Emergency Interruptible Load Service

ERCOT procures Emergency Interruptible Load Service (EILS) by selecting qualified Loads to make themselves available for interruption in an electric grid emergency. EILS is an emergency load reduction service designed to decrease the likelihood of the need for firm Load shedding (a.k.a, “rolling blackouts”). Customers meeting EILS criteria may bid to provide the service through their qualified scheduling entities (QSEs). EILS is authorized by Public Utility Commission Substantive Rule §25.507.
