Interconnection Process Enhancements 2023: Final Revised Addendum to Final Proposal Posted

The California ISO has posted a final revised addendum to the Interconnection Process Enhancements 2023 final proposal to the initiative webpage.

This addendum provides additional clarifications on the final proposal for stakeholders, based on the most recent round of comments. The addendum addresses the following issues:

• Clarification of the implementation of the zonal approach, and how available transmission capacity will be assessed for each cluster.
• A commitment to monitoring the results of various components of the interconnection request intake process and coordinating with the California Public Utilities Commission (CPUC), local regulatory authorities, and stakeholders to adjust any necessary components for Cluster 16 and future clusters.
• A requirement that load-serving entities (LSEs) opt-in to the LSE allocation process and post selection criteria and contact information on a publicly-accessible website, in order to improve the transparency and rigor of the LSE allocation process while respecting oversight of LSE procurement activities.
• Clarifications to the scoring process, and recommendations to stakeholders on the LSE allocation process.
• Further clarification of the treatment of mixed-fuel resources such as hybrid and co-located solar and storage projects.
• Clarifications to the engineering design plan scoring criterion.
• Context and rationale for the final proposal’s treatment of Energy Only resources.

We are providing this addendum in response to stakeholder requests for clarification and in preparation for the June 12, 2024 Board of Governors decision on this proposal.
