“DSR unproven capacity fee

43ZB.— (1) A capacity provider (“C”) in respect of a demand side response CMU (“CMU i”) must pay to the Settlement Body a fee (a “DSR unproven capacity fee”), by way of financial penalty, if C has in accordance with capacity market rules provided to the Delivery Body a DSR test certificate which evidences CMU i’s proven DSR capacity is an amount less than CMU i’s de-rated capacity.

(2) Where a DSR unproven capacity fee would be payable by C before the T-1 capacity agreement trigger event has occurred, this fee only becomes payable if the T-1 capacity agreement trigger event occurs.

(3) Subject to paragraph (4), the Settlement Body must, as soon as reasonably practicable after receiving notice from the Delivery Body that C has provided a DSR test certificate which gives rise to a DSR unproven capacity fee—

(b) issue to the capacity provider an invoice for that amount.

(4) An invoice under paragraph (3)(b) must only be issued on or after the date on which the T-1 capacity agreement trigger event occurred.

(a) where CMU i’s proven DSR capacity is less than 90% of CMU i’s de-rated capacity, UCF 1; and

(b) where CMU i’s proven DSR capacity is equal to or greater than 90% of CMU i’s de-rated capacity, UCF 2.

(6) In this regulation—

“UCF 1” means an amount equal to £5000 per MW of the amount of the de-rated capacity of CMU i; and
