The postulated mechanisms are geomagnetic storms, electromagnetic pulse attacks (EMP) via a high altitude nuclear detonation, cyberattacks, and kinetic attacks. The likelihood of such events and the consequences to the American public of a protracted electric power failure are reviewed.
In five of the past 11 years, parts of the U.S. electrical grid have been hit by blackouts, shut-offs or close calls during cold weather. Experts say one reason is a recurring shortage of natural gas.
During a power outage, there is a disruption in the supply of electricity, resulting in a loss of power to homes, businesses, and other facilities. Power outages can occur for various reasons, including severe weather conditions (e.g. storms, hurricanes, or blizzards), earthquakes, equipment failure, grid overload, or planned maintenance.
The blackout was due to a cascading failure of the power grid started by a transformer failure. Some lines of the Moscow Metro lost power, stranding people in trains, 10 weeks fully power restored. August 29—United States—Hurricane Katrina caused widespread power outages throughout Louisiana, Mississippi, Alabama, Florida, Kentucky, and ...
The Electric Reliability Council of Texas, the power grid manager for most of the state, has in the past called for power conservation when grid conditions are tight to help avoid a grid blackout ...
Entergy says it's committed to storm-hardening and clean power. Critics say it works against those goals. How a Southern utility guards its monopoly — and endangers the power grid, critics say
While some homes have spent up to eight hours a day this year without electricity as the grid has grown more unstable, the current power failure is considered Cuba’s worst in years. Officials said that 1.64 gigawatts went offline during peak hours, about half the total demand at the time.
Data showed that failure to winterize traditional power sources, principally natural gas infrastructure but also to a lesser extent wind turbines, had caused the grid failure, [15] [16] with a drop in power production from natural gas more than five times greater than that from wind turbines.
