## Summary

Dell, Japan's energy firm Jera, and UK‑based Rhaelm announced a joint venture to construct a $15 billion, 400‑megawatt off‑grid AI data centre and accompanying gas power plant outside Tokyo. The project, slated to start operations around 2028, will be one of Asia's largest AI‑focused facilities outside China and is designed to run independently of the national grid.

The partners say the site will provide dedicated, reliable power for high‑performance AI workloads, reducing latency for regional customers and supporting Japan's broader push to expand its AI ecosystem. Dell is expected to supply the computing hardware, Jera will manage the gas‑fired power generation, and Rhaelm will oversee project development and financing. The initiative reflects growing demand for purpose‑built AI infrastructure that can meet the energy intensity of next‑generation models.

If completed on schedule, the centre could host tens of thousands of GPU servers, positioning Japan as a key hub for AI research and commercial services in the Pacific region.

## Key points

- $15 billion investment for a 400 MW off‑grid AI data centre and gas plant near Tokyo.
- Dell, Jera and UK‑based Rhaelm are the three partners behind the project.
- Operations are planned to begin around 2028, making it one of Asia's largest AI sites outside China.

## Why it matters

The facility will add massive, reliable compute capacity in Japan, helping meet rising AI workload demand and strengthening the region's AI infrastructure.
