    ERCOT Breaks Peak Record Again, Tops 71,000 MW for First Time

    Austin, TX, Aug. 11, 2016 – For the third time this week, electricity use in the ERCOT market has broken yet another record by exceeding 71,000 MW in systemwide hourly peak demand. ERCOT’s demand reached 71,043 MW between 3 and 4 p.m. today and then topped out at 71,197 MW between 4 and 5 p.m. This exceeds Wednesday’s peak record by 625 MW.

    This is the sixth time this week that ERCOT has reached record levels of energy demand. ERCOT exceeded 70,000 MW for two consecutive hours on Monday, Aug. 8 and then surpassed those levels Wednesday, Aug. 10 during two consecutive hours.

    "Our grid operators have done an excellent job managing the high demand we’ve seen this week, while also maintaining system reliability," said Dan Woodfin, director of System Operations. "We appreciate the work generation and transmission owners have put into getting their facilities prepared for these record power demands."

    Beginning Friday and into next week, the current forecast anticipates less power consumption. As long as resources remain available when needed, ERCOT believes there will be sufficient generation. The grid operator will continue to monitor system conditions and will notify the public if there is a need for conservation.

    One MW is enough generation to serve about 200 homes during peak demand, which generally occurs between the hours of 3 and 7 p.m. on hot summer days. August is typically the hottest summer month in Texas, and demand usually increases during this time.
