Electric Operations Statistics

Consumers Energy delivers electricity to nearly 1.8 million homes and business throughout Michigan's Lower Peninsula.

To meet our customers' needs, we generate power from four fossil fuel generating plants, 13 hydroelectric plants, a pumped storage generating plant, and several combustion-turbine plants that generate electricity during peak demand periods. We also purchase power from a number of sources, including a nuclear plant and the gas-fired Midland Cogeneration Venture.
