The first freeway lighting system public-private-partnership (P3) in the U.S. closed on Aug. 24, 2015, with the Michigan Department of Transportation (MDOT) and Freeway Lighting Partners, LLC, (FLP) reaching simultaneous commercial and financial close. In addition to FLP, shortlisted proposers were DTE Energy, Citelum and Energy Systems Group.

MDOT initiated the procurement with a request for letters of interest in July 2013 for replacing 15,000 freeway lights in metro Detroit. According to MDOT, capital costs over two years are $39.6 million and O&M costs during the 13-year operating period are set at $51.6 million, excluding electricity costs.
