OpenAI Secures 8 GW at Ohio AI Data Center Campus Backed by 10 GW of New Power
OpenAI has secured about 8 GW of AI capacity at Ohio’s PORTS-Pike campus, pairing massive compute growth with new generation and transmission investment.

The OpenAI Ohio AI data center project has secured approximately 8 gigawatts of AI computing capacity at the PORTS-Pike Technology Campus in Pike County, putting one of the largest planned data center developments in the United States behind an equally extraordinary buildout of new power and grid infrastructure.
The August 17 agreement brings together OpenAI, NVIDIA and developer SB Energy at a campus that is planned around 10 GW of new electricity generation and billions of dollars of new regional transmission infrastructure.
NVIDIA said the initial deployment is expected to provide 4.25 GW of AI factory capacity, with the company retaining the option to extend its arrangement to another 3.75 GW. That would correspond with the approximately 8 GW-IT OpenAI says it has secured at PORTS-Pike.
The scale makes the project particularly important for the energy industry because PORTS-Pike is being developed around a power-first model in which generation, transmission and computing capacity are being planned together rather than treating electricity supply as a connection secured only after the data center is built.
OpenAI Ohio AI data center pairs 8 GW of computing with 10 GW of planned generation
The electricity infrastructure surrounding PORTS-Pike is nearly as remarkable as the computing campus itself.
The U.S. Department of Energy said SB Energy plans to build 10 GW of new power generation associated with the broader PORTS development.
The difference between the approximately 8 GW-IT committed to OpenAI and the larger generation buildout is important. An IT-gigawatt describes power available primarily to computing equipment, while an operating data center also requires electricity for cooling, power conversion and other facility systems. Generation capacity also must account for reliability and operating requirements rather than simply matching IT load one-for-one.
OpenAI said it intends to pay its project-specific energy and infrastructure costs and that its participation is structured around avoiding the transfer of those project expenses to surrounding households.
This approach is becoming increasingly important as utilities confront requests from individual data center developments that can rival the electricity consumption of cities and major industrial regions.
Natural gas accounts for most of the announced generation plan
The PORTS-Pike power strategy should not be characterized primarily as a renewable-energy development.
According to the Department of Energy, the 10 GW generation plan includes approximately 9.2 GW of new natural-gas generation associated with the U.S.-Japan Strategic Trade and Investment Agreement.
The publicly available project materials reviewed by Microgrid Media do not establish that the remaining generation capacity will come from any single specified technology.
That distinction matters when evaluating the project from a microgrid, distributed-energy or emissions perspective. PORTS-Pike demonstrates the growing importance of dedicated generation for AI infrastructure, but dedicated power does not necessarily mean clean power or a conventional microgrid.
It also illustrates the increasingly direct relationship between data center development and new power-plant construction. Instead of waiting for sufficient capacity to become available on the existing grid, some developers are attempting to develop generation and computing infrastructure in parallel.
$4.2 billion of transmission infrastructure is planned
Generation is only part of PORTS-Pike’s energy strategy.
AEP Ohio says approximately $4.2 billion of new electric transmission infrastructure is planned to support data center development in southern Ohio.
The utility said the investment will include new 765-kV transmission infrastructure, with SB Energy committed to paying for the transmission investments associated with serving the site.
AEP Ohio subsequently detailed plans that include a new substation in Pike County and roughly 50 miles of 765-kV transmission between the planned Baku Substation and the existing Gavin Substation.
That means the campus should not be viewed simply as an isolated power plant serving an isolated computing facility. The proposed generation and data center infrastructure will interact with a significantly expanded regional transmission system.
The arrangement provides one example of an issue now confronting regulators around the country: how utilities can accommodate exceptionally large new data center loads without requiring existing customers to subsidize substations, transmission and other infrastructure built primarily to serve them.
PORTS-Pike is different from a conventional data center microgrid
The enormous amount of dedicated generation may make PORTS-Pike resemble a microgrid at first glance, but the available project information does not establish that the entire campus will operate as an islandable microgrid capable of disconnecting from the surrounding power system.
That distinguishes it from projects such as the 350 MW AI data center microgrid in New Albany, which combines on-site generation and battery storage around an explicitly identified microgrid architecture.
The OpenAI Ohio AI data center instead represents a broader power-first model: secure land, generation, transmission and electrical infrastructure alongside the computing capacity.
For the energy industry, the distinction is significant. Microgrids are one possible response to grid-constrained data center growth, but dedicated utility-scale generation, privately funded transmission, battery storage, fuel cells and specialized utility service arrangements are emerging alongside them.
The project is still moving through federal permitting
Despite the scale of the commercial commitments, PORTS-Pike should not be treated as completed infrastructure.
The federal Permitting Council added the PORTS Technology Campus to the FAST-41 permitting program in June, placing the development under coordinated federal environmental review and permitting.
The federal permitting dashboard continues to list the project’s environmental review and permitting status as in progress.
Individual generation, transmission and data center phases will therefore still need to advance through permitting, construction and commissioning before the full planned capacity becomes operational.
Capacity is expected to arrive in phases
NVIDIA says its support for the PORTS-Pike infrastructure will become effective in phases as data centers are placed into service between 2028 and 2030.
AEP Ohio, meanwhile, has said it expects power to begin flowing to the site through its planned transmission infrastructure in 2029.
Those timelines are not necessarily contradictory because a multi-gigawatt campus can enter service in stages using different pieces of generation and electrical infrastructure as construction progresses.
OpenAI expects the broader development effort through 2032 to support approximately 35,000 construction jobs and about 2,500 long-term operating jobs.
The company also announced another $40 million contribution to a community grant fund, following an earlier $40 million commitment from SB Energy.
Why PORTS-Pike matters for the data center power market
The OpenAI agreement strengthens a trend that is rapidly changing data center development: access to computing capacity is increasingly inseparable from access to electricity infrastructure.
At approximately 8 GW-IT, the project pushes that challenge into territory normally associated with major utility systems rather than individual commercial customers.
Planning roughly 10 GW of generation and billions of dollars of transmission infrastructure around a single AI campus demonstrates just how large the electricity requirements of next-generation computing facilities can become.
The next major milestones will include progress through federal permitting, construction of the initial data center phases, development of the proposed generation fleet and completion of the transmission infrastructure needed to connect the campus to the surrounding grid.
If completed at the announced scale, the OpenAI Ohio AI data center could become an important test of whether power-first development can provide a repeatable model for bringing massive AI loads onto constrained electricity systems.
