Tariff Clarifications Filing 2025: Clarifications matrix with draft tariff language posted, call on 3/28/25

The California ISO will hold a public stakeholder call on March 28, 2025, to discuss draft tariff language clarifications.

These minor tariff clarifications are intended to update tariff language to reflect existing policy. These include bidding rules for variable energy resources that have yet to establish a state-of-the-art forecast, confidential treatment of information exchanged as part of EDAM implementation, and confirming temporary eligibility for MIC for resources interconnecting via a Subscriber PTO.

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 March 26, 2025, through the ISO’s commenting tool using the link on the process webpage.
