In response to stakeholder comments, the ISO is separating the topics currently being examined in the Day-Ahead Market Enhancements initiative into two initiatives. The first initiative will address necessary policy changes to move from hourly to 15-minute scheduling granularity. The second initiative will discuss combining the integrated forward market (IFM) and residual unit commitment (RUC) process into a single optimization, the day-ahead flexible ramping product, and improved reserve deliverability.
The next steps for the first initiative will be to post a second revised straw proposal followed by a stakeholder call to address 15-minute scheduling granularity. Details will be provided in a future market notice. The second revised straw proposal will outline the 15-minute granularity items identified in the July 2 workshop presentation.
The ISO is planning an update to the technical appendix describing the integrated IFM and RUC, the day-ahead flexible ramping product, and improved reserve deliverability. The ISO will discuss the schedule for this initiative during the next stakeholder call. The updated schedule will allow for additional consideration of the interactions with the current real-time flexible ramping product and address improvements in the deliverability of this product.
Details regarding these two initiatives will be communicated in future market notices. Click here for more information about the Day-Ahead Market Enhancements initiative.
