Onaway Substation is an operational electrical substation located in Onaway, Michigan, United States. Owned and operated by Wolverine Power Supply Cooperative, it serves as a key node in the regional electrical infrastructure, stepping down transmission voltages for local distribution. The substation operates at a voltage of 69 kV, which is typical for sub-transmission or distribution-level facilities in the United States. As part of the Wolverine Power Supply Cooperative network, it likely adheres to NERC reliability standards and FERC regulations, ensuring stable and secure grid operations. The facility's age and specific equipment are not detailed, but substations of this voltage class commonly employ air-insulated or gas-insulated switchgear. Located in a rural area of Michigan, Onaway Substation supports the electrical needs of the surrounding community, including residential, agricultural, and small commercial customers. Its role in the cooperative's distribution system underscores its importance for local grid stability and reliability, particularly in a region with seasonal weather variations that can impact power infrastructure.

The substation is situated in a rural area of Michigan, characterized by forests and agricultural land. Its operation involves minimal direct environmental impact, though electromagnetic fields and potential oil leaks from transformers are standard considerations. The 69 kV voltage level indicates a moderate scale, with typical environmental management practices including spill containment and vegetation control around the site.
