Mitsubishi Power Starts M701 JAC Operation at GTCC Power Plant

Published on: 

The M701 J-series air-cooled (JAC) gas turbine is installed on the third unit at one of Gulf PD Co.’s natural gas-fired power plants in Rayong, Thailand.

Mitsubishi Power completed the construction and began operations for an M701 JAC gas turbine at Unit 3 of a gas turbine combined-cycle (GTCC) power plant in Thailand’s Rayong province. The power plant is a joint venture between Gulf Energy Development PCL and Mitsui & Co., with Gulf PD Co. serving as the operator of the plant located approximately 130 km southeast of Bangkok. The project consists of two GTCC power plants, each equipped with four gas turbine units, generators, steam turbines, and heat recovery steam generators.

The company has now successfully delivered seven of eight M701 JAC units across the two large-scale 2,650 MW GTCC power plants in Rayong and Chonburi, comprising a collective output of 5,300 MW. Rayong and Chonburi are expected to be fully operational by fall 2024, with all eight gas turbine units supporting the electricity needs of industrial and economic hubs in eastern Thailand.


"Having been part of Thailand's energy story for more than five decades, we are honored that our robust GTCC solutions have helped to enhance the reliability and efficiency of Thailand's energy infrastructure and supported the country's progress towards a more sustainable energy future,” said Akira Takahashi, President and Managing Director of Mitsubishi Power (Thailand) Ltd. “In cooperation with Gulf and valued partners, we aim to complete this project, and will continue to do our best to support long-term maintenance and services."

Six currently installed units across the Gulf Sriracha power plant (Chonburi) and the Rayong plant have demonstrated smooth operation, with a total accumulation exceeding 75,000 actual operating hours. Also in Thailand, Mitsubishi Power started operations on one of two M701 JAC gas turbines in Hin Kong Power Co.’s 1,400 MW natural gas-fired power plant. For the second unit, completion and full operation is slated for January 2025.

Mitsubishi Power completed an additional GTCC equipment supply in early April 2024. The Hongkong Electric Company (HK Electric) placed an order with Mitsubishi Power for natural-gas-fired GTCC power generation system equipment for Lamma Power Station’s 380 MW Unit 13, which is scheduled to begin operation in early 2029. Mitsubishi Power previously completed GTCC equipment orders for Units 10, 11, and 12 in July 2015.

The company will manufacture and supply its M701F gas turbine, a steam turbine, a heat recovery steam generator (HRSG), and a selective catalytic reduction system. The HRSG will be manufactured by Mitsubishi Generator Co.—a new company in the Hyogo Ward of Kobe City, Japan, formed on April 1 through an integration of the power-generator systems businesses of Mitsubishi Heavy Industries and Mitsubishi Electric.

“HK Electric is one of Hong Kong's leading power providers and the sole electricity provider to Hong Kong Island and Lamma Island,” said a representative of HK Electric. “Mitsubishi Power has had business relations with HK Electric for many years, having delivered numerous power generation system core components—including gas turbines, steam turbines and boilers—for the Lamma Power Station. It can be said that this latest order also reflects our assessment of the performance and proven track record of Mitsubishi Power products.”
