ERCOT Issues Voluntary Conservation Notice

Effective Today, August 17 from 3 p.m. – 8 p.m. CT.
(Austin, TX) – ERCOT is asking Texans to voluntarily reduce electricity use, if safe to do so, due to extreme temperatures, forecasted high demand, and lower reserves. This Voluntary Conservation Notice is in effect today, August 17 from 3 p.m. – 8 p.m. CT. 

The Voluntary Conservation Notice is part of ERCOT’s Texas Advisory and Notification System (TXANS), alerting the public of grid conditions. Last week, ERCOT extended the Weather Watch through August 18 due to forecasted higher temperatures, higher electrical demand, and the potential for lower reserves. 

ERCOT is requesting all government agencies (including city and county offices) to implement all programs to reduce energy use at their facilities.

ERCOT is not experiencing emergency conditions at this time. Voluntary 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.

ERCOT is using 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.

If you are experiencing an outage, it is local in nature and not related to overall grid reliability. Please check with your local electric provider for more information.

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.

Why the Request to Voluntarily Reduce Usage?

  • Extreme Heat. Much of Texas is seeing a return to extreme temperatures today.
  • Record Demand. Texas is seeing near-record demand due to the heat.
  • Solar. Solar generation declines into the evening hours, before completely going offline at sunset.
  • Wind. Lower wind generation is forecasted for this afternoon during peak demand time.
