Multi-hospital academic health system modernizes critical cooling infrastructure without CapEx

The central cooling plant at the health system’s flagship hospital had reached the end of its service life. As its capacity degraded, the hospital relied on rental chillers and generators each summer to keep a 24/7 acute-care facility running through the region’s long cooling season, at a recurring cost of roughly $1 million per summer. The rentals solved nothing structurally, and a failing plant put operational resilience at risk. A permanent fix would require a multimillion-dollar capital outlay, competing with clinical priorities and requiring sign-off from a buying group of more than a dozen stakeholders.

Redaptive aligned the health system’s dozen-plus stakeholders and financed the project through energy-as-a-service (EaaS), preserving capital for clinical priorities and deferring payment until the new plant is complete and accepted. The program ran in sequence: a funded audit to assess the plant’s needs and establish a baseline, financial modeling of outcomes relative to current energy use, and a design to improve efficiency and reliability. Redaptive is managing and delivering the full chiller-plant and cooling-tower modernization, including controls and electrical upgrades, through the customer’s approved vendors, with ongoing performance reporting after completion.

The new plant is being installed without disrupting clinical operations, with resilience built in through N+1 redundancy, directly addressing the risk that prompted the project. By deferring all cash outflows until completion, the EaaS structure is projected to outperform self-funding over the 15-year term while avoiding million-dollar seasonal rental costs through permanent infrastructure. The relationship continues with discussions underway about further efficiency opportunities across the system.
