Gov. Greg Abbott asked the last remaining member of the Texas Public Utility Commission to step down on Tuesday.
In the 48-minute call, he said he would fight to keep billions of dollars from being returned to utilities that were forced to buy power at sky-high prices.
"You know San Antonio had some really big gas bills, a fairly large electric bill, but they have a lot of money, and they're fine," he said.
Municipal utilities — including CPS Energy — and retail electric providers are now struggling with massive bills, which they argue are unjustified.
The independent market monitor for the state's grid operator, ERCOT, also called the prices artificially inflated and recommended that billions of dollars be returned to purchasers.
