HOUSTON—Texas’s largest and oldest electric power cooperative on Monday filed for bankruptcy protection in federal court in Houston, citing a disputed $1.8 billion bill from the state’s grid operator.
Brazos Electric Power Cooperative Inc, which supplies electricity to more than 660,000 consumers across the state, is one of dozens of providers facing enormous charges stemming from a severe cold snap last month. The fallout threatens utilities and power marketers, which collectively face billions of dollars in blackout-related charges, executives said.
