Home-Rule Authority Faces Its First Real Test in San Marcos

San Marcos has banned new data centers outright, and Senator Bettencourt wants the courts to decide whether home-rule cities can do that. The answer reshapes site selection across every Texas municipality, and developers who read the regulatory grain now will pick their jurisdictions before the precedent lands.

Today's Lead

Texas is now the test case for whether local governments can stop data centers at all. San Marcos became the first Texas city to ban them outright, passing a 4-3 zoning ordinance on June 16, and state Sen. Paul Bettencourt is already signaling a direct challenge under House Bill 2559 and the 2023 Death Star Law. Counties are losing the same fight: Hill County rescinded its moratorium after a developer sued for $100 million, and Hood County backed off after Bettencourt asked the Attorney General whether counties can restrict data centers at all.

The stakes are statewide. As Lockhart council member Taylor Burdge put it, "All cities are watching what happens to San Marcos." If the ban survives, expect a wave of municipal ordinances and a fragmented permitting map. If it falls, home-rule strategy collapses.

Texas signals regulation while New York freezes

Abbott shifted from calling Texas an "AI epicenter" to flagging data center regulation as a 2027 legislative priority, and he's proposed eliminating the state sales tax exemption. That's tightening, not closing. New York's legislature, by contrast, sent Gov. Hochul a 12-month moratorium that layers an 18-month environmental study plus prevailing-wage and on-site mitigation costs, pushing the effective freeze well past a year. Ohio paused new sales-tax exemptions on May 27 with 210 facilities already operating.

The U.S. controls 74% of global high-end compute, per Federal Reserve analysis. Texas keeps its queue open and its rules negotiable; the states that freeze hand site selection to whoever stays open. The risk for developers is misreading Texas tightening as Texas closing, and skipping the rulemaking where the conditions get written.

Power

Commitment-first planning rewrites the queue, and hyperscalers build around it

FERC, ERCOT, PJM, and Southwest Power Pool are converging on commitment-first planning to strip speculative megawatts out of forecasts. Google's FERC filing proposes long-term service agreements, upfront collateral, and withdrawal penalties to sort serious projects from option-shopping; Amazon, Microsoft, and OpenAI back variations. Meanwhile the four largest buyers stopped waiting. Microsoft secured Chevron gas for a 2.67 GW West Texas site without touching ERCOT's queue; Google signed a 1 GW TotalEnergies solar PPA for Texas. By 2025 the four controlled 49% of global clean PPAs.

The grid isn't slow. It's full, and the biggest tenants are financing their own way around it. The risk: speculative multi-utility filings now carry real cost. Developers who lock generation and anchor demand before queuing move first; the rest wait behind them.

Water

Texas can't see what's coming, and that's the policy problem

Texas hosts at least 248 planned projects, per Texas Tribune analysis, but the state doesn't track them. Location, capacity, and resource data reported to grid operators stays confidential. Rachel Hanes of the Greater Edwards Aquifer Alliance notes the industry "has long relied on non-disclosure agreements and on not having any rules or requirements for their disclosure and reporting." Water demand concentrates exactly where stress already lands: the Edwards Aquifer in the Hill Country, the Ogallala in West Texas, North Texas surface supplies. Last year's floods forced Texas sites onto backup diesel.

Abbott has asked ERCOT to impose operational limits on data centers, citing affordability. Expect disclosure requirements and water-offset verification to become standard conditions. Developers who put water first in site selection won't be surprised when those rules arrive; the ones who pencil in water after the fact will find the assumption didn't hold.
