Houston – Aug. 17, 2023 – The Electric Reliability Council of Texas (ERCOT) has issued a Voluntary Conservation Notice and is asking consumers and businesses to safely reduce their electricity use as much as possible today from 3 p.m. to 8 p.m. due to extreme temperatures, forecasted high demand and lower reserves. CenterPoint Energy does not generate electricity itself, so any shortage of electric power capacity from the electric grid is not something that the company controls.
At this time, ERCOT is not experiencing emergency conditions. 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.
Consumers can help the ERCOT grid by conserving energy, especially during peak hours of 3 p.m. to 8 p.m. Please conserve electricity by:
- Raising your thermostat by a degree or two, if safe to do so.
- Set pool pumps to run early morning or overnight; shut off during peak hours.
- Use ceiling fans and portable fans to circulate the cool air.
- Close blinds and/or curtains on windows that receive direct sunlight.
- Shade air conditioning units or condensers located outdoors, if possible.
- Turn off and unplug non-essential lights and appliances.
If conditions worsen, ERCOT may issue a directive to curtail power delivered to customers, which requires transmission and distribution utilities like CenterPoint Energy to implement controlled outages due to power generation shortage. Controlled outages are planned emergency measures designed to avoid potentially longer and more widespread power outages for customers. There are three levels of Energy Emergency Alerts (EEA), and controlled outages are only implemented as a last resort to maintain reliability of the electric system, and they are done so with the intent to rotate outages in the electric service territory based on system conditions.
Houston-area customers should prepare now and have a back-up plan in place, especially those who rely on electricity for life-sustaining equipment.
ERCOT is the independent system operator for the region and manages the flow of electric power to most of Texas and more than 26 million Texas customers. CenterPoint Energy is an investor-owned electric utility and a member of ERCOT. The company manages the transmission and distribution of electricity to its approximately 2.7 million customers across the greater Houston area and surrounding communities.
As needed, CenterPoint Energy will continue to keep customers updated through the company's customer communication channels, including Twitter (@CNPalerts), Facebook, Power Alert Service, Outage Tracker (Estimated Restoration Times will not be available for these types of emergencies) and the web.
