Power grids from Texas to the U.S. Midwest are at risk of blackouts if a prolonged deep freeze sets in this winter, regulators warned Thursday.

The main Texas grid could see a power shortfall of 37% in extreme conditions, the North American Electric Reliability Corp. said in a report, suggesting that the state isn’t prepared for another cold snap like the one that crippled its grid last winter. Two nearby electricity systems may also face tight supplies, according to the report.
