ChainThink report: SB Energy, a subsidiary of SoftBank, has leased federal land located in Piketon, Ohio, from the U.S. Department of Energy to construct a 10GW data center campus named PORTS TECHNOLOGY CAMPUS. The site was formerly the Portsmouth Gaseous Diffusion Plant, historically used for producing enriched uranium required for nuclear weapons.

SB Energy will simultaneously develop 10GW of new power generation capacity, with at least 9.2GW derived from natural gas, and has entered into a $4.2 billion agreement with American Electric Power Ohio to upgrade electricity transmission infrastructure in southern Ohio, with power delivery expected by 2029. SB Energy has committed to funding accelerated remediation of legacy nuclear contamination at the site.

The project is backed by a Japan-U.S. consortium including Hitachi, Mitsubishi Electric, Toshiba, TDK, Sumitomo Mitsui Banking Corporation, Bechtel, Morgan Stanley, Goldman Sachs, and JPMorgan Chase. Concurrently, nuclear energy developer Oklo and Centrus Energy are jointly constructing an uranium processing facility on the same site, while Meta has also selected the location to plan a nuclear-powered data center campus with a target capacity of up to 1.2GW.
