Update 7:30 p.m. – Conservation efforts kept demand in check, and generation capacity was sufficient to cover the need through the heat of the day.  Higher wind generation is expected tomorrow, which should help alleviate some supply worries as high temperatures continue.

Anticipating tight energy supply with the widespread high temperatures, the Electric Reliability Council of Texas has called for Texans to reduce energy demand.

Please help by reducing energy consumption from 2 p.m. to 8 p.m.

ERCOT Issues Conservation Appeal to Texans and Texas Businesses

Appeal Effective Monday, July 11, 2022

AUSTIN, TX, July 10, 2022 – With extreme hot weather driving record power demand across Texas, the Electric Reliability Council of Texas (ERCOT) is issuing a Conservation Appeal, asking Texans and Texas businesses to voluntarily conserve electricity, Monday, July 11 between 2-8 p.m. ERCOT also issued a Watch for a projected reserve capacity shortage from 2-8 p.m. At this time, no system-wide outages are expected.

Conservation is a reliability tool ERCOT has deployed more than four dozen times since 2008 to successfully manage grid operations. This notification is issued when projected reserves may fall below 2300 MW for 30 minutes or more.

ERCOT encourages all electric customers to visit the Public Utility Commission’s (PUC) Power to Save or their electric provider’s websites to get important conservation tips. According to the PUC, ways to reduce electricity use during peak times include turning up your thermostat a degree or two, if comfortable, and postponing running major appliances or pool pumps during afternoon peak hours.

ERCOT continues to use all tools available to manage the grid effectively and reliably, including using reserve power and calling upon large electric customers who have volunteered to lower their energy use.


ERCOT emphasizes that the call for conservation is limited to the hours of 2-8 p.m.


Factors driving the need for this important action by customers:

  • Record high electric demand. The heat wave that has settled on Texas and much of the central United States is driving increased electric use. Other grid operators are operating under similar conservative operations programs as ERCOT due to the heatwave.
  • Low wind. While solar power is generally reaching near full generation capacity, wind generation is currently generating significantly less than what it historically generated in this time period. Current projections show wind generation coming in less than 10 percent of its capacity.


Under current projected scenarios, performance of the generation fleet Monday is:


  Installed Capacity Monday (7/11) Tightest Hour (2-3 p.m.) Percentage of Installed Capacity Available at Tightest Hour
Dispatchable 80,083 67,913 85%
Wind 35,162 2,698 8%
Solar 11,787 9,557 81%

Total forecasted demand is 79,671 MW.

Ways to reduce energy use:

Put off high-usage tasks like laundry, oven cooking, car charging etc. until later in the day.

Raise your thermostat to 78 degrees or higher.

Set water heaters to 120 degrees or less.
