The workstream covered topics related to coordination from ISO/RTO, distribution utility, transmission utility, DER aggregator, and electric retail regulatory authority perspectives. This included communication and process needs during situations that require coordination across multiple entities. A major driver for coordination is to reduce the cost and complexity of providing grid services from aggregations of DER while maintaining reliable system operation across both transmission and distribution systems. The motivation for coordination may be different for each stakeholder involved in a coordination framework. For example, ISO/RTOs may be motivated to coordinate to improve utilization or access of DER for wholesale market services. For distribution utilities, the motivation could be to ensure reliable and safe operation of the distribution grid. For aggregators, there could be motivation to avoid performance penalties or other reasons.
Reference Stakeholders and Interfaces.
The workstream provided comprehensive assessment of the coordination frameworks and parameters between stakeholders as specified in FERC Order 2222. Some of these characteristics are explicitly mentioned in the Order while others are implied but necessary or useful to be performed to meet other direct requirements. The coordination parameters or order requirements may be enforced at various timeframes, spanning from pre-event/registration through post-event/settlement following the provision of the service. Consequently, this workstream considered the coordination in three broad categories: before the event (pre-event), during the event (operational), and after the event (post-event).
