Overview
Mifflintown Substation is an operational electrical substation in Pennsylvania, United States, owned and operated by PPL. It operates at 69 kV, supporting regional grid stability.
Mifflintown Substation is an electrical substation located in Pennsylvania, United States, owned and operated by PPL. The facility is operational and serves as a key node in the local power distribution network, stepping down transmission-level voltages for regional consumption. The substation operates at a voltage of 69 kV, which is typical for sub-transmission and distribution substations in the United States. As part of PPL's infrastructure, it adheres to North American Electric Reliability Corporation (NERC) reliability standards and is subject to Federal Energy Regulatory Commission (FERC) oversight for grid reliability and market operations. This facility plays a critical role in ensuring reliable electricity supply to the surrounding communities and industrial users. Its location in central Pennsylvania places it within a region with diverse energy needs, supporting both residential and commercial loads. The substation's operational status contributes to the resilience of the regional grid.
Environmental context
The substation is situated in a rural area of central Pennsylvania, where the surrounding landscape includes agricultural fields and forests. Electrical infrastructure in such settings typically has minimal direct environmental impact, though it supports the broader grid that powers local communities and industries. The 69 kV voltage level indicates a medium-scale facility, with standard environmental considerations including electromagnetic field management and vegetation control around rights-of-way.
