AUSTIN – Texas’ electric grid operator ERCOT set multiple new winter peak demand records Tuesday night and Wednesday morning.

The record is now 65,731 megawatts, set between 7 and 8 a.m. Wednesday. This is significantly higher than the record set during the cold snap earlier this month, which was 62,855* megawatts.

The temperature overnight in North Texas dropped into the teens and single digits with Lewisville at a low of 10 degrees Fahrenheit.

During this week’s winter weather event, ERCOT had sufficient generation and transmission resources available to keep up with demand. As always, ERCOT closely monitors system conditions and coordinates with generators and transmission operators to help ensure grid reliability.
