In an effort to better understand what actions the energy industry has taken in response to the 2005 and 2008 hurricane seasons, the U.S. Department of Energy, Office of Electricity Delivery and Energy Reliability (DOE/OE) conducted research to identify specific industry efforts related to storm hardening and resiliency. This book focuses on the measures that refiners, petroleum product pipeline operators, and electric utilities in the Gulf Coast have taken to harden their assets and make energy supply to the Southeast more resilient. Discussions with the public utility commissions identified additional sources of information on storm hardening in extensive dockets, and focused on the segments of the energy industry that contribute most to the delivery of gasoline and diesel to the Southeast, United States.
