Real-time settlement review

Started: Aug 13, 2020

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.
