This regulation applies where the revenue collection counterparty is of the opinion that there is a high degree of likelihood that it will collect significantly more from suppliers under regulations 7(1) and 10(1) in respect of a quarterly obligation period than the amount it requires to be able to make all payments it is required to make during the reserve period which commences during that quarterly obligation period, taking into account any SoS funds that the Secretary of State has specified will be available in respect of that reserve period and that the Secretary of State has specified should be taken into account when adjusting the total reserve amount.

Subject to paragraph (3), where this regulation applies the revenue collection counterparty may determine again the total reserve amount in respect of that quarterly obligation period in accordance with regulation 9(1)(a) and (6) (the “reduced total reserve amount”).

The revenue collection counterparty may not make a determination under paragraph (2) after the date which is 5 working days before the date on which electricity suppliers must make a reserve payment under regulation 10(1).

The requirement to issue a notice under paragraph (4)(c) does not apply where a notice has been issued under regulation 15(3) in respect of the same obligation period.

Where the revenue collection counterparty issues a notice to a supplier under paragraph (4)(c) and that supplier has already made a reserve payment in respect of the quarterly obligation period to which it relates which exceeds the reduced reserve payment due from that supplier, the revenue collection counterparty must pay back to that supplier the difference between the amount of that reserve payment and the reduced reserve payment now due from that supplier as soon as reasonably practicable.
