The Smithland hydroelectric facility, currently under development, will add 72 MW of new, renewable generation to the region. The plant is located near Smithland, Kentucky.

The Smithland project will divert water from the existing Corps Smithland Locks and Dam through bulb turbines to generate an average gross annual output of approximately 379 million kilowatt-hours (kWh). The site will include an intake approach channel, a reinforced concrete powerhouse and a tailrace channel. The powerhouse will house three horizontal FERC rated 24-MW bulb-type turbine and generating units with an estimated total rated capacity of 72 MW at a gross head of 22 feet. A 2.5-mile-long 161 kV transmission line interconnection is planned to connect to MISO.

Smithland is located approximately 62 river miles upstream of the confluence of the Ohio and Mississippi rivers, in Livingston County, Ky.

AMP is developing the Smithland plant on behalf of 79 participating AMP member communities. The Central Virginia Electric Cooperative is also participating in the project.

The Smithland project, as of July 19, 2013, employed more than 200 workers and more than 400 construction workers are expected at the peak of construction. Once online, it will provide up to nine permanent operating positions. AMP signed a contract in June 2008 with York, Pennsylvania-based Voith Hydro for the manufacture of turbines and generators. CJ Mahan Construction completed the excavation and cofferdam construction in 2012 and powerhouse construction began in April 2012 with CJ Mahan as contractor.

  • Location: Kentucky side of the Ohio River, near Smithland, Kentucky (about 3 ½ hours southwest of Louisville, Ky.)
  • Estimated capacity: 72 MW
  • Estimated construction jobs: Over 400 at peak of construction
  • Estimated permanent jobs: 7-9
  • Formal groundbreaking: Held September 1, 2010, featuring Kentucky Governor Steve Beshear and Congressman Ed Whitfield (KY-1), and state and local officials
