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

Data reconciliation of interim rate payments

8.—(1) This regulation applies where, before the conclusion of a quarterly obligation period, the BSCCo carries out a relevant allocation run in respect of a day in that period and the reconciled interim rate amount in relation to that day for an electricity supplier is different to the net levied interim rate payment for that supplier.

(2) Where that reconciled interim rate amount is more than the net levied interim rate payment the supplier must pay the difference to the revenue collection counterparty.

(3) Where that reconciled interim rate amount is less than the net levied interim rate payment the revenue collection counterparty must pay the difference to the supplier.

(4) The revenue collection counterparty must, as soon as reasonably practicable after the BSCCo has carried out a relevant allocation run in respect of a day, issue a notice to each electricity supplier which states the amount which must be paid by virtue of paragraph (2) or (3).

(5) An electricity supplier who is required to make payment by virtue of paragraph (2) must make that payment by the 5th working day after the day on which the revenue collection counterparty issues the notice to that supplier under paragraph (4).

(6) The revenue collection counterparty must make a payment it is required to make by virtue of paragraph (3) by the 8th working day after the day on which the BSCCo carried out the relevant allocation run following which the revenue collection counterparty is required to make that payment.

(7) Where a supplier fails to pay all or part of a payment it is required to make by virtue of paragraph (2), that supplier must pay the revenue collection counterparty simple interest at the rate specified in regulation 36(1) on any unpaid amount from the day after the day on which that payment should have been made.

(8) For the purposes of this regulation—

(a) the reconciled interim rate amount for a supplier in relation to a day is equal to the amount of electricity supplied by that supplier on that day less any amount of EII excluded electricity supplied by that supplier on that day multiplied by the interim levy rate which applies to that day by virtue of regulation 7(3);

(b) the net levied interim rate payment for a supplier in relation to a day is the sum of the interim rate payment that supplier was required to pay in respect of that day, and any payments that supplier was previously required to pay in respect of that day, by virtue of paragraph (2), less any payments the revenue collection counterparty was previously required to pay to that supplier in respect of that day by virtue of paragraph (3);

(c) a relevant allocation run is an Initial Volume Allocation Run or a Reconciliation Volume Allocation Run; and

(d) the amount of electricity supplied by an electricity supplier on a particular day is the amount of electricity which the BSCCo determines, on the basis of the most recent relevant allocation run in relation to that day, as the amount of electricity supplied by that supplier on that day.
