Notes
Survey number HAER WV-61
Unprocessed field note material exists for this structure (N748).
Building/structure dates: 1889 initial construction
Building/structure dates: 1925 subsequent work
Significance: The Potomac Power Plant was an innovative small hydroelectric facility that operated from 1899 to 1991, originally as part of a wood pulp mill (built 1888), and solely as a power house after a fire in 1925. Significant extant equipment/machinery in the plant includes a c.1905 Dayton Globe water turbine, and a 1925 Woodward water turbine governor. The building is also symbolic of industry in Harpers Ferry, as it occupies the site (and possibly the partial foundations) of Harpers Ferry National Armory buildings dating to 1834 and 1853, and contains reused structural materials from various Armory buildings as well as from an 1848 Harpers Ferry cotton mill (later a flour mill).
