4.2.5 Demand Control – Disconnection Volume Estimates
0 | For an Equivalent Meter |
Max ( 0, E – V – A) | For all other MSIDs where a value of E can be calculated |
0 | Otherwise |
E is an estimate of the volume that would have flowed through the MSID without a disconnection, and is calculated in accordance with (in order of preference) 4.2.1(f), 4.2.1(g) or 4.2.1(h) for import meters, or 4.2.2(g) for export meters – where an estimate is required but cannot be calculated, E should equal zero;
V is the estimate of volume reduction achieved through a demand side non-BM STOR as reported by the SVAA in the D0375 data flow (or zero if none was reported). For the avoidance of doubt, any non-BM STOR MSID reported in a D0375 sent by the SVAA will be an Active Import site only. Therefore (if not reported) the Measurement Quantity ID for any Estimated HH Demand Disconnection Volume reported by the SVAA in the D0375 is AI. Where no value of V is available, V should equal zero; and
A is the actual metered value in the Settlement Period, or an estimate calculated in accordance with (in order of preference) 4.2.1(a), 4.2.1(b) or 4.2.1(c) for import meters, or 4.2.2(b), 4.2.2(c) or 4.2.2(d) for export meters – where an estimate is required but cannot be calculated, A should equal zero;
Scenario | Action |
Multiple P0238s |
|
Demand Control Event ID – different LDSO MPID - different | Treat new P0238 as though a new Demand Control Event |
Demand Control Event ID – same LDSO MPID - same | Treat new P0238 as replacement of earlier P0238 |
Demand Control Event ID – different LDSO MPID - same | Treat new P0238 as though a new Demand Control Event |
Demand Control Event ID – same LDSO MPID - different | Treat new P0238 as incremental set of MSIDs to earlier P0238 MSIDs |
Multiple D0375s |
|
In all cases the HHDC first checks a new D0375’s Demand Control Event ID against existing P0238 Demand Control Event Id. Where no corresponding P0238 or where D0375 contains MSIDs that are not in P0238, the HHDC rejects new D0375. HHDC should raise issue with SVAA via the BSC Service Desk. | |
Demand Control Event ID - different | Treat new D0375 as though a new Demand Control Event. |
Demand Control Event ID - same | Treat new D0375 as replacement of earlier D0375. |
4.3 Process Meter Data.
for the Interim Information Volume Allocation the HHDC sends data for all Meter periods for all relevant MSIDs; the data may be actual or estimated.
for the Initial Volume Allocation and subsequent reconciliation(s) the HHDC shall send updates only for this data.

1 The section numbering used in this BSC Procedure must not change in order to keep this document in line with the referencing used in the other BSCPs listed in Section 1.5.
2 Applies to Half Hourly (HH SVA MOA) and/or Non-Half Hourly (NHH SVA MOA)
3 On receipt of any new MDD, the HHDC shall ensure that all MDD affecting the accuracy of Settlement which is manually entered by the HHDC shall be validated against the source data supplied by the SVAA to the HHDC by means of double entry keying before the data is recorded by the HHDC and used in performing its functions.
4 In the event of any dispute as to whether an item of MDD is appropriate or, as the case may be, affects the accuracy of Settlement, the decision of the Panel shall be conclusive.
5 If a Registration Transfer from CMRS, proceed in accordance with BSCP68, Section 3.2
6 The D0155 can be used to inform the HHDC of the Supplier read schedule for SMETS Meters by notifying the Retrieval Method of ‘S’ and an appropriate value of Regular Reading Cycle. If the D0155 is received by the HHDC, there is no need to send D0012.
7 Refer to Appendix 4.2 for rules on when the EAC should be used by the HHDC for data estimation purposes.
8 The SVA MOA shall provide the energisation status at MS or feeder level. If the energisation status is provided at feeder level, the HHDC shall assume that the MS is de-energised if all feeders are de-energised, and energised if one or more feeders is energised
9 The D0155 shall be used to inform the HHDC of the Supplier read schedule for SMETS Meters by notifying the Retrieval Method of ‘S’ and an appropriate value of Regular Reading Cycle.
10 The new HHDC should not send the D0170 flow prior to the HHDC Effective From Date on their D0155 ‘Notification of Meter Operator or Data Collector Appointment and Terms’ flow received from their associated Supplier.
11 This Meter Advance Reconciliation will require historic HH Metered Data from the old HHDC, and the new HHDC shall therefore ensure that step 3.2.4.7 is carried out in time for this data to be received.
12 No further action required for Supplier-serviced Metering Systems
13 This Meter Advance Reconciliation will require historic HH Metered Data from the old HHDC, and the new HHDC shall therefore ensure that step 3.2.4.8 is carried out in time for this data to be received
14 This process can also be used where there is only a CoMC, not a coincident CoS and CoMC.
15 Where there is a CoMC only, the HHDC shall be appointed from the date of the actual CoMC.
16 Where there is a coincident CoS and CoMC, the HHDC shall be appointed from the Supply Start Date (SSD).
17 Meter changes do not normally occur at midnight, therefore the HHDC should estimate consumption (in accordance with Appendix 4.2) from midnight of their appointment date until confirmation of the Meter change is received. To prevent “double counting” of consumption, the HHDC shall use a ‘zero’ advance between midnight on the SSD and the time of the Meter reading provided by the SVA HH MOA.
18 An initial Meter reading is required for a co-incident CoS and CoMC. It is optional for a CoMC only.
19 If the LDSO carried out the energisation then the SVA MOA shall only send the D0139 to the HHDC.
20 If an HHDC is aware that their record of the energisation status of a Metering System is inconsistent with the energisation status of the Metering system on site, the HHDC should notify both the SVA MOA and the Supplier as soon as possible after becoming aware of the inconsistency, by email or another method, as agreed.
21 For Registration Transfers from SMRS to CMRS use process described in BSCP68, Section 3.1
22 For Supplier-serviced Metering Systems, the reconfiguration and replacement processes are set out in REC Metering Operations Schedule.
23 This process shall only be used for multi-feeder sites. Where a single feeder site is to be energised or de-energised, processes 3.3.1 or 3.3.2 shall be used as appropriate.
24 The LDSO may perform this role.
25 The HHDC shall retrieve data from the Meter as soon as possible before historical data is overwritten.
26 The HHDC shall provide data for a re-run authorised and timetabled by the Panel, as required.
27 The HHDC shall transfer the complete active data for a SVA MSID to the HHDA to enable the Supplier to meet its obligations under the SVAA Calendar. The HHDC shall send to the HHDA:
(i) for the Interim Information Volume Allocation, data for all Meter Period Values for all SVA MSIDs, which data may be actual or estimated; and
(ii) for the Initial Volume Allocation and for reconciliations subsequent to Initial Volume Allocation, updates of this data where the data has changed
28 The dataflow(s) to be used shall be those as agreed between the sender and recipients.
29 Where the HHDC has agreed with the relevant Supplier to send consumption data to the ESNA where an exempt supply arrangement exists.
30 HHDCs only need to send the D0010 when the HHDC has actual read data. If data cannot be obtained, then HHDC should not send estimated data to the LDSO.
31 The D0001 ‘Request Metering System Investigation’ can be used to notify the Supplier of the inconsistency if appropriate.
32 Where the inconsistency was identified by a Participant other than the HHDA via the D0235 ‘Half Hourly Aggregation Exception Report’, the Supplier shall send the relevant Participant the resolution of inconsistency report within 5WD of receiving the D0002 ‘Fault Resolution Report or Request for Decision on Further Action’. The Supplier shall use the D0002 for this notification where the Participant initially notified the Supplier of the inconsistency via the D0001 ‘Request Metering System Investigation’.
33 For Measurement Classes F and G, the HHDC should not send the D0036 or D0275 to the LDSO but instead send the D0010 in accordance with the timescales and processes in 3.4.1.12 above.
34 The HHDC should contact and liaise with the Supplier if appropriate.
35 The D0005 ‘Instruction on Action’ should always be sent containing the high level points so that an audit trail can be maintained. For complex cases where the D0005 is not sufficient, or where requested by the HHDC, further details can be given in the fault resolution plan. In these instances the sending of the fault resolution plan should be referred to in the D0005. Any other correspondence between the Supplier, SVA MOA and HHDC which is required to resolve the fault should be sent in a format and by a method agreed by those Participants involved.
36 The Supplier and HHDC should agree whether this will be via normal weekly or monthly reporting, or by a specific report
37An affected MSID is any MSID that an LDSO disconnects due to a Demand Control Event. The period of disconnection should match the length of the DCE as reported by NETSO in its Demand Control Imminent Notification(s), regardless of the actual period of disconnection.
38 Whilst the P0238 is sent by the LDSO to the BSCCo, it should be generated by the LDSO as though it is to be sent direct to Party Agents, i.e. the ‘MPID To’ in the header should reflect the various agents that are intended to receive the file.
39 Please see Appendix 4.2.5 for guidance on populating the D0375.
40 The HHDC should only send a D0375 where it is appointed to at least one MSID listed in the P0238. Where it is not appointed to any affected MSIDs, the HHDC does not need to send a D0375.
41 Demand side Non-BM STOR and DSBR MSIDs will only ever be Active Import MSIDs. Therefore any estimated volumes of reduction reported by the SVAA to the HHDC will be an AI value.
42 These processes can also be used where Suppliers obtain Half Hourly data from SMETS compliant Meters using alternative service providers to the HHDC or DCC
43 Where an exempt supply arrangement exists and the Supplier has not instructed the HHDC to send metered data to the relevant ESCA.
44 The SVA MOA shall decide what proving method is appropriate in conjunction with the HHDC.
45 MS assigned to Measurement Class F, or where Half Hourly data is sourced by the Supplier from a Meter compliant with the SMETS, are exempt from proving tests, except for Complex Sites which are subject to the Complex Site Validation Test.
46 All timescales in this process are undertaken in accordance with Appendix 4.5.
47 In the case of a Registration Transfer from CMRS to SMRS, the proving test shall be performed in accordance with the timescale described in BSCP68, Section 3.2.
48 The HHDC shall use all reasonable endeavours to collect the data for the Settlement Period requested.
49 The SVA MOA does not specify the Settlement Periods to be collected by the HHDC.
50 Described as performing a mini-MAR.
51 ‘Actual’ data means collected Metered Data – ‘A’ flagged – which has successfully passed a main / check data comparison (in accordance with Appendix 4.1.7) and Maximum validation (in accordance with Appendix 4.1.6).
52 For the avoidance of doubt, the data estimation method may be provided using the D0022 Additional Information Field, or by any other method agreed between the HHDC, Supplier and LDSO (e.g. spreadsheets, emails) providing that an audit trail of such information is maintained.
53 That is, an Active Import or Active Export MSID.
54 Ideally this should be the latest Settlement Period for which non-zero data is available. This is to prevent the data from being overwritten in the Meter’s memory before the SVA MOA has had time to collect it.
55 The starting date for this time is either the Date of Meter Installation, the Date of Commissioning, the Effective From Date of the Meter, the Effective Date of a Change of Agent as described in Section 4.6.1, or the date when a Metering System becomes energised where there has been a key field change whilst the Metering System was de-energised, whichever is the later.
56 For the avoidance of doubt, where the MOA has indicated that a Metering System is Complex, then the Complex Site Supplementary Information Form shall be mandatory and the Complex Site mapping details shall not be provided by any means other than the Complex Site Supplementary Information Form.
