Resource Interconnection Guide

This guide is an overview of the basic requirements a resource must complete in order to interconnect to the ISO grid and participate in our Market. If you are new to the ISO and would like to learn about what the ISO does and how our market works please register for the Welcome to the ISO training course.

Getting Started


 

Getting Started
Understand what the ISO Balancing Authority is, learn what transmission is under ISO operational control or under utility control, determine whether the ISO’s interconnection process is the appropriate path for your interconnection, determine which interconnection option to pursue and learn about additional processes necessary to sell power to the grid.

ISO Interconnection market participant details

 

Interconnection Application - Study Options
Available study processes, how to apply for interconnection, and requirements for a valid application. (interconnection request, site exclusivity documents/deposit, study deposit, technical data).
(Suggested audience: Transmission-level interconnected facilities)

 

Interconnection Timeline and Study Process 
What to anticipate during the interconnection process, including an overview of timing, what to expect from joint meetings, requirements for posting financial security, and the impacts of a withdrawal on refunds.
(Suggested audience: Transmission-level interconnected facilities)

 

Studies, Study results, and Project Cost Responsibility
Study reports, resource adequacy deliverability studies and options, impacts on affected (neighboring) systems, and the relationship between generation interconnection and the ISO’s transmission planning process.
(Suggested audience: Transmission-level interconnected facilities, Distribution-level interconnected facilities, QF Conversions, Repowering Facilities, and Capacity increases)

Agreements and Queue Management
Contracts and documents required by the ISO, the negotiation process, queue management, monitoring and reporting of project progress, and the process for managing project changes.
(Suggested audience: Transmission-level interconnected facilities, Distribution-level interconnected facilities, QF Conversions, Repowering Facilities, and Capacity increases)

Resource Implementation and Market Modeling
Requirements for incorporating projects into the ISO market model including documentation, data and communication standards, testing requirements, connectivity and modeling requirements for projects electing to participate in the ISO energy and ancillary markets or programs (e.g. Regulation, PIRP, etc.). This includes QFs with expiring grandfathered contracts that intend to export energy.
(Suggested audience: Transmission-level interconnected facilities, Distribution-level interconnected facilities, QF Conversions, Repowering Facilities, and Capacity increases)

Metering and Telemetry
Requirements for obtaining a Certificate of Compliance for ISO metering and telemetry, including the design approval process and milestones, information submittals, and certain best practices. Options for enrolling in WREGIS reporting (for renewable energy credits).
