Description: This PRR changes the Protocols Sections noted above and institutes an Emergency Interruptible Load Service (EILS) as a load interruption emergency backstop for use only during Emergency Electric Curtailment Plan (EECP) Step 3. EILS would be a merit order of loads that have voluntarily offered to interrupt at an offer price and would be dispatched to interrupt in the EECP step just prior to the Independent System Operator™s (ISO) dispatch order to Transmission and Distribution Service Provider/Distribution Service Providers (TDSP/DSPs) to shed firm load in order to preserve the syste€™s frequenc
Reason: In September 2006, ERCOT proposed the creation of an emergency interruptible load product incorporated into the EECP as an additional tool to manage system frequency and avoid firm load shedding.
