AUSTIN – UPDATE: 8:55 p.m. ERCOT is ending the Energy Emergency Alert and returning to normal.
The energy emergency has ended. There is enough electric supply available to serve current demand on the grid. No action is needed. Thank you for your conservation efforts.
Original story below:
ERCOT has moved into Emergency Operations issued an Energy Emergency Alert Level 2 (EEA 2) to maintain reliability of the grid. Earlier today, ERCOT issued a conservation appeal from 6 – 9 p.m. CT; however, operating reserves are continuing to decline. At this time, there are no power outages associated with the ERCOT power grid. ERCOT will continue to monitor conditions and deploy all available tools as part of our reliability-first approach to operations. ERCOT continues to request Texans conserve electricity use.
When reserves on the system get low, ERCOT begins emergency operations using three levels of Energy Emergency Alerts (EEAs). These levels provide access to additional power sources only available during emergency conditions to protect the reliability of the electric system. Entering Emergency Operations does not mean that ERCOT is expecting to call for controlled power outages, which would affect all customer classes, including residential, commercial, and industrial. Entering Emergency Operations means that ERCOT has access to more power reserves that help prevent power outages.
An EEA 2 is issued when ERCOT’s operating reserves have dropped below 1,750 MWs and are not expected to recover within 30 minutes. Controlled outages have not been requested at this time, however, could become necessary if demand isn’t lowered or additional supply cannot be added from generators.
At this time, ERCOT is bringing all available generation online, releasing any remaining reserves, using demand response to lower electric demand. ERCOT is also working with out-of-state Independent System Operators (ISOs) and Market Participants to obtain additional power generation capacity. Additionally, ERCOT obtained Texas Commission on Environmental Quality (TCEQ) enforcement discretion, which allows a generator to extend its service/run-time/operations to help meet demand, if needed, to help maintain grid reliability.
If you are experiencing an outage at this time, it is not because of the ERCOT power grid, but is local in nature. Please check with your local electric provider for more information.
ERCOT has requested all government agencies (including city and county offices) to implement all programs to reduce energy use at their facilities.
You can find more information on EEAs here.
Factors leading to tight grid conditions include:
- Heat. Continued statewide high temperatures.
- Demand. High demand due to the heat.
- Solar. Solar generation starts to decline earlier in the evening hours before completely going offline at sunset.
- Wind. Wind generation is forecasted to be low this evening during peak demand time.
Critical Medical Needs Reminder
If you have medical needs, please contact your local electric utility and have a backup plan in case power reductions, or controlled outages, are needed later. Your local electric provider is responsible for managing the power reduction, or controlled outages, in your area.
What can You do?
You can use these use these energy-saving tips to lower your electric use during this peak demand time, if safe to do so. Simple steps such as lowering/raising your thermostat a degree or two, turning off extra lights, and not using large appliances such as washer, dryers and dishwashers, can help.
