1. INTRODUCTION

1.1 Purpose and Scope of the Procedure

This BSCP defines the minimum requirements for the proving of, and the Commissioning End to End Check (CEEC) for, new, and changes to existing, Central Volume Allocation (CVA) Metering Systems. In order to maintain the integrity of Settlement every CVA Metering System is required to go through a full ‘end-to-end’ set of commissioning and Proving Tests when it is first registered for Settlement purposes in the Central Meter Registration Service (CMRS). Commissioning tests and Proving Tests do not necessarily have to be carried out on the same day, provided a reference Settlement Period is identified by the CVA Meter Operator Agent (MOA) for the comparison between Meter Register data and that collected by the Central Data Collection Agent (CDCA) for the same Settlement Period. However, commissioning tests must be completed prior to carrying out a Proving Test, and all testing and sealing completed before the Effective From Date, except where a Supplier Volume Allocation (SVA) Metering System transfers to CVA under BSCP68 (see Section 1.5).

A CEEC shall be carried out on all new CVA Metering Systems and where certain changes to existing CVA Metering Systems are made. The CDCA shall initiate a CEEC data comparison with the Registrant when metered data (consumption or generation, as applicable) is detected for the relevant CVA Metering Subsystem ID (MSSID). A CEEC shall be carried out after commissioning tests and, where applicable, Proving Tests have been carried out.

This Balancing and Settlement Code Procedure (BSCP) differentiates between commissioning tests, Proving Tests and CEECs associated with CVA Metering Systems and defines the boundaries of each activity, as shown in Fig. 1. Commissioning tests, as defined in Code of Practice Four (CoP 4), are the minimum requirements necessary to establish that the CVA Metering Equipment is accurately measuring and recording the energy (consumption or generation) in an Outstation at a Site.

Whilst the general requirements for commissioning tests in relation to the various activities performed on CVA Metering Systems by the CVA MOA which may, or may not, lead to a Proving Test or CEEC being necessary, are covered in the table - Appendix 5: Table of Testing Requirements and Methods of Assurance of Settlement Data and associated Guidance Notes – any detail associated with those commissioning test requirements are out of scope of this procedure, and are not intended to replace the requirements of CoP4.

In Fig. 1, the CVA Metering System is bounded by a thin solid line, and the boundary for ‘commissioning’ by the CVA MOA is shown as a dotted line – Box A.

The purpose of a Proving Test is to establish the following:

(a) The Meter Technical Details (MTD) submitted by the CVA MOA or Registrant to the CDCA to enable data collection are complete, accurate and correctly transferred to the CDCA instation;

(b) The CDCA is able to interrogate the CVA Metering System Outstation and satisfactorily retrieve the relevant metered data in the required format; and

(c) Prove that a Meter register advance for a given Settlement Period is consistent with the metered data retrieved by the CDCA for that same Settlement Period.

The purpose of a CEEC is the following:

The CDCA confirms that metered data being recorded, for the relevant Outstation channel, for the relevant MSSID, is reflective of the amount, and direction, of energy flowing in the primary circuit, related to a CVA Metering System; and
The Registrant confirms that for the relevant Outstation channel, for the relevant MSSID is recording energy with the same order of magnitude, and in the correct direction, to that expected.

The boundary for a Proving Test, carried out by the CDCA in conjunction with the CVA MOA, is shown in Fig. 1 as a thick solid line – Box B.

The boundary for a CEEC, carried out by the CDCA, in conjunction with the Registrant, is shown in Fig. 1 as both the thick solid line (i.e. Box B) and the dotted line (i.e. Box A), and shall include any independent metering equipment (i.e. non-Settlement) used by the Registrant to carry out a data comparison between the metered data recorded for Settlement against either independent metering equipment or, where not practically possible, and with reason(s) provided by the Registrant to the CDCA as to why it was not practically possible, the Registrant can compare the HH readings provided by the CDCA against the expected consumption or generation based on Plant rated capacity and operational load at the time.

This procedure describes the process for determining the requirements for carrying out such Proving Tests, CEECs or other agreed checks on CVA Metering Systems. This procedure also describes the activities involved in carrying out Proving Tests, CEECs, and any additional checks that may be required either at the same time as, or in place of, a Proving Test.

NOTE: CVA MOAs and CDCA should ensure that all recorded readings associated with commissioning and Proving Tests, in accordance with this procedure, are defined in MWh or Mvarh.

CDCA and Registrants should ensure that all recorded readings associated with CEECs, in accordance with this procedure, are defined in MWh or Mvarh.

Proving Tests, CEECs or other agreed checks must use the MTD submitted to the CDCA by the Registrant or CVA MOA in accordance with BSCP20, either via form BSCP20/4.3 ‘Registration of Meter Technical Details’ or the CDCA-I003 ‘Meter Technical Details’. The CVA MOA and CDCA shall not use MTD which are provided by any other method as the basis for a Proving Test, CEEC or other agreed check.

1.1.1 This procedure covers situations where the Registrant or CVA MOA is proposing to:

(a) Install new, or additions to existing CVA Metering Systems;

(b) Remove and / or replace Meters and / or Outstations;

(d) Replace, repair or modify any part of the Metering Equipment associated with a CVA Metering System ; and(e) Change the registration of a Metering System from a Supplier Metering Registration Service (SMRS) to the Central Metering Registration Service (CMRS), i.e. a SVA Metering System becomes a CVA Metering System.

This procedure also covers situations where a third party (other than the Registrant or the CVA MOA), for example the Equipment Owner is proposing to:

(f) Replace, repair or modify any part of the Metering Equipment associated with a CVA Metering System.

Some scenarios will not require a Proving Test to be carried out. Simple comparison checks may be adequate in some circumstances by agreement between the CVA MOA and the CDCA using other relevant metered data from the CVA Metering System collected by the CDCA. Where comparison checks are deemed acceptable the evaluation must take into account the overall integrity of Settlement. These comparison checks will largely be dependent on the degree of duplication within each Metering System.

Other scenarios that are not covered by this procedure may require commissioning and / or a limited degree of Proving Tests. In these cases the CVA MOA should consult with the CDCA and / or BSCCo (Elexon), as appropriate, to agree the scope of testing required. Form BSCP02/4.1 should be used to confirm any agreements between the CVA MOA and CDCA.

Some scenarios will not require a CEEC to be carried out. The requirement for a CEEC will largely be dependent on the degree of duplication within each CVA Metering System; the nature of the work carried out on a CVA Metering System; and whether a CEEC has previously been carried out.

1.1.2 This procedure specifically excludes the requirement for Proving Tests or additional checks for Metering Systems registered in SMRS (these are covered in the Retail Energy Code Metering Operations Schedule).

1.1.3 Proving Tests or additional checks are not required for:

(a) Change of Registrant – since there is no impact on the physical CVA Metering System or associated parameters (unless PINs are changed) - this activity is then covered under reprogramming of Meters / Outstations;

(b) Change of Data Collector – except where there is a transfer of Metering System registration from SMRS to CMRS - since there is only one BSC Agent acting as a Data Collector (CDCA) for CVA Metering Systems.

(c) Change of Meter Operator Agent – since this only requires a registration change by the Registrant, in accordance with BSCP20;

1.2 Objectives

(a) Every new CVA Metering System must go through a full end-to-end set of commissioning and Proving Tests before its registration becomes effective for Settlement purposes, although not necessarily on the same day, provided a reference Period is identified by the CVA MOA for the comparison between Meter Register data and that collected by the CDCA for the same Settlement Period. However, all commissioning tests must be completed prior to carrying out a Proving Test, and all testing must be completed prior to the Effective From Date.

(b) Once Proving Tests are complete, any work on the CVA Metering System must be carried out in such a way as to maintain the integrity of the data entering Settlement and with the prior approval of the CDCA, except in cases of emergency.

(c) Simplified commissioning and Proving Tests may be employed following subsequent work on a CVA Metering System, with agreement of the CDCA / BSCCo provided the integrity of Settlement data can be shown to be maintained.

(d) Where a component part of the CVA Metering System being worked on is fully duplicated, and the duplicate item remains intact, i.e. is not physically changed in any way, then the Proving Tests may be carried out by comparison between the duplicate parts of the CVA Metering System during a complete Settlement Period. In such scenarios the CVA MOA shall submit the Proving Test form to the CDCA. For the avoidance of doubt, where the relevant Section of the BSCP requires a Proving Test form to be submitted and the Proving Test is carried out by a simple dial up, the CVA MOA shall submit the Proving Test form to the CDCA (i.e. Section 3.7 in relation to Ref 14 of Section 5.2.6 for reprogramming an Outstation at system level).

(e) For non-duplicated items acceptable Proving Tests will be required.

(f) Every new CVA Metering System must go through a CEEC.

(g) Where CVA Metering Equipment has been worked on, that CVA Metering System may require a CEEC if the work meets the criteria in Appendix 5 ‘Table of Testing Requirements and Methods of Assurance of Settlement Data’.

1.3 Main Users of the Procedures and their Responsibilities

This procedure should be used by:

(a) CDCA to liaise with CVA MOA in determining requirements, timing and carrying out a Proving Test or comparison checks, and, in conjunction with the CVA MOA, to provide confirmation of a successful Proving Test; and to notify Registrant of the result of a Proving Test; and to liaise with Registrant to carry out a CEEC, and to acknowledge the outcome of the CEEC to the Registrant; and to escalate to BSCCo issues with any CEEC where the Registrant does not respond.

(b) CVA MOA to confirm to the CDCA that the CVA Metering Equipment is fully installed and commissioned, to liaise with the CDCA in determining requirements of a Proving Test or comparison checks, timing of such tests, and, in conjunction with the CDCA, to provide confirmation of a successful Proving Test; and to notify the CDCA where a CEEC is required;

(d) Registrant to receive results of Proving Test, to notify the CDCA where a CEEC is required and complete the CEEC where necessary; and

(e) BSCCo in conjunction with CDCA, to agree the scope of testing required with CVA MOA for scenarios not described in this BSCP, and to agree simplified commissioning and Proving Tests where appropriate; and to deal with CEEC escalations from the CDCA.

1.4 Risk Assessment

Where full end-to-end Proving Tests are not considered to be necessary, as defined in Section 5: ‘Table of Testing Requirements and Methods of Assurance of Settlement Data’, a risk assessment should be carried out to confirm that any reduction in testing will not involve any tangible risk to the accuracy of the Settlement process.

The risk assessment should include the following requirements:

(i) Confirmation that the combined commissioning and Proving Test(s) will provide a high level of assurance that the changes that have been carried out to the CVA Metering System(s) are correct, the CVA Metering System is functioning correctly and is compliant with the relevant Metering Code of Practice;

(ii) The communications equipment is installed and operating correctly;

(iii) The changes resulting from a modification to the MTDs have been correctly applied by the CDCA; and

(iv) Any components of the CVA Metering System not directly affected, but which interface with any physical changes being made, or could indirectly be disturbed by the physical changes, are fully tested to provide a high level of assurance that all aspects of the CVA Metering System are functioning correctly.

The risk assessment should be developed from the pretext that full commissioning and Proving Tests are always necessary. Individual elements of these tests should then be considered on the basis of the level of assurance they provide in the end-to-end testing process. Where each testing element is assessed as not providing any additional assurance or the required level of assurance is provided by other functional tests, the CVA MOA must state why these tests are not necessary in the risk assessment.

In all situations the CVA MOA shall take a risk adverse stance and shall carry out any tests where there is doubt about the need to do so. The CVA MOA should always support the CDCA in proving that the central systems are processing metered data correctly.

1.5 Key Milestones

The key milestones in this procedure are:

For new CVA Metering Systems / additions to CVA Metering Systems - satisfactory completion of Commissioning Tests and Proving Tests at least 8 WD prior to the Effective From Date, as registered in accordance with BSCP20;
For existing commissioned and proven Metering Systems in SMRS which are being transferred into CMRS – satisfactory completion of CVA Proving Tests within 5 WD of the Effective From Date;
For all other work – as soon as practicable, recognising the importance of maintaining integrity of Settlement data.

4 APPENDICES

The following forms and table should be used in conjunction with Section 3: Interface and Timetable Information.

Forms

BSCP02/4.1: Confirmation of Discussion / Testing Requirements with CDCA

Form 4.1 should be used whenever a method of assurance is proposed which deviates from the methods defined in the BSCP.

BSCP02/4.2: Metering System Commissioning Test Record

a – Dial Advance Tests (Primary Outstation)

b – Dial Advance Tests (Secondary Outstation)

Form 4.2 is included within this BSCP in recognition that a dial advance record is required as part of the full ‘end-to-end’ commissioning and Proving Tests required on a new installation. The form ensures consistency of record keeping.

BSCP02/4.3: Metering System Proving Test Record

Form 4.3 should be used to record and sign-off all Proving Tests which are carried out. Information recorded in Form 4.2 as part of the commissioning process may be used to populate the fields in Form 4.3.

BSCP02/4.4: Confirmation of Installation of Metering Equipment (including Extension or Modification of Metering System)

Form 4.4 is the official certificate provided by the CVA MOA, on behalf of the Registrant, that the CVA Metering System has been installed and commissioned in accordance with the Meter Technical Details forwarded to the CDCA.

BSCP02/4.5: Risk Assessment

Form 4.5 should be used by the CVA MOA to identify the proposed work to be carried out, the component parts of the CVA Metering System involved, the potential risks and impact of that work on data quality, and the controls employed to mitigate against those risks.

BSCP02/4.6: Metering System Commissioning End to End Check Test Record Form 4.6 should be used by the Registrant to confirm to the CDCA the method of data comparison used for the CEEC and whether the results of the data comparison are satisfactory (i.e. within the allowed tolerances dependant on the method used). It shall also be used by the Registrant to provide details of a Rectification Plan, if applicable, and to request Settlement Data for a different demand period than that originally provided by the CDCA. The CDCA shall use the form to acknowledge to the Registrant the result of the data comparison and provide the Registrant with any comments.

A Dial Advance Tests

The purpose of this test is to ensure that UPI and dial values set in the Outstation(s) align with the meter. All additional commissioning tests required by CoP4 will have been completed.

	Primary Outstation (if separate from Meter)	Secondary Outstation^² (if separate from Meter)
Check UPI values in Outstation align with the meters.
Check dial values in Outstation align with the meters.

Dial advance tests should then be performed under conditions of injection test where appropriate. In order to achieve sufficient resolution, dial advances equivalent to operating the Meter at rated voltage and current for at least 10 minutes should be achieved.

* This column is for use by the CVA MOA to confirm that the Meter is functioning correctly. It is not an accuracy test. The value may differ from the Meter advance for a number of reasons, e.g. Meter compensation, changes in load when carried out against prevailing load conditions, or the method of estimating the injected energy.

5.5 Guidance Notes

1. Where commissioning is required, it must always be done before any Proving Tests or Commissioning End to End Check that may be required.

2. Where two or more activities are undertaken simultaneously, then commissioning and Proving Tests will be carried out to the highest of the applicable requirements, e.g. where a Meter with integral Outstation is changed then it is necessary to carry out a Proving Test.

3. Data used in commissioning can be used for proving at a later date (subject to Outstation data retention).

4. Any deviations or exceptions to the requirements in Section 5 must be agreed between the CVA MOA, the CDCA and BSCCo as appropriate.

5. Where comparison tests against prevailing load are required and it is not practical to do so, then a secondary injection test shall be substituted. Secondary injection tests shall not be used as part of the CEEC.

6. A risk assessment and method statement shall be carried out by CVA MOA/CDCA where identified in Section 5.

7. When reprogramming an Outstation at channel level, for non-duplicate systems, an injection test is required on all channels. For duplicate systems, where it is necessary to reprogram both Outstations, an injection test is required for those channels changed, for other channels, a comparison test is carried out on a half hour period after reprogramming the first Outstation, then, after waiting a further half hour, the second Outstation may be reprogrammed and the comparison test repeated for the second Outstation.

8. The requirements given in this table are the minimum acceptable to confirm that the quality of data in the Settlements system is maintained. More onerous tests may be carried out at the discretion of the CVA MOA or where the risk assessment indicates.

9. A Commissioning End to End Check shall be carried by the Registrant in conjunction with the CDCA where identified in Section 5.

10. For references 3, 5 to 10, and 11 to 14, only where there is a Duplicate System, a CEEC only needs to be performed if both Meters/Outstations are changed or re-programmed; and if one Meter/Outstation is replaced or re-programmed and the other unaffected Meter/Outstation has not previously completed a CEEC.

11. For references 15 to 19, and 23 to 25 a CEEC only needs to be performed where one has not previously been completed. Registrant can request that all MSSIDs under the MSID shall have a CEEC performed.

12. For references 20 to 22 and 28, only where there is a Duplicate System, a CEEC shall be performed unless a CEEC has been performed before on any unaffected:

part of duplicated CVA Metering Equipment e.g. only main CTs are changed but check CTs have had a CEEC done; or

CT/VT multicore e.g. main CT/VT multicore is changed but check CT/VT multicore has had a CEEC done; or
wiring for duplicated CVA Metering Equipment e.g. only wiring from the main Meter test block to the main Meter is changed but the check Meter has had a CEEC done; or
components for duplicated CVA Metering Equipment e.g. only components were replaced in the main Meter but the check Meter has had a CEEC done.

13. For reference 29 a CEEC shall be performed for a non-duplicate system unless a CEEC has been done before and any backup battery in the Meter or Outstation has not failed during power supply interruption; and for a duplicate system unless a CEEC has been done before on (any) unaffected Outstation and any backup battery in the affected Meter or Outstation has not failed during power supply interruption.

CEEC Techniques

The preferred technique for a CEEC, wherever possible, is for the Registrant to compare the HH readings provided by the CDCA against readings from an independent measurement source from the Settlement measurement transformers, e.g. independent transducers used as part of a Substation Control System (SCS), or a Supervisory Control and Data Acquisition (SCADA) system, or from protection CTs or ammeter readings, all provided that the transducer/transformer ratios have been confirmed through testing.

Where the preferred technique (option 1 above) is not practically possible, the Registrant can compare the HH readings provided by the CDCA against the expected consumption or generation based on Plant rated capacity and operational load at the time.

CEEC CDCA Thresholds

The threshold for a CEEC to be initiated by the CDCA is when the metered data being recorded for the relevant Outstation channel, for the relevant MSSID, reaches the level agreed with the Registrant.

Note: The Registrant may determine the threshold to be a percentage of rated capacity of the circuit or the percentage of the Outstation channel Maximum defined in the BSCP20/4.3 form.

CEEC Limits of Error

The threshold for CEEC to be passed using technique 1 is for the HH readings provided by the CDCA to be within +/- 10% of the readings from the independent measurement source.

The threshold for CEEC to be passed using technique 2 is for the HH readings provided by the CDCA to be within +/- 10% of the expected consumption or generation based on Plant rated capacity and operational load at the time.

Timescales

1. For new Metering CVA Systems, or new circuits added to existing systems, the commissioning and Proving Tests shall be carried out before the Effective From Date, in accordance with the timescales laid down in this BSCP and BSCP20.

2. For all other work on the CVA Metering Equipment the commissioning and Proving Tests should be carried out as soon as reasonably practicable, considering the requirement for accurate data in the Settlements system.

3. Where a Commissioning End to End Check is required, this shall be carried out with the timescales laid down in this BSCP.

1 For the avoidance of doubt, the CVA MOA shall submit the Proving Test form to the CDCA where a simple dial up is required (i.e. when reprogramming an Outstation at system level. See Ref 14 of Section 5.2.6).
