Tour of Meldahl Hydroelectric Plant

Hosts: City of Hamilton, Ohio, and American Municipal Power
Maximum Capacity: 50 people (Sold Out!)

Tour participants will experience the 105-MW run-of-the-river plant up close.

Named after Captain Anthony Meldahl, a renowned Ohio River riverboat captain in the 1800s, the Meldahl Hydroelectric Plant is located in Foster, Kentucky, an hour southeast of Cincinnati, at a U.S. Army Corps of Engineers’ lock and dam.

The facility, which reached full commercial operation in 2016, is the largest hydroelectric power plant on the Ohio River and has an annual output of 523.2 million kilowatt-hours, with the highest annual output occurring in 2021 with 639.4 million kilowatt-hours generated.

The site includes an intake approach channel, a reinforced concrete powerhouse, and a tailrace channel. The powerhouse contains three horizontal bulb-type turbine-generating units with a total rated capacity of 105 MW.

The tour features a look at the powerhouse, which sports a crane spanning 190 feet that can pick up 175 tons – the equivalent of a Boeing 747 jet.

The powerhouse is designed to be overtopped during flood events by as much as 25 feet of water.
