The Renewables Obligation Order 2006

Procedure and calculations for issue of ROCs

18.—(1) The Authority shall, when issuing ROCs (other than replacement ROCs which shall be issued in accordance with article 20(4)(b) and (5))—

(a)allocate a number (“the ROC sequence number”) to each ROC issued;

(b)allocate ROC sequence numbers sequentially in ascending numerical order to all the ROCs issued in respect of electricity generated from eligible renewable sources by a particular generating station in a particular month; and

(c)in the case of a generating station which in a particular month generates electricity from eligible renewable sources under or in compliance with a qualifying arrangement, issue ROCs in respect of that month—

(i)firstly to the electricity suppliers to whom article 15(4) or (5) applies in that month on the basis of information provided to it by the nominated person; and

(ii)thereafter, in the event that the generating station generates any electricity from eligible renewable sources in that month other than under a qualifying arrangement or which in that month is not required in compliance with such an arrangement to be made available to the nominated person, to the operator of that generating station.

(2) Where it issues ROCs pursuant to this Part the Authority shall—

(a)determine the amount of electricity which is to be regarded as having been generated from eligible renewable sources by a generating station in a particular month (“the relevant month”) pursuant to article 9;

(b)deduct from the amount determined in accordance with sub-paragraph (a) any electricity in respect of which in the relevant month any of the relevant criteria in article 16 were not satisfied;

(c)determine the amount of electricity which results from the calculations in sub-paragraphs (a) and (b) and round the amount so determined to the nearest megawatt hour (with any exact half megawatt hour being rounded upwards);

(d)determine the number of ROCs which it is appropriate to issue for the amount of electricity determined pursuant to sub-paragraph (c) on the basis that one ROC represents one megawatt hour of electricity; and

(e)issue the appropriate number of ROCs determined pursuant to sub-paragraph (d) to the operator of the generating station or to the electricity supplier as specified in article 15.

(3) Subject to paragraphs (4), (5) and (6), for the purpose of paragraph (2)(a), the Authority shall use in the case of the amounts for “gross output” and “input electricity” (as those two expressions are defined in article 9(7)) either—

(a)the most accurate figures for those amounts which are provided to the Authority at the end of the second month following the end of the relevant month (“the relevant date”); or

(b)where the operator of the generating station satisfies the Authority by the relevant date that it will never be possible for it to provide accurate figures, such figures as are estimated by the operator by the relevant date on a basis agreed in advance by the Authority.

(4) Where figures are neither provided under paragraph (3)(a) nor estimated under paragraph (3)(b), the Authority may, in circumstances which it considers exceptional, accept figures which the operator of the generating station provides after the relevant date.

(5) Where figures are provided under paragraph (3)(a) or accepted under paragraph (4) and, before the Authority makes a determination under paragraph (2)(a), the Authority becomes aware of figures which it considers to be more accurate, the Authority may, where it considers appropriate, accept the later figures and make determinations under paragraphs (2)(a) to (d) on the basis of the later figures.

(6) Where the Authority makes a determination under paragraph (2)(a) on the basis of figures provided under paragraph (3)(a) or accepted under paragraph (4) or (5) and the Authority subsequently becomes aware of figures which it considers to be more accurate, the Authority—

(a)may, where it considers appropriate, accept the later figures and make new determinations under paragraphs (2)(a) to (d); and

(b)shall, where the new determination under paragraph (2)(d) differs from the original determination under that provision, either—

(i)if it has not already issued ROCs under paragraph (2)(e), issue ROCs under that paragraph in accordance with the new determination;

(ii)revoke ROCs in accordance with article 20 where it has issued too many; or

(iii)issue additional ROCs in accordance with paragraph (2)(e) where it has issued too few.

(7) ROCs in respect of the relevant month shall be issued no earlier than the relevant date.
