INITIATIVE:
Western EIM base schedule submission deadline

Started: Sep 23, 2020

Leads
Daniel Johnson

This initiative will examine moving the final base schedule submission for the operating hour to T-30. Current financially binding base schedules are finalized at T-40. This later submission deadline will ideally increase market efficiency due to more accurate modeling of physical flows in the 15-minute market. In this same initiative the ISO is also proposing to examine updating tariff rules and market system to allow for base schedules to include energy below a resources minimum load. This proposed modification will allow entities to more accurately capture the startup energy.
