Natural disasters, such as cyclones, earthquakes, hurricanes, wildfires, and severe storms—and the power outages resulting from these disasters—have affected millions of customers and cost billions of dollars. The growing severity of wildfires and extreme weather events in recent years has been a principal contributor to an increase in the frequency and duration of power outages in the U.S. Federal agencies, such as DOE and the Federal Emergency Management Agency, play a significant role in disaster response, recovery, and resilience.
This report (1) identifies lessons learned from federal, state, and other entities’ responses to selected disasters that affected the electricity grid from 2017 to 2021; and (2) examines federal agency actions to address those lessons learned. GAO selected a nongeneralizable sample of 15 of 35 disasters that affected the grid from 2017 to 2021. The 15 selected were among the most severe events across a range of types, locations, and years. GAO also examined agency and industry responses; reviewed relevant reports, policies, and documents; and interviewed federal, state, and local officials, as well as selected industry stakeholders.
