Butternut Substation - 34.5 kV Electrical Substation in Wisconsin, United States

Butternut Substation is an operational electrical substation located in the United States, owned and operated by Dairyland Power Cooperative. The facility operates at a voltage of 34.5 kV, classifying it as a medium-voltage substation within the electrical infrastructure network. As a substation in the United States, Butternut Substation operates under the regulatory framework established by the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These standards ensure grid reliability and security for transmission and distribution assets. The 34.5 kV voltage level indicates this substation likely serves a distribution function, stepping down power for local industrial or residential use. The substation plays a role in maintaining grid stability in its region, contributing to the reliable delivery of electricity to end-users. Dairyland Power Cooperative, a generation and transmission cooperative, operates this facility as part of its broader network serving member cooperatives in the upper Midwest.

The substation is located in a rural area of northern Wisconsin, near the town of Butternut. The surrounding environment includes forested lands and wetlands, which are typical of the region. Electrical infrastructure in such areas must consider wildlife corridors and vegetation management to prevent outages. The 34.5 kV voltage level suggests a moderate environmental footprint, with standard mitigation measures for electromagnetic fields and stormwater runoff.
