OpenAI is moving along in talks to lease a proposed 10-gigawatt data center campus on federal land in Ohio, according to a new report from The Information, in a deal that could include financial backing from Nvidia. This comes as Ohio lawmakers unveiled new legislation aiming to regulate data center build-outs.
The massive 10 GW data center would be the largest data center development ever considered, with a potential buildout cost topping $500 billion based on current prices for chips, labor, and construction materials.
Under the proposed deal, OpenAI would control the chip stacks through a long-term lease and begin making payments once the facility starts operations.
The first phase is expected to come online in 2028. For some context, 10 GW of power is roughly the output of several large nuclear reactors or about 10 large gas-fired power plants running at full capacity. Each GW can power about 700,000 to 1 million homes.
The data center development would require dedicated power generation, substations, transmission lines, cooling infrastructure, access to water or advanced cooling systems, and phased construction over several years.
Simultaneously, Ohio lawmakers have unveiled Substitute House Bill 646, which aims to regulate data center buildouts in the state.
“The Joint Data Center Study Committee has done its job,” Senate Finance Chair Brian Chavez (R-Marietta), who is also the co-chair of the data center committee, said, and quoted by local outlet ABC News 5.
Bill 646 would create a new electric rate class for data centers to ensure that the costs of generation, transmission, and distribution are entirely paid by hyperscalers.
“Make sure the ratepayers are kept harmless, held harmless, and that data centers pay for whatever they’re causing,” Chavez said.
This year alone, Goldman calculates that hyperscalers will unleash $800 billion in data center capex.
