The Michigan Public Service Commission (MPSC) today authorized Detroit Edison to reconcile its 2007 power supply costs and its pension equalization mechanism.

The MPSC found that the utility under-recovered $38,235,587 in power supply costs in 2007.  That amount reflects a disallowance of $2.7 million for the extension of the Harbor Beach 1 generating plant outage that occurred in 2007.  The under-recovery is part of the ongoing 2008 reconciliation case.

The MPSC also directed the company to refund to customers $21,361,019, including interest, associated with its pension equalization mechanism in 2007.

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

Case No. U-15002-R
