Wind-Powered, Off-Grid Data Center Emerges as a New Model in Japan 

Toyota Tsusho and its renewable energy subsidiary, Eurus Energy Holdings, announced they will develop Soya Green Data Center I (tentative name), a 3 MW data center in Wakkanai, Hokkaido, adjacent to the Kabakaoka Wind Farm. This DC is scheduled to begin operations in 2027 and will be Japan’s first data center to be co-located with wind power and supplied directly via a private transmission line from the turbines, rather than via the grid, and supported by UPS to manage wind intermittency. Around 80% of power will come from the nearby wind farm, with the remaining 20% supplied as renewable electricity by Eurus Green Energy to achieve effectively 100% renewable use. Construction is planned for April 2026 with full operation in 2027. 

The wind farm began commercial operation in February 2024 and currently sells power under the FIT at JPY 18/kWh, but once supply to the data center starts, it is likely to shift away from FIT to a non-FIT scheme such as a PPA in order to deliver direct green power with associated environmental value.

The Toyota Tsusho Group plans to scale wind-linked data center capacity in northern Hokkaido to 10–20 MW after 2030 and ultimately beyond 100 MW through integrated wind and data center development.

Tokyo Gas and partners promote on-site gas power as a workaround for grid delays

Tokyo Gas Engineering Solutions (TGES), a subsidiary of Tokyo Gas, announced that it will support data center development by proposing on-site gas-fired cogeneration systems, enabling data centers to start operations even in areas without sufficient grid infrastructure. Working with CBRE and infrastructure consultancy La Clé de Joie, TGES will promote gas cogeneration that can supply both power and cooling, shortening project lead times from up to a decade to around two to three years while also improving resilience during large-scale outages.
