Renewable Energy Business

Yuzawa Geothermal Power Corporation, which was jointly established with Electric Power Development Co., Ltd. and Mitsubishi Gas Chemical Co., Inc., commenced commercial operation of a large-scale geothermal power plant, the first of its capacity in Japan in 23 years, known as Wasabizawa Geothermal Power Plant in the Wasabizawa and Akinomiya areas of Yuzawa City, Akita Prefecture in May 2019.
Unlike photovoltaic or hydroelectric power, geothermal power is capable of providing a stable supply of electricity regardless of the weather and is the most anticipated form of power generation among renewable energy sources for curbing CO₂ emissions and providing a stable supply of electricity in Japan.
Having utilized our underground resource exploration technology, our Group has more than 40 years of experience in the geothermal development and power generation businesses.
As a Group, we will continue to utilize our core technologies to expand our geothermal power generation business.

In October 2014, we started an environmental study concerning a geothermal power project in the Appi area of Hachimantai City, Iwate Prefecture, and in October 2015, we jointly established Appi Geothermal Energy Corporation with Mitsubishi Gas Chemical Co., Inc.
Appi Geothermal Energy Corporation started the environmental impact assessment process in October 2015, received a verification notice of its environmental impact statement in January 2018 and completed public inspection of the statement in March of the same year. With the addition of Electric Power Development Co., Ltd. in June 2018, the three companies made changes to their systems to proceed with commercialization. Construction work began in August 2019, and started commercial operation of a 14,900kW geothermal power plant in March 2024.
