Oncor weighs impact of Texas data center freeze on nearly 300-GW load pipeline

Texas Gov. Greg Abbott has paused approval of new data center connections to the state's power grid while officials audit the process. That freeze has put a hold on plans by Oncor, the big Texas grid operator, to review a wave of huge electricity requests from data centers and other large users. Oncor's parent company, Sempra, says it supports the pause, even though it creates uncertainty for a pipeline of projects that grew to nearly 300 gigawatts (a measure of electric power) in the most recent quarter.

Why this matters for your home: data centers are competing for space on the same power grid your house draws from. Utilities have been building new transmission lines and power plants to serve this growing demand, and those costs eventually show up in electric bills. Oncor already got approval this year for a $560 million increase in what it charges through base rates, which took effect June 1. Company executives say any costs tied to serving the paused data center requests won't be added to their spending plans until at least 2027, so there's no immediate new charge tied to this freeze. But the episode is part of a broader pattern: as data centers strain the grid in Texas and elsewhere, the debate over who pays for new power infrastructure, and how fast it gets approved, is likely to keep shaping electricity rates for ordinary homeowners in the coming years.
