A microgrid uniquely built to serve one of the most advanced health care facilities in the United States


Clearway Community Energy’s Princeton Health System is a state-of-the-art combined heat and power microgrid built to serve Princeton Health System in Plainsboro, New Jersey. Uniquely built to serve one of the most advanced healthcare institutions in the nation, the plant provides the hospital with highly reliable electricity, steam, and chilled water.

The facility is completely energy self-sufficient. It contains three emergency backup generators and 203 kW of on-site solar generation in the form of solar panel carports. A 10,000 ton-hrs ice storage tank assists with cooling during peak hours and reduces energy consumption. Together the plant offers the lowest net energy consumption and highest reliability available to serve a healthcare facility of this size. It eliminates 18.1 million pounds of annual carbon emissions compared to a traditional utility plant.

To remain one of the most advanced healthcare institutions in the nation, Princeton HealthCare System needed a new facility. However, renovating and expanding the existing 93-year-old facility was not a viable option. When the hospital undertook the construction of a new $522 million, 636,000-square foot hospital, Clearway Community Energy proposed and developed a system which would satisfy its needs for continuous, reliable utilities. From start to finish, the CHP solution was designed to meet UMCPP’s specific requirements, and its infrastructure was designed to accommodate future growth.
