The Pennsylvania Power & Light Co. is an energy utility and transmission distributer based in Allentown, Pennsylvania. Arising from a business merger, the company was founded on June 4, 1920, and soon after began providing energy to eastern and central Pennsylvania. Renamed PP&L Corporation circa 1995, the company continues to operate as an energy provider within northeastern Pennsylvania. The collection consists primarily of photographs that depict sites of various PP&L subsidiaries and those directly operated by the company. It is a resource that can be used for insight into PP&L's early operations and eastern and central Pennsylvania industrial development. Images within this collection range from 1920 to 1973. Researchers interested in electric power transmission and its development within the state of Pennsylvania would find this collection useful.

Pennsylvania Power & Light traces its origins to the various water and gas light companies that began operating in the eastern part of the state during the mid-nineteenth century. The records of the Pennsylvania Power & Light Company predecessor and subsidiary companies document the history of the gas and electric utility industry in eastern Pennsylvania in the years between 1853 and 1957. The collection includes both the administrative and operating records of more than 1100 companies that merged to form the PP&L system.
