NASHVILLE (AP) - The Tennessee Valley Authority says an unusually wet summer has translated into lower electric bills for customers.
John McCormick, Tennessee Valley Authority's vice president for river operations, said in a statement that the rain kept the utility's hydroelectric dams, which provide the cheapest source of energy, working overdrive.
Scott Brooks, a Nashville-based TVA spokesman, told The Tennessean that the extra hydro power has allowed TVA to purchase less energy from more expensive sources, a pattern is expected to continue this month.
The rainfall has led to a record-setting year for TVA's 29 hydroelectric dams, which produced more energy in 2013 than at any other time in the past eight decades.
TVA serves 9 million people in parts of seven southeastern states.
