INITIATIVE:
Real-time settlement review

E3
Started: Aug 13, 2020

Leads
James Friedrich

The scope of this initiative is to identify and address any inappropriate cost shifting that may be occurring in ISO’s real-time market between the Western Energy Imbalance Market (EIM) balancing authority areas. This initiative is intended to fulfill the commitment the ISO made during the Real-Time Market Neutrality Settlement initiative to more comprehensively review real-time market settlements to identify any remaining inappropriate cost shifting.

Outcome: The ISO implemented the Real-Time Settlements project in two phases, the first being on May 1, 2021. The second phase went live on Nov. 1, 2021. Phase 1 delivered the settlement of the Base Energy Transfer System Resource (ETSR) at the unique pricing location LMP. It also delivered the modify bid cost recovery (BCR) transfer adjustment amount to be based upon (ETSR) export over ETSR export plus measured demand. Phase 2 clarified tariff language that involves a market rule change that will allow an EIM entity not to settle Unaccounted for Energy (UFE) for each EIM entity.
