Two more Portman Shoals insulators. These have the Imperial markings on the side unlike the other one.

In 1897, engineer William Whitner's Portman Shoals Hydroelectric Plant started producing electricity, transmitted to Anderson, SC. The transmission line was 10 miles and provided electricity to the Anderson, SC, the Anderson Traction Company and the Anderson Cotton Mills. Today the power plant is under Lake Hartwell, which flooded the area in the 1950s for a larger hydroelectric dam. Portman Shoals was the longest transmission line in the Southern US at the time. Anderson, SC is known as "The Electric City" for the electric street lights that were along main street in the late 1890s. [id=340212432]
