Market Update calls: Time extended, opportunity to submit questions in advance

The California ISO will extend the duration of the upcoming Market Update calls on May 14 and May 28, 2026, to provide additional time to discuss market performance following the Extended Day-Ahead Market go-live. Each call will be extended to two hours.

Stakeholders are encouraged to submit questions ahead of each call using the comment template available on the Extended day-ahead market Initiative webpage. The comment template will remain open until May 27, 2026. Questions received will help inform the discussion topics for the upcoming Market Update calls. Due to timing and the volume of inquiries, the ISO may not be able to address all questions during a single call but will work to address as many as possible across the upcoming sessions.

The ISO will continue to use existing forums to provide updates and respond to stakeholder questions. In particular, stakeholders are encouraged to direct settlement-related questions to the bi-weekly Settlement Users Group (SUG) meetings, where the ISO will provide updates on settlement statements, known issues, and related analysis. The settlement statement for trade date May 1, 2026 is scheduled to be published on May 14, 2026. Additional discussion and updates on settlement results are expected during the May 20, 2026 SUG meeting.

The ISO appreciates stakeholder engagement and looks forward to continued discussion through these forums.
