The Detroit Public Lighting Department (PLD) currently serves 115 customers, including: Detroit Public Schools; Joe Louis Arena; Cobo Hall; the Detroit Institute of Arts; Wayne State University; McNamara Building Federal Building; and the city’s traffic signal system (almost 1300 intersections). The Detroit Emergency Manager recently notified DTE Energy Company that PLD will be winding down its electricity distribution and transmission services and requested that DTE provide service to PLD’s customers. The switchover will take five to seven years, as DTE will replace the PLD grid over time. How DTE will recover the costs of the transfer and upgrades has become an issue to be decided by the MPSC in Case No. U-17427.
