Meldahl Hydro Plant

View all


The Meldahl Hydroelectric Project is a 105 MW run-of-the-river hydroelectric power plant providing renewable generation to the region. The facility is the largest hydroelectric power plant on the Ohio River.

The Meldahl Project diverts water from the existing U.S. Army Corps of Engineers’ Meldahl Locks and Dam through bulb turbines anticipated to generate an average annual output of approximately 558 million kilowatt-hours (kWh). The site includes an intake approach channel, a reinforced concrete powerhouse and a tailrace channel. The powerhouse contains three horizontal bulb-type turbine and generating units with a total rated capacity of 105 MW.

The Captain Anthony Meldahl Locks and Dam are located near Maysville, Kentucky, approximately an hour southeast of Cincinnati. The Meldahl hydroelectric plant is on the Kentucky side of the Ohio River, on the opposite shore of the locks.

The plant reached full commercial operation in April 2016.
