Enhancing the Resilience of the Nation's Electric Power Transmission and Distribution (T&D) System

Completed

Electricity is essential for our day-to-day lives. It powers our homes, commercial and industrial activities, and critical social services such as hospitals and emergency responders. Nearly all other vital infrastructures such as telecommunications, natural gas delivery, and transportation are dependent on continually available electricity. However, electricity systems in the U.S. and other countries are vulnerable to diverse and evolving threats that can cause large-area outages that last for days, weeks, or longer. This report identifies technologies, policies, and organizational strategies to increase the resilience of the nation's electric system in the face of large outages.

Description

An ad hoc National Research Council (NRC) committee will address technical, policy and institutional factors that might affect how modern technology can be implemented in the evolution of electric transmission and distribution (T&D) in the United States and recommend strategies for how the nation can move to a more reliable and resilient T&D system. The committee will consider how existing and emerging technological options, including greater reliance on distributed power generation, could impact the reliability, robustness and the ability to recover from disruptions to the electrical T&D system, or systems. The study will identify barriers to implementing technology for improving T&D reliability, including priorities where necessary, for research, development and demonstration (RD&D), and strategies and actions that could lead to a more reliable and resilient T&D system. As part of this study the committee may:

(1) review recent studies and analysis of the current and projected status of the nation’s electric T&D system, including any that identify significant technological concerns over vulnerability, reliability and resilience;
(2)
assess factors affecting future requirements and trends for the nation's T&D infrastructure, including such issues as the need for new capacity, replacement needs, siting issues, vulnerability to external threats and the need for security, whether physical or cyber, the alignment of costs and benefits, the effects of interconnectedness among regional networks, and others identified by the committee;
(3)
evaluate the role existing and emerging technological options (including renewable and distributed generation technologies), can play in creating or addressing concerns identified by the committee and that can lead to enhanced reliability and resilience;
(4) review federal, state, industry, and academic R&D programs, as well as any demonstration and/or deployment efforts, focused on technologies for the T&D system that are aimed at improving its capacity, reliability, resilience, flexibility and any other attributes aimed at enhancing the robustness of the nation’s electric power T&D system;
(5)
identify non-technological barriers (including those related to regulatory and ownership issues) to the implementation of new and/or expanded technology to improve the stability, reliability, and resilience of electric T&D; and
(6)
suggest strategies, priorities, and actions for implementation of the identified technologies for the T&D system, which could include RD&D, policies, incentives, standards, and others the committee finds are necessary.
The committee will write a report documenting its findings and recommendations. The report will be issued by the National Academies approximately 18 months from the time funds are received to initiate the study.
