Veolia’s development of a central chilled water plant helps a Philadelphia hospital meet its cooling needs, while eliminating the capital commitment by the client.


With a $24 million capital cost, Veolia designed, financed and built a central chilled water plant at Thomas Jefferson University Hospitals and Thomas Jefferson University. Under a 30-year agree­ment, Veolia owns, operates and maintains the plant to meet the institution’s campus chilled water demand.

Thomas Jefferson University Hospitals and Thomas Jefferson University, a 925-bed hospital and teaching university, are partners in providing excellent clinical and compassionate care for patients in the Philadelphia region. As the institution sought to grow and renew its utility infrastructure, it also required a financing solution to advance the capital improvements. Due to Veolia’s presence in Philadelphia and its reputation as a reliable and effective thermal energy provider through the city’s steam grid, provision of chilled water from Veolia was a natural fit. With Veolia’s financing, engineering and project development support, the institution developed a new central chilled water plant without the upfront capital expense that would have been incurred from self-development.


Veolia owns, operates and maintains the central chilled-water plant consisting of cooling towers, chilled water and condensing water pumps, electric switchgear, emergency generator and 2,750 lineal feet of chilled-water pipe. With 7,000 tons of chilled water production capacity, the plant serves six buildings consisting of 1.7 million square feet of hospital, university and research space via a new underground distribution system. The engineering design included four electric centrifugal chillers with dual compressors and variable frequency drives on each chiller and a custom composite cooling tower.


Veolia fully built the central chilled water system and continues to provide reliability and quality chilled water service to the University and Hospital under a 30-year term. Veolia’s long-term partnership with Thomas Jefferson University Hospital enables the institution to focus on its research efforts and providing quality clinical care to its patients.
