Catoctin Substation - 138 kV Electrical Substation in the United States

Catoctin Substation is an operational electrical substation located in the United States, with coordinates 39.613426, -77.409838. The facility operates at a voltage of 138 kV, placing it in the medium-to-high voltage range typical for sub-transmission and distribution substations. As part of the U.S. electrical infrastructure, it supports the reliable delivery of electricity to local communities and industries. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and is subject to Federal Energy Regulatory Commission (FERC) oversight for reliability standards. The 138 kV voltage level is commonly used for regional power distribution, connecting higher-voltage transmission lines to lower-voltage distribution networks. The facility's location in a rural or suburban area of Maryland suggests it serves a mix of residential and commercial loads. Catoctin Substation contributes to the resilience of the local power grid by providing voltage regulation and switching capabilities. Its operational status ensures continued service to the surrounding area, supporting economic activity and community needs. The substation's integration into the broader U.S. grid highlights its role in maintaining system reliability and power quality.

The substation is situated in a region with a temperate climate, where seasonal weather patterns can impact grid operations. The 138 kV voltage level indicates moderate environmental footprint, with typical considerations for electromagnetic fields and land use. The facility's location in a non-urban area reduces direct exposure to sensitive ecosystems, though standard mitigation measures for wildlife and vegetation management are likely in place.
