Texas halts new data center grid connections as states reassess electricity demand
Texas has frozen new grid connections for data centers to investigate electricity demand, which has been inflated by speculative projects. Other states like Pennsylvania and Ohio are enacting similar rules, such as upfront payments and stricter permitting, to manage the surge in data center power requests. This national reckoning aims to address "ghost demand" threatening grid stability and reliable electricity supply across the US.
The United States is grappling with a significant challenge as data centers demand electricity equivalent to powering every home in the country, with much of this demand potentially being speculative or an "illusion." Texas has taken a leading step by becoming the first major data center hub to freeze new grid connections for these facilities and launch an investigation into their plans.
This move by Texas, spearheaded by the Texas Public Utility Commission and Governor Greg Abbott, involves a comprehensive audit requiring data center proposals to reveal ultimate ownership, detail taxpayer-funded incentives, and disclose water use and on-site power generation. PUCT Chairman Thomas Gleeson emphasized the necessity of accurate information for ensuring grid stability and reliability. Since 2023, data center connection requests to ERCOT have surged from 48 gigawatts to over 474 gigawatts, making Texas a global hotspot for AI and cloud server development.
Other states and utilities are following suit to address this intensifying problem. Pennsylvania Governor Josh Shapiro signed an executive order implementing stricter permitting requirements for projects over 25 megawatts and demanding greater disclosure of project plans. In Ohio, AEP Ohio's data center power demand pipeline significantly dropped after the state adopted rules including grid connection study fees. Similarly, Chicago-based Exelon reduced its high-probability data center demand forecast by 40% after implementing stricter collateral requirements. Consumer advocates, like Tyson Slocum of Public Citizen, warn that this uncertainty risks either under-building critical grid infrastructure or over-building for projects that never materialize, ultimately burdening consumers with higher costs.
Despite efforts to filter out speculative demand, substantiated data center requests continue to stress existing grids, with entities like PJM Interconnection reporting a $29.4 billion increase in capacity costs due to data center demand. This situation underscores a broader national effort to bring transparency and order to an industry that, in many areas, has operated with minimal oversight.
