Pennsylvania Water & Power Company photographs

 Collection
Accession: 2015-293
Abstract:

Pennsylvania Water & Power Company was established to store, transport, and generate water power for both commercial and manufacturing purposes. The Holtwood facility outside of Lancaster, Pennsylvania was the first power plant to have both a hydroelectric generator and a coal power generator. The company was originally called McCall’s Ferry Power Co. and founded in 1905. This small collection consists of photographs that depict the progress of several construction projects at the Holtwood and Safe Harbor plants. Most of these images date from 1951 to 1954, well after the original construction of both sites.

Dates: circa 1916-1992; Majority of material found within 1931-1954
