TVA has completed repairs to its power transmission system, which was damaged during the March 2 storms and tornadoes.
Tennessee Valley Authority spokesman Mike Bradley said the last three transmission lines were returned to service Thursday.
At one point 17 lines were out of service after high winds tore down towers and transmission lines, TVA has said.
Sequoyah Unit 2, which had been lowered to 70 percent power when so many transmission lines were down, was returned to 100 percent power Sunday, Bradley said.
