Shizen Energy’s solar capacity contracted under PPAs with Microsoft has reached 100MW across four projects including two operational, the company announced on October 3, 2025.
According to the statement, following their first 20-year virtual PPA for the 25MWAC/31MWDC Inuyama solar plant commissioned in Aichi Prefecture in February 2024, which was also Microsoft’s first deal in the country, the developer and the technology company signed three additional agreements for projects in Kyushu and Chugoku. One of those, an undisclosed power plant in Kyushu, is already online. The remaining two are under construction.
Shizen Energy said that its wholly-owned subsidiary Shizen Engineering is handling engineering, procurement, and construction (EPC) of one of the two under-construction projects. Its operations and asset management unit Shizen Operations will operate all of the power plants.
The company did not disclose further details on location or capacity. METI data indicates the contracted projects may include a 25.9MWAC/36.3MWDC one in Shimane Prefecture and a 20MWAC/30MWDC one in Oita Prefecture, both of which were awarded 7.94 yen per kWh feed-in-premium (FIP) contracts in Japan’s 18th Solar Auction through special purpose companies (SPCs) affiliated with the developer.
Microsoft currently operates two data centers in Japan, including one in Saitama Prefecture and one in Osaka Prefecture. In April 2024, it announced plans to invest $2.9 billion over two years to expand its cloud computing and AI infrastructure in the country.
Japan Energy Hub’s PPA database shows Shizen Energy has also signed a 20MWAC/30MWDC virtual PPA with Google among other deals.
