The attribution factors for heat and electricity from CHP shall be calculated as follows:
ηheat ηref ;heat
F CHP;heat ¼ η ηel heat ηref ;heat þ ηref ;el
ηel ηref ;el
F CHP;el ¼ η ηel heat ηref ;heat þ ηref ;el
(Equation 40)
(Equation 41)
Where: FCHP,Heat
is the attribution factor for heat (dimensionless);
FCHP,El
is the attribution factor for electricity (or mechanical energy, if applicable) (dimensionless);
ηref, heat
is the reference efficiency for heat production in a stand-alone boiler (dimensionless); and
ηref,el
is the reference efficiency of electricity production without cogeneration (dimensionless).
The appropriate fuel-specific reference efficiencies are given in Annex IX.
The specific emission factor of the CHP-related measurable heat to be used for the attribution of heat-related emissions to production processes shall be calculated as EFCHP,Heat = EmCHP · FCHP,Heat/Qnet
(Equation 42)
Where: EFCHP, heat
is the emission factor for the production of measurable heat in the cogeneration unit expressed in t CO2/TJ; and
Qnet
is the net heat produced by the cogeneration unit expressed in TJ.
The specific emission factor of the CHP-related electricity to be used for the attribution of indirect emissions to production processes shall be calculated as: EFCHP,El = EmCHP · FCHP,El/EEl,prod
(Equation 43)
Where: EEl,prod
is the electricity produced by the CHP unit.
Where a waste gas is part of the fuel mix used, and where the emission factor of the waste gas is higher than the standard emission factor of natural gas given in Table 1 of Annex VIII, that standard emission factor is used to calculate EFmix instead of the emission factor of the waste gas.
C.2.3.
Emission factor of measurable heat produced outside the installation
Where a production process consumes measurable heat produced outside the installation, the heat-related emissions shall be determined using one of the following methods. 1.
Where the installation producing the measurable heat is subject to an eligible monitoring, reporting and verification system, or where the operator of the installation consuming the measurable heat ensures by the means of relevant provisions of the heat delivery contract that the installation producing the heat carries out emission monitoring in line with this Annex, the emission factor of measurable heat shall be determined using relevant equations of Section C.2.1 or C.2.2, based on emission data provided by the operator of the installation producing the measurable heat. 2.
Where the method pursuant to point 1 is not available, a standard value is used, based on the standard emission factor of the fuel most commonly used in the industrial sector of the country, assuming a boiler efficiency of 90 %.
