Entropy
A measure of unavailable energy in a thermodynamic system.
Feedwater
Total flow supplied to the boiler, sum of condensate and makeup.
Forced outage rate (%)
Forced outages require the removal of a generating unit from service for repairs that have not been planned.
Energy lost due to forced outages (MWh) * 100 divide by:
Total installed capacity (MW) * period hours
Fossil Fuel
Derived from hydrocarbon and includes coal, natural gas, coal seam methane, oil and liquid petroleum gas.
Gas turbine
An engine operating on what is known as the Brayton cycle with continuous steady flow compression of air, constant pressure combustion and expansion of the compressed heated gases through an expansion turbine. Working fluid is usually air, fuels can be gaseous or premium liquid fuels such as distillate.
Generated Energy (MWh)
Electrical energy generated by the power plant.
Greenhouse Gases (GHG)
Those gaseous constituents of the atmosphere, both natural and anthropogenic, that absorb and re-emit infrared radiation.
Greenhouse Intensity (GI)
Measure of Greenhouse efficiency as the emission rate of greenhouse gases from fuel burning expressed in kg CO2 (equiv.) per MWh sent out. For cogeneration, this is discounted for steam/heat production.
