Cluster 15 Cluster Study Reports expected to be published on 10/29/25; User Guide updated

Cluster 15 Cluster Study Reports are expected to be published Oct. 29, 2025, and will be available in GRIP.  The user guide has been updated to provide instructions to view the report and provide next steps.  This information can be viewed starting on page 41. 

Cluster Study Report Meetings are scheduled as follows; all times are Pacific Time

Pre-registration is required and will close 3BD before the meeting date. Register by following the link sent via GRIP for the study area(s) associated with your project(s).  If you do not receive an email containing a link via GRIP by 10/10, please email irinfo@caiso.com with your name, project name, and queue number. 

1. Entities need to have a Transmission Planning (TP) NDA on file, with Exhibit As for all participants.  If you attended a C15 scoping meeting earlier this year, your entity’s TP NDA is on file; please do not submit another.  However, please verify that all employees planning to participate in the C15 study meetings have provided individual Exhibit As.
2. Consultants engaged since the scoping meetings earlier this year also need to have their entity TP NDA on file (or provide the complete TP NDA packet if they do not already have one on file), including Exhibit As for their participating personnel, and Exhibit Cs reflecting any newly engaged client entities.
3. TP NDAs (and individual Exhibit As) will be verified 3BD before the meetings.  Only those C15 entities with Transmission Planning NDAs on file (including signed Exhibit As for all participating personnel) will be allowed to attend the upcoming C15 Zonal meetings.
4. Any new TP NDA documentation must be submitted by Oct. 22, 2025, to allow time for processing.  Registrants without valid TP NDAs and individual Exhibit As will be removed from the meeting list.
5. Link to the TP NDA template: To add personnel to your existing TP NDA, please provide just an Exhibit A for each person (extract from the template).
6. Submit TP NDA documentation, or direct any questions about the status of your (or your consultants') TP NDA documentation, directly to caisonda@caiso.com
