Electricity Grid Resilience: Climate Change is Expected to Have Far-Reaching Effects and DOE and FERC Should Take Actions, Report to Congressional Requesters [open pdf - 3MB]
From the Document: "According to the U.S. Global Change Research Program, changes in the earth's climate are under way and expected to increase, posing risks to the electricity grid that may affect the nation's economic and national security. Annual costs of weather-related power outages total billions of dollars and may increase with climate change, although resilience investments could help address potential effects, according to the research program. Private companies own most of the electricity grid, but the federal government plays a significant role in promoting grid resilience--the ability to adapt to changing conditions; withstand potentially disruptive events; and, if disrupted, to rapidly recover. DOE [Department of Energy], the lead agency for grid resilience efforts, conducts research and provides information and technical assistance to industry. FERC [Federal Energy Regulatory Commission] reviews mandatory grid reliability standards. GAO [Government Accountability Office] was asked to examine U.S. energy infrastructure resilience. This report describes: (1) potential climate change effects on the electricity grid; and (2) actions DOE and FERC have taken since 2014 to enhance electricity grid resilience to climate change effects, and additional actions these agencies could take. GAO reviewed reports and interviewed agency officials and 55 relevant stakeholders."
