INITIATIVE:
Day-ahead market enhancements archive

Started: Mar 07, 2018

Leads
Megan Poage

The ISO has deferred phase 1 of this initiative after determining the complexity of implementing 15-minute scheduling in the day-ahead market would outweigh the benefits. The ISO will continue the development of a new day-ahead product as proposed in phase 2 of this initiative, with consideration of necessary policy changes due to the deferral of phase 1.
