AustinTexas county banned all new datacenter construction.
US municipalities once offered datacenter tax incentives; many now block siting outright as AI infrastructure strains power grids and water.
Utah, Virginia and Texas face parallel fights; no federal siting framework governs datacenter power or water use.

THE LOAD PROBLEM
A single hyperscale AI datacenter draws 100-300 megawatts — roughly what a city of 200,000 people consumes. A cluster of them on one grid node can exceed the firm capacity the local utility was built to deliver, forcing either new generation or rationing of existing customers.
THE WATER MECHANIC
Evaporative cooling — the cheapest way to shed heat from server rooms — consumes roughly 1.8 liters of water per kilowatt-hour of compute. A 100MW facility running flat out evaporates millions of liters daily, water that exits the watershed as vapor rather than returning to the aquifer.
THE TAX BARGAIN, REVISITED
Through the 2010s, states competed to attract datacenters with sales-tax exemptions on servers, property-tax abatements, and discounted industrial power rates. The pitch was jobs and ratables; the reality is 30-50 permanent positions per facility and rate-base costs that residential ratepayers absorb when new transmission gets built.
THE PREEMPTION QUESTION
US zoning power sits with counties and municipalities under state enabling acts — the same authority that governs strip malls and feedlots. There is no federal datacenter siting statute analogous to the Natural Gas Act for pipelines or the Atomic Energy Act for reactors. A county ban is legally durable until a state legislature overrides it.
VIRGINIA AS THE PRECEDENT
Loudoun County, Virginia hosts roughly 70% of global internet traffic through datacenter alley — the densest concentration on earth. Dominion Energy now warns it cannot meet demand growth without new gas plants; residents have organized against transmission corridors cutting through historic battlefields. The Texas fight is Loudoun's, two years later.
THE RENEWABLES MISMATCH
Hyperscalers sign power purchase agreements for solar and wind to claim 100% renewable operations, but the grid serves them with whatever's spinning at 3am. The PPAs add green megawatts to the system on average; the actual hourly load is still met by gas, coal, or nuclear. Texas grid operator ERCOT calls this the 24/7 carbon-free gap.
