JERA Co., Inc., ENEOS Power Corporation, and Kyushu Electric Power Company, through their joint venture Goi United Generation LLC, have been progressing with the replacement work at the Goi Thermal Power Station. They are pleased to announce that Unit 1 of the Goi Thermal Power Station has officially commenced commercial operation as of August 1, 2024.

This new unit employs a cutting-edge LNG-fired gas turbine combined cycle (GTCC) system, which is designed to offer advanced power generation capabilities. With a substantial generating capacity of 780 MW, it is expected to play a key role in ensuring a stable and reliable electricity supply. The innovative design of this thermal power plant not only enhances efficiency but also addresses environmental concerns by significantly reducing CO2 emissions.

The Goi Thermal Power Station Unit 1 represents a significant step forward in the modernization of power infrastructure, showcasing world-leading efficiency in power generation. This advancement aligns with the commitment of JERA and its partners to advance state-of-the-art technologies and foster environmental sustainability.

The three companies remain dedicated to continuing the implementation of cutting-edge replacement projects at the Goi Thermal Power Station, aiming to further enhance the station's performance and environmental footprint. Their ongoing efforts reflect a strong commitment to both operational excellence and sustainable energy solutions.
