  • Wolverine has served members for 60 years. The present-day Wolverine resulted from the merger of Wolverine Electric Cooperative and Northern Michigan Electric Cooperative in January 1983.

    Both Wolverine Electric Cooperative and Northern Michigan Electric Cooperative were chartered in 1948.

    Wolverine provides wholesale service to meet the power requirements of our six members, all serving customers at retail.


    Power plants

    Wolverine owns and operates six electric generating facilities primarily used for peaking capacity. These plants are capable of generating approximately 550 megawatts of electricity and are located in Belleville, Burnips, Gaylord, Hersey, Tower and Vestaburg.

    In addition, we are currently developing a base load power plant near Rogers City, Michigan. We have selected circulating fluidized bed (CFB) technology for the plant and plan to build two units at 300 megawatts each.

    Wind energy

    Wolverine is purchasing energy from the Harvest Wind Farm under a long-term agreement with John Deere Wind Energy, the project developer. The Harvest Wind Farm, the state’s first commercial-scale wind project, can produce enough electricity to serve 15,000 Michigan homes.

    We are also exploring the feasibility of a wind farm near Rogers City. Weather data is currently being collected at the proposed site.


    Wolverine owns and operates an extensive electric transmission network in the western and northern portions of Michigan’s Lower Peninsula. Wolverine has nearly 1,200 miles of 69 kV and 138 KV looped transmission lines and associated facilities. Wolverine and other companies use these transmission facilities to integrate power supply resources with customer loads.

    Beginning January 1, 2006, the commencement date of the Michigan Joint Zone, Wolverine transferred operational control of its transmission facilities to the Midwest ISO.

    Wolverine also owns and operates approximately 390 miles of radial transmission facilities that provide transmission service to distribution substations connected to our network. These facilities serve as the interface between Wolverine and our transmission members.

    Wolverine maintains a state-of-the-art Energy Control Center at our Cadillac headquarters for the real-time monitoring of all transmission and generation functions. Our Energy Control Center is staffed 24 hours a day, seven days a week.
