Integrated System Resilience

The reliability and resilience of the energy system is drawing increasing levels of attention from state regulators. While reliability is a broadly accepted term with well-defined metrics, resilience—the ability of the system to anticipate, absorb, recover from, and adapt to disruptive events, particularly high-impact, low-frequency events—is not yet incorporated into regulatory processes. NARUC is undertaking efforts to support state regulators’ approaches to defining and quantifying the benefits of resilience investments that reduce the likelihood, duration, and impacts of interruptions to electricity service.

NARUC staff experts who support these activities include:

  • Energy Resilience Reference Guide
    The NARUC Energy Resilience Reference Guide is envisioned as a one-stop primer for state public utility commissions (PUCs) to assist in the development of a shared language, valuation framework, and educational tool on the topic of energy resilience. The resilience of the energy system has increasingly become part of commissions’ regulatory scope so informed decisions are made regarding how to best enhance system resiliency. Several states have already established evaluative resilience criteria (via legislative statute or regulatory directive). This guide will summarize many of the critical topic areas within energy resilience and facilitate adoption of resilience valuation frameworks by which PUCs can weigh investment decisions regarding energy system resiliency. This guide is intended to encourage state PUCs to develop their own frameworks that align with existing resources and to provide topical information related to enhancing system resilience to extreme weather, cyber-attacks, a changing energy landscape, and other threats to critical infrastructure. This guide will also assist in continual assessment of new policies and regulations designed to enhance energy system resilience.
  • Advancing Electric System Resilience with Distributed Energy Resources: A Review of State Policies, April 2020
    Utility regulators and other stakeholders need to improve their understanding of resilience and how distributed energy resources can facilitate recovery from disruptions and threats. This report addresses the role of state regulators in electricity system resilience, the relationship of distributed energy resources to resilience, and how states can implement policies to expand DER deployment to improve resilience.
  • Advancing Electric System Resilience with Distributed Energy Resources: Key Questions and Resources, April 2020
    As a companion piece to Advancing Electric System Resilience with Distributed Energy Resources: A Review of State Policies, this publication provides a foundation for state public utility commissions to frame how they review proposed utility investments that could offer resilience benefits and includes a list of relevant resources to improve regulators' ability to oversee resilience investments and obtain better outcomes for customers.
  • The Value of Resilience for Distributed Energy Resources: An Overview of Current Analytical Practices, April 2019
    Planning for long-duration power interruptions caused by high-impact, low-probability events requires new approaches to power system resilience above and beyond previous hardening efforts. This report examines both regulatory decision-making and non-regulatory cost-benefit analyses to determine if, and how, a value of energy resilience was calculated and applied to proposed investments. Four criteria were used to evaluate the methodologies, including the method’s ease of use, scope of outputs, geographic scalability, and power interruption duration analysis capability. Some of the valuation methodologies examined in the report may be useful in regulatory decision-making; however, none of the methods reviewed met all four criteria for regulator usefulness and usability, and no single method is capable of capturing all regulatory concerns regarding the resilience value of DERs.

  • Resilience for Regulators: Advancing Equitable Community Resilience Through Stakeholder Engagement Strategies, June 2023
    Energy justice has emerged as a central tenet to utility distribution system planning and federal funding eligibility in the last few years. Public utility commissions across the U.S. have begun the process of implementing energy equity requirements as dictated by state legislative statute or regulation. Both meeting federal requirements for funding eligibility and incorporating equity into distribution system planning broadly require robust stakeholder engagement from impacted energy justice communities. This webinar explored how public utility commissions are developing those equity-driven stakeholder engagement strategies to enhance distribution system resilience. Panelists discussed how state requirements around energy justice have evolved and how impacted communities can make a difference in building a grid that meets the needs of all customers regardless of their circumstances.

    As states, utilities, and other stakeholders seek to reduce the consequences of disruptions to the electric power sector from threats such as severe weather, cyber-attacks, and accidents, the need for regulators to consider how resilience can be properly internalized is coming into sharp focus. States, utilities, municipalities, and customers are increasingly taking steps to improve our communities’ resilience yet are doing so without the benefit of an established, clear and comprehensive set of planning considerations for grid resilience. Objectives for this workshop include: (1) to present and discuss work to date on overcoming critical barriers to development of a structured resilience framework; and (2) to explore commission experiences and needs related to important resilience topics.
