Overview
Susquehanna Junction Substation is an operational electrical substation in Pennsylvania, United States, operated by PPL. It operates at 230 kV, serving as a key node in the regional transmission grid.
Susquehanna Junction Substation is an operational electrical substation located in Pennsylvania, United States. Owned and operated by PPL, this facility is part of the high-voltage transmission network that supports the region's electricity distribution. The substation's voltage level of 230 kV places it in the medium-to-high voltage range, typical for sub-transmission and transmission applications. Operating under the regulatory oversight of the Federal Energy Regulatory Commission (FERC) and subject to North American Electric Reliability Corporation (NERC) reliability standards, the substation plays a role in maintaining grid stability. PPL, as the operator, adheres to these standards to ensure safe and reliable power delivery. The substation's equipment likely includes circuit breakers, transformers, and switchgear compliant with ISO/IEC 61850 for automation and communication. Environmentally, the substation's location in Pennsylvania's Susquehanna River region places it in an area with diverse ecological systems. The facility's operation is designed to minimize local environmental impact through proper insulation and maintenance practices. As part of the broader electrical infrastructure, it supports residential, commercial, and industrial customers, contributing to the reliability of the regional power grid.
Environmental context
The substation is situated in the Susquehanna River valley, an area characterized by mixed forest and agricultural land. Its operation involves electromagnetic fields and potential oil leakage from transformers, which are managed through standard containment and monitoring practices. The facility's urban-rural interface location requires careful consideration of land use and wildlife corridors, though specific environmental designations are not confirmed.
Frequently asked questions
