CHP Installations and Success Stories

South Oaks Hospital on Long Island installed a combined heat and power system in 1990 to reduce energy costs. The system had a simple payback of less than five years, and continues to generate almost all of their energy needs. The current operating cost is just 6 to 8 cents per kWh, compared to the cost of approximately 12 cents per kWh for electricity purchased from the utility.
This 350,000 square foot hospital contains a psychiatric hospital, a nursing home, and an assisted living facility. The system generates up to 100% of the hospital’s electricity, with the utility providing backup power and on-site boilers providing supplemental steam. Steam output from the system is used for space heating, space cooling, domestic hot water, laundry, and the kitchen.
