Solar Power Plant and Solar Sharing

The GPSS Group owns numerous solar power plants all over the country. We also have vast construction experience for special high voltage and large-scale power plants of 10 MW or more.
In addition, we are a member of the "Oshamambe Local Agribusiness Joint Venture", a industry-government-academia collaborated project that promotes Oshamambe's regional revitalization.
We are also striving to put more effort in utilizing solar sharing. For instance, developing Japan's first cacao cultivation besides a traditional grass field with solar sharing.

Geothermal Power Generation

We own and operate geothermal power plants in three locations, which are located in Miyagi, Oita, and Niigata in collaboration with the local communities. We are also proactively exploring different types of heat generators other than geothermal heat to effectively utilize the thermal heat without any waste. For example, we introduced Sanko Binary Power Plant, a binary power generator that utilizes industrial waste heat.
Further we are partnering with overseas companies with advanced technologies as the importer to offer cost-efficiency and reduced lead time for our potential clients in the geothermal industry.

[Consulting] "HT GEST", Cutting-edge water treatment & digestate liquid concentration technology

HT GEST, a cutting-edge technology from Italy that is known for offering an effortless solution for all digestate after fermentation, which has been a significant hindrance to the popularization of biogas power generation. This technology produces two types of liquid after the solid-liquid separation: (1) "RO membrane permeate", which is cleaner and more transparent than river water that does not have any negative impact when it's mouthed into rivers, and (2) "liquid fertilizer", that has almost no solids or odor and is richer in fertilizer components. Most importantly, it is inevitably cost-efficient and sustainable than throwing away digestate every time.
