Skipping the grid queue
The plan’s selling point is speed. The data centre will take power straight from JERA’s plant, rather than wait years for a grid connection.
“We can deliver a 400MW facility years ahead of a conventional grid-connected timeline,” said Bradd Lewis, RHAELM’s chief executive.
Each firm has a set role. JERA brings the land and power, Dell supplies ready-built racks of servers, and RHAELM runs the build.
JERA says it generates about a third of Japan’s electricity.
“JERA is uniquely positioned to power Japan’s AI ambitions,” said Yukio Kani, its global chief executive.
The partners want to copy the model at other JERA sites. The aim is several gigawatts of AI capacity across Japan in the 2030s.
A crowded field
JERA has not put its own figure on that wider rollout. The $140bn estimate comes from the FT’s reporting.
Others are piling in too. In June, Blackstone said it planned $30bn for Japan AI data centres over the next few years.
Japan’s digital minister has warned the country could become an “AI colony” if it falls behind.
