Japan sits on a rich and renewable resource: hot water. We build power plants that harness the energy in hot water and convert it into electricity.
From north to South
Some of our plants are built around new wells, others will use existing wells where the water is not hot enough for traditional geothermal power plants, and still others take advantage of unused low-temperature heat in what’s called the “bottoming cycle” of a traditional geothermal power plant.
Kitsune Power Plant, Okuhida, Gifu
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 Power Plant, Oguni, Kumamoto
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 Power Plant, Oguni, Kumamoto
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 (manufactured by Climeon) 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.
Baseload Power Japan is benefits from the knowledge and experience gleaned from other Baseload Power companies throughout the world. Here are their projects.
Three Icelandic businessmen saw the potential in converting low-temperature heat into electricity, and in January 2018, we acquired a stake in their company, Varmaorka.
During the fall of 2018, Baseload Capital founded its first official subsidiary in Japan.
During the fall of 2019, we founded our second subsidiary, Baseload Power Taiwan.
In February 2018, we signed an agreement with Wendel Energy Operations I in California to structure a debt facility to finance the repowering of their existing geothermal plant.
Does it make a difference if you get your power from coal or geothermal heat? We asked our local partners and community members what they think.
