The Texas data center market is building fast. What it is also doing, to the power grid, to residential electricity bills, and to finite water supplies, receives a fraction of the coverage given to project announcements. That imbalance is closing. Regulators, county commissioners, and consumer advocates are now publicly raising questions that the industry has preferred to keep technical. This piece addresses those questions directly.
The Texas data center market is no longer a story about Dallas and Austin. Part 1 of this series covered the five geographic clusters now forming across the state, the power strategies driving site selection, and the federal land angle most coverage is missing. You can read that piece here: Texas Data Center Market Is on Pace to Become the World’s Largest by 2030. This piece covers what that buildout is costing … in grid capacity, in residential electricity bills, and in finite water supplies that have no replacement.
The Texas Data Center Market Is Overwhelming the ERCOT Grid
The numbers are difficult to overstate. More than 220 GW of large projects have applied to connect to the ERCOT grid by 2030, with over 70% of those requests coming from data centers. Texas’s record peak summer demand is roughly 85 GW. The connection queue is more than twice that figure. ERCOT’s interconnection requests grew nearly 300% in a single year. That pace led the grid operator’s own vice president of system planning to say the agency “has outgrown the process that was established for reviewing these large loads.”
ERCOT projects demand could reach between 145 and 218 GW by 2031. The wide range reflects how many of those requests are speculative. But even the lower bound of 145 GW represents 70% growth from today’s peak, and meeting it would require thousands of miles of new transmission lines at an estimated cost exceeding $30 billion.
Texas Senate Bill 6, passed in June 2025, was the Texas data center market’s first regulatory reckoning. It gives ERCOT authority to curtail power to data centers during grid stress events, requires facilities above 75 MW to install remote disconnect equipment, mandates on-site backup generation capable of meeting 50% of load, and requires data centers to pay their share of transmission costs. SB 6 is the floor. The PUC is still writing the detailed rules, with a December 2026 deadline.
The grid response is already reshaping project design across the Texas data center market. Google’s Wilbarger County facility deploys air-cooled technology co-located with AES clean power plants, eliminating both grid dependence and water consumption. Fermi America signed a partnership with Hungarian firm MVM EGI for hybrid dry-wet cooling at HyperGrid, and is pursuing nuclear power specifically to operate outside ERCOT’s constraints. The Chevron-Microsoft West Texas deal structures Chevron as the generation owner, creating a private power supply that sidesteps the interconnection queue entirely. These are not coincidences. They are responses to a grid that cannot absorb this buildout on the traditional timeline.
What the Texas Data Center Market Is Doing to Your Electricity Bill
The grid strain story and the consumer cost story are the same story told from different angles.
Texas residential electricity rates average approximately 16 cents per kilowatt-hour as of early 2026, up roughly 5.75% from a year ago. Over the last five years, residential energy pricing in Texas has risen 30%. Industry analysts project another 29% increase by 2030, driven primarily by $32 billion in new transmission and distribution infrastructure approved by the Public Utility Commission that will be recovered through customer bills. That infrastructure is being built largely to serve the Texas data center market.
The cost allocation mechanism is the specific problem. Under current rules, large industrial users reduce their share of transmission and distribution costs by curtailing during the grid’s tightest summer peak hours, typically four hours across June, July, August, and September. That strategy dramatically lowers what data centers and industrial facilities pay for power lines and poles, shifting the remainder to residential and small commercial customers. PUC chair Thomas Gleeson stated the problem plainly at CERAWeek in March 2026: the state cannot allow infrastructure built primarily for data center customers to land on the backs of residential ratepayers.
The asymmetry is not new, but it is accelerating. A Yale Climate Connections analysis found that between 2020 and 2024, residential electricity prices rose 25% nationally while data centers saw only modest increases and large industrial users actually paid less than two years prior. Residential customers in Texas have no ability to negotiate rates or opt out of cost shifts. More than 40% of Texans are low or moderate income, according to the Texas Energy Poverty Research Institute, and rising delivery charges hit that population first and hardest.
SB 6 begins to address this by requiring the Texas data center market to bear more of the grid investment it generates. The PUC is under a legislative deadline to rewrite cost allocation rules before year-end 2026. Whether that rulemaking produces meaningful change or produces technical compliance that leaves the underlying shift intact. It is the most consequential unresolved question in the Texas data center market right now.
The Water Story the Texas Data Center Market Isn’t Telling
Electricity demand dominates coverage of the Texas data center market. Water consumption is the undercovered constraint with the longer tail risk.
A white paper from the Houston Advanced Research Center released in January 2026 estimates that existing Texas data centers already consume approximately 25 billion gallons of water annually. By 2030, that figure could rise to between 29 and 161 billion gallons per year, potentially 2.7% of the state’s total water use. The HARC benchmark most frequently cited, 300,000 gallons per day, applies to a midsized facility. Hyperscale campuses running at 1 GW or more consume at significantly higher rates. The aggregate exposure across the Texas data center market pipeline is materially larger than the per-facility figure suggests.
The Public Utility Commission began working with the Texas Water Development Board in February 2026 to survey data centers on total water use, cooling technology type, and indirect consumption through power sourcing. Results are to be compiled into a statewide planning report by year-end 2026. It is the first systematic attempt to quantify what is already happening.
The industry’s response has produced real technology commitments. Meta’s El Paso campus uses a closed-loop system that recycles cooling water throughout most of the year and has committed to restoring 200% of consumed water to local watersheds. Microsoft has deployed zero-water evaporation systems that eliminate fresh water intake entirely and is targeting a 40% reduction in water use intensity by 2030. Fermi America has signed a partnership with MVM EGI for the HyperGrid campus near Amarillo, pairing air-cooling with closed-loop systems and evaluating recycled and reclaimed water sources.
Closed-loop systems are meaningfully better than open evaporative cooling, but they are not zero-consumption. Water is still lost through evaporation, blowdown, and mechanical losses. Industry claims about water efficiency deserve scrutiny at the scale the Texas data center market is now operating.
The most Texas-specific solution gaining traction is produced water reuse. West Texas oil and gas operators already run extensive produced water infrastructure. ExxonMobil now recycles 87% of produced water in Permian operations. A Texas Republican resolution formally called on data centers to prioritize recycled produced water to protect aquifers. No major hyperscale campus has announced a produced water agreement yet, but it is the most logical pairing available to the Texas data center market in water-stressed regions.
The Backlash Is Already Here
Hays County Judge Ruben Becerra formally requested a moratorium on permits for new industrial developments with high water demands following a proposed 200-acre data center near San Marcos. Hood County commissioners voted down a similar moratorium 3-2. Both counties sit over or adjacent to critical aquifer recharge zones and have received unsolicited data center proposals faster than their planning infrastructure can evaluate them.
A state senator warned publicly that county-level moratoriums may not be legally permissible under Texas law, as that authority is reserved for municipalities. That legal reality leaves rural county residents with limited formal recourse, and it concentrates the coming fight at the state legislative level. Both sides are already preparing for the 2027 Texas legislative session.
The backlash is not anti-technology sentiment. It is a resource accounting problem. The Texas data center market generates enormous investment, jobs, and tax base. It also generates concentrated demand on power infrastructure, water systems, and local roads built for agricultural and residential use. Communities that signed up for the economic development did not always model the infrastructure liabilities. That gap between expectation and impact is where the next phase of resistance will form.
Frequently Asked Questions
Is the ERCOT grid capable of handling Texas data center growth?
Not at the pace currently proposed. More than 220 GW of large load interconnection requests are pending, with over 70% from data centers, more than twice ERCOT’s current peak demand of roughly 85 GW. ERCOT projects demand could reach 145 to 218 GW by 2031. Meeting the lower bound requires thousands of miles of new transmission lines at an estimated cost exceeding $30 billion. Texas Senate Bill 6 established the first regulatory requirements for how the Texas data center market connects to and uses the grid.
Will data centers raise electricity bills for Texas residents?
Will data centers raise electricity bills for Texas residents? This is an active regulatory concern. Texas residential rates have risen 30% since 2020 and are projected to increase another 29% by 2030, driven largely by $32 billion in new grid infrastructure being built primarily for large industrial users including the Texas data center market. Current cost allocation rules allow data centers to minimize their transmission cost share, shifting the remainder to residential ratepayers. The PUC is under a legislative deadline to rewrite those rules before year-end 2026.
How much water does a data center use in Texas?
HARC estimates a midsized facility uses roughly 300,000 gallons per day, equivalent to about 1,000 homes. Existing Texas data centers collectively consume approximately 25 billion gallons annually. HARC projects statewide consumption could reach between 29 and 161 billion gallons per year by 2030. Hyperscale campuses at 1 GW or more consume at significantly higher rates than the midsized baseline.
Are data centers doing anything to reduce water use?
Yes, with real but limited results. Meta’s El Paso campus uses a closed-loop recycling system. Microsoft has deployed zero-water evaporation technology targeting a 40% reduction in water intensity by 2030. Fermi America is pursuing hybrid dry-wet cooling with a Hungarian technology partner for HyperGrid. Closed-loop systems still lose water through evaporation and mechanical losses. The most promising Texas-specific solution is produced water reuse from existing Permian Basin oil and gas infrastructure.
What is the Hays County moratorium fight about?
Hays County Judge Ruben Becerra requested a moratorium on high-water-demand industrial permits following a proposed 200-acre data center near San Marcos. A state senator warned that counties may lack the legal authority to impose such moratoriums under Texas law. A similar moratorium in Hood County was voted down 3-2 by commissioners. Both fights are expected to escalate heading into the 2027 Texas legislative session.
What is Texas Senate Bill 6?
SB 6, passed in June 2025, is the first major regulatory constraint on the Texas data center market. It gives ERCOT curtailment authority over data centers during grid stress events, requires facilities above 75 MW to install remote disconnect equipment, mandates 50% on-site backup generation, and requires data centers to pay their share of transmission costs. The PUC is writing detailed implementation rules with a December 2026 deadline.
What is produced water reuse and why does it matter for data centers?
What is produced water reuse and why does it matter for data centers? Produced water is the byproduct of oil and gas extraction. West Texas operators have built extensive infrastructure to recycle it. ExxonMobil now recycles 87% in Permian operations. A Texas Republican resolution formally called on data centers to use recycled produced water rather than drawing from municipal systems or aquifers. For the Texas data center market in West Texas, it is the most viable water supply alternative to municipal and aquifer sources.
