Corwith Substation - 138 kV Electrical Substation in Michigan, United States

Corwith Substation is an operational electrical substation located in Michigan, United States. Owned and operated by Wolverine Power Supply Cooperative, the facility plays a role in the regional transmission network, stepping down high-voltage electricity for distribution to local communities. The substation operates at a voltage of 138 kV, a common transmission-level voltage in the United States. As part of the North American power grid, it is subject to reliability standards set by the North American Electric Reliability Corporation (NERC) and regulated by the Federal Energy Regulatory Commission (FERC). The facility's equipment likely includes circuit breakers, transformers, and switchgear compliant with IEEE standards. As a transmission substation, Corwith Substation is critical for maintaining grid stability and ensuring reliable power supply to the surrounding area. Its location in rural Michigan supports the electrical infrastructure needs of the region, contributing to the overall resilience of the local power system.

The substation is situated in a rural area of Michigan, where the surrounding landscape includes forests and agricultural land. Electrical infrastructure in such settings must consider potential impacts on local wildlife and habitats, particularly during construction and maintenance. The 138 kV voltage level indicates moderate environmental footprint, with typical mitigation measures including oil containment for transformers and vegetation management to prevent outages.
