Condensed water pumps at CoolCo


District Cooling in Cincinnati

CoolCo provides district energy services to the Central Business District in Cincinnati, Ohio.

CoolCo has served the Cincinnati community since 1997. Currently serving 16 customers including commercial office buildings, retail and hotel facilities, government buildings, and institutional facilities. The CoolCo team is working closely with the City of Cincinnati and local business and sustainability partners to consider future growth and potential for increased efficiency and renewable integration.

Chilled water is generated at a central plant and a satellite plant, capable of producing more than 10,000 tons of cooling. Recent improvements are helping customers save money and energy:

  • High-efficiency cooling towers reduces evaporative drift, which saves water and reduces the plume from the towers
  • New state-of-the-art centrifugal chiller installed in 2019 with a variable frequency drive improves efficiency
  • Control system upgrade in 2017 allows for better system sequencing and energy savings
