Cogeneration
11 definitions

Cogeneration
Cogeneration: The production of electrical energy and another form of useful energy (such as heat or steam) through the sequential use of energy.
Cogeneration

Cogeneration: 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

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

Cogeneration

Cogeneration means production of two useful forms of energy such as thermal and electricity from the same process.

Cogeneration

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 onehalf the useful annual thermal energy output equals not less than 42.5 percent of any natural gas and oil energy input.

Cogeneration

Production of two useful forms of energy such as high-temperature heat and electricity from the same process.

Cogeneration

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

The sequential production of electricity and useful thermal energy from a common fuel source. Rejected heat from industrial processes can be used to power an electric generator (bottoming cycle). Conversely, surplus heat from an electric generating plant can be used for industrial processes, or space and water heating purposes (topping cycle).

Cogeneration

A process that sequentially produces useful energy (thermal or mechanical) and electricity from the same energy sources.

Cogeneration

Generally, the use of a single source to provide steam or other energy for an industrial or commercial production o r process AND to generate electricity.
