Front inscription
1,000 feet due north on a site now covered by Hartwell Reservoir, the Portman Shoals Power Plant, built by William C. Whitner, began in 1897 the transmission of high-voltage electricity over the longest lines then in use for that purpose in the United States. The success of this plant caused Anderson to be called "The Electric City."
