A streamlined process for interconnecting generating facilities

The generation interconnection planning process helps power plants interconnect to the ISO grid. We provide information and resources to help you understand and comply with requirements.

 

Process and requirements

Requirements and resources for Generating Facilities seeking interconnection with the transmission grid in the California ISO Balancing Authority Area.

Generation participation

Technical bulletins

These bulletins are provided to communicate complex and technical information for the convenience of our participants. 
Use of technical bulletins is subject to the ISO website Terms of Use.

Qualifying facilities

Existing qualifying facility owners entering into interconnection agreements must submit affidavits attesting to their capability and that electrical characteristics will remain substantially unchanged.

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.

Deliverability methodology

Generator Interconnection and Deliverability Study Methodologies training provided a forum for market participants and other interested parties to gain an understanding of the ISO generation interconnection and deliverability study methodologies.
