air-cooled and use advanced combustion technology to achieve higher efficiency and lower emissions.The plant's total installed capacity is 1,400 megawatts. Electricity generated at Hin Kong is transmitted to the national grid via EGAT's 230-kV substation network.
Fuel supply
The plant operates on natural gas supplied through the national gas pipeline network operated by PTT Public Company Limited. Under Thailand's gas-market liberalization policy, Hin Kong Power Holding obtained a private LNG import license from the Energy Regulatory Commission, enabling direct procurement of liquefied natural gas for the project.Development and construction
The project's Environmental Impact Assessment was approved by Thailand's Office of Natural Resources and Environmental Policy and Planning in 2020. Construction was carried out by a consortium of Mitsubishi Power Co., Ltd., MHI Power Project Co., Ltd., and Sino-Thai Engineering and Construction Public Company Limited.The first 700 MW unit entered commercial operation in March 2024, followed by the second in January 2025. The plant contributes to Thailand's Power Development Plan 2018 objectives for energy reliability and cleaner gas-based generation.
