  "text": "(1) An electricity supplier must make a payment (“an operational cost payment”) to the revenue collection counterparty for each day that supplier makes an electricity supply during an operational cost period.\n(2) The amount of an operational cost payment to be paid by a supplier in respect of 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 operational levy rate.\n(3) The revenue collection counterparty must, as soon as reasonably practicable after the BSCCo has carried out an Initial Volume Allocation Run in respect of a day in an operational cost period, issue a notice to each electricity supplier who supplied electricity on that day stating the operational cost payment which the supplier to whom the notice is issued must pay in respect of that day.\n(4) An electricity supplier must make an operational cost payment in respect of a day by the operational cost payment date in relation to that payment.\n(5) The operational cost payment date in relation to an operational cost payment is the 5th working day after the day on which the revenue collection counterparty has issued a notice under paragraph (3) to the supplier who must make that payment.\n(6) Where an electricity supplier fails to make an operational cost payment by the operational cost payment date in relation to that payment, that supplier must pay the revenue collection counterparty simple interest on any unpaid amount at the rate specified in regulation 36(1) from the day after the operational cost payment date.\n(7) For the purposes of this regulation—\n(a) the operational levy rate is as follows—\n(i) £0.0028 per megawatt hour for any day during the period that begins with 1st April 2025 and ends on 31st March 2026;\n(ii) £0.0063 per megawatt hour for any day during the period that begins with 1st April 2026 and ends on 31st March 2027;\n(iii) £0.0068 per megawatt hour for any day during the period that begins with 1st April 2027 and ends on 31st March 2028;\n(iv) £0.0073 per megawatt hour for any day after 31st March 2028;\n(b) 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 an Initial Volume Allocation Run carried out in relation to that day, as the amount of electricity which that supplier supplied on that day.",
