Events are triggered by the “Energy Emergency Alert (EEA)” process defined by the California Independent Service Operator Operating Procedure 4420.
Day-ahead events are triggered by CAISO EEA Watch notifications, and Day-of events are triggered by CAISO EEA Watch and EEA-1, EEA-2, or EEA-3 notifications. Base Interruptible Program participants are only eligible for compensation for ELRP events that overlap with BIP event periods, and only the incremental reduction below the BIP pre-committed Firm Service Level (FSL) during the overlapping event window is compensated under the ELRP.
SCE reserves the right to dispatch virtual power plant, vehicle-grid-integration, and non-residential aggregations outside of the EEA system in response to forecasted or anticipated grid stress conditions to meet the minimum event hour requirements for these subgroups.
