Texas' electric-grid managers told residents to reduce electricity usage "as much as possible" through June 18 as several of the state's generators faced outages.

Generators creating roughly 15% of Texas' power are in need of repair, according to a press release from the Electric Reliability Council of Texas (ERCOT). More than 70% of generators facing outages are thermal-based, meaning they are reliant on coal, gas, or nuclear energy to generate power.

ERCOT said Monday's peak-load forecast on the electrical grid may exceed 73,000 megawatts, which would surpass the peak demand set in the February freeze of 69,692 MW. According to ERCOT, the highest peak-demand record for the grid is 74,820 MW, which occurred in August 2019. For reference, 1 MW can power about 200 homes during the summer.

The state's grid is also facing strains because wind-generated power is "roughly 1,500 MW lower than what is typically available for peak conditions," ERCOT said, though it added that experts expected wind output to increase throughout the week.

"We will be conducting a thorough analysis with generation owners to determine why so many units are out of service," Woody Rickerson, ERCOT's vice president of grid planning and operations, said. "This is unusual for this early in the summer season."

The highs in Texas are expected to hit at least 100 degrees Fahrenheit during ERCOT's proposed period of energy conservation.

ERCOT faced a bevy of criticism for a massive blackout that hit much of the state in February, which led to an estimated 700 deaths, according to a BuzzFeed analysis, and the "biggest epidemic of CO poisoning in recent history" as families tried to stay warm amid freezing temperatures, according to a ProPublica report.

After signing two bills in June, Gov. Greg Abbott said that "everything that needed to be done was done to fix the power grid in Texas."

Texas state Sen. Kelly Hancock said in June that the Legislature's mission was to prevent February's blackout from reoccurring.

"Our ultimate goal was to make sure that those individuals, those consumers, our constituents back home, never ever had to deal with this issue ever again," Hancock said.

Despite the intentions of the Texas Legislature, ERCOT's website shows that energy prices are skyrocketing as the state electric grid becomes more and more reliant on its reserves.

ERCOT provided a few tips for Texans to reduce their electric use:

  • Set thermostat to 78 degrees or higher as "every degree of cooling increases your energy use by six to eight percent."

  • Turn off all unused lights and pool pumps.

  • Refrain from using large, high-energy-use appliances like washing machines, ovens, and dryers.

  • Turn off and unplug anything unnecessary.
