From the Abstract: "The U.S. electricity system is a critical infrastructure that supports human well-being, economic growth, and national security. Comprised of four core components generation, transmission, distribution, and end use, and, increasingly, dependent on supporting infrastructure such as communication and fuel supply the electricity system has multiple vulnerabilities to both natural and human risks. These risks range from the routine and predictable, such as weather events that disrupt transmission or distribution, to high impact, low frequency risks such as catastrophic hurricanes. In addition to such well-defined, discrete risks, electricity systems can also be challenged by complex risks associated with multiple, interacting threats, and/or indirect effects. [...] Future efforts toward building resilience should focus on risk assessment and planning for multiple and emerging contingencies, particularly for potentially catastrophic threats. Continuing to invest in new generation technologies and grid modernization while enhancing the capacity for launching coordinated responses across multiple actors will generate significant benefits in terms of maintaining reliability. Such investments will also help enable the system to keep pace with the rapidly changing nature of the U.S. energy sector and emerging threats."
