SoftBank Group Corp is working to build a massive AI data centre on federally owned land in Ohio that it’s planning to power with roughly $33bn worth of natural gas-fired electricity to be installed by the end of the decade.
SoftBank is looking to build the AI computing complex, capable of drawing 10 gigawatts of power, at a former uranium enrichment complex owned by the US Energy Department, according to a statement issued on Friday. For comparison, a single gigawatt of capacity can power roughly 750,000 homes at any given moment. The company expects the data centre, including the chips and equipment within it, to cost $30bn to $40bn.
While the Trump administration has spoken generally about SoftBank’s $33bn gas project as part of a broader $550bn US-Japan trade deal, this is the first time plans for the AI data centre have been detailed. The company has sourced turbines for the gas project, the first of which is expected to be delivered within a year and the rest coming online by the end of the decade, Rich Hossfeld, co-chief executive officer of SoftBank-backed SB Energy, said. The turbines, capable of generating 9.2 gigawatts in total, will be installed across the region as opposed to at a single complex.
SB Energy said it’s planning another 800 megawatts of new capacity for the data centre, while declining to provide further detail.
The soaring demand for artificial-intelligence tools has touched off a worldwide expansion of data centers, with AI systems requiring enormous amounts of computing capacity. A backlash over the buildout is growing across the US centered on the increasing costs of water and electricity, both of which data centers require in large volumes.
The Trump administration has been trying to address those concerns ahead of this November’s midterm elections by, among other things, exacting pledges from technology companies that they’ll pick up the costs and securing more power commitments. Failure to add more power supplies would also threaten to thwart a key priority for President Donald Trump — winning the AI race against China.
Customers for the Ohio data center have yet to be announced, but the company said they’re coming and that they’ll be involved in sourcing the chips and equipment housed within the facility. At 10 gigawatts, the center would be by far among the largest — if not the largest — in the world. The natural gas project would similarly become the biggest in the US if built, supplying the equivalent of nine nuclear reactors.
SB Energy is working with American Electric Power Co’s local utility to invest $4.2bn in upgrading and building the transmission necessary to support the new load. Hossfeld said equipment for that, including transformers, has already been lined up, stressing that consumers won’t foot the bill. A 10-gigawatt project would be a tremendous undertaking given Ohio only had about 30 gigawatts of total generation as of 2024. As an example, a 3.75-gigawatt natural gas-fired power complex in Florida — currently among the largest in the US — took years to construct and bring online in phases. When Trump first touted the project’s size, industry experts were immediately sceptical. It was later revealed that the biggest US grid operator, whose territory includes the Ohio area, hadn’t been notified of such a project, and Ohio regulators hadn’t been flagged.
"By bringing new power online and upgrading our existing infrastructure, this investment supports the AI boom and cutting-edge technologies while strengthening our energy system and helping keep costs down for the American people,” Energy Secretary Chris Wright said in a statement on Friday.
Wright, White House National Energy Dominance Council chairman Doug Burgum and Commerce Secretary Howard Lutnick — were scheduled to speak in Ohio alongside and SoftBank Chief Executive Officer Masayoshi Son on Friday about the plans for the former uranium enrichment plant.
The unusual gathering of three cabinet secretaries outside of Washington for a press conference underscores the administration’s efforts to show it’s trying to address the backlash to an AI infrastructure buildout that has served as key part of Trump’s agenda.
