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.
Adopts implementation rules for a Microgrid Incentive Program that targets placement of community microgrids to support populations impacted by grid outages.

Provides the microgrid conceptual design methodology—system characterization and goal definition, identifying policy and regulatory constraints, defining the design basis threats, and identifying critical loads and infrastructure.
Decision and Order No. 37786 approving the microgrid Services Tariff (Phase 1)

Hawaii Public Utilities Commission (Commissioners of the PUC)
Stakeholder
Hawaiian Electric Company, Inc. (and Hawaiʻi Electric Light Co. and Maui Electric Co.) – the incumbent utilities required to implement the tariff ; prospective microgrid project operators (e.g., private developers or community organizations); the Division
A Hawaii Public Utilities Commission (PUC) decision and order that approved a microgrid services tariff for the Hawaiian Electric Companies. The tariff's purpose is to promote microgrid development and remove regulatory barriers so that microgrids can operate during emergencies. In this phase 1 order, the PUC eliminated certain constraints—for example, it removed a program size cap and operator fees and declined to impose standby charges—to encourage microgrids to serve customers during outages. The order established the framework for microgrid project agreements (including a standard hybrid microgrid agreement) and included an microgrid participants' bill of rights to ensure service and safety standards for customers. Outstanding issues (e.g., compensation for services in non-emergency periods) were deferred to a phase 2 proceeding.
State-of-the-Art Microgrid Control System for Avista’s Alternative Energy Fund Project

This case study describes the planning, design, development, testing, and validation of a microgrid control system (MCS) implemented for Avista's shared energy economy project. The MCS integrates protection, automation, and control schemes along with energy storage management and load-generation dispatch strategies. The study provides insights into the design considerations and challenges encountered in developing a state-of-the-art microgrid controller capable of managing complex energy resources and ensuring system reliability.
The IEEE 2030.8 standard introduces a set of testing procedures for the verification, quantification, and comparison of performance of microgrid controllers.
