Historic low temperatures result in new winter peak demand record for ERCOT region

AUSTIN, TX, Jan. 17, 2018 – ERCOT set multiple new winter peak demand records last night and this morning.

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

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.

Consumers may view real-time ERCOT grid conditions by downloading the ERCOT app or by visiting the home page of the ERCOT website (

The Electric Reliability Council of Texas (ERCOT) manages the flow of electric power to more than 25 million Texas customers -- representing about 90 percent of the state’s electric load. As the independent system operator for the region, ERCOT schedules power on an electric grid that connects more than 46,500 miles of transmission lines and 650+ generation units. It also performs financial settlement for the competitive wholesale bulk-power market and administers retail switching for nearly 8 million premises in competitive choice areas.

ERCOT is a membership-based 501(c)(4) nonprofit corporation, governed by a board of directors and subject to oversight by the Public Utility Commission of Texas and the Texas Legislature. Its members include consumers, cooperatives, generators, power marketers, retail electric providers, investor-owned electric utilities, transmission and distribution providers and municipally owned electric utilities.
