Overview
Millersville Substation is an operational electrical substation in Pennsylvania, United States, owned and operated by PPL. It operates at 69 kV, serving as a key node in the regional power grid.
Millersville Substation is an operational electrical substation located in Pennsylvania, United States. Owned and operated by PPL, this facility plays a critical role in the regional transmission and distribution network, stepping down high-voltage electricity for local distribution. The substation operates at a voltage level of 69 kV, which is typical for sub-transmission and distribution substations in the United States. As part of PPL's infrastructure, it is subject to NERC reliability standards and FERC regulation, ensuring grid stability and compliance with mandatory reliability requirements. The facility likely includes switchgear, transformers, and protection systems conforming to industry standards such as IEEE C37. Millersville Substation serves the electrical needs of the surrounding community, contributing to the reliability of power supply in the region. Its location in Pennsylvania places it within the PJM Interconnection, one of the largest regional transmission organizations in the U.S., which coordinates the movement of wholesale electricity across multiple states.
Environmental context
The substation is situated in a suburban area of Pennsylvania, where land use is a mix of residential and agricultural. Electrical infrastructure like this can have localized environmental impacts, including electromagnetic fields and potential oil leaks from transformers. However, modern substations are designed with containment measures and are subject to environmental regulations under the Clean Water Act and state-level oversight.
Frequently asked questions
