The electric system is comprised of generating plants, transmission lines, and distribution facilities. The MPSC regulates generation and distribution functions in the state of Michigan for eight privately owned electric utilities (investor-owned). The MPSC works to ensure they have adequate supply of electric energy to serve Michigan’s homes and businesses in each service territory when demand is highest and approves the rates and conditions of service, including metering and billing, to residential, commercial, and industrial customers. Michigan’s transmission system is regulated by FERC.
All electric cooperatives in Michigan are member-regulated. The MPSC’s oversight of member-regulated cooperatives is limited to code of conduct, electric choice rates, service territory designation, and service quality and safety standards.
Municipally owned electric utilities are not subject to MPSC regulation.
