ERCOT surpasses 70,500 MW, breaks hourly peak demand records set earlier this week
Austin, TX, Aug. 10, 2016 — For two consecutive hours today, ERCOT systemwide demand surpassed the previous record set Monday, Aug. 8.
Peak demand reached 70,531 megawatts (MW) between 3 and 4 p.m. and then blew past that new record with 70,572 MW of demand between 4 and 5 p.m. This tops Monday’s record by 403 MW.
"We’re pleased that the system continues to perform well as the need for air conditioning drives up demand," said Dan Woodfin, director of System Operations. "These hot summer days always put our grid to the test, and we have had sufficient generation available to carry us through these high-demand periods."
The current load forecast indicates the region may meet or exceed 70,000 MW in demand between 3 and 6 p.m. tomorrow as well. ERCOT works closely with its market participants to ensure there is enough generation and transmission resources available through peak demand hours.
"Based on current projections, we also don’t expect any issues tomorrow," Woodfin said. "That will depend in part on whether generation, including wind, remains available at levels similar to what we saw today."
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.
