Stoney Corners Substation - 69 kV Electrical Substation in Michigan, United States

Stoney Corners Substation is an operational electrical substation located in Michigan, United States. Owned and operated by Wolverine Power Supply Cooperative, it plays a role in the distribution and transmission of electricity within the region. The substation operates at a voltage of 69 kV, which is typical for sub-transmission or distribution-level infrastructure in the United States. As part of the U.S. electrical grid, this facility operates under the regulatory framework established by the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These standards ensure reliability and security of the bulk power system. The substation likely includes switchgear, transformers, and protection systems compliant with industry standards such as IEEE and IEC. The substation's location in rural Michigan supports the local power distribution network, serving residential, agricultural, and possibly small industrial customers. Its operation contributes to grid stability and reliability in the area, particularly during peak demand periods or extreme weather events common in the Midwest.

The substation is situated in a rural area of Michigan, characterized by mixed forest and agricultural land. Its operation involves electromagnetic fields and potential oil containment from transformers, which are managed under environmental regulations. The site's distance from urban centers reduces direct exposure to sensitive populations, but proximity to natural habitats requires adherence to local environmental protection standards.
