Thai Power Plant Goes Online with Mitsubishi Power’s Final Turbine Installation

Mitsubishi Power successfully completed the engineering, procurement, and construction (EPC) work for Hin Kong Power’s 1,400-MW natural gas-fired gas turbine combined-cycle (GTCC) power plant near Bangkok, Thailand. The EPC completion was marked by the second M701 JAC gas turbine entering commercial operation, with the previous turbine coming online in March 2024. Hin Kong Power’s GTCC plant obtained full capacity on schedule.

"This project marks the commercial operation of our tenth M701 JAC gas turbine in Thailand, a milestone that we are proud to celebrate together with RATCH and Gulf Energy Development,” said Takao Tsukui, Executive Vice President, Mitsubishi Power. “Looking ahead, we remain committed to providing continuous support through the 25-year agreement, ensuring the stable operation of this power plant over the years to come. Building on the success of the Hin Kong Power project, we are eager to further strengthen our partnership and embark on new challenges together."

The facility will generate and deliver power to the Electricity Generating Authority of Thailand, and, under a 25-year long-term service agreement, Mitsubishi Power will provide turbine maintenance. These aspects are expected to secure high-efficiency, reliable electricity to support Thailand’s growing power demand. Hin Kong Power is a joint venture established by RATCH Group and Gulf Energy Development (GULF).

"We are proud to celebrate the completion of this high-efficiency power plant, which furthers our goal to deliver reliable, sustainable, and efficient energy solutions for Thailand,” said Nitus Voraphonpiput, Chief Executive Officer, RATCH. “This plant supports the growing energy demands of the country while ensuring we are future ready as energy needs evolve. We look forward to strengthening collaboration with our partners to drive Thailand's energy progress."

JAC Turbines in Thailand

Mitsubishi Power’s JAC gas turbine has a combined-cycle efficiency over 64%, featuring operational flexibility, quicker start-up times, and load-following capability. These turbines can balance power demand for grids penetrated by large amounts of intermittent renewable energy sources—they also satisfy standards for reducing CO₂ emissions. With this latest project, Mitsubishi Power has supplied 22 gas turbines to RATCH and GULF projects, delivering more than 14,000 MW of power generation capacity in Thailand.

"The on-schedule completion and smooth operation of the plant underscores strong synergy between GULF, RATCH, and Mitsubishi Power,” said Chaichawin Tantiyankul, Executive Officer, GULF. “This project plays a significant role in strengthening Thailand's energy security and supporting economic growth. We are confident that this partnership will continue to drive innovative and efficient energy solutions."

In early December 2024, the Grand River Dam Authority (GRDA) selected Primoris Services Corp. to perform the mechanical construction of Unit 4 at the Grand River Energy Center (GREC) in Chouteau, OK. Unit 4 will feature a 426-MW Mitsubishi 501 JAC gas turbine with the largest selective catalytic reduction system to reduce NOx emissions and adhere to environmental regulations.

GREC will use simple-cycle technology to replace its final coal-fired unit and supplement wind power production for GRDA’s intermittent grid. Simple-cycle power plants, such as GREC, can support renewable energy through fast-start/stop capabilities during peak load times, reducing fossil-fuel reliance and stabilizing the grid.
