9 p.m. – The period of conserving energy has passed and the grid has returned to a comfortable reserve capacity. Thank you to everyone who was able to cut back power use this evening.
Please note that tight grid conditions are projected to persist in the evenings through the weeken, and additional calls for conservation may be required.
As the extreme heat and low wind conditions persist today and into the weekend, we have a repeat of electricity generation conditions that will require conservation efforts to keep things in good shape again today. The Electric Reliability Council of Texas has issued a request for Texans to conserve power 3-9 p.m. this evening as electricity demand remains high into the evening and solar production drops off, creating very tight grid conditions. When demand is too much for available generation, rolling outages can occur to prevent damage to the grid.

ERCOT Expects Tight Grid Conditions, Requests Conservation Today from 3pm to 9pm CT (Austin, TX) – Due to continued low wind-power generation and high demand, operating reserves for ERCOT are expected to be low in the afternoon and evening. As a result, ERCOT is asking Texans to conserve electricity use, if safe to do so, today from 3 p.m. – 9 p.m. CT. We expect these conditions to persist through the weekend because of extreme heat and ask Texans to stay tuned for additional communications this weekend.
Yesterday, ERCOT avoided emergency operations due to the conservation efforts by Texas residents and businesses, combined with timely rainfall in the Houston area, improved wind conditions, and additional grid reliability tools.
Similar to yesterday, today’s conservation appeal does not indicate ERCOT is experiencing emergency conditions at this time. Current forecasts are showing a potential to enter emergency operations this evening because of expected low wind-power generation and high demand. ERCOT will continue to closely monitor conditions throughout the day and will keep the public informed through our communications channels.
ERCOT is requesting all government agencies (including city and county offices) to implement all programs to reduce energy use at their facilities.
ERCOT continues to use additional tools to manage the grid reliably, including using reserve power, calling upon reductions by large electric customers that have volunteered to lower their energy use, and bringing more generation online sooner. ERCOT is also working with out-of-state Independent System Operators (ISOs) and Market Participants to obtain additional power generation capacity.
Conservation is a widely used industry tool that can help lower demand for a specific period of peak demand time, which is typically late afternoon into the evening hours. Energy-saving tips can be found on the TXANS webpage at ercot.com/txans.
If you are experiencing an outage at this time, it is local in nature and not related to overall grid reliability. Please check with your local electric provider for more information.
Why the Request to Reduce Usage?
- Extreme Heat. Continued statewide extreme temperatures.
- Record Demand. Texas continues to experience near-record demand due to the heat.
- Wind. Wind generation is forecasted to be lower this afternoon/evening and throughout the weekend during peak demand time.
- Solar. Solar generation declines into the evening hours, before completely going offline at sunset.
Peak Demand
- ERCOT set a new, all-time, unofficial peak demand record of 85,435 MW on August 10, 2023.
- In 2022, the August peak demand was 78,465 MW.
- This summer, ERCOT has set 10 new all-time peak demand records.
- Last summer, ERCOT set 11 new peak demand records with a high of 80,148 MW on July 20.
