“SCHEDULE 6
Article 28
Annual ROC cap applicable to electricity generated by certain fuelled generating capacity
Interpretation
1 In this Schedule (including the modifications to this Order set out in paragraphs 8 to 18)—
“2018/19 obligation period” means the obligation period starting on 1st April 2018;
“capped combustion unit” means a combustion unit of a relevant fossil fuel station other than any of the following—
(a) an exempt combustion unit;
(b) a combustion unit consisting entirely of generating capacity referred to in article 45(4)(a);
(c) a combustion unit referred to in article 45(4)(d) or (e);
“capped generating station” means a relevant fossil fuel station that includes at least one capped combustion unit and no exempt combustion units;
“commencement day” means the day on which the Renewables Obligation (Amendment) Order 2018 comes into force;
“exempt combustion unit” is to be construed in accordance with paragraph 2;
“mixed generating station” means a relevant fossil fuel station that includes at least one capped combustion unit and at least one exempt combustion unit;
“qualification day” means—
(a) in the 2018/19 obligation period, the later of 1st September 2018 and commencement day;
(b) in any subsequent obligation period, 1st September;
“relevant day” means the first day of the second month after the month in which the Renewables Obligation (Amendment) Order 2018 comes into force;
“relevant electricity” means—
(a) electricity to which article 36 applies;
(b) electricity generated in any of the ways described in Schedule 5 as—
(i) “co-firing of regular bioliquid” (including “co-firing of regular bioliquid with CHP”);
(ii) “high-range co-firing” (including “high-range co-firing with CHP”);
(iii) “low-range co-firing” (including “low-range co-firing with CHP”);
(iv) “mid-range co-firing” (including “mid-range co-firing with CHP”);
(v) “station conversion” (including “station conversion with CHP”); or
(vi) “unit conversion” (including “unit conversion with CHP”);
“relevant fossil fuel station” has the meaning given in Schedule 5, but does not include—
(a) a generating station in relation to which ROCs have been issued in respect of electricity—
(i) generated before the date on which the generating station became a “relevant fossil fuel station” (as defined in Schedule 5); and
(ii) described as “dedicated biomass” (including “dedicated biomass with CHP”) in Schedule 2 to the Renewables Obligation Order 2009 or Schedule 5; or
(b) a microgenerator.
Meaning of “exempt combustion unit”
2.—(1) Subject to sub-paragraphs (2) and (3), a combustion unit of a relevant fossil fuel station is an “exempt combustion unit” for the purposes of this Schedule if it is a combustion unit in relation to which ROCs were issued in respect of electricity—
(a)
(a) generated before 12th December 2014; and
(b)
(b) described in Schedule 2 to the Renewables Obligation Order 2009 as “unit conversion” (including “unit conversion with CHP”) or “station conversion” (including “station conversion with CHP”).
(2) The following are not “exempt combustion units”—
(a)
(a) a combustion unit consisting entirely of generating capacity referred to in article 45(4)(a);
(b)
(b) a combustion unit referred to in article 45(4)(d) or (e).
(3) A combustion unit referred to in sub-paragraph (1) ceases to be an “exempt combustion unit” if, during any 6 month period since commencement day, it generates electricity from fossil fuel, where the energy content of the fossil fuel is more than 15% of the energy content of all of the energy sources used by the unit to generate electricity during that 6 month period.
(4) In sub-paragraph (3), “fossil fuel” does not include fossil fuel for permitted ancillary purposes.
Capped generating stations in the 2018/19 obligation period
3.—(1) This paragraph applies to a generating station that is a capped generating station on commencement day.
(2) No more than A x 125,000 ROCs may be issued in respect of relevant electricity generated by the generating station during the period starting on the relevant day and ending on 31st March 2019.
(3) In sub-paragraph (2), A is the number of capped combustion units included in the generating station on commencement day.
Capped generating stations in the 2019/20 obligation period and subsequent obligation periods
4.—(1) This paragraph applies to a generating station that is a capped generating station on qualification day in any obligation period (the “previous obligation period”) beginning with the 2018/19 obligation period.
(2) No more than A x 125,000 ROCs may be issued in respect of relevant electricity generated by the generating station during the next obligation period after the previous obligation period.
(3) In sub-paragraph (2), A is the number of capped combustion units included in the generating station on qualification day in the previous obligation period.
Mixed generating stations in the 2018/19 obligation period
5.—(1) This paragraph applies to a generating station that is a mixed generating station on commencement day.
(2) By the day one month after commencement day, the Secretary of State must publish an estimate (the “exempt combustion unit estimate”) of the number of ROCs which are likely to be issued in respect of relevant electricity generated by the generating station’s relevant exempt combustion units during the 2018/19 obligation period.
(3) In making the estimate referred to in sub-paragraph (2), the Secretary of State must rely on the same information used to calculate the figure referred to in article 11(2) in respect of the 2018/19 obligation period.
(4) Sub-paragraph (5) applies where the number of ROCs issued in respect of relevant electricity generated by the generating station during the 2018/19 obligation period has reached the mixed generating station estimate.
(5) Where the number of ROCs issued in respect of relevant electricity generated by the generating station’s relevant capped combustion units during the relevant period exceeds...
