Water limits and scarce electric capacity anchor staff's case for pausing new data centers

A work session Oct. 13 lets the City Council review written findings for a temporary halt on data center applications before the ordinance's first reading Oct. 27; adoption would need a three-fourths vote.

City staff have drafted the legal justification for a temporary stop on new data center applications in Denton, and the City Council is scheduled to go over it in a work session on Tuesday, Oct. 13, according to meeting materials posted this week.

The 30-minute discussion is not a vote. It gives council members a chance to shape the findings that would be written into a moratorium ordinance before that ordinance gets its first reading on Oct. 27. Staff offered three choices: keep drafting based on the findings as presented, narrow or change the scope, or halt the process.

The three legal grounds

Texas law allows a city to pause development only when it can document specific needs. The staff report leans on three.

Water and sewer. Denton can produce 48 million gallons of drinking water a day and treat 21 million gallons of wastewater. Average daily demand runs about 18.5 million gallons of water and 15.7 million of wastewater, but peak days have reached 42.2 million and 25.7 million. Staff wrote that data centers without rules on how they are cooled could use more than either system can handle.

Electricity. Denton Municipal Electric has roughly 75 megawatts left for new connections, the report says. ERCOT, under a directive from the governor, is restricting new hookups larger than 75 megawatts, but smaller requests still land with the city, and DME has no process to take in, study and batch them so it does not commit more power than it has. DME has asked ERCOT to approve $300 million in transmission projects to relieve regional overloads; the earliest those could be finished is 2031.

Code detail. Proposed code changes would require closed-loop cooling for future high-performance computing and AI data centers, but staff say the code does not yet spell out what that means technically. A pause would give staff time to write enforceable standards into the Denton Criteria Manuals. This ground cannot be applied to land zoned heavy industrial.

Limits on a pause

Applications filed before a moratorium takes effect could not be stopped, because of the state's vested-rights rules. The pause could reach both the city limits and the extraterritorial jurisdiction. It would need the votes of at least three-fourths of the full council, would last 90 days with one possible 90-day extension, and could not be imposed again on the same area for two years.

The presentation lays out a second public hearing and first reading Oct. 27 and a second reading and final vote Dec. 1. With an extension, the slide shows the moratorium ending May 31.

Two projects already approved

Denton has two large data center projects approved on city-owned land. Core Scientific leases about 78 acres for an AI and high-performance computing center with a power purchase agreement of up to 391 megawatts at peak and a closed-loop cooling system. WAHA/Qumulus AI leases 4 acres for a modular crypto-mining site using up to 20 megawatts and air cooling.

The report says both pay all of their power and transmission costs and buy renewable energy credits covering their full annual use, and that together they have produced more than $3.1 million in property taxes, $475,000 in sales tax and $8.8 million in electric return on investment and franchise fees.

The moratorium effort traces to a two-minute pitch from Mayor Pro Tem Nick Stevens in May. The council held the first required public hearing Sept. 22. Separately, the council's evening session on Oct. 13 includes the public hearing on the data center code amendments the Planning and Zoning Commission recommended in September.
