Shizen Energy has finalised renewable energy purchase agreements (REPAs) with Microsoft for four solar projects in Japan, reaching a total contracted capacity of 100 MW. The agreements follow Microsoft’s initial deal for the Inuyama solar power plant, following which three additional 20-year contracts have since been signed.
The solar projects are situated across the Kyushu and Chugoku regions. All projects have achieved financial close, with one project in Kyushu already operational. The remaining projects are under construction, including one being built by Shizen Engineering Inc., a wholly owned engineering, procurement, and construction subsidiary of Shizen Energy. All four projects will be managed and operated by Shizen Energy’s asset management subsidiary, Shizen Operations Inc.
In May 2025, Microsoft entered into a long-term power purchase agreement (PPA) with Clearway Energy Group for the 335 MW Mount Storm wind farm in West Virginia. This project will help Microsoft meet its sustainability and decarbonisation targets by supplying carbon-free energy.
In April 2025, Shizen Energy and Tokyu Land Corporation established a joint venture, ReENE Shizen Farm LLC, to develop agrivoltaic power generation projects. Its first initiative involves a 708.48 kW vertical solar power plant at Obihiro University of Agriculture and Veterinary Medicine, supplying electricity to the university.
REGlobal’s Views: Microsoft like other large tech corporates aims to reduce its carbon emissions globally. It is procuring large volumes of renewable energy to match these targets and offset emissions across different markets. It is already a large corporate purchaser of renewable power and this recent offtake arrangement will help the company to move closer to its net zero goals.
