Overview
Hummels Wharf Substation is an operational electrical substation in Pennsylvania, United States, owned and operated by PPL. It operates at 69 kV, serving the local grid.
Hummels Wharf Substation is an electrical substation located in Pennsylvania, United States. Owned and operated by PPL, the facility is currently operational and plays a role in the regional power distribution network. The substation operates at a voltage of 69 kV, which is typical for sub-transmission and distribution-level infrastructure. As part of the U.S. electrical grid, this substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These bodies establish reliability standards and oversee the interstate transmission of electricity. The 69 kV voltage level places this facility in the medium-voltage category, commonly used to distribute power from transmission systems to local distribution networks. The substation's location in Pennsylvania, a state with a diverse energy mix including nuclear, natural gas, and renewables, underscores its role in maintaining grid stability. By stepping down voltage for local distribution, it supports residential, commercial, and industrial customers in the surrounding area. Its operational status ensures continued reliability of electricity supply to the community.
Environmental context
The substation is situated in a rural area of Pennsylvania, where the surrounding landscape includes agricultural land and small communities. The 69 kV voltage level indicates it serves as a distribution substation, which typically has a smaller environmental footprint compared to high-voltage transmission facilities. The site's design likely includes measures to minimize electromagnetic field exposure and manage stormwater runoff, in line with local environmental regulations.
