Grid Resilience Plans: State Requirements, Utility Practices, and Utility Plan Template

Summary

This Lawrence Berkeley National Laboratory report provides a standard template for grid resilience plans, addressing the increasing frequency and severity of extreme weather events that pose unprecedented challenges to electricity grids. As of June 2024, 14 U.S. states and one city require such plans, with 30 regulated utilities having filed plans covering over 47 million customers (39% of the U.S. population) between May 2022 and June 2024. The template draws from best practices in these filings, including varied planning horizons (e.g., 10+ years generally, 20-50 years for climate assessments, 3 years for wildfire plans) and a focus on vulnerability assessments and cost-effective solutions. Key examples of specific investments include Tampa Electric's proposed $1.59 billion for storm protection over 10 years and Eversource's $206 million restoration cost for Tropical Storm Isaias, highlighting the financial impact of grid disruptions.
