The primary objective of the workstream was to support FERC jurisdictional ISO/RTOs and other stakeholders as they change wholesale electricity market design, operations, and market clearing software to comply with the order. It covered topics related to wholesale market design and operation from the ISO/RTO perspective, including DER aggregation participation models, market rules for different services, and geographically broad aggregations.
Market Participation Model Design Considerations: Different types of heterogeneous DERAs face distinctive challenges and offer unique opportunities.
The feasibility assessment of geographically broad DER aggregations spanning multiple transmission nodes helped identify the benefits, such as increased resource participation and improved market performance, as well as the potential impacts on system reliability, dispatch, pricing, and settlement of resources. In addition, the proposals on DER aggregation locational requirements from different ISOs/RTOs were reviewed, and corresponding market and operational implications were presented.
