The Texas Supreme Court ended litigation against power generators following the 2021 winter storm, which left tens of thousands of Texas citizens and small businesses seeking billions of dollars in damages. The decision is a significant victory for large power generators such as Luminant, NRG, Calpine, Exelon and Sempra Energy who argued that the lawsuits should be dismissed as the weather, not the companies' actions, was responsible for the injuries and damages. In rejecting an appeal by lawyers for the victims, the court left intact a December 2023 ruling by the First Court of Appeals stating that the suits had no basis in law or fact. The only remaining lawsuits brought by storm victims are those against Texas distribution utilities, Oncor.
