Texas Data Centers Threaten Air Quality With Gas Power
A new report suggests that on-site power generation could drive nitrogen oxide emissions up by 400% in Texas by 2031.

Should Texas prioritize stricter air quality regulations for new data center developments in your area?
A report from the Houston Advanced Research Center warns that Texas could see significant air quality degradation by 2031 due to the rapid growth of data centers. While the state has improved air quality since 2002, the projected surge in on-site natural gas power usage threatens to reverse these gains.
Why it matters
Data centers increasingly rely on on-site generation to bypass multi-year grid connection delays, creating a conflict between industrial expansion and long-term emission reduction goals. This trend forces policymakers to weigh urgent energy infrastructure needs against local air quality targets.
On-site natural gas engines used for data center backup and continuous power emit approximately four times as much nitrogen oxide as electricity drawn from the state grid. This infrastructure strategy aims to circumvent three-to-five-year grid connection wait times.
The players
Houston Advanced Research Center
An independent research institute focusing on energy, air quality, and environmental sustainability in Texas.
Electric Reliability Council of Texas
The independent system operator that manages the flow of electric power to more than 26 million Texas customers.
Greg Abbott
The current Governor of Texas who has initiated audits of data center connections to the state power grid.
The details
Data centers require massive amounts of power for server operations and climate control systems to prevent hardware overheating. To avoid years-long waits for grid capacity, developers are installing on-site natural gas engines. Nitrogen oxides are a class of chemical compounds produced by combustion that react with other pollutants to form smog. These emissions are currently projected to rise as the state hosts at least 288 planned data center projects.

2031: Projected timeframe for potential emission level increases.
The Tech Race
The rapid deployment of on-site energy generation threatens to undo two decades of progress toward state air quality benchmarks. This conflict pits the urgent demand for 439 gigawatts of power against the state's long-term environmental targets.
Residents in metro areas like Dallas-Fort Worth, San Antonio, and Austin may face worsening air quality if on-site natural gas power becomes the industry standard for new data centers. State audits currently pending under Governor Greg Abbott will determine if new connections proceed under current regulatory frameworks.
The takeaway
The surge in planned data centers, totaling 288 projects, indicates a fundamental shift toward localized power production. Readers should track the results of state-mandated power grid audits, as these will dictate whether developers continue to favor on-site combustion over grid-integrated energy.
