Power Plant Term Definitions
 Fuel type
- Biogas - Gas produced by processing biomass in an anaerobic digester
- Blast Furnace Gas - (BFG) not to be confused with Coke Oven Gas, associated with steel production.
- Brown Coal - also known as lignite.
- Coal - Generic term when specific type of coal is not known (such as Brown Coal or Hard Coal).
- Coal Water Mixture - (CWM) also called Coal Water Fuels (CWF), a slurry of coal and water.
- Coke Oven Gas - Gas produced by the process of making coke, associated with steel production.
- Diesel Oil - Often used for generators in remote locations.
- Fuel Oil - associated with power plants near refineries.
- Gasoil - specific type of Fuel Oil.
- Hard Coal - also known as anthracite.
- Heavy Fuel Oil - more specific type of Fuel Oil, associated with power plants near refineries.
- Landfill Gas - Methane recovered from landfills, not the same as Biogas
- Municipal Solid Waste
- Naphtha - associated with power plants near refineries.
- Natural Gas
- Ocean Thermal (OTEC) - Ocean Thermal Energy Conversion - The difference in temperature between water on the ocean surface and water much deeper below is used to drive a heat engine.
- Oil - Generic term if no more information is known. Could refer to Diesel Oil, Fuel Oil, or Heavy Fuel Oil.
- Petroleum Coke - associated with power plants near refineries.
- Refuse Derived Fuel
- Residual Fuel Oil - more specific type of Fuel Oil, associated with power plants near refineries.
- Solar Radiation - includes both photovoltaic and concentrated solar power (CSP).
- Waste Heat - Involves the use of waste heat from industrial processes to produce electricity (example). Not very common.
 Cooling method
- air fan - no water cooling is employed
- cooling tower
- fresh water - source of water used in the cooling process.
- sea water - source of water used in the cooling process.
 Power plant use
- electricity only - Heat output of the power plant is not used.
- modern cogen - Typical large-scale industrial combined heat and power (CHP)
- special cogen - A special configuration beyond that of a modern cogen. An example would be a power plant that produces a pure stream of CO2 for industrial purposes in addition to just electricity and heat.
- waste to energy
- horticulture - CHP is used within a greenhouse for heating and production of CO2. Some electricity may be sold to the grid.
- urban heating - Power plant is used for heating within a city.
