Hokkaido Electric Power Company is facing a significant challenge as the northernmost prefecture of Japan emerges as a hotbed for data center and semiconductor manufacturing. The influx of tech giants seeking to capitalize on Hokkaido’s cold climate and renewable energy potential has raised concerns about the region’s power supply capacity.
The Japan Times reported that Susumu Saito, president of Hokkaido Electric Power, emphasized the critical role of the Tomari No. 3 nuclear reactor in meeting the surging demand. The reactor, which was shut down following the 2011 Fukushima nuclear disaster, remains idle. Its potential restart is seen as a key factor in ensuring a stable power supply for the region.
Hokkaido’s attractive climate and renewable energy resources have made it a prime location for data centers. One of the most significant projects is the joint venture between SoftBank and IDC Frontier, which aims to build Japan’s largest data center in Tomakomai City. This massive facility, with a projected power capacity of over 300 MW, is expected to be operational by fiscal year 2026.
The increased demand for electricity raises questions about the balance between economic growth and environmental sustainability. While nuclear power can provide a reliable energy source, it also carries risks and public concerns.
