Michigan regulators have approved adding new fees to monthly bills for customers of 40 municipal utilities in the state.
The surcharges will help the utilities meet energy-efficiency requirements under a 2008 state law.
The "energy optimization" fees range from a low of 13 cents a month in Marshall to a high of $1.26 per month in Coldwater.
Some city-owned utilities also are allowed to charge up to $3 a month to buy more wind power and other forms of alternative energy. But many of the municipal utilities will not have the $3 surcharge.
The Michigan Public Service Commission authorized the fees Wednesday. The fees already have been approved for bigger utility companies such as Detroit-based DTE and Jackson-based Consumers Energy.
