Holcombe Substation - 69 kV Electrical Substation in the United States

Holcombe Substation is an operational electrical substation located in the United States, with coordinates 45.224117, -91.110661. The facility operates at a voltage of 69 kV, which is typical for sub-transmission or distribution-level infrastructure, serving to step down power for local distribution networks. As a substation in the U.S., Holcombe Substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) reliability standards and is subject to Federal Energy Regulatory Commission (FERC) oversight for transmission-level assets. The 69 kV voltage level places it in the medium-voltage category, often used for regional power distribution to industrial or large commercial customers. The substation's location in a rural area of Wisconsin suggests it supports agricultural or small community power needs. The facility's role in the local electrical infrastructure is critical for maintaining stable power supply to surrounding areas.

The substation is situated in a rural area of Wisconsin, characterized by agricultural land and scattered woodlands. The local environment is typical of the Upper Midwest, with cold winters and moderate summers. Electrical infrastructure in such settings must withstand seasonal temperature extremes and potential ice storms, which can affect overhead lines and equipment. The 69 kV voltage level is suitable for regional distribution, minimizing environmental footprint while supporting local energy needs.
