The Texas agency that regulates the state’s power utilities overstepped its bounds and kept power prices too high in the wake of a deadly 2021 deep freeze that led to widespread electricity outages, according to a Texas appeals court ruling on Friday.

The Public Utility Commission of Texas (PUCT) exceeded “limits on its power” by keeping prices at a cap of $9,000 per megawatt hour during the storm, which struck in mid-February two years ago, the Texas 3rd District Court of Appeals in Austin ruled.
