Reminder: 2026 Flexible Capacity Needs Assessment Process Data Submission Deadline 1/15/25

The California ISO has posted the data request template to collect data for conducting its 2026 Flexible Capacity Needs assessment. Scheduling coordinators of load serving entities must provide the ISO with the variable energy resources contract data by end of day Jan. 15, 2025 using the template. The ISO encourages participants to submit any questions to FlexRA@caiso.com as soon as they arise to ensure a timely reply before the January 15 deadline.

Please submit the data request template using the Customer Inquiry, Dispute and Information (CIDI) ticket process with “2026 Annual Flex RA Submission” in the subject line. The template is available on the process webpage.

Please note that all renewable resources, whether they have an RA contract or not, are required to be included in the survey.

The ISO has put together a Flex RA Survey FAQ document based on previous year’s questions.  Please reference the following FAQ document to help guide accurate survey submittal. 

The ISO uses the assessment to determine the quantity of flexible capacity needed for the upcoming resource adequacy year and how this quantity is allocated to local regulatory authorities (see tariff section 40.10.1 for additional detail regarding the ISO study).

Late submissions are subject to a $500 per day penalty under section 37.6.1 of the ISO tariff.

Note: The Business Practice Manuals and ISO Tariff are the official records for due dates.
