Energy storage and distributed energy resources - relevant market notices
Phase 4 will explore refinements to the distributed energy resource (DER) and storage participation models, as well as lower integration barriers for demand response resources. This initiative will also explore expanding the models to optimally capture their value, as well as leverage resource design attributes that support grid reliability and allow for multiple-use applications.
Energy storage and distributed energy resources phase 4 - papers and proposals
Phase 3 will continue to identify and evaluate opportunities for increased participation of transmission grid-connected energy storage and distribution-connected resources in the ISO market. Topics suggested by stakeholders in the ESDER Phase 2 initiative will also be addressed in this phase.

Energy storage and distributed energy resources phase 3 - papers and proposals
Effective November 1, 2018, this initiative provided three new types of demand response performance evaluation methods, clarified Station Power treatment for storage resources, and incorporated additional gas indices into the net benefits test calculation to reflect all real-time participation regions. The enhancements are anticipated to lower barriers and enhance the ability of energy storage and distributed energy resources to participate in the ISO market. The Phase 2 policy allowed for baselines to be performed and submitted by scheduling coordinators, resulting in all remaining demand response system (DRS) functionalities to be integrated into MRI-S (Market Results Interface – Settlements) and decommissioning of the DRS.

Phase 1 enhanced the ability of grid-connected storage and distribution-connected resources to participate in the ISO market. Improvements included the ability for submitting the state of charge as a daily bid parameter in the day-ahead market, as well as an option to not provide state of charge limits or not have the ISO co-optimize non-generator resources based on state of charge.
