The greenhouse gas emission criteria

2.   Biomass meets the greenhouse gas emission criteria for solid and gaseous biomass—

(a) if the greenhouse gas emissions from its use are equal to, or less than, the relevant target; or

(b) if—

(i) the biomass is used by a post-2013 dedicated biomass station or the biomass is used to generate electricity after 1st April 2020;

(ii) the greenhouse gas emissions from its use are equal to, or less than, the relevant ceiling; and

(iii) the biomass is used in an obligation period in which the average greenhouse gas emissions from the relevant biomass used by the station to generate electricity during that obligation period are equal to, or less than, the relevant target.

Calculating the greenhouse gas emissions

3.   For the purposes of paragraph 2, and subject to paragraph 4, the greenhouse gas emissions from the use of biomass to generate electricity—

(a) is to be calculated by the operator of the generating station using the actual value method or the default value method; or

(b) is 91 grams per mega joule of electricity.

4.   The default value method must not be used to calculate the greenhouse gas emissions from the use of biomass unless—

(a) the biomass was used in a generating station with a total installed capacity of less than one megawatt;

(b) the biomass is described in the first column of the table in Part 4; and

(c) in relation to the biomass, the result of the calculation in paragraph 7 of Part C of Annex 5 to the Renewables Directive is equal to, or less than, zero.

5.   For the purposes of paragraph 4(c), paragraph 7 of Part C of Annex 5 to the Renewables Directive is to be read as if—

(a) for each reference to “biofuel” there was substituted “biomass”; and

(b) the words “or bioliquid” were omitted in each place in which those words occur.

PART 2 Actual value method

6.   Where the greenhouse gas emissions from the use of biomass are calculated using the actual value method the greenhouse gas emissions from the use of the biomass are equal to—

(a) in the case of biomass used by a combined heat and power generating station, ; and

(b) in any other case, .

7.   In paragraph (6)—

(a) is equal to where—

(i) A is the total amount of electricity generated by the generating station during the month; and

(ii) F is the energy content of all of the fuels used in generating that electricity during the month;

(b) is equal to where—

(i) F has the same meaning as in sub-paragraph (a)(ii); and

(ii) H is the energy content of all of the heat supplied to any premises by the generating station during the month; and

(c) is equal to—

(i) where the maximum temperature in degrees kelvin of heat or steam which is (or may be) supplied by the generating station to any premises (“”) is less than 423 degrees kelvin, 0.3546;

(ii) in any other case, ; and

(d) E is the greenhouse gas emissions from the production of the biomass and is to be calculated in accordance with Part C of Annex 5 to the Renewables Directive but as if the following modifications were made to Part C of that Annex:—

(i) in paragraph 1—

(aa) for “and use of transport fuels, biofuels and bioliquids” there was substituted “of biomass”;

(bb) for “E = total emissions from the use of the fuel” there was substituted “E = greenhouse gas emissions from the production of the biomass”; and

(cc) for “ = emissions from the fuel in use” there was substituted “ = zero”;

(ii) in paragraph 2, for the references to “fuels” and “fuel” there was substituted in each case “biomass”;

(iii) paragraphs 3 and 4 were omitted;

(iv) in paragraph 7—

(aa) for each reference to “biofuel” there was substituted “biomass”; and

(bb) the words “or bioliquid” were omitted in each place in which those words occur;

(v) in paragraph 11, for “fuel” there was substituted “biomass”;

(vi) paragraph 13 was omitted;

(vii) in paragraph 14, for “fuel” there was substituted “biomass”;

(viii) for paragraph 16 there was substituted—

“16.   Emission saving from excess electricity from cogeneration shall be taken to be zero.”;

(ix) in paragraph 17, for each reference to “fuel” there was substituted “biomass”;

(x) in paragraph 18—

(aa) for “fuel” there was substituted “biomass”;

(bb) the words “In the case of biofuels and bioliquids,” were omitted;

(cc) before “and residues from processing” there was inserted “residues from aquaculture, arboriculture, fisheries and forestry”; and

(dd) for “fuels” there was substituted “biomass”; and

(xi) for paragraph 19 there was substituted—

“19.   Where material is added to the biomass to act as a binding agent or to reduce the emissions of dust, carbon dioxide, methane or nitrous oxide from the use of the biomass, the material so added shall be considered to have zero life-cycle greenhouse gas emissions, provided that the material so added does not exceed 2% by weight of the biomass.”.

PART 3 Default value method

8.   The greenhouse gas emissions from the use of biomass are calculated using the default value method where the greenhouse gas emissions from the use of the biomass are equal to—

(a) in the case of biomass used by a combined heat and power generating station, ; and

(b) in any other case, .

9.   In paragraph (8)—

(a) , and have the same meaning as in Part 2; and

(b) E, in relation to a type of biomass described in the first column of the table in Part 4, is the number of grams which corresponds to that description in the second column of that table.
