The record demand for power from Texas' power grid was topped twice Wednesday, due in no small part to excessive triple-digit heat that remains in the forecast for the next several days.
The Electric Reliability Council of Texas (ERCOT) reports first record-breaking demand for power was set between 3 p.m. and 4 p.m. where statewide peak demand reached 71,438 MW (megawatts).
That record was broken again the next hour, when peak demand reached 72,192 MW, 25,469 of which was from the DFW-area.
Both numbers eclipsed the previous record of 71,110 MW set in August 2016.
With excessive heat warnings in effect Thusday and Friday, the record may be toppled several more times this week.
"Texans continue to deal with extreme heat across the state as ERCOT and electricity providers are working diligently to ensure they have the power they need to keep cool. We fully expect to keep hitting new demand records as summer 2018 continues," ERCOT said Wednesday.
Earlier in the week, ERCOT said operators are constantly monitoring the grid's condition to keep power flowing uninterrupted.
A single megawatt supplies enough energy to power roughly 200 homes during periods of high use.
ERCOT oversees 90 percent of Texas' power grid, powering about 24 million customers in DFW, Houston, San Antonio, Austin, Corpus Christi, Abilene and the Rio Grande Valley. A map of the ERCOT region can be seen here.
North Texas remains under a Heat Advisory until 7 p.m. Wednesday. An Excessive Heat Warning goes into effect at 1 p.m. Thursday and is expected to stay in place until 7 p.m. Friday.
