Please see the below release from the Electric Reliability Council of Texas (ERCOT) asking Texans and Texas businesses to conserve electricity, Wednesday, September 6, between 6-9 p.m. Oncor is echoing this request 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) – Due to continued high temperatures, high demand, low wind, and declining solar power generation this evening, operating reserves are expected to be low into the evening hours. As a result, ERCOT is asking Texans to conserve electricity use, if safe to do so, today, September 6, from 6 p.m. – 9 p.m. CT.

Today’s conservation appeal does not indicate ERCOT is experiencing emergency conditions at this time. Current forecasts are showing a potential for low reserves this evening because of continued high temperatures, high demand, low wind, and declining solar power generation into the evening hours. 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?

1. Heat. Continued statewide high temperatures.
2. Demand. Texas is seeing high demand due to the heat.

1. Solar. Solar generation starts to decline earlier in the afternoon hours towards the end of summer before completely going offline at sunset.
2. Wind. Wind generation is forecasted to be low this evening during peak demand time.

Peak Demand

1. ERCOT set a new, all-time, unofficial peak demand record of 85,435 MW on August 10, 2023.
2. ERCOT set a new all-time September peak demand record of 81,674 MW on September 5, 2023, surpassing the previous September peak of 78,459 MW set on September 4.
3. This summer, ERCOT has set 10 new all-time peak demand records. 
4. Last summer, ERCOT set 11 new peak demand records with a high of 80,148 MW on July 20.
