U-21534-0520

Overview

Energy Michigan filed a reply brief in DTE Electric’s U-21534 rate case challenging DTE’s State Reliability Mechanism capacity charge calculation and Staff’s definition of capacity cost under MCL 460.6w.

Key Points

• •Energy Michigan argued DTE wrongly limited SRM costs to fuel and capacity categories.
• •The brief asserted approximately $260 million labeled as “fuel-related” are non-capacity, non-fuel costs.
• •Energy Michigan claimed DTE’s treatment of these costs improperly inflates the SRM capacity charge.
• •The filing criticized MPSC Staff’s definition of capacity cost as circular and unreliable.
• •Energy Michigan reaffirmed and incorporated positions from its Initial Brief.
