JERA, Dell and RHAELM plan $15B AI infrastructure project in Japan

JERA, Dell Technologies and RHAELM have signed an agreement to come up with a standard model for AI infrastructure in Japan beginning with a $15 billion project near JERA’s Chiba power station.

The partners want to solve power, cooling, and computing problems together rather than separately through a replicable design that will facilitate the faster deployment of AI capacity.

According to JERA’s announcement, RHAELM is in charge of development and delivery; Dell deals with computing infrastructure; and JERA handles power supply and the provision of land.

A template meant to be copied, not a one-off build

The objective is to create more than just one enormous data center. At the moment, AI projects in Japan usually have to establish the power, electrical systems, cooling, and computing infrastructure of their respective sites every time from scratch.

JERA, Dell, and RHAELM aim to create a standard design that can be reused for future projects to make them faster and easier to put together.

The initial test case will be Chiba. If successful, there are plans to expand to more JERA facilities and eventually internationally, as well as building multi-gigawatt AI capacities in Japan in the 2030s.

This development signals an increasing emphasis on power availability in the AI infrastructure race. According to PwC’s forecasts, access to power sources is likely to influence the decisions on where to set up new data centers.

The Chiba project: 400 MW, behind the meter

The initial project will be located next door to JERA’s Chiba Thermal Power Station and have access to as much as 400 MW of power. According to Reuters, the total investment will exceed $15 billion, or approximately ¥2.3 trillion, covering land, power infrastructure, construction, and AI computing equipment.

The facility is meant to obtain all its power requirements through JERA’s generation infrastructure, cutting down the need for a new power grid link. Phased operations, according to Reuters, are scheduled to kick off from 2028 and achieve full capacity by 2029.

JERA is in charge of providing the land and electricity, Dell is responsible for providing standardized rack-scale AI infrastructure, and RHAELM is in charge of development, financing and operations.

Apollo Global Management is expected to join as RHAELM’s strategic investment and financing partner.

Against a multi-trillion-dollar buildout

Chiba’s $15 billion price tag is still small beside the wider spending wave. PwC estimates global data-center capex could reach $31.6 trillion through 2050, with an upside near $50 trillion.

In the nearer term, McKinsey estimates data-center investment could approach $7 trillion by 2030, while the IEA projects electricity use by data centers will roughly double to about 945 TWh by the end of the decade.

The spending is already affecting the broader economy. Cryptopolitan previously reported that AI data-center demand is supporting U.S. manufacturing and nonresidential construction while increasing competition for power, materials and capital.

For Chiba, the real test is whether connecting power and compute through a repeatable design can make that investment cycle faster, cheaper and easier to scale.
