Section NR 446.10 - Definitions

The definitions contained in ch. NR 400 and in s. NR 446.02 apply to the terms used in this subchapter. In addition, the following definitions apply to the terms used in this subchapter:

(1) "Boiler" means an enclosed combustion device used to produce heat and to transfer heat to recirculating water, steam or other medium.

(2) "Coal-fired" means combusting any amount of coal or coal-derived fuel, alone or in combination with any amount of any other fuel.

(3) "Cogeneration" means an EGU that simultaneously produces both electrical or mechanical, and useful thermal energy from the same primary energy source.

(4) "Combustion turbine" means an enclosed device comprising a compressor, a combustor and a turbine and in which the flue gas resulting from the combustion of fuel in the combustor passes through the turbine, rotating the turbine. If the enclosed device is combined cycle, the combustion turbine includes any associated duct burner, heat recovery steam generator and steam turbine.

(5) "Electric generating unit" or "EGU" means a boiler or a combustion turbine serving a generator that produces electricity.

(6) "Gross electrical output" means electricity made available for use, including any electricity used in the power production process. A power production process includes any on-site processing or treatment of fuel combusted at the EGU and any on-site emission controls.

(7) "Large coal-fired EGU" means an electric generating unit serving a generator with nameplate capacity 150 megawatts and greater.

(8) "Process energy efficiency" means, with regard to cogeneration, the percentage of thermal energy used in the process excluding any energy contained in condensate return, makeup water, and system losses divided by the process internal energy input.

(9) "Process thermal energy input" means, with regard to cogeneration, the total amount of thermal energy made available to a process for use other than for generating electricity.

(10) "Small coal-fired EGU" means an electric generating unit serving a generator with a nameplate capacity greater than 25 megawatts but less than 150 megawatts.

(11) "Useful thermal energy" means, with regard to cogeneration, thermal energy that is any of the following:

(a) Made available to an industrial or commercial process, not a power production process, excluding any heat contained in condensate return or makeup water.

(b) Used in a heating application, such as space heating or hot water heating.

(c) Used in space cooling application, such as thermal energy used by an absorption chiller.
