After the hurricane: Validating a resilience assessment methodology

摘要: Abstract With increasing utility grid outages in the United States, there is growing interest assessing risk and developing mitigation strategies to reduce impact of outages. Working with U.S. Air Force, Department Energy's National Renewable Energy Laboratory (NREL) developed a replicable energy resilience assessment methodology investment decision tool to: (1) identify score hazards vulnerabilities at site level; (2) analyze risks infrastructure; (3) prioritize investments. This work improves on existing methodologies tools by combining bottom-up, all-hazards top-down geographic information system mapping capabilities provide an innovative, dynamic for identifying prioritizing actionable solutions. process combines probabilistic forecasting iterative approach continuously updating reassessing address temporal dynamism. Relationships among systems are modeled visualized estimate effectiveness actions across multiple interdependent inform financial priorities through cost-difficulty-impact trade-offs. The validated case study Tyndall Force Base (AFB) Florida, which experienced Category 5 hurricane 2018. identified pre-hurricane compared post-hurricane, realized impacts. effectively identifies increase resilience, but can be enhanced though greater consideration interdependencies between related like transportation, communication, food/water systems, recovery base.
