Remembering the Terrible Tornadoes of 2011

Wednesday, April 27, 2011, will go down in history as one of the worst tornado outbreaks in a single day in American history. Here's what happened that fateful day, and how TVA acted to meet the challenge of repairing the damage and putting the lights back on.

Three severe storm fronts tracked across the Tennessee Valley throughout the day on April 27, 2011, resulting in multiple tornadoes and challenges across the TVA system—including 350 damaged structures and 100 lines out of service; 12 generating facilities knocked out of service; a nuclear plant (Browns Ferry) tripped offline; and 5,000 MW of power lost in a matter of hours.

This is the story of what happened that terrible day, and how with teamwork, courage and a willingness to go above and beyond the call of duty, TVA employees responded to restore the system and get power back on to 850,000 consumers, restoring power to 124 of 128 interrupted delivery points within the space of only a week.
