Cocalico Substation - 69 kV Operational Substation in Pennsylvania, United States

Cocalico Substation is an operational electrical substation located in Pennsylvania, United States. Owned and operated by PPL, it plays a role in the regional transmission and distribution network, stepping down voltage for local distribution. The substation's 69 kV voltage level places it in the medium-voltage range, typical for sub-transmission and distribution substations in the United States. As part of the U.S. electrical infrastructure, Cocalico Substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These bodies enforce reliability standards and oversee interstate electricity transmission. The substation likely employs standard switchgear and protection systems compliant with industry practices, including potential use of IEC 61850 for automation and communication. Cocalico Substation contributes to grid stability and power delivery in its area. Its location in Pennsylvania, a state with a mix of urban and rural loads, means it supports both residential and industrial customers. The substation's operational status ensures continued reliability of the local grid, and its integration with PPL's network underscores its importance in maintaining consistent electricity supply.

The substation is situated in a region with a temperate climate, where seasonal weather variations can impact grid operations. Its rural setting may reduce some environmental constraints compared to urban substations, but it still requires compliance with local environmental regulations regarding electromagnetic fields and stormwater management. The 69 kV voltage level indicates moderate electromagnetic field emissions, which are managed through standard siting and shielding practices.
