Two concurrent signals arrived in San Antonio's regulatory record within the past year. In October 2025, District 6 Councilmember Ric Galvan filed a Council Consideration Request calling for a formal city policy discussion on data center growth and its impacts on the electric grid, water supply, and neighborhoods. Then, in late May 2026, the Texas Commission on Environmental Quality held a public hearing on Vantage Data Centers' proposed TX-2 facility on Rogers Road — a $157 million, 360,000 square foot project on San Antonio's West Side, according to News4SanAntonio. Together, these signals mark a transition: infrastructure allocation pressure in San Antonio is no longer a speculative risk. It is in the regulatory record — and the rules being written now will govern how CPS Energy and SAWS handle competing demands from data centers and industrial users alike. If your capital plan assumes stable power availability or expandable water access, the policy discussion at City Hall is already relevant to your next budget cycle.
San Antonio's Data Center Buildout, by the Numbers
According to a dataset from Galvan's office, as reported by KSAT in November 2025, approximately 50 data centers are either completed or planned in the San Antonio region. Nearly 15 are concentrated in District 6 alone — the far West Side and northwest corridor — where Microsoft also operates a multi-building campus at Texas Research Park, west of SH-211. KENS5 reported in October 2025 that the Austin-to-San Antonio corridor ranks among the largest data center markets in Texas.
No source has confirmed the specific power draw or water consumption volumes for these facilities in aggregate. CPS Energy and SAWS have not released public statements quantifying data center demand. What the record does confirm: the scale of geographic concentration, formal city acknowledgment of grid and water concern, and an active TCEQ permitting process now underway.
The Infrastructure Dependency This Exposes for Manufacturers
Data centers are large, continuous loads. A single hyperscale facility can draw tens of megawatts around the clock and requires significant cooling water. When multiple facilities cluster in the same utility service corridor, they do not displace existing customers overnight — but they do reshape the queue for capacity additions, influence how utilities plan grid investments, and create policy conditions that affect how future load growth requests are handled.
San Antonio manufacturers on the West Side and northwest corridors share CPS Energy grid infrastructure with this data center concentration. No policy yet governs how CPS Energy or SAWS prioritizes capacity between data center tenants and industrial users. The Galvan CCR is the first formal step toward writing that policy.
The near-term risk is not an outage. The risk is that capital plans built on assumptions about power availability, expansion capacity, or utility costs are approved before those assumptions are verified against the infrastructure environment that will exist when the projects execute.
Which Manufacturers Should Pay Attention
The most directly exposed operators are those that:
- Run facilities on San Antonio's West Side, far West Side, or northwest corridor
- Operate energy-intensive equipment: compressed air systems, electric arc furnaces, large HVAC loads, industrial chillers, or continuous process lines
- Depend on process water from SAWS for cooling, rinsing, or direct production use
- Have facility expansion or equipment upgrades in a 2–5 year capital pipeline that assume current utility cost or capacity levels
If your plant is not in those corridors, the geographic risk is lower — but the policy risk is not. Any framework written in response to the Galvan CCR will apply to how CPS Energy and SAWS handle industrial load growth across the city.
What Your Utility Agreements Actually Say
Most mid-market manufacturers have not reviewed their CPS Energy service agreements since the facility was built or last expanded. Those agreements contain rate classification, demand charges, load curtailment provisions, and interconnection queue terms for expansion requests. If they have not been reviewed recently, you do not know what protections or obligations are already in place.
The same applies to SAWS industrial water accounts. Water service agreements for industrial users can include demand-management clauses and allocation caps. If your expansion plan assumes water availability at current volumes, verify that against your current account terms.
Neither CPS Energy nor SAWS has publicly stated any intent to restrict or reallocate industrial capacity due to data center demand. The issue is that the policy framework governing how those decisions would be made does not yet exist — and it is being drafted now.
Planning Assumptions to Revisit
Before the next capital planning cycle, examine:
- Rate classification: Is your facility classified as industrial, commercial, or large-load under CPS Energy's tariff schedule? Rate class affects how you are treated in capacity planning and future demand requests.
- Service agreement terms: Does your agreement include provisions for load growth, demand peaks, or curtailment? Are there capacity limits that would require a new interconnection request for a planned equipment upgrade?
- SAWS water service terms: Does your industrial water agreement include allocation caps or demand-management triggers?
- Facility geography: Is your plant within the West Side or northwest San Antonio data center concentration zone? If yes, the policy discussion at City Hall is directly relevant to your infrastructure.
- Capital plan utility assumptions: Identify any 3–5 year projects that assume stable utility cost, available grid capacity, or expandable water access, and flag those for verification before project approval.
What to Audit Now
The audit requires pulling documents your facilities team should already have:
- Your current CPS Energy account and service agreement
- Any pending capacity or load growth requests with CPS Energy
- Your SAWS industrial water service account and agreement
- Your facility address, mapped against the District 6 data center concentration zone
If those documents are current and your team has reviewed them in the past 18 months, you are in reasonable shape. If they have not been reviewed since your last facility change, do it before the city policy discussion produces a framework you had no input into.
What to Watch in the Months Ahead
The TCEQ hearing on the Vantage TX-2 permit has concluded, but the permit outcome has not been reported. Approval, denial, or conditions imposed by TCEQ will signal how state environmental review treats large-load facilities in this corridor going forward.
The Galvan CCR remains in process. As of available reporting, no council vote, ordinance, or formal study has been commissioned following the October 2025 filing. When that changes, it will determine whether San Antonio creates any formal protection or priority framework for industrial users sharing infrastructure with data centers.
Watch for CPS Energy rate filings or capacity planning statements that reference data center load growth. Watch for SAWS industrial water planning announcements. Watch for additional Council Consideration Requests or zoning actions targeting data center siting near existing industrial corridors — those will indicate whether this is a single-district concern or a city-wide policy shift.
The window to be ahead of this policy discussion is open. It will not stay open.
