ERCOT sets new winter peak demand record

AUSTIN, TX, Dec. 19, 2016 – Nippy winter weather across Texas drove demand for electricity to a new winter record in the ERCOT region. Control room data recorded an hourly peak of 57,924 MW between 7 and 8 a.m. on Dec. 19, compared to the previous winter peak of 57,265 MW set Feb. 10, 2011.

This new winter record exceeds the previous December demand record of 53,642 MW (set Dec. 10, 2013 between 7 and 8 a.m.) by more than 4,000 MW. As the front blew into the state over the weekend, the ERCOT system also experienced a new record for instantaneous wind generation output. Wind output reached 15,195 MW at 6:20 p.m. on Saturday, Dec. 17, topping the previous record of 15,033 set Nov. 27, 2016.

*The new winter peak record was updated Jan. 9, 2017, to reflect final settlements. The previous figure listed was 57,958 MW.
