We are utilizing the abundant experience and high technological capabilities we have cultivated over many years through our development and management of coal and metal mines for hydroelectric and geothermal power generation. In relation to geothermal power generation, since Onuma Geothermal Power Plant (Akita Prefecture) started operation in 1974, we have played a central role in the construction and operation of Sumikawa Geothermal Power Plant (Akita Prefecture, operation started in 1995), Wasabizawa Geothermal Power Plant (Akita Prefecture, operation started in 2019), and Appi Geothermal Power Plant (Iwate Prefecture, operation to start in 2024).
We have been working on the "development and promotion of the use of renewable energies such as geothermal energy" and intend to engage in this project by making use of our experience and technological capabilities through investment to contribute to the success of the project.
Under our corporate philosophy of "For People, Society and the Earth," one of our Group's missions is to contribute to building a decarbonized society. To accomplish this mission, we will continue to work on the renewable energy business including geothermal power generation.
