Summer 2025 Resource Visibility Data Request

The California ISO is requesting Scheduling Coordinators (SCs) for generating resources to provide contractual data for their resources for this summer. As discussed in the Resource Adequacy Modeling and Program Design Track 3A: Resource Visibility policy initiative, the ISO would like to get insight into the contractual status of its fleet of resources. As an interim measure for this summer, SCs are asked to submit to the ISO the contractual status of their resources that are on the NQC list and anticipate being on the NQC list during the summer if the data is available to the best of their knowledge at the time of data submission. This is a one-time submission for this summer, and the data should cover the categories listed below for the months of June to September of 2025. To ensure the data is of greatest value to the ISO in evaluating conditions for the summer, we request SCs make their best efforts to submit the data by June 25, 2025. 

Specifically, the ISO is requesting the scheduling coordinators for generating resources to report to the ISO what quantities of RA-eligible capacity falls into each of the following categories:

• Contracted to the ISO BAA LSE. This refers to RA-eligible capacity under a capacity contract to an ISO BAA LSE for the months of June to September of 2025.  This applies regardless of how the resource has been, or is planned to be, shown to the ISO on monthly RA supply plans for the months in question.
• Sold outside the ISO BAA. This refers to RA-eligible capacity that is under a capacity contract outside of the ISO BAA for the months of June to September of 2025.
• Not contracted. This refers to RA-eligible capacity that does not fit into either of the above categories.
