Texas Freezes Data Center Grid Connections to Combat 'Ghost Demand'

Texas has become the first major U.S. data center hub to freeze new grid connections for these facilities, launching an investigation into a massive surge in electricity requests. The move reflects a growing national effort by regulators and utilities to distinguish legitimate projects from speculative "ghost demand" fueled by the artificial intelligence boom.

The Scale of 'Ghost Demand'

Across the central and southern United States, data centers have requested over 700 gigawatts of electricity, a figure more than 10 times the industry's estimate of current U.S. data center power consumption, according to a Reuters review of utility and grid data. In Texas alone, requests to connect to the state's grid operator, ERCOT, have soared from about 48 gigawatts in 2023 to more than 474 gigawatts, according to documents from ERCOT and Governor Greg Abbott.

Regulators and consumer advocates have warned that many of these requests are likely duplicative or from developers lacking the necessary funding, creating significant uncertainty for long-term grid planning. "When you don’t know what is real, you really don’t know how to build the infrastructure for it," Texas Public Utility Commission Chairman Thomas Gleeson said at a March industry conference.

States and Utilities Impose Guardrails

To address the uncertainty, Governor Abbott's order initiated a comprehensive audit, requiring data center proposals to disclose their ultimate owners, reliance on taxpayer incentives, and plans for water use and on-site power generation. Other states are following suit, with Pennsylvania recently signing an executive order for stricter permitting and disclosure rules.

Utilities that have implemented financial guardrails have seen speculative demand fall away. Key examples include:

• Chicago-based Exelon reduced its high-probability data center demand forecast by about 40% to 11 gigawatts after imposing stricter collateral requirements.
• AEP Ohio saw its data center power demand pipeline drop by more than half after the state introduced measures like grid connection study fees of up to $100,000.

Grid Stability and Cost Implications

The uncertainty surrounding data center demand creates a dual risk for the power grid: under-building could threaten reliability, while overbuilding for projects that never materialize could leave consumers paying for unneeded infrastructure. Tyson Slocum, director of the Energy Program at Public Citizen, noted that Texas's move aims to "create some order, and impose some transparency, on an industry that in much of the country is still like the Wild West."

The surge in demand is already impacting consumer costs. In the PJM Interconnection, the nation's largest grid, growth in data center demand contributed to a $29.4 billion increase in capacity costs for homes and businesses, according to grid monitor Monitoring Analytics. Even after filtering out speculative requests, utilities face a significant challenge. "The reality is that the load is showing up, and generation is not at the pace we need it to," said PJM spokesman Jeff Shields.
