4.3.3A Each Supplier shall ensure that, in respect of each Settlement Day "T", each GSP Group "H" and each valid combination of Profile Class "P" and Time Pattern Regime within Standard Settlement Configuration "R", the relevant Non Half Hourly Data Collector responsible for a Metering System "K" shall determine a Demand Disconnection Daily Profile Coefficient (DDDPCHPKRT) as:
DDDPCHPKRT = Σj (PPCCHPRj * (MKj / SPD))
where M
Kj shall be set to zero for any
MSID notified under
Section S9.3.1.
4.3.4 Each Supplier shall ensure that a value of Annualised Advance shall be determined from each Meter Advance by the relevant Non Half Hourly Data Collector responsible for each such Supplier’s metered Metering System "K" for each Settlement Register within such Metering System according to the following formula:
where
MADVKR is the
Meter Advance obtained by the relevant
Non Half Hourly Data Collector for the same
Meter Advance Period as employed in the determination of the Fraction of Yearly
Consumption pursuant to
paragraph 4.3.3;
and the Effective From Settlement Date for each such value of Annualised Advance shall be the date of the first Settlement Day in the Meter Advance Period and the Effective To Settlement Date for each such value of Annualised Advance shall be the date of the last Settlement Day in the Meter Advance Period. Such values so determined shall replace any previous Annualised Advance, Effective From Settlement Date and Effective To Settlement Date determined for such Settlement Days.
4.3.6 Each
Supplier shall ensure that for each of its metered
Metering Systems "K", a value for the
Estimated Annual Consumption (
EACKR) shall be determined by the relevant
Non Half Hourly Data Collector responsible for such
Metering System for each
Settlement Register according to the formulae set out in
paragraph 4.3.7.
4.3.7 For the purposes of this
paragraph 4.3.7 the
Previous Estimated Annual Consumption (
PEACKR) shall be defined as the effective value of
EACKR for each
Settlement Day in the
Meter Advance Period which applies before a new value is determined in accordance with this paragraph. An
Annualised Advance Adjustment Factor (
AAAFKR) and a new
Estimated Annual Consumption shall be determined as follows using the value of
Annualised Advance determined pursuant to
paragraph 4.3.4:
(a) AAAFKR = max (0, min ((FYCKR * SPAR), 1.0)); and
(b) EACKR = AAAFKR * AAKR + (1 - AAAFKR) * PEACKR
where SPAR is the value of the Smoothing Parameter set from time to time by the Panel applicable on the last Settlement Day of the Meter Advance Period. The Effective From Settlement Date for each such value of Estimated Annual Consumption shall be the date of the Settlement Day following the last Settlement Day of the Meter Advance Period and shall replace any previous Estimated Annual Consumption effective on such Settlement Days.
4.3.8 Each
Supplier shall ensure that for each of its metered
Metering Systems "K" the
Non Half Hourly Data Collector responsible for such
Metering System shall provide the
Annualised Advance and
Effective From Settlement Date and
Effective To Settlement Date,
Estimated Annual Consumption and
Effective From Settlement Date for each
Settlement Register determined pursuant to
paragraphs 4.3.4 and 4.3.7 to the relevant
Non Half Hourly Data Aggregator responsible for such
Metering System.
4.3.9 In the case where the
Profile Class "P" of a metered
Metering System "K" changes and the
Settlement Day from which the change of
Profile Class is effective does not fall in a
Meter Advance Period, the
Supplier responsible for such
Metering System shall ensure that the
Non Half Hourly Data Collector responsible for such
Metering System shall for each
Settlement Register provide (without adjustment) the initial value of
Estimated Annual Consumption provided pursuant to
paragraph 4.3.2(a) and its
Effective From Settlement Date to the relevant
Non Half Hourly Data Aggregator responsible for such
Metering System. Such value shall on the
Settlement Days it is effective replace the previous
Estimated Annual Consumption effective on such
Settlement Days. Once a
Meter Advance has been calculated such that such change of
Profile Class falls within such
Meter Advance Period, the provisions of
paragraph 4.3.10 shall apply to such
Meter Advance.
4.3.10 In the case where the Profile Class "P" of a metered Metering System "K" changes and the date of the Settlement Day from which the new Profile Class takes effect falls in a Meter Advance Period, then the Supplier responsible for such Metering System shall ensure that the Non Half Hourly Data Collector responsible for such Metering System shall:
(a) determine the value of
Annualised Advance for each
Settlement Register pursuant to the provisions of
paragraphs 4.3.3 to 4.3.4 (inclusive);
(b) not determine a value of Estimated Annual Consumption for any Settlement Register within such Metering System "K" and shall not set such value of Estimated Annual Consumption to zero;
(c) provide the value of
Annualised Advance so calculated together with its
Effective From Settlement Date and
Effective To Settlement Date and send unadjusted the initial value of
Estimated Annual Consumption provided pursuant to
paragraph 4.3.2(a) and its
Effective From Settlement Date to the relevant
Non Half Hourly Data Aggregator responsible for such
Metering System.
4.3.11 In the case where a metered
Metering System "K" is a new
Metering System for which a
Meter Advance has not yet been calculated the
Supplier responsible for such
Metering System shall ensure that the
Non Half Hourly Data Collector responsible for such
Metering System shall set the value of
Estimated Annual Consumption to be equal to the value of initial
Estimated Annual Consumption provided by such
Supplier pursuant to
paragraph 4.3.2(a) for each
Settlement Register and that such
Non Half Hourly Data Collector shall pass such value unadjusted to the relevant
Non Half Hourly Data Aggregator responsible for such
Metering System. The
Effective From Settlement Date for such
Estimated Annual Consumption shall be the
Settlement Day on which such
Metering System is first energised, as determined from data provided by the relevant
SMRA by reference to its
Supplier Meter Registration Service system. The
Supplier shall ensure that the relevant
Non Half Hourly Data Collector shall not determine a value of
Annualised Advance for such
Settlement Register and shall not set the value of
Annualised Advance to zero until a
Meter Advance has been calculated. Once a
Meter Advance has been calculated for such new metered
Metering System, the provisions of
paragraphs 4.3.3 to 4.3.8 (inclusive) shall apply.
4.3.12 In the case where for a metered
Metering System "K" the physical meter changes or, as the case may be, is reconfigured, concurrently with a change to the associated
Standard Settlement Configuration "C" and there is a
Meter Advance Period ending on the
Settlement Day before the physical meter changes or, as the case may be, is reconfigured, the
Supplier responsible for such
Metering System shall ensure that the
Non Half Hourly Data Collector responsible for such
Metering System shall determine the values of
Annualised Advance and
Estimated Annual Consumption for each old
Settlement Register pursuant to
paragraphs 4.3.3 to 4.3.7 (inclusive) and shall provide the
Annualised Advance data together with its
Effective From Settlement Date and
Effective To Settlement Date for such old
Settlement Register and, unadjusted, the initial
Estimated Annual Consumption together with its
Effective From Settlement Date provided by such
Supplier pursuant to
paragraph 4.3.2(a) for each new
Settlement Register to the relevant
Non Half Hourly Data Aggregator responsible for such
Metering System. Such
Non Half Hourly Data Collector shall not be obliged, however, to provide the
Estimated Annual Consumption for the old
Settlement Register determined pursuant to
paragraph 4.3.7 to the relevant
Non Half Hourly Data Aggregator responsible for such
Metering System.
4.3.13 The provisions of this
paragraph 4.3.13 shall apply in the case where there is a
Meter Advance Period ending on the
Settlement Day before there is a change of
Supplier for a metered
Metering System "K" and the metered
Metering System "K" is not subject to half hourly metering on the
Settlement Day of the change of
Supplier. For this purpose a
Meter Advance Period shall end, or as the case may be, shall be deemed to end on such
Settlement Day before the change of
Supplier in accordance with
BSCP504. In this case:
(a) the old Supplier shall ensure that its Non Half Hourly Data Collector responsible for such Metering System shall:
(i) in accordance with BSCP504 and on request from the new Supplier’s Non Half Hourly Data Collector provide the Estimated Annual Consumption for each Settlement Register for such Metering System effective on such Settlement Day to the new Supplier's Non Half Hourly Data Collector responsible for such Metering System;

(ii) ensure that its Non Half Hourly Data Collector responsible for such Metering System shall provide the initial value of Estimated Annual Consumption for each Settlement Register together with its Effective From Settlement Date received pursuant to paragraph (i) above, which values shall be attributable to the new Supplier, to such Supplier's relevant Non Half Hourly Data Aggregators responsible for such Metering System.
4.3.13A The circumstances referred to in
paragraph 4.3.13(c) are that the quantity of energy in respect of the
Metering System is recorded by, and available from, a
Meter:
(a) serviced by the DCC; or
(b) which has been installed in compliance with the
Smart Metering Equipment Technical Specifications and the new
Supplier and the old
Supplier agree that the process in
paragraph 4.3.13(c) shall apply.
4.3.14 The provisions of this
paragraph 4.3.14 shall apply in the case where there is a
Meter Advance Period ending on the
Settlement Day before there is a change of
Supplier for a metered
Metering System "K", and the metered
Metering System "K" is subject to half hourly metering on the
Settlement Day of the change of
Supplier. For this purpose a
Meter Advance Period shall end, or as the case may be, shall be deemed to end on the
Settlement Day before the change of
Supplier in accordance with
BSCP504. In this case, the old
Supplier shall ensure that its
Non Half Hourly Data Collector responsible for such
Metering System shall:
(a) determine the values of
Annualised Advance and
Estimated Annual Consumption for each
Settlement Register for such
Metering System pursuant to
paragraphs 4.3.3 to 4.3.7 (inclusive); and
(b) provide the value of Annualised Advance for each Settlement Register together with its Effective From Settlement Date and Effective To Settlement Date determined pursuant to paragraph (a) above, which values shall be attributable to the old Supplier, to the old Supplier's relevant Non Half Hourly Data Aggregators responsible for such Metering System.
4.3.15 Each Supplier shall ensure that for any metered Metering System "K" for which it is responsible and for which BSCP504 provides that a Deemed Meter Advance must or could be calculated for a Deemed Meter Advance Period such Deemed Meter Advance may (where BSCP504 provides that it may) and shall (where BSCP504 provides it must) be calculated for each Settlement Register in accordance with the following formulae:
(a) Where BSCP504 provides that the Deemed Meter Advance shall be calculated using an Estimated Annual Consumption:
DMAKR = ∑ T (DPCHPRT *EACKR)
ΣT DPCHPRT is the sum of the individual Daily Profile Coefficients appropriate to the GSP Group, Time Pattern Regime, Standard Settlement Configuration and Profile Class applying to the Metering System on each Settlement Day in the applicable Deemed Meter Advance Period as set out in BSCP504.
(b) Where BSCP504 provides that the Deemed Meter Advance shall be calculated using an Annualised Advance:
DMAKR = ∑T (DPCHPRT * AAKR)
ΣT DPCHPRT is the sum of the individual Daily Profile Coefficients appropriate to the GSP Group, Time Pattern Regime, Standard Settlement Configuration and Profile Class applying to the Metering System on each Settlement Day in the applicable Deemed Meter Advance Period as set out in BSCP504.
4.3.16 Where a Deemed Meter Advance has been calculated, each Supplier responsible for a metered Metering System "K" shall ensure that the relevant Non Half Hourly Data Collector responsible for such Metering System shall:
(a) determine values of
Annualised Advance and
Estimated Annual Consumption for each
Settlement Register pursuant to
paragraphs 4.3.3 to 4.3.7 (inclusive) using the value of
Deemed Meter Advance determined pursuant to
paragraph 4.3.15 in place of the value of
Meter Advance and substituting the
Meter Advance Period with the applicable
Deemed Meter Advance Period as described in
BSCP504; and
(b) provide the values of Annualised Advance and/or Estimated Annual Consumption and any further data required to be provided in accordance with BSCP504 to the relevant Non Half Hourly Data Aggregator responsible for such Metering System.
4.3.17 Where a
Meter Advance has been calculated in accordance with
BSCP504 and this has resulted in a new value of
Estimated Annual Consumption which is not consistent with the last valid
Estimated Annual Consumption or
Annualised Advance, as the case may be, then in the circumstances set out in
BSCP504,
paragraph 4.3.7(b) shall not apply and the
Non Half Hourly Data Collector shall apply a value of
Estimated Annual Consumption which is representative of the most likely rate of generation or demand for that
Metering System or, where this is not available, a value of initial
Estimated Annual Consumption (
EACKR). The
Effective From Settlement Date of the value of
Estimated Annual Consumption or initial
Estimated Annual Consumption described above shall be the day following the end of the
Meter Advance Period or
Deemed Meter Advance Period, as the case may be.
4.3.18 Each Supplier shall ensure that each of its Non Half Hourly Data Collectors shall in respect of such Supplier's Unmetered Supplies for which such Non Half Hourly Data Collector is responsible and which are not subject to Equivalent Metering set the values of Estimated Annual Consumption to be those defined in the relevant Unmetered Supply Certificate and shall, in accordance with BSCP520, pass such value unadjusted to the relevant Non Half Hourly Data Aggregator responsible for such Unmetered Supply together with the Effective From Settlement Dates of such Estimated Annual Consumption.

paragraphs 4.3.15 to 4.3.16, and an
Estimated Annual Consumption (
EACKR) for each
Settlement Register (calculated according to the formulae set out in
paragraph 4.3.7), and thereafter for all future calculations replace the
Estimated Annual Consumption (
EACKR) with an
Estimated Annual Consumption (
EACKR) of zero value.
4.3.20 For the purposes of
paragraph 4.3.19, the
Effective From Settlement Date for the use of an
Estimated Annual Consumption (
EACKR) of zero value shall be the earlier of:

NMSSCEDCHPCT = ΣHPCZL NMAHZLPR
where ΣHPCZL is the summation over all Suppliers and Line Loss Factor Classes for any one valid combination of Standard Settlement Configuration and Time Pattern Regime for Standard Settlement Configuration "C" and Profile Class "P" within GSP Group "H";
(c) determine the Profile Class Estimated Daily Consumption (PCEDCHPT) for each Profile Class "P" within each GSP Group "H" for each Settlement Day "T" in the Calculation Period as follows:
PCEDCHPT = ΣHPTC (SSCEDCHPCT * NMSSCEDCHPCT) / ΣHPTC (NMSSCEDCHPCT)
where ΣHPTC is the summation over all Standard Settlement Configurations "C" for Profile Class "P" within GSP Group "H" for Settlement Day "T"; and
(d) determine the GSP Group Profile Class Default Estimated Annual Consumption (GGPCDEACHP) for each Profile Class "P" within each GSP Group "H" as follows:
GGPCDEACHP = ΣHPT PCEDCHPT * Days in Year / DaysHP
where DaysHP is the number of Settlement Days in the Calculation Period for which one or more values of TAAHZLPR was determined for Profile Class "P" within GSP Group "H"; and
ΣHPT is the summation over all Settlement Days "T" for Profile Class "P" within GSP Group "H".
5.1.16 The SVAA shall calculate the Annual Fraction of Yearly Consumption (AFYCHPR) in respect of each Profile Class "P" and Standard Settlement Configuration and Time Pattern Regime combination "R" within each GSP Group "H" as follows:
(a) calculate the Unadjusted Annual Fraction of Consumption (UAFYCHPR) for each Profile Class "P" and Standard Settlement Configuration and Time Pattern Regime combination "R" within each GSP Group "H" in accordance with the following formula:
UAFYCHPR = max ((TPREACHPR / ΣHPCRTPREACHPR), 0.000001);
(b) calculate an Annual Fraction of Yearly Consumption Adjustment (AFYCAHPC) for each Profile Class "P" and Standard Settlement Configuration "C" within GSP Group "H" in accordance with the following formula:
AFYCAHPC = 1 - ΣHPCR UAFYCHPR;
(c) for the Time Pattern Regime and Standard Settlement Configuration combination "R" that has the largest value of Unadjusted Annual Fraction of Consumption (UAFYCHPR) for each Profile Class "P" and Standard Settlement Configuration "C" within a GSP Group "H", calculate the Annual Fraction of Yearly Consumption (AFYCHPR) in accordance with the following formula:
AFYCHPR = UAFYCHPR + AFYCAHPC; and
(d) for each Time Pattern Regime and Standard Settlement Configuration combination "R" for Profile Class "P" and Standard Settlement Configuration "C" within GSP Group "H" other than that to which paragraph (c) applies, calculate the Annual Fraction of Yearly Consumption (AFYCHPR) in accordance with the following formula:

5.3.2 The
SVAA shall ensure that processes are put in place which ensure that the data from time to time supplied to it pursuant to
paragraph 5.3.1 are promptly input into the
Supplier Volume Allocation System.
6.1 Making of determinations
6.1.1 The determinations in this
paragraph 6 shall be carried out by the
SVAA in respect of
Metering Systems and in respect of each
Settlement Day for which it is required to make such determinations and which
Settlement Day occurs on or after the
Go-live Date.
6.1.2 The SVAA shall ensure that processes are put in place which ensure that values of Alternative Average Fraction of Yearly Consumption (AAFYCHPR) notified to the SVAA in accordance with BSCP509 are input promptly into the Supplier Volume Allocation System.
6.2 Derivation of Settlement Register switching times for each Teleswitch Time Pattern Regime
6.2.1 The SVAA shall identify each Teleswitch Time Pattern Regime which is associated with one or more Standard Settlement Configurations of which at least one of such Standard Settlement Configurations:
(a) defines a teleswitched metering configuration; and
(b) is assigned to a Teleswitch Group.
6.2.2 For the purpose of carrying out the processes set out in this
paragraph 6.2 which require the use of
Teleswitch Contact Interval Data, the
SVAA shall employ those
Teleswitch Contact Interval Data which:
(b) are in respect of the UTC Days which start or end at spot times which fall within the Settlement Day then being processed.
(a) the
SVAA has not received
Teleswitch Contact Interval Data pursuant to
paragraph 5.2.3 in respect of one or more of the UTC Days identified pursuant to
paragraph 6.2.2 by the time specified in
BSCP508; or
(b) the SVAA has received the data specified in paragraph (a) by the time specified in BSCP508 but such data does not include Teleswitch Contact Interval Data in respect of each Teleswitch Group,
then the matters required to be determined under this
paragraph 6.2 for the
Settlement Day being processed shall be determined by reference to such default data as
BSCP508 requires to be employed for such purpose.
6.2.4 In respect of each
Teleswitch Time Pattern Regime identified pursuant to
paragraph 6.2.1 within each
Teleswitch Group, the
SVAA shall employ the
Teleswitch Register Rules and
Teleswitch Contact Rules in respect of such
Teleswitch Time Pattern Regime (which have been notified to the
SVAA by each
Supplier required to so notify pursuant to
paragraph 5.1.1) to determine the set of
Teleswitch Intervals associated with such
Teleswitch Time Pattern Regime for the
Settlement Day being processed as follows:
(a) by reference to the
Teleswitch Contact Interval Data in respect of the
Teleswitch Group being processed and the UTC Days identified pursuant to
paragraph 6.2.2, the
SVAA shall:
(i) determine the state of each of the Teleswitch Contacts associated with any such Teleswitch Contact Rule at the start of such Settlement Day; and
(ii) identify each following spot time of the Settlement Day at which any of such Teleswitch Contacts associated with any such Teleswitch Contact Rule change state;
(b) in respect of the spot time that is the start of Settlement Day and each spot time identified pursuant to paragraph (a), the SVAA shall, in chronological order of such spot times:
(i) determine whether each such Teleswitch Contact Rule is satisfied for the period (the "contact period") commencing with such spot time and ending at the earlier of the next following spot time identified pursuant to paragraph (a) and the end of such Settlement Day;
(ii) determine whether each such Teleswitch Register Rule is satisfied for the contact period commencing with such spot time by reference to the results of the determination pursuant to paragraph (i) for the associated Teleswitch Contact Rules;
(iii) (A) if any of such Teleswitch Register Rules is satisfied, determine that the Settlement Register associated with such Teleswitch Time Pattern Regime is recording metered consumption for the contact period; or
(B) if none of such Teleswitch Register Rules is satisfied, determine that the Settlement Register associated with such Teleswitch Time Pattern Regime is not recording metered consumption for the contact period;
(A) the associated Settlement Register commences to record metered consumption at such spot time; or
(B) such spot time is the start of the Settlement Day and such Settlement Register is determined pursuant to this paragraph as recording metered consumption for the contact period commencing at such spot time,
determine that such spot time is an Unadjusted Interval Start Time but, in any other case, such spot time shall not be an Unadjusted Interval Start Time; and
(A) the associated Settlement Register ceases to record metered consumption at such spot time; or
(B) such spot time is the end of the Settlement Day and such Settlement Register is determined pursuant to this paragraph as recording metered consumption for the contact period ending at such spot time;
determine that such spot time is an Unadjusted Interval End Time but, in any other case, such spot time shall not be an Unadjusted Interval End Time; and
(c) the SVAA shall determine each Teleswitch Interval in such Settlement Day as a period starting at an Unadjusted Interval Start Time and ending at the next following Unadjusted Interval End Time.
6.3 Derivation of time pattern data
6.3.1 The
SVAA shall carry out the process set out in this
paragraph 6.3:
(a) for each
Teleswitch Time Pattern Regime in respect of which
Teleswitch Intervals have been determined pursuant to
paragraph 6.2 in respect of such
Settlement Day; and
(b) for each
Time Pattern Regime in respect of which
Clock Intervals have been received by the
SVAA pursuant to
paragraph 5.1.1 and which apply in respect of the
Settlement Day then being processed.
6.3.2 The
SVAA shall update each
Time Pattern Regime identified pursuant to
paragraph 6.3.1 to take account of the associated
Teleswitch Intervals or, as the case may be,
Clock Intervals that apply in respect of the
Settlement Day then being processed.
6.4 Rounding of Time Pattern data
6.4.1 In respect of each
Standard Settlement Configuration, the
SVAA shall calculate a set of
Adjusted Intervals pursuant to this
paragraph 6.4, where subscript "(ai)" refers to a particular
Adjusted Interval, subscript "X" refers to a
Time Pattern Regime and subscript "R" refers to the combination of such a
Time Pattern Regime and such
Standard Settlement Configuration. The determinations set out in
paragraphs 6.4.2 to 6.4.11 (inclusive) shall be carried out by the
SVAA in the sequential order set out in such paragraphs. The determinations set out in
paragraphs 6.4.2 to 6.4.6 (inclusive) shall be carried out in respect of a
Specimen Settlement Day related to the
Settlement Day then being processed and, if required pursuant to such paragraphs, the next following
Specimen Settlement Day related to the
Settlement Day then being processed.
(a) identify all Time Pattern Regimes associated with the Standard Settlement Configuration being processed;
(b) in respect of each such Time Pattern Regime determine each Unadjusted Interval Start Time (UISTX(ai)) as the time identified by reference to such Time Pattern Regime at which Settlement Registers associated with the Time Pattern Regime commence to record Metered Data and if such Settlement Registers are identified as recording Metered Data at the start of the Settlement Day, the start of the Settlement Day shall also be identified as an Unadjusted Interval Start Time;
(c) for each Unadjusted Interval Start Time determined in respect of a Time Pattern Regime pursuant to paragraph (b) determine an associated Unadjusted Interval End Time (UIETX(ai)) as the earlier of:
(i) the next following time, identified by reference to such Time Pattern Regime, at which the Settlement Registers associated with the Time Pattern Regime cease to record Metered Data; and
(ii) the end of the Settlement Day; and
(d) each such period beginning at an Unadjusted Interval Start Time and ending at its associated Unadjusted Interval End Time shall be known as an "Unadjusted Interval".
6.4.3 The SVAA shall identify each spot time of the Settlement Day at which an Unadjusted Interval Start Time or an Unadjusted Interval End Time occurs for one or more of the Time Pattern Regimes associated with the Standard Settlement Configuration being processed.
6.4.4 The
SVAA shall in respect of each spot time identified pursuant to
paragraph 6.4.3 carry out the determinations set out in this
paragraph 6.4.4 save in the case where such spot time occurs at the start of a
Settlement Period or, as the case may be, at the end of the
Settlement Day being processed, in which case the provisions of
paragraph 6.4.6 shall apply. The determinations set out in this
paragraph 6.4.4 or, as the case may require,
paragraph 6.4.6 shall be carried out for each such spot time in turn in chronological order of the occurrence of all such spot times associated with the
Standard Settlement Configuration being processed. For the purposes of this
paragraph 6.4.4 the
Settlement Period within which the spot time under consideration falls shall be denoted as
Settlement Period "J":
(a) the Rounded-Up Spot Time associated with the spot time under consideration shall be determined to be the spot time at the start of the next following Settlement Period "J+1";
(b) the Rounded-Down Spot Time associated with the spot time under consideration shall be determined as the start of the Settlement Period "J";
(c) the Unrounded Duration (UDX(ai)) of each Unadjusted Interval starting or ending at the spot time under consideration shall be determined as the time duration in minutes between its Unadjusted Interval Start Time and its associated Unadjusted Interval End Time. For the avoidance of doubt, the Unadjusted Interval End Time shall be later than the Unadjusted Interval Start Time, and this determination shall therefore result in a value of the Unrounded Duration which is a positive number of minutes;
(d) the Rounded-Up Duration (RUDR(ai)) of each Unadjusted Interval starting or ending at the spot time under consideration shall be determined as follows:
(i) if the
Unadjusted Interval ends at such spot time, the
Rounded-Up Duration of such
Unadjusted Interval shall be the time duration in minutes between its associated
Adjusted Interval Start Time as previously determined pursuant to this
paragraph 6.4.4 and the
Rounded-Up Spot Time associated with such spot time. In the case in which such
Adjusted Interval Start Time is later in time than such
Rounded-Up Spot Time the
Rounded-Up Duration shall be a negative number of minutes and, in any other case, the
Rounded-Up Duration shall be a positive number of minutes; or
(ii) if the
Unadjusted Interval starts at such spot time, the
Rounded-Up Duration of such
Unadjusted Interval shall be the time duration in minutes between the
Rounded-Up Spot Time associated with the spot time under consideration and the Interim
Adjusted Interval End Time determined pursuant to
paragraph 6.4.5. In the case in which such
Rounded-Up Spot Time is later in time than such Interim
Adjusted Interval End Time the
Rounded-Up Duration shall be a negative number of minutes and, in any other case, the
Rounded-Up Duration shall be a positive number of minutes;
(e) the Rounded-Down Duration (RDDR(ai)) of each Unadjusted Interval starting or ending at the spot time under consideration shall be determined as follows:
(i) if the Unadjusted Interval ends at such spot time, the Rounded-Down Duration of such Unadjusted Interval shall be the time duration in minutes between its associated Adjusted Interval Start Time as previously determined pursuant to this paragraph and the Rounded-Down Spot Time associated with such spot time. In the case in which such Adjusted Interval Start Time is later in time than such Rounded-Down Spot Time the Rounded-Down Duration shall be a negative number of minutes and, in any other case, the Rounded-Down Duration shall be a positive number of minutes; or
(ii) if the
Unadjusted Interval starts at such spot time, the
Rounded-Down Duration of such
Unadjusted Interval shall be the time duration in minutes between the
Rounded-Down Spot Time associated with the spot time under consideration and the Interim
Adjusted Interval End Time determined pursuant to
paragraph 6.4.5. In the case in which such
Rounded-Down Spot Time is later in time than such Interim
Adjusted Interval End Time the
Rounded-Down Duration shall be a negative number of minutes and, in any other case, the
Rounded-Down Duration shall be a positive number of minutes;
(f) for every Unadjusted Interval with an Unadjusted Interval Start Time or an Unadjusted Interval End Time which falls at such spot time, a corresponding Adjusted Interval Start Time or, as the case may be, Adjusted Interval End Time shall be determined as follows. For the purpose of making such determinations each of the following paragraphs (i) to (vii) (inclusive) shall be considered in the order set out below. In considering such paragraphs the first such paragraph encountered where the condition specified in such paragraph is satisfied for such spot time shall be employed in the determination of the Adjusted Interval Start Time or, as the case may be, Adjusted Interval End Time and all of the following such paragraphs shall be ignored:
(i) if the number of such Unadjusted Intervals for which RUDR(ai) < 0 is less than the number of such Unadjusted Intervals for which RDDR(ai) <0, then each corresponding Adjusted Interval Start Time and Adjusted Interval End Time shall be determined to be the start time of the next following Settlement Period "J+1";
(ii) if the number of such Unadjusted Intervals for which RUDR(ai) < 0 is greater than the number of such Unadjusted Intervals for which RDDR(ai) < 0, then each corresponding Adjusted Interval Start Time and Adjusted Interval End Time shall be determined to be the start time of Settlement Period "J";
(iii) if the number of such Unadjusted Intervals for which RUDR(ai) = 0 is less than the number of such Unadjusted Intervals for which RDDR(ai) = 0, then each corresponding Adjusted Interval Start Time and Adjusted Interval End Time shall be determined to be the start time of the next following Settlement Period "J+1";
(iv) if the number of such Unadjusted Intervals for which RUDR(ai) = 0 is greater than the number of such Unadjusted Intervals for which RDDR(ai) = 0, then each corresponding Adjusted Interval Start Time and Adjusted Interval End Time shall be determined to be the start time of Settlement Period "J";
(v) if Σ(ai) (RUDR(ai) - UDX(ai))2 < Σ(ai) (RDDR(ai) - UDX(ai))2
then each corresponding Adjusted Interval Start Time and Adjusted Interval End Time shall be determined to be the start time of the next following Settlement Period "J+1";
(vi) if Σ(ai) (RUDR(ai) - UDX(ai))2 > Σ(ai) (RDDR(ai) - UDX(ai))2
then each corresponding Adjusted Interval Start Time and Adjusted Interval End Time shall be determined to be the start time of Settlement Period "J"; or
(vii) in any other case, each corresponding Adjusted Interval Start Time and Adjusted Interval End Time shall be determined to be the start time of Settlement Period "J"; and
(g) if a determination set out in paragraph (f) above in respect of a spot time results in an
Adjusted Interval End Time which falls at the same spot time as the associated
Adjusted Interval Start Time falls, then such
Adjusted Interval End Time shall be re-determined such that it falls at the start time of the next following
Settlement Period and such re-determination shall be made before the next spot time identified pursuant to
paragraph 6.4.3 is processed pursuant to this paragraph.
6.4.5 Where the
SVAA is required pursuant to
paragraph 6.4.4 to determine an Interim
Adjusted Interval End Time in respect of an
Unadjusted Interval, such Interim
Adjusted Interval End Time (AIET
X(ai)) shall be determined as follows:
(a) let the Settlement Period within which the relevant UIETX(ai) falls be identified as Settlement Period J1;
(b) if the duration of the period which begins at the start of Settlement Period J1 and ends at UIETX(ai) is less than half the Settlement Period Duration then the Interim Adjusted Interval End Time shall be set as the start time of Settlement Period J1; and
(c) if the duration of the period which begins at the start of Settlement Period J1 and ends at UIETX(ai) is equal to half the Settlement Period Duration and the start time of Settlement Period J1 is an exact hour then the Interim Adjusted Interval End Time shall be set as the start time of Settlement Period J1;
but in any other case the Interim Adjusted Interval End Time shall be set as the start time of the next following Settlement Period (J1+1).
6.4.6 The provisions of this
paragraph 6.4.6 apply in the case where a spot time identified pursuant to
paragraph 6.4.4 occurs at the start of a
Settlement Period or, as the case may be, the end of the
Settlement Day being processed. In such case then:
(a) for any Unadjusted Interval Start Time which occurs at such spot time its associated Adjusted Interval Start Time shall be determined to be that same spot time; and
(b) for any Unadjusted Interval End Time which occurs at such spot time its associated Adjusted Interval End Time shall be determined to be that same spot time.
6.4.7 If the
Time Pattern Regime is classified as being in "local time" then the
Adjusted Interval Start Times and
Adjusted Interval End Times associated with such
Time Pattern Regime and
Standard Settlement Configuration determined pursuant to
paragraphs 6.4.2 to 6.4.6 (inclusive) shall be construed as being in UK local time on such
Settlement Day "D" or, as the case may be, the next following
Settlement Day "D + 1". For the purposes of this
paragraph 6.4.7 and
paragraph 6.4.9 such next following
Settlement Day "D + 1" is a
Replica Settlement Day related to
Settlement Day "D". The following provisions shall also apply if the
Settlement Day "D" then being processed is a
Settlement Day on which there is a
Clock Change:
(a) if there is an additional (repeated) hour or hours in such Settlement Day "D" as compared with a related Specimen Settlement Day, then any Adjusted Interval Start Time and Adjusted Interval End Time which would as a result of this operation occur at an hour spot time or, as the case may be, half hour spot time that occurs more than once in such Settlement Day shall be construed so that such Adjusted Interval Start Time or, as the case may be, Adjusted Interval End Time occurs at the first occurrence of the hour spot time or, as the case may be, half hour spot time in such Settlement Day "D"; or
(b) if there is an hour or hours fewer in such Settlement Day "D" as compared with a related Specimen Settlement Day, then each Adjusted Interval Start Time and Adjusted Interval End Time which would, if this operation were done in respect of such Specimen Settlement Day, occur at a spot time on such Specimen Settlement Day and which spot time does not exist on the Settlement Day "D", shall be adjusted so that it occurs at the first following spot time on such Settlement Day "D" which does exist.
6.4.8 If the
Time Pattern Regime is classified as being in "GMT" as distinct from "local time" then the
Adjusted Interval Start Times and
Adjusted Interval End Times determined pursuant to
paragraphs 6.4.2 to 6.4.6 (inclusive) shall be construed as being in Greenwich Mean Time. Such times shall then be converted to the corresponding UK local time on the
Settlement Day "D" then being processed, taking due account of any
Clock Change applying to UK local time on such
Settlement Day "D". For the avoidance of doubt such adjustments may result in
Adjusted Interval Start Times or
Adjusted Interval End Times which fall in the next following
Settlement Day "D + 1". For the purposes of this
paragraph 6.4.8 and
paragraph 6.4.9 such
Settlement Day "D + 1" is a
Replica Settlement Day related to
Settlement Day "D".
6.4.9 If any
Adjusted Interval Start Time or
Adjusted Interval End Time determined pursuant to
paragraphs 6.4.2 to 6.4.8 (inclusive) occurs at a spot time in
Settlement Day "D+1", such
Settlement Day being that next following the
Settlement Day, "D", on which the associated
Unadjusted Interval Start Time or, as the case may be,
Unadjusted Interval End Time falls, such
Adjusted Interval Start Time or, as the case may be,
Adjusted Interval End Time shall be modified so that it occurs on
Settlement Day "D" at the same spot time as it had, before such modification, occurred on
Settlement Day "D+1".
6.4.10 An
Adjusted Interval shall be determined as a period of time starting at and including an
Adjusted Interval Start Time and ending on but not including the associated
Adjusted Interval End Time save in the case where a modification has been made pursuant to
paragraph 6.4.9. In such case there shall be two
Adjusted Intervals as follows:
(a) a period of time starting at and including the Adjusted Interval Start Time and ending on but not including the end of the Settlement Day "D"; and
(b) a period of time starting at and including the start time of Settlement Day "D" and ending on but not including the Adjusted Interval End Time associated with such Adjusted Interval Start Time.
6.4.11 In respect of each combination of Time Pattern Regime and Standard Settlement Configuration "R", the SVAA shall determine a Period Time Pattern State Indicator (QRj) for each Settlement Period as follows:
(a) if the start time of such
Settlement Period falls at an
Adjusted Interval Start Time or any time within an
Adjusted Interval associated with such
Time Pattern Regime determined pursuant to this
paragraph 6.4 then:
(b) in any other case QRj = 0.
6.5 Evaluation of Basic Period Profile Coefficients for each Time Pattern Regime
6.5.1 In respect of each GSP Group for each Settlement Day, the SVAA shall determine the Noon Effective Temperature (NETH) as:
NETH = 0.57THT + 0.28THT-1 + 0.15THT-2
where T
HT ,T
HT-1 and T
HT-2 are the
Grid Supply Point Group Measured Temperatures procured from the Temperature Provider pursuant to
paragraph 5.2.2 for
GSP Group "H" in respect of
Settlement Day "D", "D-1" and "D-2" respectively and where
Settlement Day "D" is the then current
Settlement Day,
Settlement Day "D-1" is the immediately preceding
Settlement Day and
Settlement Day "D-2" is the
Settlement Day immediately preceding that designated as "D‑1".
6.5.2 In respect of each
Settlement Day, the
SVAA shall determine the
Sunset Variable (S) from the
Time of Sunset data provided pursuant to
paragraph 5.1.6 as follows:
(a) the Sunset Time (SUNT) in respect of the Settlement Day is the time duration in minutes from the start of the Settlement Day to the time of sunset determined with reference to the Time of Sunset data;
(b) SIX_PM is the time duration in minutes from the start of the Settlement Day to 1800 hours Greenwich Mean Time on that Settlement Day; and
(c) the Sunset Variable (S) shall be determined as:
6.5.3 In respect of each Profile "Q" of each Profile Class "P" within a GSP Group "H", the SVAA shall determine a set of Basic Period Profile Coefficients (PHQj) as set out in paragraphs (a) to (f) (inclusive):
(a) for the purposes of this paragraph the values of MRCQ(aa)(nn)j are the values of the Matrix of Regression Coefficients supplied for the time being and from time to time by the Profile Administrator (or by BSCCo where BSCCo provides the Profile Administration Services in accordance with Section C9) where the subscript "(nn)" represents individual values of MRCQ(aa)(nn)j and such subscript takes values between 0 and 7 inclusive;
(b) for the avoidance of doubt and for the purpose of this
paragraph 6.5 the subscript "j" represents
Settlement Periods of the
Settlement Day. In both of the cases (i) and (ii), the number of
Settlement Periods in respect of which values of
MRCQ(aa)(nn)j are supplied by the
Profile Administrator (or
BSCCo where
BSCCo provides the
Profile Administration Services in accordance with Section C9) may not correspond to the number of
Settlement Periods in the
Settlement Day under consideration. In such cases the values of
MRCQ(aa)(nn)j supplied shall be employed in the determination of values of
Basic Period Profile Coefficient (
PHQj) pursuant to this
paragraph 6.5. Such values of
Basic Period Profile Coefficient shall subsequently be allocated to specific
Settlement Periods of the
Settlement Day under consideration:
(i) in the case of a
Baseload Profile and when there is
Clock Change on the
Settlement Day under consideration only, such allocation shall be made pursuant to
paragraph 6.5.4; or
(ii) in the case of a
Profile associated with switched load such allocation shall be made pursuant to
paragraph 6.6. For the avoidance of doubt, in this case (ii) such allocation may not result in a value of
Basic Period Profile Coefficient for every
Settlement Period in the
Settlement Day;
(c) the
Regression Coefficients (
RCHQ(nn)j) shall be determined as equal to the value of those coefficients
MRCQ(aa)(nn)j which apply in respect of the relevant
Profile "Q" and the
Analysis Class "(aa)" which is identified by the data procured from the
Profile Administrator pursuant to
paragraph 5.1.4 as being relevant to the given
Settlement Day and
GSP Group;
(d) for the avoidance of doubt, a value of RCHQ(nn)j shall not be determined pursuant to paragraph (c) and shall not be set to zero in respect of any Settlement Period "j" for which a value of MRCQ(aa)(nn)j is not defined. This paragraph (d) shall also apply mutatis mutandis in respect of the determinations of values of Estimated Regional Average Demand Per Customer (yHQj) and Basic Period Profile Coefficient pursuant to paragraphs (e) and (f);
(e) the Estimated Regional Average Demand Per Customer (yHQj) shall be determined as:
yHQj = RCHQ0j +( RCHQ1j * MonT )+ (RCHQ2j * WedT)+ (RCHQ3j * ThuT)+ (RCHQ4j * FriT)+ (RCHQ5j * NETH )+ (RCHQ6j * S) +(RCHQ7j * (S)2);
where MonT = 1 if Settlement Day "D" is a Monday or in any other case MonT = 0; and
WedT, ThuT and FriT are determined mutatis mutandis to MonT but as if references to Settlement Day "D" were to a Wednesday, a Thursday or, as the case may be, a Friday; and
(f) in respect of each value of Estimated Regional Demand Per Customer determined pursuant to paragraph (e) a value of Basic Period Profile Coefficient (PHQj) shall be determined as:
PHQj = max(yHQj / (GAACHQ * 2000), 0)
where
GAACHQ is the
Group Average Annual Consumption procured, for the time being and from time to time, from the
Profile Administrator (or from
BSCCo where
BSCCo the
Profile Administration Services in accordance with Section C9) pursuant to
paragraph 5.1.4.
6.5.4 If the
Settlement Day "D" is a
Settlement Day on which there is a
Clock Change then each set of
Basic Period Profile Coefficients corresponding to a
Profile "Q" determined pursuant to
paragraph 6.5.3 shall be modified as follows, save where the
Profile "Q" is a switched load
Profile in which case the relevant set of
Basic Period Profile Coefficients shall not be modified. In the circumstances described in this paragraph, the value of subscript "j" for each value of
Basic Period Profile Coefficient determined pursuant to
paragraph 6.5.3 and which is to be modified pursuant to this paragraph shall, prior to such modification only, denote the
Settlement Period "j" of the related
Specimen Settlement Day to which such value corresponds. The terms "lost", "fewer" and "additional" when applied to hours in the
Settlement Day "D" on which there is a
Clock Change shall be construed as a comparison with such
Specimen Settlement Day:
(a) if there is an hour or hours fewer in the Settlement Day "D" then the relevant Basic Period Profile Coefficients in respect of the Settlement Periods corresponding to the hours lost on such Settlement Day "D" shall be deleted and each such value of the resulting reduced set of Basic Period Profile Coefficients shall be re-labelled with new values of subscript "j" in the same order as the original set so that each value of the set corresponds to a Settlement Period that exists on such Settlement Day "D" and each such Settlement Period is associated with one value of the Basic Period Profile Coefficient set;
(b) if there is an additional (repeated) hour or hours in the
Settlement Day "D" then the relevant
Basic Period Profile Coefficients in respect of the second occurrence of any hour or hours shall be determined by linear interpolation pursuant to
paragraph 3.6 of Annex X-2 save in the circumstances described in paragraph (c) in which case the determination described there shall be performed. The resulting increased set of
Basic Period Profile Coefficients shall be re-labelled with new values of subscript "j" in the same order as the original set with the insertion of the additional values of
Basic Period Profile Coefficient at the appropriate point in the sequence of values to correspond to the second occurrence of any hour or hours so that each value of the set corresponds to a
Settlement Period that exists on such
Settlement Day "D" and each such
Settlement Period is associated with one value of the
Basic Period Profile Coefficient set. For this purpose each
Settlement Period (including those in respect of the second occurrence of any hour or hours) on such
Settlement Day "D" starting from the
Settlement Period immediately preceding the second occurrence of any hour or hours to the
Settlement Period immediately following such second occurrence of any hour or hours shall be labelled in chronological order with ascending equally spaced values of z
n, starting from z
0. For the purposes of
paragraph 3.6 of Annex X-2:
x0 shall take the value of z0;
x1 shall take the value of zN where N is the highest value of n;
each ascending value of xi shall take the next ascending value of zn starting with z1 and ending with zN-1, each corresponding to one of the Settlement Periods for which a value of Basic Period Profile Coefficient is required to be determined, and the related spot value yi shall be the required value of such Basic Period Profile Coefficient;
y0 shall take the value of the Basic Period Profile Coefficient for the Settlement Period labelled z0; and
y1 shall take the value of the Basic Period Profile Coefficient for the Settlement Period labelled zN; or
(c) if there is an additional (repeated) hour or hours in the
Settlement Day "D" and the
Clock Change causing such additional hour(s) takes place at the end of the
Settlement Day "D" then the relevant
Basic Period Profile Coefficients in respect of the second occurrence of any hour or hours shall be determined as follows. The resulting increased set of
Basic Period Profile Coefficients shall be re-labelled with new values of subscript "j" in the same manner as described in paragraph (b). For the purposes of this paragraph (c) each
Settlement Period (including those in respect of the second occurrence of any hour or hours) on such
Settlement Day "D" starting from the
Settlement Period which immediately precedes the
Settlement Period which itself immediately precedes the second occurrence of any hour or hours to the last
Settlement Period of the
Settlement Day "D" shall be labelled in chronological order with ascending equally spaced values of z
n; starting from z
0 . For the purposes of
paragraph 3.6 of Annex X-2:
x0 shall take the value of z0;
x1 shall take the value of z1;
each ascending value of xi shall take the next ascending value of zn starting with z2 and ending with zN where N is the highest value of n, each corresponding to one of the Settlement Periods for which a value of Basic Period Profile Coefficient is required to be determined, and the related spot value yi shall be the required value of such Basic Period Profile Coefficient;
y0 shall take the value of the Basic Period Profile Coefficient for the Settlement Period labelled z0; y1 shall take the value of the Basic Period Profile Coefficient for the Settlement Period labelled z1; and
yi = max( y1 + (y1 - y0) * (i-1), 0).
