ERCOT News Release as of Sunday, July 10th 2022 (effective Monday, July 11th 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 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.
