Power demand reached a record high in Texas over the weekend as a strong heatwave swept parts of the state and other regions of the country.

The power grid demand on Sunday reached 75,000 megawatts at around 5:15 p.m. It exceeded the 74,820-megawatt record from August 2019, according to the Electric Reliability Council of Texas.

The National Weather Service had issued a heat advisory Sunday for a majority of Texas counties. The increase in demand comes as people are using their air conditioning units at an increased amount to stay cool in the triple-digit temperatures.

ERCOT ensured that it has enough supplies to meet demand. The company has run into issues in the past amid excessive heat where it has lost power to some of its facilities.

On Saturday, the heatwave caused several major cities to reach record-breaking temperatures. Las Vegas reached 109 degrees Fahrenheit, which broke its record for the hottest day on that date since 1956. Phoenix hit 114 degrees, which broke its record from 1918, and Denver was at 100 degrees, breaking its record from 2013, The National Weather Service reported.
