is the expression of the conversion efficiency of power plants in the United States and is the amount of heat supplied, in Btu's, to generate 1 kWh of electricity. The smaller the heat rate, the greater the efficiency.
A measure of electric energy system efficiency; the amount of natural gas required to generate one MegaWatt-hour of electric energy .
Energy input per unit of time, usually expressed in kWh\h or BTU\h
A measure of the thermal efficiency of a generating station. It can be computed by dividing the total Btu content of fuel burned for electricity generation by the resulting net kilowatthour generation.
The ratio of fuel energy input as heat per unit of net work output; a measure of a power plant thermal efficiency, generally expressed as Btu per net kilowatt-hour.
The amount of fuel energy required by a power plant to produce one kilowatt-hour of electrical output. A measure of generating station thermal efficiency, generally expressed in Btu per net kWh. It is computed by dividing the total Btu content of fuel burned for electric generation by the resulting net kWh generation. Heat transfer efficiency: useful heat output released to the room actual heat produced in the firebox
a measure of how efficiently an electricity generator converts thermal energy into electricity, and a key determinant of the spark spread. More precisely, the heat rate is the ratio of British thermal units of fuel consumed to kilowatt hours of electricity produced. Hence, the lower the heat rate, the higher the conversion efficiency.
A measure of generating station thermal efficiency commonly stated as Btu per kilowatthour. Note: Heat rates can be expressed as either gross or net heat rates, depending whether the electricity output is gross or net generation. Heat rates are typically expressed as net heat rates.
A measure of the thermal efficiency achieved by a power station.
A number that tells how efficient a fuel–burning power plant is. The heat rate equals the Btu content of the fuel input divided by the kilowatt–hours of power output.
A measure of generating station thermal efficiency and generally expressed as Btu per net k/Wh. The heat rate is computed by dividing the total Btu content of the fuel burned (or of heat released from a nuclear reactor) by the resulting net kWh generated.
