JERA, Dell and RHAELM to Build 400 MW AI Data Centre in Chiba

Japan's biggest power generator JERA has signed an MoU with Dell Technologies and UK-based RHAELM to develop a standardised framework for AI infrastructure, starting with a US$15 billion hyperscale data centre in Chiba.

Japan's largest power generator JERA has signed a memorandum of understanding with Dell Technologies and UK-based AI infrastructure developer RHAELM to accelerate the development of AI infrastructure in Japan, the three companies said on Thursday. The partnership will begin with a US$15 billion hyperscale data centre in Chiba, with Apollo Global Management set to serve as a strategic investment and financial partner for RHAELM.

The companies aim to create a standardised, repeatable and scalable model for building AI infrastructure at a national scale, reducing the lengthy lead times and complexity involved in developing each project independently. The model will be established first in Japan, with opportunities to apply it in other global markets.

In Chiba, JERA will make available land adjacent to its Chiba power station, while RHAELM will develop, construct, operate and finance a 400-megawatt-class hyperscale AI data centre. The companies aim to begin operating the new data centre in phases in 2028 and reach the full 400 MW capacity in 2029, a JERA official said.

JERA will supply 400 MW of power capacity under a 15- to 25-year agreement, while Dell will provide standardised, rack-scale AI infrastructure. The project marks a significant step in Japan's efforts to expand its digital infrastructure and attract investment in AI capabilities.
