Tariff Clarifications Summer 2025: Clarifications matrix and draft tariff language posted; call on 7/11/25

The California ISO will hold a public stakeholder call on July 11, 2025, to discuss a series of draft tariff language clarifications.

These tariff clarifications are intended to correct typographical errors, better align definitions and internal section references, as well as remove outdated language or processes previously addressed by the ISO.

A matrix describing the draft tariff language and individual reasoning for each of the proposed revisions is available on the Tariff Clarifications Filing – 2025 webpage.

This meeting will be recorded, and the video file will be posted on the initiative webpage for a limited time. The recording is for informational and convenience purposes only and any related transcriptions should not be reprinted without the ISO’s permission.

Please submit written comments on the draft tariff language by end of day July 9, 2025, through the ISO’s commenting tool using the link on the process webpage.
