Energy Park Utility Company (EPUC) serves the 218-acre Energy Park community in Saint Paul, MN. Home to manufacturers, commercial/office buildings, schools, health clinics, a hotel, and residential units, Energy Park is one of the nation’s first “Urban Villages.” Since 1980, EPUC has provided heating and cooling services to the majority of the buildings within Energy Park.
Built as a two-pipe system, recent system upgrades to four pipes allow customers to receive heating and cooling services throughout the year, improving the overall energy services and experience for customers while optimizing the efficiency of the district system. Construction included the installation of distribution lines, take-offs, the conversion of customers’ mechanical rooms to optimize system connections, and an expansion of the chilled water system.
