State regulatory opportunities to advance grid edge resource aggregations in wholesale markets

Stakeholder
State public utility commissions (regulators), distribution utilities, grid edge resource Aggregators, and RTO/ISO market operators – focusing on the interaction among these in compliance oversight.
Identifies how state regulators and utilities can enforce compliance for grid edge resource aggregators participating in RTO/Independent System Operator markets (under FERC Order 2222). It reviews the FERC Order 2222 compliance filngs of market operators and highlights remaining challenges in monitoring and enforcement, then outlines actions states can take to bolster reliability. For example, the report suggests that states establish provisions to penalize underperformance by grid edge resource aggregators when a distribution utility’s override of an aggregator’s dispatch leads to lost expected output. In other words, if a utility must curtail an aggregator’s resources for safety, the aggregator could face a performance penalty for failing to deliver contracted services when a distribution utility’s override of an aggregator’s dispatch leads to lost expected output. This creates an incentive for aggregators to coordinate closely with utilities to avoid overrides. The report also discusses frameworks for utility-aggregator coordination (such as communication protocols to give utilities override capability) and oversight measures to ensure aggregators comply with both market rules and distribution reliability needs. It emphasizes real-world enforcement—e.g., requiring aggregators to meet registration requirements, adhere to dispatch limits set in utility review processes, and face penalties or removal from programs if they don’t comply.

Stakeholder
State public utility commissions and regulated utilities in MISO/SPP states (mostly vertically-integrated utilities in Midwest/South regions) are the primary audience. Third-party grid edge resource aggregators (e.g., CPower, Voltus) and retail customers
Provides a technical framework for state regulators on integrating third-party grid edge resource aggregators into the distribution grid and coordinating with wholesale markets . It highlights key considerations (jurisdiction, registration/licensing, data governance, dual participation rules, dispute resolution mechanisms, etc.) for states that previously banned retail aggregators and are now revisiting those rules in light of FERC Order 2222 and evolving grid needs . The report includes implementation details such as tiered options for state action and examples of how various states handle aggregator oversight (e.g., setting up customer data access protections and processes to resolve utility-aggregator conflicts).

Utilities, third-party microgrid developers, community organizations, and regulatory bodies
This document discusses the economic considerations and regulatory challenges associated with implementing community microgrids. It emphasizes the importance of microgrid operating agreements that define the responsibilities and coordinated operations between utilities and third-party microgrid aggregators. Key aspects covered include protection, power quality, islanding control, design specifications, communications, IT management, and cybersecurity.

Stakeholder
Electric Distribution Companies in Connecticut (United Illuminating and Eversource Connecticut) must adapt their planning and investment processes; third-party grid edge resource developers gain new market opportunities; regulators (PURA) and stakeholders
Establishes a transparent, competitive procurement and evaluation process for Non-Wires Alternatives in Connecticut. In this 2022 decision, the Public Utilities Regulatory Authority (PURA) set out how the electric utilities must identify distribution system needs (e.g., overloaded substations or reliability issues) and solicit grid edge resource proposals as alternatives to building new infrastructure . It provides a cost-benefit framework to compare grid edge resource solutions versus traditional wires solutions to ensure that ratepayer benefits are maximized . The decision covers cost allocation and recovery by allowing utilities to recover NWA project payments and rewarding them for cost-effective grid edge resource deployments (while protecting customers by only approving projects that are cheaper or more beneficial than the wires option). It is an operational roadmap for utilities to integrate grid edge resources in distribution planning, including standardized benefit-cost analysis, competitive bidding, and contractual mechanisms to fairly pay grid edge resource providers.

The North American Electric Reliability Corp.’s strategy document addresses the reliability challenges of rapid Grid Edge Resource growth and the emergence of the grid edge resource aggregator role. It notes that grid edge resource aggregators, as introduced by FERC Order 2222, present “unique operational benefits and challenges” for grid planners and operators . NERC discusses potential new oversight: e.g., whether large grid edge resource aggregators should be registered entities for reliability standards compliance, and how to coordinate transmission-distribution operations as aggregations grow . It also flags cybersecurity concerns with aggregators controlling many distributed assets . This strategy guides how reliability rules might evolve to include grid edge resource aggregators.

A technical report introducing key concepts and use cases for adopting a “common” information-sharing model in power systems. It outlines how a standardized semantic data model (CIM) can facilitate data exchange—including exchanging power network models between utilities, integrating data between applications within a utility, and sharing market/operational data among market participants . The goal is to reduce custom interfaces and data silos by using a common vocabulary for grid assets and messages.
