CHP Energy Simulator


	Cogeneration Savings Estimator
	Continuous (24 x 7 x 365) Applications

	The Cogeneration (combined heat and power, CHP) system produces electricity and useful heat. simultaneously. This heat is used for hot water heating, space heating, industrial process heating, dehumidification, or to drive an absorption cooling/air conditioning system. The Cogeneration system is very cost-efficient, often with a payback period of 1 to 4 years. Hospitals, Hotels, and Nursing Homes are excellent candidates for CHP because they have high electrical and thermal energy needs and significant energy demands 24/7/365.

	Use the Cogeneration Estimator to determine the amount of electricity and useful heat that will be supplied (offset) by different systems. Choose a system that closely matches your heating and electricity needs. The Estimator also allows you to compare monthly payments with an all-electric system, determine annual savings and simple payback time.
