The Electric Reliability Council of Texas (ERCOT) manages the flow of electric power to more than 26 million Texas customers, representing about 90 percent of the state’s electric load. As the independent system operator for the region, ERCOT schedules power on an electric grid that connects more than 46,500 miles of transmission lines and 710 generation units.
The Electric Reliability Council of Texas (ERCOT) is a nonprofit corporation subject to oversight by the Public Utility Commission of Texas and the Texas Legislature.
Before each season, ERCOT forecasts potential electricity demand and generation capacity. If demand is projected to exceed supply, ERCOT will call for energy conservation. If grid conditions do not improve, they will initiate their Energy Emergency Alert (EEA) system, a declaration of a statewide power emergency that could result in controlled outages. Controlled outages are controlled, planned service interruptions designed to ensure grid stability and prevent grid failure.
During an Energy Emergency Alert, CoServ complies with ERCOT’s directives, including shedding load to reduce electric demand (controlled outages). In most cases, these outages should only last 30 to 60 minutes per neighborhood.
