Mitsubishi Power Receives Full-Turnkey Contract to Build Three Gas Turbine Combined Cycle (GTCC) Power Plants with a Total Output of 1,950MW Natural Gas-Fired M701JAC Turbines in Sodegaura City, Chiba Prefecture
-- A Full-Scope Long-Term Service Agreem

· Chiba-Sodegaura Power Co., Ltd., a Special Purpose Company in which TOKYO GAS CO.,LTD is investing, is scheduled to commence commercial operations in FY2029
· Gas turbines capable of hydrogen co-firing will be supplied and the plant will be designed so that it can be converted to 100% hydrogen firing with minimal rebuilding in preparation for future decarbonization

Tokyo, July 21, 2023 - Mitsubishi Power, a power solutions brand of Mitsubishi Heavy Industries, Ltd. (MHI), has received a full-turnkey contract from Chiba-Sodegaura Power Co., Ltd., a company in which TOKYO GAS CO.,LTD is investing, for a project to build three gas turbine combined cycle (GTCC) power plants with 650MW class natural gas-fired units in Sodegaura City, Chiba Prefecture. A full-scope long-term service agreement (LTSA) was also signed. Commercial operation will commence successively from the 2029 fiscal year, and Mitsubishi Power will thereafter provide support for businesses in providing reliable power supplies through its full-scope LTSA.

The gas turbines that will generate the bulk of the power will be M701JAC gas turbines, a cutting-edge, high-performance model, according to the construction plan, which has been designed to achieve minimal environmental impact.

This project is a joint venture between MHI and Mitsubishi Electric Corporation, and covers EPC (engineering, procurement and construction). The two companies will collaborate on this project, with MHI supplying gas turbines, steam turbines, heat recovery steam generators and selective catalytic reduction (SCR) systems and Mitsubishi Electric supplying generators and electrical products.

Future decarbonization will be considered from the construction stage: gas turbines capable of hydrogen co-firing will be supplied, and the plant will be designed so that it can be converted to 100% hydrogen firing with minimal rebuilding.

With decarbonization set to take place in the near future, Mitsubishi Power is working on the development of various technologies to provide support for reliable power supplies, both in Japan and overseas. Through this project, Mitsubishi Power will help to alleviate the power supply reliability issues that have occurred during Japan's high-load periods in recent years, and will be a global pioneer in hydrogen power generation, one of the keys to zero-carbon energy.
