Please see the below release from the Electric Reliability Council of Texas (ERCOT) asking Texans and Texas businesses to voluntarily conserve electricity, Sunday, August 20,  between 7-10 p.m. Oncor is echoing this appeal for conservation in its role as the transmission and distribution company, or the poles and wires company that delivers electricity to many Texans. It does not own or operate power generation facilities, or sell, purchase or offer electricity retail services. Oncor will continue to follow direction from ERCOT.

(Austin, TX) – ERCOT is asking Texans to voluntarily reduce electricity use, if safe to do so, due to extreme temperatures, continued high demand, and unexpected loss of thermal generation. This Voluntary Conservation Notice is in effect today, August 20, from 7 p.m. – 10 p.m. CT.

The Voluntary Conservation Notice is part of ERCOT’s Texas Advisory and Notification System (TXANS), alerting the public of grid conditions.

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.

Energy-saving tips can be found on the TXANS webpage at ercot.com/txans. 

Peak Demand

• ERCOT set a new, all-time, unofficial peak demand record of 85,435 MW on August 10, 2023.
• Yesterday, ERCOT set a new all-time weekend peak demand record of 84,805 MW.
• 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. Continued statewide 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.
• Generation. Unexpected loss of thermal generation.
