Resource data template

Generation developers must submit this document to ResourceData@caiso.com for review and as part of the generator interconnection process.
  • Resource data submission
    The Generator Resource Data Template and the Intertie Resource Data Template are used to submit requests to add or change specific operating parameters that reside in the Master File. For updates to existing data, scheduling coordinators must make any changes on the templates downloaded from the Master File user interface or application programming interface. Scheduling coordinators then submit updated templates using the user interface UPLOAD function or the programming interface SUBMIT services. Requests for new system resources should be sent to RDT@caiso.com in the New Intertie Resource Request template.
