A Bloomberg News analysis of BloombergNEF project tracking has put a number on something the industry has preferred to leave unquantified. Across 22 states, developers have 99 dedicated natural gas plants planned to power AI data centers. More than a third of them are in Texas. Backers include Amazon, Microsoft, OpenAI, Anthropic, and a growing roster of specialized data center operators.
The arithmetic is stark. Those 99 plants, running at standard industry utilization, would emit about 318 million metric tons of CO2 annually. The entire U.S. electric power industry emitted roughly 1,485 million metric tons last year. One slice of data center infrastructure therefore carries the potential to raise national power sector emissions by 20 percent, and by as much as a third if the plants run flat out.
Why Behind-the-Meter Gas Won
The turn to bespoke gas is a direct consequence of the constraints Parselion has tracked all year. Interconnection queues run five times historical norms. FERC's large-load reform process is still unresolved, with all six RTOs having just requested extensions. Grid-supplied power in constrained regions now arrives with multi-year delay and mounting political friction over cost allocation. Against that backdrop, building your own generation is the fastest path to megawatts.
Speed, however, is being purchased with carbon. Every major backer on the list maintains public net-zero or carbon-negative commitments. Dedicated gas capacity at this scale is difficult to reconcile with those pledges through renewable energy certificates or offsets alone, and the disclosure of a concrete plant-by-plant inventory makes the tension considerably harder to manage in sustainability reporting.
A New Regulatory Attack Surface
The immediate risk is not climate accounting but permitting. Gas plants require air permits, and air permits are contestable in a way that data center site plans often are not. Chicago's new executive order explicitly directs increased scrutiny of air pollution permitting for data centers. Local opponents who previously argued about water use and electricity rates now have an emissions argument with federal-scale numbers behind it.
Parselion's assessment: air permitting becomes a top-three schedule risk for behind-the-meter projects over the next four quarters, alongside equipment lead times and water rights. Developers pairing on-site gas with credible carbon capture commitments, grid-flexibility agreements, or firm clean supply will find permitting materially smoother than those treating gas as a purely commercial decision.
