WASHINGTON (AP) — In southwestern Pennsylvania, eight locks and dams that for decades helped barges move goods along the Allegheny, Monongahela and Ohio rivers will in a few years also generate enough power for 75,000 homes.
Rye Development, a Boston-based hydropower company, is retrofitting the dams with turbines to generate electricity and says the upgraded structures will limit damage to the rivers’ water quality and fish.
