The installation of a new combined heat and power (CHP) system at the Milford Regional Medical Center was executed as a fast track project by Waldron. Milford was looking for cost savings and resiliency for their campus.  The new CHP system included a packaged 800 kW natural gas fired Caterpillar engine and waste heat recovery.  Heat from the jacket water system and the engine exhaust are utilized to produce 15 psig steam for the hospital low pressure system.  Energy from the engine lube oil system was recovered and utilized for the domestic hot water system.  The CHP system will provide operational cost savings and in the event of a power outage, could supplement the emergency diesel engines to provide power to the hospital.  The project was completed in 10 months, from notice to proceed to utility acceptance testing.
