According to the Ministry of the Environment’s Renewable Energy Potential System (REPOS), Hokkaido has a potential solar power installation capacity (land-based) of 337,471 MW *1, which is outstandingly high compared to other regions of Japan, and further development of renewable energy power plants is highly anticipated.

Shizen Energy has designed and promoted renewable energy development projects in Hokkaido to meet the various needs of its customers and partners, including local governments, the agriculture and livestock industry, academia, and other industrial sectors. The company supplies renewable energy to companies in Hokkaido under a corporate PPA and is conducting a joint demonstration project using a vertical solar power generation system installed on the grounds of Rakuno Gakuen University. 

The new company will seamlessly utilize Shizen Energy Group’s expertise to provide comprehensive decarbonization solutions such as decarbonization support services and decarbonization mobility services, maximizing Hokkaido’s renewable energy potential.

In particular, Shizen Energy will make maximum efforts to promote the stabilization and decarbonization of the livestock industry and agricultural businesses through the coexistence of renewable energy and agriculture, including a joint project with Rakuno Gakuen University which began in December 2023 to explore the possibility of symbiosis between renewable energy and agriculture by utilizing vertical solar panels.

Hokkaido Shizen Energy’s vision is to create Hokkaido’s future with the community through renewable energy while protecting Hokkaido’s remarkable nature. Hokkaido Shizen Energy will work with the community to promote a sustainable decarbonized society and envision Hokkaido’s future through decarbonization.
