Enroll DERs into a CAISO-registered VPP aggregation resource and submit a day-ahead schedule via the CAISO SIBR portal

Steps

1. Register as a Scheduling Coordinator (SC) with CAISO and configure a Supply-side DER Aggregation resource using the CAISO Resource Interconnection Management System (RIMS) portal
2. Submit the DER Aggregation resource registration with the Utility Distribution Company (UDC) coordination requirements: provide the PNode ID, CAIDReservation ID, and list of individual DER site IDs that form the aggregation
3. Obtain the Participating Aggregator agreement and configure the telemetry feed from the aggregated resource to CAISO's Energy Management System; confirm the resource appears in the CAISO OASIS resource list
4. Submit the day-ahead schedule via the SIBR API or CAISO scheduling interface: POST a SC_SCHEDULE transaction for the resource with hourly MW values for each hour-ending; use the correct ISO 8601 trading date format
5. Monitor the resource's real-time dispatch through CAISO's OASIS API: GET /oasis/singleZip?queryname=AS_RESULTS&market_run_id=RTM&startdatetime=... to retrieve real-time market results
6. Report measured output to CAISO through the metering telemetry channel at the required interval (typically 5-minute SCADA readings) for settlement under FERC Order 2222 participation rules
