Aggregators and third-party demand response providers (DRPs) will typically be notified of Day-Ahead events by 5 p.m. the day prior, and of Day-Of events shortly after the California Independent System Operator (CAISO) notice is issued.
Virtual power plant, vehicle-grid-integration, and non-residential aggregations have minimum dispatch hours and may be notified day-ahead or day-of in response to other forecasted or anticipated grid stress conditions, such as high locational marginal prices in the CAISO markets and extreme heat waves, to achieve the minimum dispatch hours.
Third-party DRP and Capacity Bidding Program (CBP) aggregator notifications are courtesy notifications. Third-party DRPs and CBP aggregators are solely responsible for monitoring CAISO notices themselves if they plan to participate.
