Texas Governor Greg Abbott recently ordered an audit of data center projects seeking connections to the state power grid and instructed the Texas Commission on Environmental Quality to temporarily pause issuing grid-connection permits. However, an open letter from the NAACP Texas State Conference and the NAACP Center for Environmental and Climate Justice highlights that the crackdown leaves major loopholes by failing to address facility developments generating off-grid power.
Minor-Source Permitting Streamlines On-Site Power
An investigation by Floodlight and The Texas Tribune revealed that at least 38 Texas data centers have obtained minor-source environmental permits for on-site power generation since 2024, accounting for more than 2,100 diesel generators. Minor-source air permits were originally established to simplify approval processes for small businesses with limited emissions, such as dry cleaners, gas stations, concrete batch plants, and auto body shops, bypassing extensive public notice and environmental studies.
Data center developments are utilizing these permits at an industrial scale. OpenAI’s Stargate campus in Abilene secured minor authorizations for 10 gas-powered turbines and 62 backup diesel generators, while seeking approvals for 41 additional turbines and 18 generators. According to the investigation, more than half of the identified data centers submitted projected annual nitrogen oxide emissions just below thresholds that mandate public comment and stricter oversight. For instance, a CyrusOne site in Whitney projected 249.1 tons of annual nitrogen oxide emissions against a 250-ton threshold, while a Vantage facility near San Antonio registered 99.8 tons in an area with a 100-ton limit.
Regulatory Focus Leaves Off-Grid Impact Unaddressed
Critics argue that focusing regulatory scrutiny solely on grid connections allows developers to build large-scale private power facilities without evaluating cumulative local effects, including air pollution, water consumption, and noise. The NAACP has filed a notice of intent to sue Vantage Data Centers and VoltaGrid over these permitting practices.
While state officials instructed regulators to align permitting decisions with broader data-center directives, existing frameworks struggle to manage rapidly scaling AI infrastructure relying on off-grid fossil fuel generation.
