Extended Day-Ahead Market: Revised draft tariff language posted, call on 7/26/23

The California ISO has posted the Extended Day-Ahead Market (EDAM) revised draft tariff language documentation, and scheduled an associated public stakeholder call on July 26, 2023. The revised draft tariff language documentation is available on the EDAM initiative webpage.


In order to concurrently file both the EDAM and DAME tariffs with FERC and provide additional time for development of the tariff with stakeholders, the ISO has moved the filing date for both tariffs to mid-August. Submitting both EDAM and DAME to FERC in mid-August 2023 will support reconciliation of the DAME and EDAM tariffs in a clear and efficient manner and provide a more effective presentation of the two proposals.


The call will be recorded and the video file posted to the initiative webpage linked above for a limited time. The recording is for informational and convenience purposes only. Any related transcriptions should not be reprinted without the ISO’s permission.


Please submit written comments on the revised draft tariff language documentation by end of day June 30, 2023, through the ISO’s commenting tool using the link on the initiative webpage.
