28.—(1) Subject to paragraphs (3) and (5) and article 94, ROCs—
(a)are to be issued in respect of a generating station's RO eligible renewable output in a month, and
(b)must not be issued before the end of the second month following that month.
(2) Where—
(a)electricity was generated—
(i)by a generating station with a total installed capacity of at least 1 megawatt, and
(ii)using biomass (other than animal excreta, bioliquid, landfill gas, sewage gas or waste), and
(b)the greenhouse gas emissions from the use of that biomass are above the relevant target,
ROCs in respect of that electricity must not be issued before the end of the second month following the obligation period in which the electricity was generated.
(3) For the purposes of paragraph (3), the greenhouse gas emissions from the use of biomass must be calculated in accordance with paragraphs 3 to 5 of Schedule 2.
(4) When issuing ROCs in respect of electricity generated in a month by a generating station or, in the case of ROCs certifying the matters within section 32B(5), (6) or (8) of the Act, two or more generating stations, the Authority must—
(a)determine the RO eligible renewable output of that generating station or, as the case may be, those generating stations in that month in accordance with article 29 or 30 (whichever is applicable); and
(b)issue ROCs in respect of that station's or those stations' RO eligible renewable output, the amount of electricity to be stated in each ROC being determined in accordance with articles 31 to 41.
(5) Where the number of megawatt hours of RO eligible renewable output in respect of which ROCs are to be issued does not equate to a whole number of ROCs, the number of megawatt hours is to be rounded to the nearest figure which does so equate (and where there are two such figures, the number of megawatt hours is to be rounded upwards).
(6) In this article, “relevant target” has the same meaning as in Part 1 of Schedule 2.
