Day-Ahead Market Enhancements Initiative Update, Call 5/2/19

MESSAGE

The California ISO has scheduled a stakeholder call on May 2, 2019 to discuss next steps for the Day-Ahead Market Enhancements initiative.

 

The ISO conducted a thorough review of stakeholder comments received on the recent proposals issued for both phases. As a result of both implementation complexity and stakeholder comments, the ISO is proposing to revise the scope of this initiative.

 

Phase 1 of this initiative focused on moving from hourly to 15-minute scheduling granularity in the day-ahead market. After further evaluation of the benefits relative to implementation complexity, the ISO is deferring consideration of day-ahead market 15-minute scheduling.

 

As proposed in phase 2, the ISO will continue the development of a flexible ramping product to address uncertainty that can materialize between the day-ahead and the real-time markets. However, the ISO proposes to defer the other scoped elements included in this phase.

 

The ISO will discuss these scope changes during the May 2 call.

 

Additional information about this initiative, including stakeholder comments, can be found on the ISO website at http://www.caiso.com/informed/Pages/StakeholderProcesses/Day-AheadMarketEnhancements.aspx. An agenda and presentation will be available prior to the call at this same link.

 

This call will be recorded and the video file 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.
