The Smithland hydroelectric facility, currently under development, will add 76 MW of new, renewable generation to the region. The plant is located near Smithland, Kentucky.
The Smithland project diverts water from the existing Corps Smithland Locks and Dam through bulb turbines to generate an average annual output of approximately 379 million kilowatt-hours (kWh). The site includes an intake approach channel, a reinforced concrete powerhouse and a tailrace channel. The powerhouse houses three horizontal bulb-type turbine and generating units with an estimated total rated capacity of 76 MW at a gross head of 22 feet. A 2-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 developed the Smithland plant on behalf of 79 participating AMP member communities as part of the Phase 1 Hydro Project. The Central Virginia Electric Cooperative is also participating in the project.
Excavation and cofferdam construction began in 2010 and powerhouse construction began in 2011. The plant reached full commercial operation in August 2017.
