Hydro-electric Power Plant

Across the Potomac River at the south end of Dam #4 is a power plant built by Martinsburg Power Company in 1909. This plant is still operated by Alleghany Power and still uses African sisal rope in the rope drives and South American guaiacum tree wood bearings. This is the only plant in the country to still have these older features.
