Power Workarounds Meet Local Pushback
Yesterday's clearest movement was not a new mega-campus announcement but tighter scrutiny around how data centers get powered and approved. In Mississippi, xAI is operating nearly 50 trailer-mounted gas turbines at a data center under a mobile-equipment classification that has kept the first year outside normal air regulation; an NAACP-backed lawsuit is now asking a court to stop the setup, arguing federal law may still treat the turbines as stationary sources. Only 15 turbines have permits.
Local governments elsewhere slowed the runway rather than stopping projects outright. Pulaski County, Arkansas sent proposed data center rules back for drafting after a heated hearing, instead of immediately imposing new disclosure and monitoring requirements as AVAIO and Google projects advance. In Ohio, Canton heard sharp debate over an Amazon-backed 240 megawatt campus and a proposed 75 percent property-tax abatement for 30 years, with the next vote scheduled for May 18.
Water and construction compliance also kept moving from side issue to live constraint. Arizona's Project Blue was hit with a county dust violation after the city already shut off a contractor's water meter over improper use, while Fayette County, Georgia retroactively charged QTS $147,474 for unauthorized and unmetered water hookups. These are local enforcement actions, not project killers by themselves, but they add cost, delay risk, and political heat once construction is underway.
Key Points
- xAI's Mississippi site is using nearly 50 trailer-mounted gas turbines, and plaintiffs say only 15 are permitted while federal air rules may still apply.
- Pulaski County, Arkansas delayed immediate data center rules and sent disclosure and monitoring proposals to planning staff for drafting within 90 days.
- Canton, Ohio held a contentious hearing on an Amazon-backed 240 megawatt campus and its proposed 30-year, 75 percent property-tax abatement; council vote is set for May 18.
- Arizona's Project Blue received a dust violation after earlier water-meter problems, and Fayette County, Georgia billed QTS $147,474 for unauthorized and unmetered water use.
Implications
On-site generation is becoming a practical answer to grid delays, but it also creates new air-permitting and litigation risk that can erase some of the speed advantage.
Counties and cities are shifting from broad data center enthusiasm to project-specific demands on disclosure, utility impacts, water use, and tax terms.
Once construction starts, basic compliance on water and air can quickly become a schedule and community-relations problem.
Things to watch
Watch
Whether a court or regulators force changes to xAI's turbine setup in Mississippi, especially if the units are treated as stationary sources under federal law.
Watch
The May 18 Canton vote on tax abatements for the Perry Township campus and any conditions added before the project reaches county commissioners.
Watch
The Pocatello hearing on a 59-acre AI data center site, where Idaho Power has indicated at least 100 megawatts of capacity but wastewater details remain under review.
