Texas data centers are not the main driver of higher electric bills, study says

A new survey from TexasElectricityRatings.com says residential power prices have risen far faster nationwide than in Texas, even as data center demand surged. The findings come as Texas tightens rules on large power users and ERCOT audits a massive queue of new load requests.

Why it matters: - Texas is adding hundreds of data centers as AI and cloud computing expand, raising concerns that residential electricity bills could rise. - The study suggests the bigger drivers of higher consumer bills have been aging infrastructure, transmission upgrades, equipment shortages and rising fuel costs. - Texas policymakers are already changing grid rules for large power users, which could shape who pays for future expansion.

What happened: - TexasElectricityRatings.com released a survey comparing 20 years of residential electricity rates, utility costs and data center growth nationwide. - The study found U.S. residential electricity prices rose nearly 83% from 2006 to 2026. - Texas electricity rates rose 37.35% over the same period. - Texas electricity prices fell 8.81% from 2006 to 2016. - The company said data center energy demand increased from 1% to 4.7% of total U.S. demand during the study period. - The survey did not confirm data centers as the main cause of rising bills because many states with heavy data center growth did not see matching rate spikes.

The details: - Virginia added more than 600 data centers and saw rates rise 44.83%. - Texas has roughly 520 data centers and saw rates climb 50.62%. - California had far fewer data centers than Texas or Virginia but recorded a 184.27% rate increase, the steepest in the nation. - Google opened its first two Texas data centers in 2009, helping mark the start of a rapid expansion in cloud infrastructure. - Texas passed Senate Bill 6 in 2025 to create new rules for large power users through the Public Utility Commission and ERCOT. - Under the law, large loads must post substantial deposits. - The law requires existing generation to stay available for homes and small businesses. - The law shifts new infrastructure costs to the large loads that require them. - ERCOT’s Batch Zero Connection Process studies large load projects as a group rather than one at a time. - On Aug. 3, 2026, Gov. Greg Abbott paused Batch Zero to launch an audit of every large load project in the queue. - The audit will verify grid usage, water usage, financial assistance and ownership information. - ERCOT’s interconnection queue now holds 466.5 GW of large load requests. - About 90% of those requests are tied to data centers. - ERCOT expects roughly half of the remaining requests will never go live.

Between the lines: - Texas appears to be trying to get ahead of the costs and congestion that can come with rapid load growth. - The study’s state-by-state comparison suggests data centers may be one factor in higher bills, but not the only one and not always the biggest one. - The audit and new deposit rules point to a tougher environment for speculative projects that want access to the grid.

What's next: - Most analysts expect Texas to have enough electricity supply for both residents and data centers by 2032. - The bigger question is whether Texas can keep power affordable as AI demand grows and new industrial loads arrive. - The full survey is available here.
