JFE Holdings, Inc. and Mitsubishi Corporation have signed a second Memorandum of Understanding to advance a joint power business and data center project in the Ohgishima, Keihin District. The agreement follows an initial MOU signed in March 2025 to explore the feasibility of such a venture.
The companies, in collaboration with MC Digital Realty, Inc., have conducted technical and commercial assessments over the past year. They plan to develop a data center on five hectares of land, utilizing JFE's captive power plant, which has a generating capacity of 190 MW. The joint venture aims to commercialize the data center as part of JFE's Eighth Medium-Term Business Plan and “OHGISHIMA 2050” land use concept.
Mitsubishi Corporation views data centers and power as essential AI infrastructure and sees this project as a way to repurpose former industrial land. The companies have identified an initial site for development and plan to commence operations for a 60 MW data center by fiscal year 2031, with further expansion in line with demand trends.
JFE and Mitsubishi aim to maximize the use of JFE's power plant to deliver stable and cost-competitive electricity to the data center. They are exploring the reinforcement of the plant's capacity and the potential supply of green power through Ohgishima's planned hydrogen hub.
As demand for data centers grows, JFE and Mitsubishi intend to address the challenges of limited suitable urban sites and the need for a stable power supply. This initiative aims to enhance Japan's industrial competitiveness by contributing to decarbonized societies and sustainable lifestyles.
