- Bloomberg New Energy Finance found 100 GW of on-site gas-burning capacity is planned to power US data centers, equivalent to 18% of all existing US natural gas power plant capacity.
- Richland Parish, Louisiana is hosting a 2.2 GW data center, while a facility near Cheyenne, Wyoming starts at 1.8 GW and scales to 10 GW — both relying on on-site gas generation.
- On-site gas plants could spike American energy bills more than grid-connected data centers, because they sign gas supply contracts outside the jurisdiction of state utility regulators.
- Natural gas supplies 43% of US electricity and gas-fired generators set the marginal electricity price in most hours, so data center gas demand raises bills for non-data-center customers as well.
- xAI is being sued in Southaven, Mississippi for Clean Air Act violations from unpermitted, polluting gas turbines; combined-cycle turbines are back-ordered 5–7 years, forcing tech firms onto dirtier equipment.
- Google's Minnesota data center will run on 1.6 GW of wind and solar backed by 300 MW of batteries, and Amazon outbid a local utility for 1.2 GW of solar and 1.2 GW of battery storage to power its Oregon data centers.
- State policy tools the authors recommend include permit-by-rule frameworks and pre-authorized zones like Texas's Competitive Renewable Energy Zones, Nevada's Solar Energy Zones, and Arizona's Renewable Energy Incentive Districts, alongside Michigan's HB 5120 and Illinois's HB 4412.
Why it matters: The article reframes the data center energy debate: on-site gas plants are pitched as protecting the grid, but they bypass utility oversight and could end up charging consumers more than regulated grid connections would. With 100 GW of such capacity planned and public opposition to data centers at an all-time low, the policy fight over whether tech firms must bring their own clean power — not just their own power — is moving to state legislatures.
