7.—(1) The biogas used to generate electricity at an AD installation meets the greenhouse gas criteria if the greenhouse gas emissions from each consignment of biomass used to make the biogas are equal to, or less than, the relevant target.
(2) In this paragraph, “relevant target” means—
(a)in relation to biogas used to generate electricity before 1st April 2020, 66.7 grams per megajoule of electricity;
(b)in relation to biogas used to generate electricity on or after 1st April 2020 but before 1st April 2025, 55.6 grams per megajoule of electricity;
(c)in relation to biogas used to generate electricity on or after 1st April 2025, 50 grams per megajoule of electricity.
8. Subject to paragraph 9, the greenhouse gas emissions from the use of biomass to make biogas are to be calculated using the actual value method or the default value method.
9. The default value method must not be used to calculate the greenhouse gas emissions from the use of biomass to make biogas unless—
(a)the biomass was used in an AD installation with a total installed capacity of less than 1 megawatt;
(b)the biomass and the default greenhouse gas emissions from the production of that biomass are set out in the table in paragraph 11; and—
(c)in relation to the biomass, a calculation made in accordance with paragraph 7 of Part C of Annex 5 to the Renewables Directive produces results which are equal to, or less than, zero.
10. For the purposes of paragraph 9(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.
11. The table containing biomass and the default greenhouse gas emissions from the production of biomass is as follows—
| Biomass | Default greenhouse gas emissions from the production of biomass (in grams) |
|---|---|
| Bagasse briquettes where the process to produce the briquettes was fuelled by wood | 17 |
| Bagasse bales | 20 |
| Palm kernel | 27 |
| Rice husk briquettes | 28 |
| Biogas produced from wheat, where the whole plant was used to produce the biogas | 21 |
| Wheat straw | 2 |
| Biogas produced from straw | 21 |
| Biogas produced from organic maize, where the whole plant was used to produce the biogas | 19 |
