Energy Center Tucson’s plant is located in the heart of downtown Tucson, where it serves six buildings, including the Tucson Convention Center, Midtown Police Station, and Fire Department. The plant was built in 1968 and has been operating for over half a century.

The City of Tucson’s original district energy system was a heating and cooling plant that served municipal buildings via two heating and cooling loops. The system has since expanded to four loops serving 922,000 square feet of building space. The heating and cooling plant’s equipment includes three centrifugal chillers and five boilers, as well as a combined heat and power (CHP) system. CHP capabilities were added in 2004 to serve base heat and thermal load’s for the network’s customers.
