Determine the project path based on project type to create your new resource interconnection project code Review New Resource Implementation Guide
Review New Resource Implementation Checklist
Follow the guide to ensure a smooth transition from build to bid in the ISO markets
The checklist provides requirements based on project type.
Once your project is created any inquiries can be sent to NRI@caiso.com
. Please include the ISO project code in the email subject line.
The ISO "Bucket" system is derived from the generation project estimated Sync/Implementation date and specifies interconnection deliverable acceptance deadline dates. ISO review and approval requires 10 days from the time a generator owner submits a deliverable. If a deadline date is not met, document processing stops and a new implementation date must be established.
Planning - 203 days before sync
Bucket 1 – Full network model preparationThe following deliverables are required to create an ISO market Resource ID and to be modeled in the Full Network Model (FNM). These documents are essential for participation in ISO markets, plus documents to forecast and model the resource in ISO real-time and market systems. These bucket items must be submitted in advance of the bucket acceptance due dates.
Implementation - 105 days before sync
Validation - 30 days before sync
Trial operations approval - 10 days before sync
Bucket 4 – Trial operations approvalTrial operations testing includes preliminary validation of meter data. Buckets 1 through 4 deliverables must be completed and accepted in order to request to synchronize to the grid. This Request can take up to 10 business days to complete. Metering and telemetry Point to Point testing must also be successfully completed. Final validation of metering and telemetry data will be conducted after synchronization using actual generation data.
Trial operations - 1 day before sync
Bucket 5 – Trial operationsThe interconnection customer’s scheduling coordinator must contact ISO outage management 24 hrs. in advance of initial synchronization and again immediately before synchronization at the following numbers:
Ops Planning North: 916-351-2206
Ops Planning South: 916-351-2215
The SC must also contact the ISO real time generation desk at 916-351-2488 for initial and all subsequent synchronization and testing. The Real Time desk can fully or partially curtail trial operations at any time.
Bucket 6 – Commercial Operation Date (COD)The ISO will issue a signed COC following metering and telemetry validation with live test generation data and approval of all required documentation. This certificate must be issued before declaring a commercial operation date.
All Bucket 1 through 5 and MSVS must be received and accepted in order for the IC can request COD or COM. This Request can take up to 5 business days to complete. The ISO will issue an email response containing the date the interconnection customer is complete with the NRI process. Once this email is received, then the IC will need to complete the COD Declaration or COM Declaration and upload into RIMS with an effective date. Please review the NRI Guide for more detailed information on the COM/COD process.
