3. DETERMINATION OF GHGS USING MEASUREMENT-BASED METHODOLOGIES

Equation 1: Calculation of annual emissions in accordance with Article 43(1):

Equation 2: Determination of average hourly emissions:

Equation 2a: Determination of average hourly GHG concentration for the purpose of reporting in accordance with point 9(b) of Annex X, section 1:

Equation 2b: Determination of average hourly flue gas flow for the purpose of reporting in accordance with point 9(b) of Annex X, section 1:

Equation 2c: Calculation of annual emissions for the purpose of the annual emission report in accordance with point 9(b) of Annex X, section 1:

The following abbreviations are used in Equations 1 to 2c:

The index i refers to the individual operating hour. Where an operator uses shorter reference periods in accordance with Article 44(1), that reference period shall be used instead of hours for these calculations.

GHG Em_total

=

total annual GHG emissions in tonnes

GHG conc_{hourly, i}

=

hourly concentrations of GHG emissions in g/Nm³ in the flue gas flow measured during operation for hour i;

V_{hourly, i}

=

flue gas volume in Nm³ for hour i (i.e. integrated flow over the hour or shorter reference period);

GHG Em_average

=

annual average hourly emissions in kg/h from the source;

HoursOp

=

total number of hours for which the measurement-based methodology is applied, including the hours for which data has been substituted in accordance with Article 45(2) to (4);

GHG conc_average

=

annual average hourly concentrations of GHG emissions in g/Nm³;

Flow_average

=

annual average flue gas flow in Nm³/h.
