Overview
- The Energy and Commerce departments outlined a partnership with SoftBank’s SB Energy and AEP Ohio to develop a 10‑gigawatt data campus at the Portsmouth federal site paired with 10 GW of new generation.
- About 9.2 GW of the new power is slated to be gas-fired with roughly $33 billion in Japanese-backed funding and turbines scheduled for regional deployment through the end of the decade.
- SB Energy plans approximately $4.2 billion in transmission upgrades with AEP Ohio, with reporting that the costs will not be passed to ratepayers.
- Initial delivery targets call for about 800 MW by early 2028, with construction expected to begin in 2026.
- SoftBank has not identified customers for the site, and coverage flags growing scrutiny over scale, emissions, water use, and grid impacts.
