A major infrastructure initiative is taking shape in Japan as JERA, the nation's leading electricity producer, joins forces with Dell Technologies and RHAELM, a developer based in the United Kingdom, to establish a network of AI data centres. According to reporting by the Financial Times, the entire undertaking could reach $140bn in total investment.
The three organisations formalised their collaboration through a non-binding agreement signed on Thursday, with private equity firm Apollo stepping in as RHAELM's financing partner. The inaugural facility will occupy a 400MW campus positioned adjacent to one of JERA's gas-powered generating stations in Chiba Prefecture, situated to the east of Tokyo. This first phase alone is expected to exceed $15bn, or ¥2.3tn, with commercial operations anticipated to commence around 2028. The Financial Times noted that this installation would rank among Asia's most substantial data centre projects outside mainland China.
Bypassing infrastructure delays
A key advantage of this arrangement centres on accelerating deployment timelines. Rather than enduring the lengthy process of securing connections to Japan's existing electrical grid, the data centre will obtain power directly from JERA's adjacent power plant.

The partnership divides responsibilities strategically: JERA contributes land and electrical supply, Dell furnishes pre-assembled server configurations, and RHAELM oversees construction and operations. JERA currently supplies roughly one-third of Japan's total electricity generation.

The consortium intends to replicate this model at additional JERA locations throughout the country, targeting multiple gigawatts of AI infrastructure capacity by the 2030s.
Intensifying competition
While JERA has refrained from disclosing its own projections for the broader expansion, the $140bn figure derives from the Financial Times' investigation. Japan's data centre sector is attracting substantial international capital, as Blackstone announced in June its intention to commit $30bn toward Japanese AI data centre development over the coming years.
Japan's digital minister has cautioned that the nation risks becoming an "AI colony" unless it maintains competitive momentum in artificial intelligence infrastructure development.
