74.—(1) This regulation applies in relation to biomethane produced for injection, or an accredited RHI installation which generates heat from biogas, including additional biomethane or additional RHI capacity, where—

(a) in any payment year, less than 50% of the total biogas yield is derived from waste or residue; and

(b) the tariff start date is—

(i) on or after the date on which these Regulations come into force; or

(ii) on or after 14th December 2016 but before the date on which these Regulations come into force, provided that the participant has elected to be subject to the arrangements set out in this regulation by notice to the Authority no later than 1 month after the date on which these Regulations come into force.

(2) Where this regulation applies, the sum of the periodic support payments for a payment year must be reduced to the amount calculated in accordance with the following formula—

where—

A is the sum of the periodic support payments for biogas or biomethane for that payment year calculated in accordance with regulation 66(2)(b), 67 or 73;

B is the proportion of the total biogas yield for that payment year which is not derived from waste or residue, expressed as a decimal and rounded to four decimal places.

(3) To account for the reduction calculated under paragraph (2), the Authority must—

(a) offset the amount by which the periodic support payments for that payment year have been reduced against periodic support payments in the subsequent payment year; or

(b) where the payment year is the participant's final payment year, require the participant to repay the amount by which the periodic support payments for that payment year have been reduced.

(4) In this regulation—

“biogas yield” means the energy content of any biogas produced by anaerobic digestion which—

(a)

in the case of an accredited RHI installation which generates heat from biogas, is combusted by that installation; and

(b)

in the case of biomethane produced for injection, is an ingredient of that biomethane;

“payment year” means—

(a)

for a participant with a tariff start date on or after the date on which these Regulations come into force, any 12 month period commencing with the tariff start date or the anniversary of the tariff start date;

(b)

for a participant with a tariff start date before the date on which these Regulations come into force—

(i)

the period commencing with the date on which these Regulations come into force and ending with the day before the next anniversary of the tariff start date; and
