Ishikari Renewable Energy Data Center No. 1 LLC
Ishikari Renewable Energy Data Center No. 1 LLC is pleased to announce the completion of Ishikari Renewable Energy Data Center No. 1 (hereinafter referred to as "the facility") on March 27, 2026. The facility will commence full-scale operations as a green data center powered entirely by renewable energy from Ishikari. We will proceed with fit-out work, with partial operation of data halls scheduled for August 2026. In conjunction with the commencement of operations, the facility will be connected to Tokyo (Otemachi) via NTT East Corporation's IOWN All-Photonics Network (APN), overcoming previous challenges of communication distance and latency to enable high-speed, high-capacity, low-latency, and energy-efficient communication. By August 2026, the facility will be capable of receiving over 10MW of power, and after a certain period, the system for supplying the entire 15MW of electricity will be established. To meet the recent surge in AI demand, one of the six data halls has been designated as a water-cooling and liquid-cooling compatible dedicated room, capable of housing AI servers such as B200 and B300. An open house will be held in June 2026.
