Bay City needed to find cost-effective ways of improving key elements of the City’s infrastructure—without having a negative impact on the community’s existing capital and operational budgets. City officials knew that facilities like the wastewater and potable water supply systems, water meter, and municipal lighting systems needed to be upgraded or replaced. To help Bay City meet its infrastructure, energy efficiency, and budget goals, Siemens proposed a 15-year energy performance contract (PC). PC is a procurement methodology that allows the City to retain its capital funds; utilize energy and operational savings, as well as increased revenue, to fund facility improvements; and benefit from guaranteed energy savings through a relationship with a dedicated energy services partner.
