AI Data Centers Strain US Grid as Texas and Louisiana Freeze New Builds

Texas and Louisiana just slammed the brakes on data centers. Texas enacted a moratorium on September 28, 2026, and Louisiana followed a day later on September 29 — a one-two punch aimed squarely at the power-hungry buildout that has been rewriting America's electricity map.

The backdrop is simple: AI data centers are eating electricity faster than anyone forecast. The Energy Information Administration expects record U.S. power consumption in 2026 and 2027, and utilities plus grid operators are already scrambling to keep up with demand that keeps outrunning their own projections.

Texas is where the strain shows first. Grid constraints are biting hard — PJM capacity auctions have hit their price caps, and the state's large-load queue is dominated by data center projects lining up for power that may not exist yet.

Observers have been watching the Texas Legislature, Governor Greg Abbott, ERCOT and the PUCT for exactly this kind of move. Legislative action or executive orders aimed at reliability concerns were seen as the trigger that would push the odds of a moratorium higher — and now the trigger has been pulled.

Louisiana followed the same script. Governor Jeffrey M. Landry and the state legislature had been under scrutiny over incentive structures for data centers, and any movement there was flagged as a signal that would shift market perceptions. The September 29 moratorium answered that question.

What happens next hinges on whether the demand surge and grid constraints keep colliding. Those two forces, running side by side, are what will shape regulatory responses in both states from here.
