The Michigan Public Service Commission (MPSC) today approved a settlement agreement reconciling Wisconsin Public Service Corporation's 2006 power supply costs.

The settlement agreement found the utility had a net over-recovery that it will refund as follows:  $696,034 will be refunded to its power supply cost recovery (PSCR) customers by lowering its PSCR factor by $0.00398 per kilowatt-hour on bills issued in the billing months of May 2007 through November 2007; and it will refund $76,500 of the over-recovery by implementing a credit of $0.00315 per kilowatt-hour on bills issued in the billing month of December 2007 for all standard tariff metered sales.

The MPSC is an agency within the Department of Labor & Economic Growth.
