ERCOT Energy Emergency Alerts

ERCOT (Electric Reliability Council of Texas) uses a multi-level alert system to maintain grid stability. Each Energy Emergency Alert Level requires electric providers to take steps to reduce the demand on the grid.  

Conservation Alert 

ERCOT may call upon consumers to take steps to conserve power. Users can help by turning their thermostats up 2 degrees between 3 and 7 p.m. Additional conservation tips are available on ERCOT's conservation page.

Conservation Needed—EEA 1 

EEA 1 (Energy Emergency Alert 1) gives ERCOT operators authority to call on all available power supplies, including power from other grids, if available. Under current pilots, some demand response resources also are available at EEA 1. 

Power Warning: Conservation Critical; Risk of Rotating Outages—EEA 2 

If the situation does not improve, ERCOT escalates warning to a Power Warning, which allows operators to drop large commercial/industrial load resources that have entered contracts agreeing to be interrupted during an emergency.  

Power Emergency: Rotating Outages in Progress; Conservation Critical—EEA 3

If the capacity shortage is not relieved using voluntary and contractual demand response, ERCOT moves to a Power Emergency and instructs utilities to reduce demand by dropping load through rotating outages to help prevent the risk of a statewide blackout.
