The Ohio Project: A Bridge Between Traditional and Digital Energy
In March 2026, the U.S. Department of Energy and Commerce announced a public-private agreement with SoftBank and AEP Ohio for a $33.3 billion investment. The project involves the construction of a 9.2 gigawatt natural gas power plant and a 10 gigawatt data center campus in southern Ohio, on a redeveloped former Portsmouth Gaseous Diffusion Plant site. This plan, announced in a press release on March 20, aims to provide dispatchable and continuous power for the expansion of AI, a sector that requires an unprecedented amount of power.
The choice of natural gas, despite growing pressure for renewable sources, reveals a pragmatic strategy. While the conflict in the Gulf and the closure of the Strait of Hormuz destabilize global energy markets, the United States is focusing on a domestic and easily manageable resource. The power plant, designed to be operational by 2030, will be powered by North American reserves, reducing dependence on imports vulnerable to geopolitical disruptions. This approach highlights a paradigm: technological innovation cannot be separated from a robust and autonomous energy infrastructure.
Technical Architecture: From Source to Processor
The Piketon natural gas power plant will be equipped with combined cycle turbines, capable of converting 60% of the heat into electricity, a higher efficiency than the global average. Its design includes a 2 million cubic meter liquefied natural gas (LNG) storage system, located near an existing distribution network. This allows for a rapid response to peak demand, typical of data centers. The data center campus, instead, will be built on an area of 100 hectares, with a modular design that allows for expansion to 20 GW by 2035. Each module will be equipped with water cooling, powered by an integrated desalination system, to reduce environmental impact.
The project utilizes state-of-the-art technologies, such as low-loss capacitors and real-time monitoring systems. The collaboration with AEP Ohio ensures a direct connection to the regional electricity grid, while SoftBank is responsible for operational management. This model, which combines production, distribution, and consumption, represents a rare example of vertical integration in the energy sector. The choice of a redeveloped industrial site reduces acquisition costs and utilizes existing infrastructure, such as extraction wells and transmission lines.
Economic and Geopolitical Impacts
The project will generate approximately 15,000 jobs during construction and 3,000 permanent jobs once operational. The companies involved, including SoftBank and AEP Ohio, will see an increase in their market share. However, the cost of natural gas, which has reached $9 per MMBtu due to tensions in the Gulf, could reduce profit margins. To mitigate this risk, the federal government has guaranteed a fixed price for natural gas for the first ten years, an incentive that attracts investors but could increase public debt.
The dependence on natural gas highlights a contradiction: while the AI sector seeks to reduce its carbon footprint, the energy required to power its operations requires low-cost and highly available sources. This creates a tension between climate goals and economic needs. Furthermore, the strategic location of the Strait of Hormuz, through which 20% of the world’s oil passes, makes the project vulnerable to external disruptions. If the Strait remains closed for months, the price of natural gas could rise further, jeopardizing the sustainability of the project.
Prospects and Indicators to Monitor
My impression is that the Ohio project represents a long-term bet on the balance between technological growth and energy security. Two key indicators will be the progress in the construction of the power plant and the price of natural gas. The first phase, scheduled for 2030, must demonstrate that the integration between production and consumption can work without interruptions. The price of natural gas, instead, will be a barometer of geopolitical tensions: if it rises to $12 per MMBtu, the project could become unprofitable. Furthermore, the evolution of energy storage technologies, such as the thermal batteries mentioned in STREAM_A, could reduce dependence on natural gas, offering a more sustainable solution in the long term.
