Georgia Power Upgrades Transmission Lines

Georgia Power, a subsidiary of Southern Company, chose 3M’s ACCR overhead conductor to double transmission capacity on a set of lines that cross wetlands near Savannah, Ga. The upgrade is on a 16.7-mile line linking the Kraft generating plant in Savannah with the McIntosh plant north of the city. The project resolves potential capacity issues by approximately doubling the 230-kV double circuits’ line capacity, replacing a steel core conductor with a 3M conductor light enough to be accommodated mostly by existing infrastructure.
