Overview
Williamsport Substation is an operational electrical substation in Pennsylvania, United States, owned and operated by PPL. It operates at 69 kV, serving the local grid.
Williamsport Substation is an operational electrical substation located in Pennsylvania, United States. Owned and operated by PPL, this facility plays a key role in the regional power distribution network, stepping down transmission voltages for local delivery. The substation operates at a voltage of 69 kV, which is typical for sub-transmission and distribution-level infrastructure in the United States. As part of the PJM Interconnection grid, it adheres to NERC reliability standards and FERC regulations, ensuring stable and secure electricity supply to the surrounding area. Located in north-central Pennsylvania, the substation supports the local community and industrial base. Its operational status and connection to the broader PJM network contribute to grid resilience and energy reliability for the region.
Environmental context
The substation is situated in a mixed urban and rural area of Pennsylvania, where electrical infrastructure supports residential, commercial, and industrial loads. The 69 kV voltage level indicates a distribution role, with lower environmental footprint compared to high-voltage transmission lines. Local grid operations are subject to environmental regulations under the Clean Air Act and state-level siting requirements.
