1. Introduction

1.1 Purpose and Scope of the Procedure

This BSC Procedure (BSCP) defines the process of inspections of Supplier Volume Allocation (SVA) Half Hourly Metering Systems registered in a Supplier Meter Registration System2 (SMRS), Central Volume Allocation (CVA) Metering Systems registered in the Central Meter Registration Service (CMRS) and Asset Metering System registered with the Supplier Volume Allocation Agent (SVAA).

It describes the key interfaces and timetable responsibilities for the role of the Technical Assurance Agent (TAA) and interested parties in the inspection of Metering Systems or Asset Metering Systems. The primary aim of Technical Assurance is to monitor Registrants’ and Party Agents’ compliance with their obligations as defined in the Balancing and Settlement Code (the Code) and Code Subsidiary Documents (CSDs) to ensure that the Active Energy Imported and/or Active Energy Exported through Boundary Points, System Connection Points and Defined Metering at the Asset Point is complete and accurate.

The secondary aim of Technical Assurance is to assess the overall health of all the SVA and CVA Half Hourly Metering System population. The TAA will provide an indication of the overall health of these Metering Systems in the TAA Annual Report.

This BSCP will only apply to SVA MOAs, with respect to SVA Metering Systems, until such time that the SVA MOA Technical Assurance Transitional Period detailed in Section J 7.1.4 - 7.1.6 has concluded after which assurance of SVA MOA activity may transfer to the REC.

1.2 Risk Based Performance Assurance Framework

Performance Assurance Techniques (PAT) will be applied to Performance Assurance Parties (PAP) based on the net significance of the applicable Settlement Risk and an assessment of the PAP’s contribution to the Settlement Risk.

Settlement Risks and their net significance are captured on the Risk Evaluation Register (RER). All the Settlement Risks identified are rated in terms of severity of impact and probability (including a weighting for the strength of controls).

The Settlement Risks are assigned PATs to mitigate those risks and these PATs are recorded in the Risk Operating Plan (ROP) against each Settlement Risk.

The RER and the ROP are produced for a Performance Assurance Operating Period in accordance with the Annual Performance Assurance Timetable and the agreed Risk Evaluation Methodology (REM), which details the processes used to identify and evaluate the Settlement Risks and assess their materiality.

At the end of a Performance Assurance Operating Period, the Performance Assurance Board (PAB) will prepare an Annual Performance Assurance Report for the Panel detailing the assurance that has been provided during the course of the period, the extent to which Settlement Risks have been mitigated, and BSCCo costs of providing that assurance.

Technical Assurance of Half Hourly Metering Systems for Settlement Purposes is a Performance Assurance Technique and will be deployed to a PAP in relation to relevant Settlement Risks.

1.9.2 Main Sample – CVA

The CDCA shall submit an electronic list of all Metering System IDs registered in the Central Meter Registration Service (CMRS), together with associated information to BSCCo. The lists shall be provided four times a year on dates agreed with BSCCo. The required information will be forwarded to the TAA to initiate the sample selection process.

The TAA will use reasonable endeavours to minimise the number of repeated audits when selecting the Metering Systems to be audited.

The TAA will select 10% more Metering System IDs than will be audited. The additional 10% will enable the TAA to categorise the Metering Systems and ensure that there is no bias towards any one Party, Metering Equipment type or sampling area. This initial sample will be sub-divided by Registrant and CVA MOA.

BSCCo will provide additional guidance for the selection of sampled audits.

On finalising the sample, the relevant Registrant will be notified of the Metering Systems to be audited.

1.9.3 Main Sample – SVA

This is the main sample selection process (excluding those detailed in 1.8.2) for SVA Metering Systems.

Each SMRA shall ensure that the details it holds are updated daily to a central online database, together with any associated information as specified in BSCP501 to the PAA via BSCCo. The required information will then be used by the TAA to initiate the sample selection process.

The TAA will use reasonable endeavours to minimise the number of repeated visits when selecting the Metering Systems to be audited.

The TAA will select 10% more Metering System IDs than will be audited. The additional 10% will enable the TAA to categorise the Metering Systems ensuring that there is no bias towards any one Party, Metering Equipment type or sampling area. This initial sample will be sub divided by GSP Group, Registrant and SVA MOA.

On finalising the sample, the relevant Registrant will be notified of the Metering Systems to be audited.

1.9.4 Main Sample – Asset Metering Systems

This is the main sample selection process (excluding those detailed in 1.8.2A) for Asset Metering Systems.

The SVAA shall submit an electronic list of all Asset Metering System IDs registered in the Asset Meter Registration Service (AMRS), together with associated information to BSCCo. The lists shall be provided four times a year on dates agreed with BSCCo. The required information will be forwarded to the TAA to initiate the sample selection process.

The TAA will use reasonable endeavours to minimise the number of repeated audits when selecting the Asset Metering Systems to be audited.

The TAA will select 10% more Asset Metering System IDs than will be audited. The additional 10% will enable the TAA to categorise the Asset Metering Systems and ensure that there is no bias towards any one Party, Asset Metering Equipment type or sampling area. This initial sample will be sub-divided by Registrant and SVA MOA and AMMOA.

BSCCo will provide additional guidance for the selection of sampled audits.

On finalising the sample, the relevant Registrant will be notified of the Asset Metering Systems to be audited.

1.10 Re-Inspections

Where a non-compliance has been identified and subsequently reported as rectified, it is possible that the Metering System, or Asset Metering System, will be re-inspected by the TAA to confirm compliance.

BSCCo will inform the TAA of the percentage of previously non-compliant Metering Systems, or Asset Metering Systems, which should be re-inspected. Re-inspections will be selected with consideration given to the category and number of non-compliances associated with the previous inspection.

The TAA will submit the proposed schedule of re-inspections to BSCCo for approval. Upon approval the TAA shall carry out a re-inspection to confirm compliance.

1.11 Targeted Audit

Where the PAB requires assurance about a particular Metering System or Asset Metering System, they may request a targeted audit to take place.

The PAB will use the following information when deciding to perform a targeted audit:

    • Previous non compliances;

    • Information provided by the BSC Auditor;

    • Technical Assurance of Performance Assurance Parties checks;

    • Line Loss Factor Audits;

    • Information from Parties;

    • Performance related issues;

    • Settlement error;

    • Information provided by its sub-committees; or

    • Information provided by the Panel.

This list is not exhaustive.

1.12 Metering System and Asset Metering System Inspection

On selection of an appropriate Metering System, or Asset Metering System, the TAA shall notify the relevant Registrant, MOA or AMMOA and LDSO (only for SVA and CVA Metering Systems) prior to the date of the intended Inspection Visit. The Registrant or a nominated representative will be invited to attend the Inspection Visit and shall make all reasonable endeavours to ensure access to all Metering Equipment, or Asset Metering Equipment, and for SVA and CVA Metering Systems will liaise with the LDSO or NETSO (if necessary) to arrange such access.

The Registrant shall be required to ensure that the MOA or AMMOA and for SVA and CVA Metering Systems the LDSO (mandatory attendance for High Voltage Metering Systems) or the NETSO (if necessary) will be in attendance and that the person attending the site is technically competent to discuss problems relating to any defects or non-compliances and able to agree the resolution of any defects or non-compliances. The person should be able to access all the relevant Metering Equipment, or Asset Metering Equipment, (where safe access is possible).

The Registrant shall notify the TAA (the Registrant may discharge this to the MOA or AMMOA), prior to the intended Inspection Visit that the MOA or AMMOA (and LDSO if applicable) will be in attendance. In addition the Registrant will inform the TAA of any other representatives that will be present at the Inspection Visit. Failure to do so will be reported to PAB at the discretion of BSCCo.

A MOA or AMMOA may appoint a competent third party who may attend on their behalf.

For SVA Metering Systems the appropriate LDSO shall arrange to gain independent access to the LDSO's equipment associated with the Metering System and the SVA MOA shall arrange for access to the Meter and associated Metering Equipment for which it is responsible. The LDSO shall accede to such a request within 10 working days of the request from the Registrant and / or SVA MOA.

For CVA Metering Systems the Registrant (or its nominated representative) shall provide access to the Metering Equipment during the Inspection Visit.

For Asset Metering Systems the Registrant (or its nominated representative) shall provide access to the Asset Metering Equipment during the Inspection Visit.

The TAA may, with the agreement of BSCCo, arrange for an urgent revisit (SVA and CVA Metering Systems, Asset Metering Systems) to be initiated. This will be at the expense of the Registrant if:

(a) The Registrant fails to arrange access on the agreed date and time or access cannot be obtained upon arrival by the TAA;

(b) The MOA or AMMOA fails to attend an Inspection Visit; or

(c) The LDSO or NETSO fails to attend an Inspection Visit (SVA and CVA Metering Systems only).

Any costs incurred by the MOA or AMMOA or LDSO or the NETSO as a result of its attendance at an Inspection Visit shall be met by themselves.

Where the TAA has gained access to the Metering System, or Asset Metering System, but has been unable to complete the Inspection Visit, a result of ‘incomplete Inspection Visit’ and the reason for non-completion will be recorded. These instances will be reported to PAB at the discretion of BSCCo.

Where the TAA has been unable to gain access to the Metering System, or Asset Metering System, a result of ‘no access’ and the reason for no access will be recorded. These instances will be reported to PAB at the discretion of BSCCo.

1.13 Desktop Audit

Desktop Audits shall be performed by the TAA as directed by the PAB as a Desktop Audit sample and as part of the main sample, specific sample or targeted audits.

On selection of a Metering System, or Asset Metering System to be audited via desktop, the TAA shall notify the relevant Registrant, MOA or AMMOA, HHDC/AMHHDC/CDCA, for SVA and CVA Metering Systems the LDSO and NETSO (as appropriate) prior to the date of the intended Desktop Audit. The TAA shall request the documents required to complete the Desktop Audit.

The Registrant shall be required to ensure that the MOA or AMMOA, HHDC/AMHHDC/CDCA, for SVA and CVA Metering Systems the LDSO and NETSO (as appropriate) provide the documents requested by the TAA to allow the Desktop Audit to be completed. Where the required documents are not received, the Metering System, or Asset Metering System, will be found non-compliant.

Where the TAA has been unable to complete a Desktop Audit a result of unresponsive Registrants, the Registrant will be found non-compliant. These instances will be reported to PAB at the discretion of BSCCo.

1.14.4 Half Hourly Metering System or Asset Metering System Functional Information

Failure to provide the above information to the TAA within the required timescales as defined in section 4 shall be classified as a non-compliance.

The TAA may request any additional information that is felt necessary and reasonable for any Metering System, or Asset Metering System, being audited. This additional information will also be provided by the Registrant in a reasonable timeframe prior to the Inspection Visit or Desktop Audit where possible.

Where appropriate, all information to be provided to the TAA regarding an Inspection visit or Desktop Audit should be provided via the software system used by the TAA.

1.15 Non-Compliance

The TAA shall raise a non-compliance if, after taking into account any Metering Dispensations:

(a) The requirements of the Code and CSDs; or in the case of SVA MOAs for SVA Metering Systems, the Retail Energy Code Metering Operations Schedule, are not being adhered to;

(b) The actual configurable Meter, or Asset Meter, parameters are not consistent with the Meter Technical Details recorded in Settlement systems as provided by the HHDC, AMHHDC or CDCA or AMVLP, or MOA or AMMOA prior to an Inspection Visit or Desktop Audit.

(c) The Registrant fails to commit to provide requested documentation and/or Consumption data, as outlined an Evidence Request for a Desktop Audit (Section 3.7.2).

The findings of an Inspection Visit will be recorded on an Inspection Schedule and presented to the MOA or AMMOA at the time of the Inspection Visit. Wherever possible any identified non-compliances shall be rectified by the MOA or AMMOA at the time of the visit.

The findings of a Desktop Audit will be recorded on a Desktop Audit Schedule and communicated to Registrants and relevant agents via the software system used by the TAA.

Categorisation of non-compliances

NC

A non-compliance has been identified through the Consumption Data Comparison Check that is deemed to be currently affecting the quality of data for Settlement purposes.

Category 1 Non Compliance

A non-compliance has been identified from an Inspection Visit, which is deemed to be currently affecting the quality of data for Settlement purposes

Category 2 Non Compliance

A non-compliance has been identified from an Inspection Visit, which is deemed to have the potential to affect the quality of data for Settlement purposes

Category A Non Compliance

A non-compliance has been identified from an Desktop Audit, which is deemed to be currently affecting, or has a high likelihood of affecting, the quality of data for Settlement purposes

Category B Non Compliance

A non-compliance has been identified from a Desktop Audit, which has been deemed to have a lower likelihood of affecting the quality of data for Settlement purposes, or for the non-provision of evidence

Observation

A non-compliance has been identified which is deemed neither to affect nor to have the potential to affect the quality of data for Settlement purposes

On completion of an Inspection Visit or Desktop Audit, the TAA shall issue notices of compliance or non-compliance to the Registrant, MOA or AMMOA, HHDC, AMHHDC, LDSO and the NETSO as appropriate and where a non-compliance has been determined, the TAA shall provide the Registrant with the details of the non-compliance.

Where a non-compliance has been determined the Registrant shall be responsible for progressing the rectification of the non-compliance and must submit a rectification plan to the TAA in a timely manner and must ensure that the action to resolve the non-compliance is performed in a timely manner. The Registrant will be required to take all reasonable steps to ensure that the party that can take direct action does so, and that the Registrant pursues that party to the extent necessary. Where BSCCo deems it necessary for SVA and CVA Metering Systems, non-compliances not rectified by the Registrant will be reported to the PAB who will decide on further action in accordance with BSCP538, Error and Failure Resolution.

1.16 Queries & Appeals

Where a non-compliance has been identified, this may be queried by:

          • The Registrant responsible for that Metering System; or

          • The relevant MOA, AMMOA, HHDC, AMHHDC, LDSO or the NETSO.

The non-compliance can be queried as follows:

1. Initially to the TAA who will review the query and provide a response.

2. If unsuccessful in 1, the raiser may pursue the query with BSCCo, or withdraw the query. If the query is not withdrawn, BSCCo will review the query and provide a response to the raiser.

3. If unsuccessful in 2, the raiser may raise an appeal with BSCCo and the Panel, or withdraw the query. The Panel may choose to delegate this responsibility to the PAB.

The Registrant (or MOA, AMMOA, HHDC, AMHHDC, LDSO or the NETSO on behalf of the Registrant) will be required to provide evidence in support of the queries and appeals if requested to do so by the Registrant and BSCCo.

1.17 Rectification Action

The Registrant (or MOA, AMMOA, LDSO, HHDC, AMHHDC or the NETSO on behalf of the Registrant) will rectify the non-compliance or provide a rectification plan (BSCP27/05), which will detail the appropriate milestones and actions to be taken in order to achieve rectification within the timescales required and set out in section 4.

1.18 Post Rectification Action

Where a Registrant is required to perform testing as per CoP 4, ‘Code of Practice for the Calibration, Testing and Commissioning Requirements of Metering Equipment for Settlement Purposes’, following the rectification of a non-compliance, the PAA or BSCCo or TAA shall have the option to attend and/or request details of the tests performed.

The costs associated with the rectification of a non-compliance and any subsequent testing shall be borne by the responsible Party.

1.19 Reporting

BSCCo may report the findings of an Inspection Visit or Desktop Audit and any outstanding non-compliances to the PAB.

4 Appendices

4.1 Description of Inspection Checks

This appendix describes the tests & checks that may be required to be carried out by the TAA as part of an Inspection Visit, as determined by the PAB. This is not an exhaustive list.

4.1.1 Measurement Transformer Specification (where appropriate)

Where possible check the:

(a) Ratio, class, rated burden and polarity from the labels physically attached to the measurement transformers and/or the identification plates attached to switchgear or other enclosures containing measurement transformers (in practice this will not always be practical for safety reasons). And

(b) Test records/certificates detailing specific measured errors held by the LDSO, or equipment owner, associated with the measurement transformers on site or from agreed Generic CT/VT certificates (SVA) in the case of CTs and VTs.

4.1.2 Meter Technical Details

Check to ensure that the actual Meter Technical Details conform to those recorded in Settlement Systems using:

(a) Information provided by the CDCA (CVA), Registrant (SVA/Asset Metering Systems) or Party Agent in accordance with Section 1.14 of this BSCP, including any measurement transformer error offsets & commissioning details.

(b) Information supplied to the CDCA, HHDC, AMHHDC and MOA or AMMOA.

(This may require a remote/local interrogation of data for comparison purposes).

4.1.3 Accuracy

The following checks should be performed to verify the overall accuracy requirements of the Metering System or Asset Metering System:

(a) Measurement transformers relate to test certificates provided;

(b) Meter - test certificate calibration details are in accordance with requirements in CoP Four, or for Asset Meters in accordance with requirements in CoP Eleven;

(c) Metering Equipment, or Asset Metering Equipment installed is in accordance with the relevant CoP and where required the Main and Check Meters, or Asset Meters are correctly identified.

The overall accuracy is to be determined by the TAA and shall be within the requirements of the applicable CoP.

4.1.4 Correct Energy Measurement Check

To verify that the Metering System, or Asset Metering System, is recording the correct amount of energy, checks shall be carried out that compare the primary load with that being recorded by the Metering System, or Asset Metering System. However, due to the possible restrictive physical location of the primary conductors and Plant at an installation, access may be limited. Where this is the case, other suitable methods may be used to determine correct measurement.

For SVA and Asset Metering sites installations can be divided up into the following three categories:

(a) LV whole current;

(b) LV, CT operated;

(c) HV, CT & VT operated.

Sites that fall into categories (a) and (b) will prove to be the most accessible for prevailing load checks. Sites in category (c) may be more difficult to access, but it is often possible to use a clip-on ammeter around the current transformer cables where access to switchgear is restricted.

Note: When all preferred methods of checking the prevailing load fails, other suitable engineering methods may be adopted to establish correct measurement.

Methods of establishing primary load (in order of preference):

1. The demand (derived from independently measured primary values) shall be compared to the Meter’s, or Asset Meter’s, instantaneous demand reading for the same period; or

2. The demand (derived from independently measured secondary values where the primary/secondary ratios can be established) shall be compared to the Meter’s, or Asset Meter’s, demand reading for the same period; or

3. Where appropriate an alternative measurement device shall be used for comparison with that of the Settlement Meter, or Asset Meter’s; or

4. The MOA or AMMOA shall provide the TAA with appropriate commissioning records. The TAA is required to establish that these details sufficiently verify that the Meter, or Asset Meter, has been proven to be operating correctly during commissioning; or

5. In the event that none of the above is possible, the TAA will notify BSCCo giving the reasons. (This recognises that if 1 to 4 are not possible additional checks do not add value.)

4.1.5 Consumption Data Comparison Check

The TAA shall compare the metered energy data for one half hour recorded at the time of the Inspection Visit with the consumption data held by the HHDC (in the case of Asset Metering Systems this could also be held by the AMHHDC acting as the data retriever) or CDCA for that same half-hour period. If the values differ by more than agreed tolerances the TAA will issue a non-compliance. This check can take place on site or off site at the discretion of the TAA and either method forms part of the Inspection Visit.

The tolerances will be agreed from time to time by the PAB.

In order to obtain and verify stored Meter, or Asset Meter, data values that are eventually transferred to the HHDC (in the case of Asset Metering Systems this could also be held by the AMHHDC acting as the data retriever) or CDCA, it will be necessary to use a Hand Held Unit running relevant approved Hand Held Unit protocol to download data from the Meter, Asset Meter or Outstation. This process will also provide engineering units (e.g. kW half hours) or raw pulses and some standing data. Once the pulse multiplier or constant (e.g. a multiplication constant of 0.5 is required to convert kW/MW half hour values to kWh/MWh half hour values) is applied the kWh/MWh value can be compared with the consumption data held by the CDCA or HHDC or AMHHDC (if applicable) and the Meter’s, or Asset Meter’s (displayed8) cumulative advance over the same half hour period. The kWh/MWh value will also be compared with the measured value obtained from the Correct Energy Measurement Check.

This Consumption Data Comparison Check shall take the following format:

1. Compare the Meter, or Asset Meter, Technical Details provided by both the HHDC or CDCA or AMHHDC and MOA or AMMOA with that observed on-site. Consideration should also be given to Commissioning and historic proving test information.

2. Take a reading (for the dominant Active Energy flow direction at the time) of the cumulative register on the Meter’s or Asset Meter’s display8 at the beginning and end of the same half hour period that is to be downloaded from the Meter’s, or Asset Meter’s Outstation and requested from the CDCA or HHDC or AMHHDC as applicable.

3. Using the Meter, or Asset Meter, Register Multiplier, calculate the true Meter, or Asset Meter, register half hour advance for that half hour period.

This cumulative Meter, or Asset Meter, register half hour advance shall also be used to confirm the findings from the Correct Energy Measurement Check where, ideally, the readings for that check were taken within the same half hour period and the load (or generation) was relatively constant during that period. The TAA shall use its discretion, bearing in mind the predictability of the load (or generation), where the readings weren’t taken in the same half hour period.

4. Download a half hour reading from the Meter’s, or Asset Meter’s, Outstation and convert the value (raw pulses or engineering units) into a kWh half hour reading (for SVA registered Metering Systems and Asset Metering Systems) or

5. Request the current actual consumption data held by the CDCA or HHDC or AMHHDC for the same half hour period and compare the energy recorded by the Settlement Meter, or Asset Meter (cumulative Meter register half hour advance) and its associated Outstation(s) (half hour value) with the energy value held in the CDCA or HHDC or AMHHDC systems which will be submitted to Settlement.

One Active Energy channel will be requested unless a non-compliance is identified.

4.1.6 Code of Practice Compliance

All points to be checked as specified in the appropriate CoP.

4.1.7 Quality of Installation

All points to be checked as specified in the applicable CoP, including:

(a) Labelling of equipment.

(b) General standard of installation i.e. good working practice.

4.1.8 BSCCo will perform an estimated metered error calculation, to be included in the Annual Report to the PAB, to provide an indication of the impact of errors on Settlement, in particular the impact that category 1 non-compliances may be having, this will mean that BSCCo will need to record the estimated materiality for all category 1 non-compliances.

This estimated net error calculation shall take the following format:

(a) Calculate the percentage error.

(b) Using the percentage error, calculate what would have been in Settlement if the error had not occurred.

(c) Calculate the difference between what should have been in Settlement and what is actually in Settlement to provide a materiality in MWh.

4.3 Provision of Measurement Transformer Certificates for Metering Equipment and Asset Metering Equipment

4.3.1 Objective

BSC Parties require assurance that Metering Equipment and Asset Metering Equipment operates within the accuracy limits defined in the appropriate CoP. As part of the process of establishing this assurance, evidence is required of the measurement transformer errors associated with the Metering System. This section explains the process involved in achieving such assurance.

4.3.2 Ownership

In the context of this BSCP, Equipment Owner is defined as the owner of the measurement transformers which form part of the Metering System or Asset Metering System.

4.3.3 Responsibilities

The MOA or AMMOA responsibilities are as stated in the Code and Code Subsidiary Documents and for SVA MOAs, with regards to SVA Metering Systems, the Retail Energy Code Metering Operations Schedule.

The Equipment Owners responsibilities regarding the provision of measurement transformer certificates and co-operation with the MOA or AMMOA, are stated in the Code and Code Subsidiary Documents and for SVA MOAs the Retail Energy Code Metering Operations Schedule.

The MOA or AMMOA should request the measurement transformer certificates from the Equipment Owner. The Equipment Owner should provide these certificates to MOA or AMMOA within the required timescales. Consistent failure to do so may lead to the Equipment Owner being requested to explain why to the PAB.

4.3.4 Procedures for CoP1, CoP2, S1 and S2

The MOA should obtain the necessary measurement transformer test certificates from the Equipment Owner. This should be provided within 10 WD of the request.

If the necessary test certificates are not immediately available, the Equipment Owner shall advise the MOA of that situation (within 10 WD of the request) and state what steps are being taken to obtain the test certificates associated with the measurement transformers for that circuit/Site.

If the Equipment Owner does not have the necessary test certificates readily available, the Equipment Owner should request copies of the original test certificates. Where these are obtained, they should then be supplied to the MOA as soon as possible after the request from the MOA.

If the required test certificates are not available, the Equipment Owner must either:

(a) Quote errors for a measurement transformer of similar characteristics, e.g. accuracy class, ratio, burden rating, manufacturer, type, age, etc; or

(b) Obtain measurement transformer errors by testing; or

(c) Replace the installed units by units with known errors at the earliest opportunity.

In either of (a) or (b) above, the Equipment Owner shall provide evidence to support the errors provided. This information shall be passed to the MOA within a further period of 10 WD of the errors being established.

The MOA will, as required, provide to the TAA the information supplied by the Equipment Owner.

4.3.5 Procedures for CoP3, CoP5, S3 and S5

The MOA should obtain the necessary measurement transformer error certificates from the Equipment Owner. This should be provided within 10 WD of the request9.

If the necessary error certificates are not readily available the Equipment Owner must provide the MOA, (still within the 10 WD of the request), with one of the following:

Copies of the original certificates

A generic certificate.

A generic certificate needs to be approved by the Panel. In order to approve a generic certificate, the Panel requires evidence that the statistical analysis method used is robust. The statistical analysis needs to be specific to ratio, make, rating, class and type.

When carrying out an audit the TAA will ask the MOA for the measurement transformer error certificates. The MOA will provide to the TAA, the information provided by the LDSO.

4.3.6 Procedures for CoP11 – Asset Metering System

The SVA MOA, or if applicable the AMVLP should obtain the necessary measurement transformer error certificates from the Equipment Owner. This should be provided within 10 WD of the request9.

If the necessary error certificates are not readily available the Equipment Owner must provide the SVA MOA, (still within the 10 WD of the request), with one of the following:

    • Copies of the original certificates; or

    • A generic certificate.

A generic certificate needs to be approved by the Panel. In order to approve a generic certificate, the Panel requires evidence that the statistical analysis method used is robust. The statistical analysis needs to be specific to ratio, make, rating, class and type.

When carrying out an audit the TAA will ask the SVA MOA for the measurement transformer error certificates. The SVA MOA, or AMVLP if applicable, will provide to the TAA, the information provided by the Equipment Owner.
