Texas Halts Data Center Grid Hookups Amid 474-GW Surge

A Grid Under Strain

Texas has hit pause on new data center connections to its power grid after the queue of proposed projects seeking access to the Electric Reliability Council of Texas (ERCOT) ballooned to a staggering 474 gigawatts — a figure that vastly outstrips the grid's actual capacity 1. Governor Greg Abbott ordered the halt directly, framing the move as a matter of putting residents first: "Texans must come first," he said, while also pushing to restrict new data facilities from setting up in rural parts of the state 3. The decision underscores a growing tension between the artificial-intelligence-driven data center boom and the physical limits of the power infrastructure meant to support it.

Transparency Problems Compound the Crunch

Part of what triggered the freeze in Texas was not just the sheer volume of requests but a lack of accountability behind them. Regulators found that only 28 of 377 companies seeking grid connections had actually complied with disclosure requirements meant to verify the legitimacy and scale of their projects 1. That gap suggests many of the megawatt figures piling up in ERCOT's interconnection queue may be speculative, overlapping, or otherwise unreliable — making it harder for grid planners to distinguish real demand from placeholder requests filed to secure a spot in line.

The Problem Isn't Unique to Texas

Similar strains are showing up nationally. PJM Interconnection, which manages the grid across Pennsylvania, New Jersey, Delaware, and other states, has warned it could face a shortfall of roughly 6,800 megawatts by the 2028-29 timeframe as data centers and industrial expansion push demand upward faster than new generation can be built 2. In response, PJM is pursuing greater transparency of its own, proposing a registry that would track facilities drawing more than 50 megawatts of power — an effort to get ahead of the same kind of murky, hard-to-verify demand signals that tripped up Texas regulators 5.

Going Around the Grid Entirely

Faced with strained public utilities and lengthy interconnection wait times, a significant share of the industry is simply bypassing the grid altogether. Roughly 40% of new data center capacity additions are now expected to be powered entirely off-grid, typically through dedicated natural gas generation built on-site 4. That trend reflects both the urgency driving data center construction — largely fueled by AI computing needs — and a tacit acknowledgment that traditional grid operators cannot keep pace with the timelines developers want.

Why It Matters

Taken together, these developments point to a broader reckoning: the electricity demands of AI and cloud computing are colliding with grid capacity limits, regulatory oversight gaps, and long infrastructure build-out timelines. Whether through moratoriums like Texas's, shortfall warnings like PJM's, or the retreat to off-grid generation, utilities and policymakers are signaling that unchecked data center growth can no longer be absorbed without structural changes to how power demand is verified, planned for, and built out.
