Issue F What interconnection rules should the Commission adopt to account for the ability of DERMS and aggregator commands to address operational flexibility need? Related questions to consider: How are DERMS and Aggregation being used in other regions? How do we enable DER to increase operation flexibility through communications and aggregation, thus allowing customers to interconnect that previously could not? How do we do this now while waiting for DERMS roadmaps? 2

GS and DERMS examples in the US Market Hawaiian Electric Virtual Power Plant – Multiple strategies to increase operational flexibility peak demand shaving, load control on-demand reserve capacity Ancillary services ISO-NE – Grid Services Increase operational flexibility Capacity Ancillary services Connected Solutions in Massachusetts, Rode Island, New England Demand response of DER and Loads (EV) - increases opflex metrics for multiple utilities 3

Aggregator System Architecture

Typical Residential Aggregation DERMS (or other registered accounts) use existing telecommunications networks to talk to aggregators Aggregators use existing telecommunications networks to talk to DER Homeowners connect DER to Ethernet or cellular devices Aggregators do not own or operate these networks and network devices Residential Aggregator Option

The Inverter as the Lynchpin Smart inverters are well positioned to provide the required systematic flexibilities: Grid sensing, Smart Inverter functions Designed to mange production and consumption together, and therefore seamless and synchronized Cellular/Ethernet communications built in Advanced computing and memory capabilities No gateway required 8

Operational Flexibility Needs 9

Time Tables Customers need to interconnect DER to meet State goals now Beneficial grid services can address grid constraints on hosting capacity There are two timelines at play 2019 Private Sector - Real time aggregated control and data reporting of PV, Storage, EV and Home Energy Management. Services and Infrastructure exists today to manage many fleets without DERMS 2019-2024 - IOUs Need time to develop higher level DERMS as shown in roadmaps Proposed next steps – develop interconnection rules that allow aggregators to serve the immediate needs of the public and the IOUs now by leveraging existing communications and smart inverter functions that are already certified and deployed in fleets of inverters today 10

Visibility Into More Hosting Capacity Now SolarEdge Smart Inverter Fleet Admin for utilities Set and view smart inverter settings on fleets of inverters via simple point and click web user interface Set V/W, f/W, V/Var, Power factor See V, f, real and reactive power telemetry Available now. Licensed by North American utilities. No need to wait for DERMS, utilities can pilot smart inverter functions today Inform DERMS roadmap development through targeted pilots of planned use cases.
