Paragraph 6 Mixed generating stations in the 2019/20 obligation period and subsequent obligation periodsF1

This paragraph applies to a generating station that is a mixed generating station on qualification day in any obligation period (the “previous obligation period”) beginning with the 2018/19 obligation period.

By publication day in the previous obligation period, 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 next obligation period (the “relevant obligation period”) after the previous obligation period.

Where publication day in the 2018/19 obligation period occurs after 1st October 2018, in making the exempt combustion unit estimate for the obligation period starting on 1st April 2019, the Secretary of State must rely on the same information used to calculate the figure referred to in article 11(2) in respect of that obligation period.

Sub-paragraph (5) applies where the number of ROCs issued in respect of relevant electricity generated by the generating station during the relevant obligation period has reached the mixed generating station estimate.

Where the number of ROCs issued in respect of relevant electricity generated by the generating station’s relevant capped combustion units during the relevant obligation period exceeds the capped combustion unit allowance, no more ROCs may be issued in respect of relevant electricity generated by the generating station during the relevant obligation period.

In this paragraph—

• “capped combustion unit allowance” means A x 125,000 ROCs, where A is the number of the generating station’s relevant capped combustion units;

• “mixed generating station estimate” means a number of ROCs equal to the sum of—

  1. (a)

     the capped combustion unit allowance, and

  2. (b)

     the exempt combustion unit estimate;

• “publication day” means—

  1. (a)

     in the 2018/19 obligation period, the later of 1st October 2018 and the day that occurs one month after commencement day;

  2. (b)

     in any subsequent obligation period, 1st October.

• “relevant capped combustion unit” means a capped combustion unit included in the generating station on qualification day;

• “relevant exempt combustion unit” means an exempt combustion unit included in the generating station on qualification day.
