Contractors have started construction on a new PPL substation along SR209 between Nesquehoning and Lansford. Substations serve as a source of power supply for a community. The facilities tap into nearby electric transmission lines and convert the power to lower voltage for local distribution. They generally feature large circuit breakers, transformers and controls for power distribution. According the PPL's website, the facilities allow PPL to provide additional electric supply to a growing area and enhance reliability. The company operates about 400 electric substations currently across its service area.
