PART 2Power purchase agreement scheme

Terms of backstop power purchase agreements

Standard terms of BPPAs

3.  (1)  Any BPPA entered into between a licensed supplier and an eligible generator must include the standard terms which are applicable under paragraph (3) on the date on which the eligible generator enters into the relevant contract.

(2) The standard terms which are issued, revised or amended under paragraph (3) must include provision about the matters which relevant supply licence conditions require to be included in a BPPA.

(3) The Secretary of State-

(a)must issue the standard terms of a BPPA;

(b)may from time to time revise the standard terms issued under sub-paragraph (a) as they apply to eligible generators whose relevant contract is entered into on or after the date specified under paragraph (5)(b) as being the date on which the revision applies; and

(c)if paragraph (4) applies, may amend the standard terms issued under sub-paragraph (a) as they apply to eligible generators whose relevant contract is entered into before the date specified under paragraph (5)(b) as being the date on which the amendment applies.

(4) This paragraph applies where the Secretary of State is satisfied that-

(a)the amendments referred to in that paragraph are necessary in order to take account of a new market structure, trading arrangement or industry code; and

(b)the effect of all of the amendments taken together is such as to maintain so far as possible the balance of risk and reward as between the parties to the BPPA.

(5) The Secretary of State must-

(a)publish the terms which are issued, revised or amended under paragraph (3); and

(b)specify the date on or by reference to which any such term, revision or amendment applies (which must not be earlier than the date on which the term, revision or amendment is published).

(2) Where the OLR application capacity specified in respect of a generating station in an electricity generator's project information is-

(a)less than 100 megawatts, only one BPPA is to be subject to any auction held in respect of the generator;

(b)equal to or exceeds 100 megawatts, two or more BPPAs are to be subject to any auction held in respect of the generator.

(3) In any case falling within paragraph (2)(b)-

(a)the number of BPPAs which are to be subject to an auction held in respect of the electricity generator is to be determined in accordance with paragraphs (4) and (5); and

(b)the capacity in megawatts to which each BPPA relates, is to be determined in accordance with paragraph (6).

(4) The number of BPPAs is to be determined by applying the formula-

where "C" is the OLR application capacity in relation to the generating station.

(5) Where the number resulting from paragraph (4) is not a whole number, that number is to be rounded up or down as follows-

(a)if the first figure after the decimal point is 5 or more, round the number up to the nearest whole number;

(b)otherwise, round it down to the nearest whole number.

(6) The capacity in megawatts to which each BPPA relates is to be determined by dividing the OLR application capacity by the number resulting from the application of paragraphs (4) and (5).

PART 3OLR levelisation and mutualisation

OLR levelisation

OLR levelisation

18.  (1)  With effect from the date on which the Authority is notified that the first BPPA is entered into, the Authority must maintain an account ("the OLR levelisation account")-

(a)into which licensed suppliers are required to pay an amount in accordance with this Part; and

(b)from which payments are to be made by the Authority in accordance with this Part.

(2) The annual levelisation payment which a licensed supplier is required to pay into or receive from the OLR levelisation account is to be calculated under regulation 20.

(3) Paragraph (2) applies in respect of any OLR year only if at least one BPPA is in force for the whole or part of that year.

(4) A periodic levelisation payment which a licensed supplier is required to pay into or receive from the OLR levelisation account is to be calculated under regulation 21.

(5) Paragraph (4) applies in respect of any periodic levelisation period only if at least one BPPA is in force for the whole or part of that period.

Calculations required for purposes of this Part

19.  (1)  Before calculating the annual levelisation payment under regulation 20 in respect of each licensed supplier ("A") in respect of an OLR year, the Authority must make the determinations in relation to A which are required by paragraphs (2) to (5).

(2) The amount of A's "OLR contribution" in respect of an OLR year is to be determined as being the sum of all amounts which, in respect of each BPPA for which A is the OLR, are calculated by applying the formula , where-

(a)V is the volume of electrical output of the electricity generator purchased by the OLR under the BPPA in any period falling within the OLR year during which the BPPA is in force; and

(b)MF is the amount of the management fee which is payable to the OLR under the BPPA during the first 12 months for which the BPPA is in force, expressed as an amount for each megawatt hour of electricity purchased by the OLR.

(3) The amount of A's "adjusted OLR contribution" in respect of an OLR year is to be determined by taking the amount (if any) determined for A under paragraph (2) and adjusting it by-

(a)adding the amounts of any periodic levelisation payments and mutualisation payments made by A in respect of that OLR year; and

(b)subtracting the amounts of any periodic levelisation payments and mutualisation distributions received by A in respect of that OLR year.

(4) The "market share" of A in an OLR year is to be determined by expressing the relevant amount of electricity supplied by A in that OLR year as a percentage of the electricity supply market of Great Britain, where-

(a)"the relevant amount of electricity supplied by A" means the amount of electricity supplied by A to customers in Great Britain;

(b)"the electricity supply market of Great Britain" means the amount of electricity supplied by all licensed suppliers to customers in Great Britain; and

(c)"customer" has the same meaning as in the standard conditions of a supply licence.

(5) The "market share OLR contribution" of A in respect of an OLR year is to be determined by-

(a)calculating the sum of the amounts determined under paragraph (2) in relation to all licensed suppliers; and

(b)multiplying it by the percentage determined in respect of A under paragraph (4).

Annual levelisation payments

20.  (1)  Subject to regulation 18(3), the Authority must, on or before 1st October following the end of each OLR year, calculate the amount which each licensed supplier is entitled to receive from, or required to pay into, the OLR levelisation account in respect of that OLR year as follows.

(2) If the adjusted OLR contribution of a licensed supplier for the OLR year(6) is greater than the licensed supplier's market share OLR contribution(7), the licensed supplier is entitled to receive an annual levelisation payment from the Authority equal to the difference between those amounts.

(3) If the adjusted OLR contribution of a licensed supplier for the OLR year is less than the licensed supplier's market share OLR contribution, the licensed supplier must make an annual levelisation payment to the Authority equal to the difference between those amounts.

Periodic levelisation payments

21.  (1)  The Authority must determine and publish the periodic levelisation periods which are to apply in in respect of each OLR year.

(2) The determination under paragraph (1) must be made-

(a)in respect of the OLR year which ends on 31st March 2016, on or before 1st September 2015; and

(b)in respect of any other OLR year, not later than 1st March in the immediately preceding OLR year.

(3) Each periodic levelisation period must be a period of 3 months or less which falls within the OLR year to which a determination under paragraph (1) relates.

(4) The Authority may vary the periodic levelisation periods which are to apply in an OLR year and must publish notice of any such variation at least one month before the variation takes effect.

(5) Subject to regulation 18(5), the Authority must calculate the periodic levelisation payment which each licensed supplier is required to make or is entitled to receive for each periodic levelisation period.

(6) A calculation under paragraph (5) must be based on the Authority's estimate of the difference between the licensed supplier's OLR contribution(8) and its market share OLR contribution(9) for the OLR year in which the periodic levelisation period falls.

(7) If the OLR contribution of a licensed supplier for the OLR year is estimated to be greater than the licensed supplier's market share OLR contribution, the licensed supplier is entitled to receive a periodic levelisation payment from the Authority equal to the difference between those amounts.

(8) If the OLR contribution of a licensed supplier for the OLR year is estimated to be less than the licensed supplier's market share OLR contribution, the licensed supplier must make an annual levelisation payment to the Authority equal to the difference between those amounts.

Notice of levelisation payments

22.  Where the Authority calculates levelisation payments for any OLR year or periodic levelisation period in accordance with this Part, it must-

(a)give notice to each licensed supplier which is liable to make or entitled to receive a levelisation payment of the amount of that payment; and

(b)where the licensed supplier is liable to make a levelisation payment, specify in the notice the date by which payment is to be made.

Payments by the Authority

23.  (1)  This regulation applies where a licensed supplier is given notice that it is entitled to receive a levelisation payment.

(2) Subject to paragraphs (3) and (5), the Authority must make the levelisation payment as soon as reasonably practicable after the notice is given.

(3) If a licensed supplier fails to make a levelisation payment to the Authority by the date on which it is due ("a late payment"), the Authority may suspend in whole or in part any levelisation payment due to that licensed supplier until the late payment has been made.

(4) Where the late payment is in respect of a periodic levelisation payment and regulation 26 does not apply-

(a)any late payment which the Authority receives before it makes the annual levelisation calculation under regulation 20 in respect of the OLR year in which the period falls is to be included in that calculation; and

(b)any late payment which the Authority receives after it makes that calculation in respect of that year must be distributed in accordance with regulation 28(2).

(5) If the Authority believes that the amount in the OLR levelisation account will not be sufficient to enable it to make a levelisation payment out of the account, the Authority may defer all or part of that payment until there is a sufficient amount in the OLR levelisation account.

Levelisation correction

24.  (1)  Paragraph (2) applies where the Authority identifies that any calculation under regulation 19 or 20(1) is incorrect.

(2) The Authority may, having regard to any payment made or received under regulation 20 or 21, calculate any levelisation payment that each licensed supplier is entitled to receive from, or is required to pay into, the OLR levelisation account in order to correct the error identified under paragraph (1).

(3) After making a calculation under paragraph (2), the Authority must-

(a)give notice to each licensed supplier which is liable to make or is entitled to receive a levelisation payment of the amount of that payment; and

(b)where the licensed supplier is liable to make a levelisation payment, specify in the notice the date by which payment is to be made.

(4) Payments received from licensed suppliers in respect of an OLR year as a result of paragraph (2) are to be distributed in accordance with regulation 28(2).

OLR mutualisation

Trigger for OLR mutualisation

25.  (1)  The Secretary of State must determine in respect of each OLR year a lower limit for the unpaid amounts referred to in paragraph (2)(b) that will trigger a mutualisation ("the mutualisation lower limit").

(2) Regulation 26 applies if-

(a)one or more licensed suppliers fail to make to the Authority the whole or part of a periodic levelisation payment within 5 days of the date on which it is due ("the due date"); and

(b)after 5 days following the due date, the total of unpaid amounts is equal to or greater than the mutualisation lower limit.

(3) In determining the mutualisation lower limit in respect of any OLR year under paragraph (1), the Secretary of State must have regard to-

(a)where the total of unpaid amounts referred to in paragraph (2)(b) falls below the limit determined for that year, the likely effect on any licensed supplier which has entered into a BPPA with an electricity generator of deferring payment under regulation 23(5) of amounts of periodic levelisation payment to which the licensed supplier is entitled; and

(b)where the total of unpaid amounts referred to in paragraph (2)(b) is equal to or above the limit determined for that year, the likely effect on all licensed suppliers of having to make mutualisation payments under regulation 26(2).

(4) The Secretary of State must publish the mutualisation lower limit determined under paragraph (1)-

(a)in respect of the OLR year which ends on 31st March 2016, on or before 30th September 2015; and

(b)in respect of any other OLR year, before the beginning of the OLR year to which it relates.

OLR mutualisation

26.  (1)  In this regulation-

"adjusted market share", in relation to a licensed supplier, is the market share determined in accordance with regulation 19(4) but adjusted to disregard the market share of the defaulting licensed supplier;

"the amount to be mutualised" means the total of unpaid amounts referred to in regulation 25(2)(b);

"defaulting licensed supplier" means a licensed supplier which has failed to make the whole or part of a periodic levelisation payment to the Authority by the date on which it is due;

"qualifying licensed supplier" is a licensed supplier which has made a mutualisation payment under paragraph (2) in respect of the unpaid amount mentioned in paragraph (6);

"unpaid amount" means an amount of a periodic levelisation payment which a defaulting licensed supplier has failed to pay by the date on which it is due.

(2) Where this regulation applies by virtue of regulation 25, the Authority must-

(a)apportion the amount to be mutualised between all licensed suppliers other than the defaulting licensed supplier, in proportion to each licensed supplier's adjusted market share;

(b)give notice to each of those licensed suppliers (a "mutualisation notice")-

(i)that it is liable to make a payment of the amount apportioned to it (a "mutualisation payment"); and

(ii)of the date by which the mutualisation payment is due; and

(c)where paragraph (3) applies, make a distribution of the total amounts received by the Authority (a "mutualisation distribution") to any licensed supplier which-

(i)is not a defaulting licensed supplier; and

(ii)to whom, because of the unpaid amounts, payment of all or part of a periodic levelisation payment to which it is entitled to under regulation 21 has been deferred.

(3) This paragraph applies if-

(a)the date by which the mutualisation payment is due has passed; and

(b)the Authority has received mutualisation payments.

(4) If after giving a mutualisation notice to a licensed supplier, the Authority identifies that any mutualisation payment specified in that notice is incorrect, the Authority must-

(a)cancel that mutualisation notice; and

(b)give a further mutualisation notice under paragraph (2).

(5) Where a mutualisation notice is given to a licensed supplier in accordance with paragraph (4)(b) ("the new notice"), the Authority may treat any mutualisation payment made by that licensed supplier in respect of the cancelled notice as a mutualisation payment made in respect of the new notice.

(6) Where, after receiving mutualisation payments from licensed suppliers, the Authority receives a previously unpaid amount from a defaulting licensed supplier, the Authority must within 20 days distribute that amount among qualifying licensed suppliers in proportion to their adjusted market shares.

(7) Where the Authority receives a mutualisation payment after the date on which it is due-

(a)if the Authority has not made yet made a mutualisation distribution, then this amount is to be included in the distribution; or

(b)if the Authority has made a mutualisation distribution, then this amount is to be distributed in accordance with regulation 28(2).

Miscellaneous

Termination of supply licence

27.  (1)  This regulation applies if the supply licence of a licensed supplier (E) is terminated.

(2) E is not to be regarded as a licensed supplier for the purposes of any periodic levelisation, annual levelisation or mutualisation which takes place after the termination of its licence.

(3) If, before the termination of E's licence, it has been determined on a periodic or annual levelisation under this Part that E is liable to pay or entitled to receive an amount, to the extent that it is unpaid-

(a)E remains subject to that liability but, if the Authority identifies that the calculation of the amount is incorrect, it may adjust the amount and E is liable to pay the adjusted amount (to the extent that it is unpaid);

(b)E remains entitled to that amount but, if the Authority identifies that the calculation of the amount is incorrect, it may adjust the amount and E is entitled to the adjusted amount (to the extent that it is unpaid).

(4) If-

(a)an annual levelisation takes place after the termination of E's licence; and

(b)E had received or paid periodic levelisation payments for the OLR year to which the annual levelisation relates,

the Authority may adjust the annual levelisation payment of each remaining licensed supplier to ensure that the total amount of levelisation payments made or due to be made by licensed suppliers for the OLR year is equal to the total amount of levelisation payments received or due to be received by licensed suppliers for the OLR year.

(5) For the purposes of this regulation, a supply licence is terminated if-

(a)it is revoked by the Authority in accordance with the terms of the licence;

(b)it is surrendered by the licensed supplier; or

(c)it expires by effluxion of time.

Late payments

28.  (1)  This regulation applies when the Authority receives a payment as a consequence of the application of-

(a)regulation 23(4)(b);

(b)regulation 24(2); or

(c)regulation 26(7)(b).

(2) The Authority must distribute the payment to licensed suppliers in proportion to each licensed supplier's market share.

(3) For the purposes of paragraph (2), a licensed supplier's market share is to be calculated in accordance with regulation 19(4) in respect of the OLR year in which the payment was received by the Authority.

(4) The distribution under paragraph (2) must be made on or before 1st October following the end of the OLR year in which the payment was received.

(5) Before making a distribution under paragraph (2), the Authority must give notice to each licensed supplier entitled to receive part of the distribution setting out-

(a)what the distribution relates to; and

(b)the amount the licensed supplier is to receive.

EXPLANATORY NOTE

(This note is not part of the Regulations)

These Regulations apply to Great Britain and make provision for or in connection with a scheme to promote the availability to electricity generators of power purchase agreements ("power purchase agreement scheme"). Other provisions in connection with the power purchase agreement scheme are contained in modifications to the standard conditions of electricity supply licences ("relevant supply licence conditions"). These modifications are made under section 50 of the Energy Act 2013 (c. 32) ("the Act") and are available from the Department of Energy and Climate Change, 3 Whitehall Place, London, SW1A 2AW.

Part 2 (regulations 3 to 17) confers functions on the Gas and Electricity Markets Authority ("the Authority") and the Secretary of State in relation to the operation of the power purchase agreement scheme and sets out the process for determining which persons who hold an electricity supply licence under section 6 of the Electricity Act 1989 ("licensed suppliers") are to offer to enter into agreements with electricity generators under the scheme. Agreements entered into under the scheme are referred to in the Regulations as BPPAs ("backstop power purchase agreements").

Regulation 3 provides that any BPPA entered into by an electricity generator must contain standard terms issued by the Secretary of State which are applicable on the date on which the generator enters into a "relevant contract" (defined as a contract for difference under Chapter 2 of Part 2 of the Act or an investment contract within the meaning of Schedule 2 to the Act). The standard terms must include provision about the matters which relevant supply licence conditions require to be included in a BPPA. Regulation 4 makes provision as to the number of BPPAs which are to be subject to any auction held in respect of the generator.

Regulation 5 makes provision about expressions of interest submitted to the Authority by electricity generators seeking to enter into a BPPA. Unless specified circumstances apply, the Authority is required to send a copy of any expression of interest it receives to all licensed suppliers within 2 working days of receiving it. Regulation 6 requires the Authority to determine whether the eligibility requirements for an electricity generator to enter into a BPPA are met. If those requirements are met, the Authority must issue a notice ("an OLR notice") under regulation 7 and send a copy to all licensed suppliers informing them that a BPPA auction is to be held in respect of the eligible generator. A copy of any BPPA which is to be subject to an auction must be enclosed with the OLR notice. Regulation 8 specifies the period within which the Authority must comply with regulations 6 and 7. The Authority is required by regulations 9 and 10 to inform the generator and licensed suppliers that no BPPA is to be entered into (and to terminate any auction that has already started) in any case where the Authority determines that the eligibility requirements are not met in respect of the generator and in certain other circumstances.

Regulation 11 and the Schedule make provision about the conduct of auctions which relevant supply licence conditions require in order to determine which licensed suppliers are to offer to enter into BPPAs with electricity generators. The Schedule sets out when an auction closes and how the Authority is to determine successful bids. Regulation 12 contains provision about licensed suppliers which are required to participate in auctions which are held in any 12 month period starting on 1 April ("an OLR year").

Regulation 13 makes provision for the suspension in exceptional circumstances of the deadlines within which the Authority is required to discharge specified functions. The Authority must inform licensed suppliers and electricity generators of any delay in discharging the function and specify a new deadline.

Regulation 14 requires the person or persons designated as CFD counterparty for contracts for difference in accordance with section 7 of the Act to provide the Authority with information about relevant contracts entered into by electricity generators. Under regulation 15, licensed suppliers may be required to provide the Authority with information in connection with the power purchase agreement scheme. The Authority has a duty under regulation 16 to maintain records in connection with the operation of the scheme, including records of certain previous conduct in connection with the power purchase agreement scheme which results in a generator being ineligible to enter into future BPPAs in respect of an electricity generating station. The Authority has to report to the Secretary of State on the operation of the power purchase agreement scheme under regulation 17.

Part 3 (regulations 18 to 28) makes provision for a levelisation process which includes mutualisation of certain unpaid amounts. Licensed suppliers are required to make payments to or receive payments from the Authority for the purpose of ensuring that the costs of participating in the power purchase agreement scheme are proportionate to the market shares which the licensed suppliers have in the electricity supply market in Great Britain.

Regulation 18 provides for the Authority to keep an account ("the OLR levelisation account") into which, and from which, are made levelisation payments which are calculated annually and periodically. Regulation 19 requires the Authority to determine certain values and costs for the purposes of calculating annual levelisation payments. These annual levelisation payments are calculated in accordance with regulation 20 and this regulation sets out when such annual payments are to be made into, and paid from, the OLR levelisation account. Under regulation 21, periods for calculating periodic levelisation payments have to be determined by the Authority and the Authority is required to make and receive these periodic levelisation payments on account of annual levelisation payments. Regulation 22 makes provision for the Authority to give notices relating to the making of levelisation payments and regulation 23 deals with the making of such payments by the Authority. There is a correction mechanism under regulation 24 if a calculation made under regulation 20 or 21 is later found to have been incorrect.

Mutualisation is a process by which costs arising from the non-payment of periodic levelisation payments are allocated among all licensed suppliers. If the total of unpaid amounts is equal to or greater than a limit determined by the Secretary of State under regulation 25, the Authority is required by regulation 26 to apportion the unpaid amounts among the licensees and to distribute a mutualisation payment.

Regulation 27 provides what happens in respect of levelisation and mutualisation if, in the course of an OLR year, a licensed supplier has its licence terminated. Regulation 28 provides for the treatment of late mutualisation payments or of late levelisation payments which do not trigger a mutualisation.

Part 4 (regulations 29 to 32) contains miscellaneous provisions. Regulation 29 makes provision for the enforcement of obligations imposed on licensed suppliers by the Regulations. Regulation 30 provides for the Authority to publish guidance in connection with the power purchase agreement scheme. Regulation 31 provides for the Secretary of State to conduct reviews in connection with the scheme. Regulation 32 makes provision about the giving of notices under the Regulations.
