2026 and 2030 Local Capacity Technical Study Base Cases posted, comments due 1/30/25

The California ISO Tariff requires the ISO to engage in a transparent and collaborative process while performing its 2026 and 2030 Local Capacity Technical Studies. As part of this collaborative process, the ISO and stakeholders agreed that the ISO will publish initial base cases on or about Jan. 15, 2025. These initial 2026 and 2030 base cases are now available on the ISO Regional Transmission secure website.

Interested entities must complete, execute and submit the Regional Transmission Non-Disclosure Agreement (NDA), and the Western Electricity Coordinating Council (WECC) Confidentiality Agreement to gain access to the secure website. These documents and other criteria for accessing the secure website are available on the Transmission Planning webpage, under the Accessing transmission data heading.

Entities may submit written comments on the base cases to regionaltransmission@caiso.com by close of business Jan. 30, 2025.

The 2026 Local Capacity Requirements Final Study Manual is available on the 2026 Local Capacity Requirements Process webpage.
