4.—(1) For the purposes of regulation 3(3), the relevant amount is—
(a)where sub-paragraph (b) does not apply, the amount of electricity which is the subject of the application under regulation 3(1) which meets the criteria in regulation 3(3)(a) to (c); or
(b)where this paragraph applies the amount given by—
where—
“APF” is the amount of electricity which is the subject of the application under regulation 3(1) which meets the criteria in regulation 3(3)(a) to (c);
“TGE” is the total amount of electricity supplied by all suppliers which meets the following criteria—
the electricity was supplied in the quarterly obligation period in which APF was supplied;
the electricity was the subject of an application under regulation 3(1); and
the electricity meets the criteria in regulation 3(3)(a) to (c);
“CAP” is the amount of the cap which applies in respect of green excluded electricity supplied during that quarterly obligation period.
(2) Paragraph (1)(b) applies where the CFD counterparty determines that TGE exceeds the amount of the cap for the quarterly obligation period in which that electricity was supplied.
(3) For the purposes of this regulation, the cap which applies in respect of green excluded electricity supplied during a quarterly obligation period is—
(a)for each quarterly obligation period in financial year 2015, 1,844,830 MWh;
(b)for each quarterly obligation period in a subsequent financial year, the amount of the cap which applied in the last quarterly obligation period of the previous financial year multiplied by 1.1.
(4) Where the CFD counterparty has determined that an amount of electricity is green excluded electricity but subsequently determines that paragraph (1)(b) applies, or that the relevant amount calculated under paragraph (1)(b) is different to that previously determined, only the relevant amount of electricity as most recently determined constitutes green excluded electricity for the purpose of any subsequent calculation of CFD period contributions under the ESO Regulations.
