Nashville District
Published Jan. 9, 2024


The Nashville District Hydropower Program began under the Flood Control Act of 1938, which authorized minimum provisions for hydropower at flood control projects.  The first power plant constructed in the Cumberland River Basin was Dale Hollow, with the first unit coming online in 1948.  Over the next thirty years eight other power plants were constructed, ending with Laurel which was completed in 1977.  In all, the Nashville District operates and maintains ten dam projects in the Cumberland River Basin, nine of which are multi-purpose projects with hydroelectric power plants, and remotely monitors (with the ability to operate) one power plant at the Sault Ste. Marie project in Michigan.  The nine power plants in the Cumberland River Basin have a total of 28 generating units with a current aggregate generating capacity of more than 927 megawatts (MW).  The Nashville District provides management, operation and maintenance of all electrical, mechanical, and structural features at these projects, including the power plants, dams, spillways and high voltage switchyards.

The Southeastern Power Administration (SEPA) markets the power from these plants through negotiated power sales and operating agreements with Tennessee Valley Authority (TVA) and regional utility companies.  The power produced at these projects is delivered to 25 preference entities that serve 209 preference customers in Alabama, Georgia, Illinois, Kentucky, Mississippi, North Carolina, Tennessee and Virginia. 

On average, the Nashville District power plants produce over 3.2 billion kilowatt-hours (kWh) each year.  Based on an average annual household consumption of 10,715 kWh as provided by the U.S. Energy Information Administration, that is enough energy to support 304,000 homes annually.

Test Lab

  • Performs services to the hydropower community

  • Test power plant insulation systems in the generators, transformers, air circuit breakers, and oil circuit breakers in the districts nine power plants

  • Maintain the remote control equipment for four remote power plants and three master plants including the communication paths

  • Compile the revenue data from the nine plants daily and send the information to SEPA (South Eastern Power Administration)

  • Investigate all electrical faults, trouble shoot problems as needed

  • Provide some design work for equipment replacement items

  • Test protection relays for all plants and line relays

  • Made up of three engineers, four technicians, one coop and one field office assistant
