When calculating plant heat rate, the energy input to the system is the chemical energy in the fuel. Chemical Energy of Fuel = Total Fuel Used (scf/hr) x Higher Heating Value (HHV)(BTU/scf) The power generated is simply the gross or net generation in kW. If gross generation is used, then the resultant heat rate is the gross unit heat rate.
