The Lay Dam HPP is a gravity-dam run-of-river power plant on Coosa River, with 6 units of 30 MW where 4 units are foreseen to be upgraded in the near future. All units are of Kaplan type with fixed runner blades known as propeller-type Kaplan turbines. Commisioned in 1967 HPP is operated by Alabama Power Company.
Lay Dam HPP is our first American project, carried out in collaboration with Litostroj Hydro, which is responsible for the turbine modernization.
Our scope included machining in the flow section: the lower and upper rings, as well as boring holes for the installation of guide vane journal bearings.
