For Cogeneration we have terms and definitions in 7 topics. The topics are Electric Power, Energy, Environment, Natural Gas, Oil, Uk Power and Wind Energy.

Cogeneration (Electric Power)

The process in which fuel is used to produce heat for a boiler-steam turbine or gas for a turbine. The turbine drives a generator that produces electricity, with the excess heat used for process steam.

Cogeneration (Energy)

Cogeneration means the sequential use of energy for the production of electrical and useful thermal energy. The sequence can be thermal use followed by power production or the reverse, subject to the following standards:
(a) At least 5 percent of the cogeneration project's total annual energy output shall be in the form of useful thermal energy.
(b) Where useful thermal energy follows power production, the useful annual power output plus one-half the useful annual thermal energy output equals not less than 42.5 percent of any natural gas and oil energy input.

Cogeneration (Environment)

The consecutive generation of useful thermal and electric energy from the same fuel source.

Cogeneration (Natural Gas)

The use of a single prime fuel source in a reciprocating engine or gas turbine to generate electrical and thermal energy in order to optimize the efficiency of the fuel used. The dominant demand for energy can be either electrical or thermal. Usually it is the latter with excess electrical energy, if any, being transmitted into the local power supply company's lines (with a reciprocal situation existing when electrical demands exceed the cogeneration plant's output). A parallel exists with total energy plants, which are typically designed for the electrical demands rather than thermal. Under the 1978 Public Utility Regulatory Policies Act (PURPA), regulated utilities are required to purchase electricity furnished by cogenerators and small power producers at rates set by regulatory bodies having jurisdiction over the utility receiving the electricity based on "full avoided cost."

Cogeneration (Oil)

A highly efficient energy system that produces both electricity and heat from one fuel source.

Cogeneration (Uk Power)

The simultaneous production of both useable heat or steam and electricity from a common fuel source

Cogeneration (Wind Energy)

A process that combines the generation of electricity with a separate use of the thermal energy created. For instance, a paper factory might generate its own electricity and use the surplus heat to dry its paper.
