The Nuclear Regulated Asset Base Model (Revenue Collection) Regulations 2023

Adjusted interim levy rate

12.—(1) Subject to paragraph (2), an adjusted interim levy rate (“adjusted interim levy rate”) for a quarterly obligation period (“the rate period”) is to be determined as the amount given by—

where—

• EOC is the estimated quarterly obligation period payment cost in respect of the rate period, estimated in accordance with regulation 6(1) as at the time of the determination of the adjusted interim levy rate;

• EOI is the estimated quarterly obligation period income in respect of the rate period, estimated in accordance with regulation 6(2) as at the time of the determination of the adjusted interim levy rate;

• SPC is the sum of—

  (a)

  the total amount of interim rate payments which have been received by the revenue collection counterparty in respect of electricity supply during the rate period as at the time of the determination of the adjusted interim levy rate; and

  (b)

  the total amount of interim rate payments which the revenue collection counterparty estimates it will receive in respect of electricity supply during the rate period, in the period from the time of the determination of the adjusted interim levy rate until the adjusted interim levy rate has effect; and

  EPS is the amount of electricity which the revenue collection counterparty estimates will be supplied by all electricity suppliers in that period from the time the adjusted interim levy rate has effect until the conclusion of the rate period, less the amount of EII excluded electricity which it estimates will be supplied by all suppliers in that period.

(2) Where the rate determined in accordance with paragraph (1) would be a negative number, the revenue collection counterparty must determine the adjusted interim levy rate as zero.

(3) Where the revenue collection counterparty has determined an adjusted interim levy rate it must—

(a) as soon as reasonably practicable, publish a notice setting out that rate and issue that notice to every electricity supplier who has a BM Unit registered as at the day before the date of publication of the notice,

(b) issue that notice to every electricity supplier who has a BM Unit that becomes registered on or after the date of publication of the notice and by the last day of the quarterly obligation period during which that rate has effect, as soon as reasonably practicable after the BM Unit is registered; and

(c) where paragraph (5) applies, specify a date on which the rate shall have effect.

(4) Where the adjusted interim levy rate is greater than the previous levy rate, it has effect from the latest of—

(a) the commencement of the rate period;

(b) the 30th day after the revenue collection counterparty has published the notice under paragraph (3);

(c) any later date in the rate period which the revenue collection counterparty specifies in the notice under paragraph (3).

(5) Where the adjusted interim levy rate is less than the previous levy rate, it has effect from the date specified in the notice published under paragraph (3).

(6) For the purpose of paragraphs (4) and (5), “previous levy rate” means the interim levy rate or the adjusted interim levy rate, whichever is most recently determined in respect of the rate period.
