Methods for Calculating CHP Efficiency | US EPA

Apr 30, 2021 · The calculation of effective electric efficiency is the CHP net electric output divided by the additional fuel the CHP system consumes over and above what would have been used by a boiler to produce the thermal output of the CHP system. Typical effective electric efficiencies for combustion turbine-based CHP systems range from 50 to 70 percent.
