Johnsville Substation - Operational 69 kV Electrical Substation in the United States

Johnsville Substation is an operational electrical substation located in the United States, with coordinates 45.200943, -93.235649. The facility operates at a voltage of 69 kV, which classifies it as a medium-voltage substation typically used for subtransmission or distribution within the electrical grid. As a substation in the United States, Johnsville Substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) reliability standards and Federal Energy Regulatory Commission (FERC) oversight for transmission-level assets. The 69 kV voltage level is common for distribution substations that step down power from higher transmission voltages to serve local industrial, commercial, and residential loads. The substation's location in the Midwest region places it within a grid that supports a mix of urban and rural loads. Its operational status ensures continued contribution to local grid reliability and power delivery. The facility's role in the electrical infrastructure network is essential for maintaining stable electricity supply to the surrounding area.

The substation's location in the Midwest United States places it in a region with diverse environmental conditions, including cold winters and warm summers. The 69 kV voltage level indicates a distribution-scale facility, which typically has a localized environmental footprint. Substations of this type are often situated in areas that balance grid connectivity with land use considerations, and their operation is subject to environmental regulations regarding electromagnetic fields, noise, and stormwater management.
