Average Fuel Mix Comparisons

Beginning January 1, 2002, the Customer Choice and Electric Reliability Act gave all consumers in Michigan the option to choose the company that provides their electric supply. When choosing a supplier, it is important to know the sources of generation different companies may have. Included here is information regarding Public Service's fuel mix and emissions compared to other regions.

The environmental characteristics of your electricity as reported to the Michigan Public Service Commission pursuant to Public Act 141 of 2000 are as follows:
