​Consolidated Energy Imbalance Market initiatives

This new initiative combines three EIM initiatives from the ISO 2017 Roadmap. The initiative will investigate if third party transmission owners located between two EIM balancing areas (BA) can provide available capacity to these entities for EIM transfers.  It will also examine if current wheel through functionality can be used to manage bilateral schedule changes that either source or wheel across the EIM footprint.  And finally, this initiative will explore equitable sharing of benefits when an EIM transfer wheels through an EIM BA.



The ISO implemented effective November 1, 2018 the following EIM enhancements: 1) Markets to exclude flexible ramping provision of EIM Balancing Authority Areas (BAAs) undergoing contingency with a new OASIS report to display the real-time intervals where BAAs (EIM and ISO) are in contingency; and 2) ISO enhancements to Balancing Authority Area Operations Portal (BAAOP) EIM operator screens to review active market data and flexible ramping sufficiency test inputs for improved EIM operations.
