Cogeneration / Combined heat and Power (CHP) Cogeneration (cogen) through combined heat and power (CHP) is the simultaneous production of electricity with the recovery and utilisation heat.
Calculate the annual cost savings and payback period for a CHP unit to be installed in a Nursing home. Compare energy savings with using an oil-fired heating system. CHP heating output = 44 kW. CHP electrical output = 20 kW.
