RENEWABLE HEAT AND
POWER. ALWAYS ON.

Unlocking Japan’s geothermal energy potential for resilience and growth.

Who we are

At Baseload Power Japan, we develop geothermal heat and power plants to support the local communities around them. Geothermal energy is renewable and always on, 24/7. We call it homegrown energy.

Not only are geothermal power plants resilient in the face of disasters, but they can also revitalize local communities by providing clean electricity and a stable supply of hot water. This enables self-sustainable businesses, jobs and tourism.

Our success relies on strong local partnerships and the international network of long-term, committed partners that we are a part of. We facilitate connections between the Japanese geothermal industry and global supply chains, know-how and investors, backed by our parent company Baseload Capital in Sweden.

Japan has the third-largest geothermal potential in the world, a resource we aim to unlock. Utilizing both domestic and international expertise, we are dedicated to improving the process of geothermal development and operations according to subsurface data, science and best practices.

We will work relentlessly, doing our part to help Japan meet its 2050 net-zero target as well as the geothermal energy target of 1,500 MW by 2030.

Our power plants

Kitsune

The hot spring binary power plant (output: 50 kilowatts) started operation in June 2020 in Okuhida Hot Spring Village. After using the hot water pumped up from the hot spring well to generate electricity, we supply it to the hot spring facility at a temperature suitable for bathing, which realizes the multiple use of energy. In addition, by combining power generation and bathing, hot water can be supplied to hot spring facilities with stability. The generated electricity is sold using FIT (feed-in-tariff).

Shika

The binary power plant (150 kilowatts) started operation in April 2020 as attached to the Waita geothermal power plant (output: 2 megawatts, flash system) operated by Furusato Netsuden in Oguni-cho, Aso-gun, Kumamoto Prefecture. This is our first geothermal power plant, and we use it to generate electricity using secondary water before returning it to the ground (bottoming cycle power generation). We realize the efficiency of power generation by reusing it.

Sansui

Baseload Power Japan in collaboration with Furusato Power generation and Ryokan Sansui began operations of 99 kW in 2022. The plants generate electricity by utilizing steam from an existing hot spring well to turn turbines at two locations. The annual power generation is estimated at 700 MWh, which is equivalent to the annual power consumption of roughly 200 households. The surplus of hot water, both hot spring water from the source and water from condensed steam used in the power generation process, are provided to Ryokan Sansui to be utilized as bath water.
