2017 Hurricane Season: Federal Support for Electricity Grid Restoration in the U.S. Virgin Islands and Puerto Rico
Abstract
In 2017, Hurricanes Irma and Maria damaged much of the electricity grids' transmission and distribution systems in USVI and Puerto Rico. The hurricanes left most of USVI's 106,405 people and all of Puerto Rico's 3.3 million without power and resulted in the longest blackout in U.S. history. Under the National Response Framework, electric utilities are responsible for repairing infrastructure and restoring service. They often use mutual assistance - voluntary partnerships with other electric utilities - to bring in additional resources to help restore electricity. Federal agencies provide financial assistance; help coordinate the federal response; and in severe emergencies, provide logistical support, such as assisting in damage assessments and location and transportation of repair crews and equipment. GAO was asked to review the federal response to the 2017 hurricanes. This report provides information on federal support for restoring the electricity grids in Puerto Rico and USVI and factors affecting this support. GAO has ongoing work examining federal support to improve grid resilience in Puerto Rico. GAO reviewed agency documents and funding data through July 20, 2018, the most recent data available; interviewed officials from FEMA, DOE, and USACE; and conducted site visits to Puerto Rico and USVI.
