1 Introduction

1.1 Purpose and Scope of the Procedure

The purpose of this Balancing and Settlement Code Procedure (BSCP) is to set out the processes for use by the agents appointed by the Asset Metering Virtual Lead Party (AMVLP) for all Asset Metering Systems registered with the Supplier Volume Allocation Agent (SVAA):

For the Half Hourly Data Collector (HHDC) and, where appointed in accordance with BSCP602, the Asset Metering Half Hourly Data Collector (AMHHDC) and to carry out the work for data collection (including data retrieval and data processing); and
For Supplier Volume Allocation (SVA) Meter Operator Agent (SVA MOA) or, where appointed in accordance with BSCP602, the Asset Metering Meter Operator Agent (AMMOA) and to carry out the work for meter operations (including, appointment changes, market data activities, connections, disconnections, reconfiguration or changes and where required proving (of Asset Metering Systems)).

For Asset Metering Systems, each Metering System is assigned a unique Asset Metering System Identifier (AMSID). This is for Asset Metering Systems with Asset Metering Equipment.

This BSCP describes the key interfaces and timetables for sending appropriate Asset Metering System data to/from the associated HHDC, associated AMHHDC, associated AMMOA, and associated SVA MOA on behalf of the associated AMVLP. In this BSCP, the “associated” agent is the agent for the relevant Asset Metering System for the time being appointed by the associated AMVLP. It also describes the key interfaces and timetables for the HHDC sending appropriate Asset Metering Systems data values to the SVAA

In this BSCP, any reference to “Meter Technical Details” means all the relevant information about Asset Metering Equipment required by the appropriate Data Collector, AMVLP or AMMOA/ SVA MOA) to carry out their duties. For the avoidance of doubt this includes, but is not limited to, the D0268 (Half Hourly Meter Technical Details) item listed in Data Interface flows.

This BSCP contains guidance on the completion of an ‘Asset Metering Complex Site Supplementary Information Form’ for the D0268 ‘Half Hourly Meter Technical Details’ data flow where the Asset Metering System is deemed to be at a Complex Site. This is where a fixed multiplier is to be applied to metered data and is not used for Asset Differencing. Asset Differencing is the responsibility of the AMVLP and is completed at the time of registration.

1.2 Main Users of Procedure and their Responsibilities

This BSCP should be used by AMVLPs and their Agent(s) (including SVA MOAs, AMMOAs, HHDCs and AMHHDCs) and the SVA Agent (SVAA).

AMVLP Agents using this BSCP shall be appropriately Qualified in Asset Metering.

The SVA MOAs, AMMOAs, HHDCs and AMHHDCs shall perform the responsibilities and obligations set out in this BSCP for an Asset Metering System for all Settlement Days for which the SVA MOA or AMMOA, HHDC and, where applicable, AMHHDC is appointed by the AMVLP for Asset Metering Systems registered with the SVAA.

The HHDC and AMHHDC shall use Qualified systems and processes so approved in accordance with BSCP537 and the Self-Assessment Document in carrying out the collection of data from Asset Metering Equipment; and for the purposes of collecting data have protocols for every Asset Meter Type for which it is responsible for data retrieval.

Where the same Asset Metering Equipment is being utilised for the measurement of the Import and/or Export Energy for more than one AMSID at a site, the AMVLP shall ensure that the same SVA MOA or AMMOA, HHDC and/or AMHHDC is appointed for all the AMSIDs involved to comply with the requirements of the BSC.

In the case where the SVA MOA, AMMOA, HHDC or AMHHDC cannot complete the required processes in this BSCP, this shall be reported to the AMVLP and the AMVLP shall resolve as appropriate.

In Asset Metering, the SVAA will be managing the registration of Assets and creation and issuing of related AMSIDs.

The HHDC’s and AMHHDC’s systems shall be set in accordance with Co-ordinated Universal Time (UTC) at least once every day.

On change of HHDC and / or AMHHDC, the HHDC and / or AMHHDC shall retain responsibility for data collected for all Settlement Days that they were appointed by the AMVLP for an Asset Metering System with the SVAA.

For each Asset Metering System the AMHHDC is appointed to, the AMHHDC shall send Asset Metering System Half Hourly Metered Data to the HHDC in kWh and in clocktime.

For each Asset Metering System the HHDC is appointed to, the HHDC shall send Asset Metering System Half Hourly Metered Data to the SVAA in kWh and in clocktime.

Where the HHDC has not received data in sufficient time to enable it to fulfil its obligations as HHDC, it shall request from the AMVLP or its agent that the data that has not been received be supplied forthwith.

The HHDC and, where appointed, the AMHHDC, shall prepare and maintain plans that will enable the AMVLP’s obligations under the Code to continue to be met notwithstanding the expiry or termination of the HHDC’s, or AMHHDC’s appointment as the HHDC or AMHHDC. The plans, which the HHDC, or AMHHDC, undertakes to implement on any such expiry or termination, will include the transfer of data and other information to an incoming HHDC or AMHHDC appointed by the AMVLP in accordance with section 2.1.4, 2.1.5, 2.1.6, 2.1.7, 2.1.8, 2.1.9, 2.1.10, 2.1.11 and 2.1.12 of this BSCP.

On expiry or termination of the HHDC’s, or AMHHDC’s, appointment as HHDC, or AMHHDC, in respect of an Asset Metering System the outgoing HHDC, or AMHHDC, shall continue to retain data and support the Trading Disputes process, as specified in Appendix 3.12, for all Settlement Days they were appointed by the associated AMVLP with the SVAA.

The HHDC and AMHHDC shall maintain and use records (as updated from time to time) of the Meter Technical Details (MTD), including energisation status received from the SVA MOA or AMMOA for each meter and communication system comprising each Asset Metering System for which it is responsible, together with access and site location details in respect of all such Asset Metering Systems.

The HHDC’s and AMHHDC’s system shall be capable of receiving, processing and transmitting all required data accurately and within the timescales agreed by the Panel and AMVLPs, and shall be capable of supporting metered data (processed and unprocessed) and associated standing data for all Asset Metering AMSIDs for which the HHDC and AMHHDC is appointed (with allowance for growth) for the retention periods specified.

The HHDC must only provide AMVLPs with data relating to AMSIDs against which the AMVLPs are contracted with the HHDC.

The AMHHDC must only provide HHDCs with data relating to AMSIDs against which the AMHHDCs and the HHDCs are contracted with the AMVLP.

3 APPENDICES

3.1 Validate Meter Data for Asset Metering Systems

Where the HHDC dials the Asset Meter directly it is responsible for these validation checks. Where the AMHHDC dials the Asset Meter it is responsible for these validation checks.

Unless the HHDC or AMHHDC is informed by the SVA MOA or AMMOA that the retrieved data is incorrect, the HHDC or AMHHDC shall accept Meter Period Value data collected from the Asset Meter for validation processing.

The HHDC and AMHHDC shall record all occurrences where data entering Settlements has been changed following instruction from the AMVLP.

The HHDC and AMHHDC shall retain the original reading value along with any alarms recorded in the Asset Meter, the reason for failure where the value is invalid and the reason for accepting data previously flagged as suspect.

The data retrieval process shall include the following checks; however in the case where data is received from the Outstation automatically step 3.1.3 ‘Outstation Time’ shall be performed at least every 20 calendar days by interrogation only.

3.1.1 Asset Meter Id (Device Id)

When the Asset Meter is interrogated by the HHDC or AMHHDC (as applicable), or when data is received from the Asset Meter the ‘electronic serial number’ of the Asset Meter is compared with that expected. If they differ then no data is collected (or processed further) and the failure is investigated in accordance with section 2.3.3.

3.1.2 Asset Meter Number of Channels

When the Asset Meter is interrogated by the HHDC or AMHHDC (as applicable), or when data is received from the Asset Meter automatically, the number of channels of the Asset Meter is compared with that expected. If they differ then no data is collected (or processed further) and the failure is investigated in accordance with section 2.3.3.

3.1.3 Asset Meter Time

When the Asset Meter is interrogated, by the HHDC or AMHHDC (as applicable) the time of the Asset Meter is compared with that expected. If they differ by more than 20 seconds and less than 15 minutes then the outstation time is corrected by the data collection system. If the time differs by more than 15 minutes then the problem is resolved in accordance with section 2.3.3.

3.1.4 Alarms

When the Asset Meter is interrogated by the HHDC or AMHHDC (as applicable), or when data is received from the Asset Meter automatically, the individual alarms shall be investigated if flagged. Half Hourly Integral Outstation Meters will have alarms but other Asset Meters may not have alarm flag functionality.

Each alarm shall be investigated in accordance with section 2.3.3.

3.1.5 Cumulative/Total Consumption Comparison

When the Asset Meter is interrogated by the HHDC or AMHHDC (as applicable), or when data is received from the Asset Meter automatically, and where the Asset Meter provides an electronic cumulative reading of the prime register equivalent to the total consumption of the Asset Meter at that point in time. Using these readings, the following checks will be performed at least every seven days (i.e. on a daily or weekly basis or as agreed by the AMVLP and HHDC, or AMHHDC).

i) The difference between the cumulative readings shall be calculated to ensure that the HH Metered Data used in Settlements sums to the Asset Meter advance for the same interval⁵⁰, i.e. that the difference between cumulative readings and the sum of the Metered Period Data for the same date(s) and time(s) is within a suitable tolerance. It is recommended that the level of the tolerance should be set to take into account the period over which the check was performed. The recommended maximum levels are ±0.7% where the check is carried out on a weekly basis and ±5% where the check is carried out on a daily basis.

Specifically:

Σ(pulses * pulse multiplier) for all Asset Meter periods in the time interval = (Asset Meter advance * Asset Meter multiplier) for the time interval.

The calculation below outlines how the discrepancy should be calculated when performing tolerance checks.

Discrepancy = (\frac{\sum HHE - MA}{MA}) \times 100 %

Where:

∑HHE is the sum of HH Energy volumes in kWh; and MA is the corresponding Asset Meter Advance, i.e.

MA = M₂ – M₁

Where:

M2 is the cumulative reading (in kWh) returned from the last time that the Asset Meter was interrogated; and M1 is the cumulative reading (in kWh) returned from the previous time that the Asset Meter was interrogated or data was received automatically over the same time period as the sum of HH period energy.

ii) Where a main and check Asset Meter is fitted, the main and check Asset Meter advances are compared for any discrepancy between the two values in excess of 1.5 times the class accuracy requirements for the individual Asset Meters at full load, as defined in the CoP 11 for the relevant Asset Metering Type.

Allowances shall be made for low load discrepancies. If the discrepancy is unacceptable it shall be investigated in accordance with section 2.3.3.

3.1.6 Maximum Permissible Energy by Metering System Code of Practice Eleven

During validation by the HHDC or AMHHDC (as applicable), where the energy recorded exceeds the permissible allowed, in accordance with column 4 in the table below, for one or more given Settlement Period, the HHDC or AMHHDC (as applicable) will notify the AMVLP.

CoP11 Asset Metering Type	Max. kW	Max kWh / Half Hour	Permissible Allowed: kWh per Half Hour
1	675,000	337,500	400,000
2	100,000	50,000	50,000
3	10,000	5,000	5,000
4	1,000	500	600
5	100	50	50

Following instruction from the AMVLP, the AMHHDC or HHDC (as applicable) will enter the actual data into Settlements or the HHDC or AMHHDC (as applicable) will replace the actual data with estimated data and enter this into Settlements.

Where however the AMVLP does not provide instructions to the HHDC or AMHHDC (as applicable), the HHDC or AMHHDC (as applicable) will apply the following rules, either:

use actual consumption data if the energy has exceeded the permissible allowed by no more than 20%; or
use estimated consumption data, rather than the actual consumption data if the energy exceeded the permissible allowed by more than 20%.

Note that:

Asset Metering Types 1, 2 and 3 are circuit capacity based and it is assumed that the Maximum Demand will not exceed the maximum kWh / Half Hour value.

Asset Metering Types 4 and 5 are demand based and may occasionally exceed the maximum kWh / Half Hour value.

3.1.7 Main/Check Comparison

Where main and check Asset Meters are installed the HHDC or AMHHDC (as applicable), ensure that the Metered Data recorded by each Asset Meter is compared for each circuit. Allowance shall be made for low load discrepancies. Any discrepancy between the two values in excess of 1.5 times the accuracy requirements of that prescribed for the individual Asset Meters at full load, as defined in the CoP 11 for the relevant Asset Metering Type, shall be investigated in accordance with section 2.3.3.

3.1.8 Site Checks of Asset Metering System - Site Visit Report

The following checks shall be carried out by the HHDC or AMHHDC (as applicable) on the Asset Metering System when visiting a Site:

1.	Any evidence of suspected faults to the Asset Metering System including phase/fuse failure.
2.	Any evidence of damage to metering and associated equipment.
3.	Any evidence of tampering of any sort with the Asset Metering System or associated equipment, particularly seals.
4.	Any evidence of supply being taken when the Asset Meters are de-energised.

NB The Local Interrogation Unit (IU) or Hand Held Unit (HHU) should be set to ensure agreement with the UTC clock at least every week.

For Asset Metering Types 1, 2, 3 and 4 sites with polyphase Asset Metering Systems should be visited at least annually, Asset Metering Type 5 and single phase at least at two yearly intervals to perform the checks described above. Site visits made for other reasons may be used to carry out these checks.

Any problems are investigated in accordance with section 2.3.3 and a report is issued. The HHDC or AMHHDC (as applicable) shall ensure that where a site visit was not possible, the reasons are explained sufficiently such that appropriate action can be taken to improve the chances of securing a successful site visit.

3.1.9 Reporting

Ensure that all cases of suspected Asset Metering Systems faults are investigated in accordance with section 2.3.3 and are reported to the AMVLP and SVA MOA or AMMOA, as appropriate.

Ensure that the original metered value (where obtained) and alarm(s), together with the reason for the changes to that value are retained.

3.2 Data Estimation for Asset Metering Systems

Where an AMHHDC has been appointed, they will perform the estimation and the HHDC will not be required to do so. The HHDC will perform the estimation only where they communicate with the Asset Meter directly.

Active Energy data will be estimated for Asset Import and Asset Export Metering using one of the following data estimation methods in the order of precedence specified below. Data will be flagged appropriately as indicated below.

No estimation is required for Reactive Energy.

When the HHDC or AMHHDC (as applicable) receives information from the SVA MOA or AMMOA, site reports or other sources concerning metered data which has been or will be collected and processed, the Meter Period Value data shall be estimated in accordance with this BSCP where the HHDC or AMHHDC (as applicable) believes the data to be in error. The HHDC or AMHHDC (as applicable) shall inform the AMVLP where an error might affect a different AMVLP or data affects the Final Reconciliation Volume Allocation Run.

The HHDC or AMHHDC (as applicable) shall retain any original value collected, whether such value is processed before or after receipt of any details of invalid data from the SVA MOA or AMMOA, site reports or other source, and any alarms set up at the Asset Meter.

Details of all data estimations and the rationale behind using the chosen method must be recorded for Audit purposes.

The HHDC or AMHHDC (as applicable) will notify the relevant AMVLP of the data estimation method in accordance with 3.2.3 below.

HHDCs and AMMHDCs should consider local information, where available, when carrying out estimations. Where no instruction or additional information has been received from the AMVLP missing data should be estimated to zero in techniques d. and e. in 3.2.1 and 3.2.2.

Having estimated data using one of the methods below, a report is to be produced in accordance with 3.2.3 below.

If a data estimation has been completed and submitted to the SVAA and actual ‘A’ flag data OR information leading to more accurate estimated data becomes available, this revised data shall be notified to the AMVLP and submitted to the SVAA for use in the next Volume Allocation Run.

Where a MAR has failed, in accordance with Appendix 3.8, due to a data estimation being included in the period of reconciliation, that period of data estimation shall be re-estimated.

Data Flag	Description
A	Actual data (read automatically or manually)
C	Long day / short day indicator
E	Estimated data

Any Asset Metering System data received with Data Flag “C” will be processed as if it had contained Data Flag “E”.

3.4 Reasons for Requesting a Metering System Investigation.

For an Asset Metering System, a D0001 Request Metering System Investigation, or equivalent P flow, is issued where the HHDC, AMHHDC or AMVLP identifies or is made aware of a problem that requires an Asset Metering System investigation by the SVA MOA or AMMOA to resolve. Possible reasons include but are not limited to:

• The HHDC, or AMHHDC, suspects invalid MTD on the D0268 Half Hourly Meter Technical Details;

• The HHDC, or AMHHDC, has reason to suspect data retrieved from an Asset Metering System;

• Data retrieved from an Asset Metering System failed validation and/or Meter Advance Reconciliation;

• Consumption data is detected on an Asset Metering System registered as de-energised;

• The HHDC, or AMHHDC, is unable to resolve an issue in retrieving data from an Asset Metering System;

• Data required for a proving test cannot be obtained;

• Consumption data is flagged with an alarm; and/or

• At the request of the AMVLP.

3.5 Key Asset Meter Technical Details.

Subject to 2.5, below is a list of key fields of Meter Technical Details (MTD) that will cause the Asset Metering System to be proved if any, or all, of them are changed whilst the Asset Metering System, is energised:

Outstation Id;
Asset Meter Id (serial number);
Outstation number of channels;
Measurement Quantity Id;
Asset Meter multiplier;
Pulse multiplier;
CT and / or VT Ratios; and
Access to Asset Metering Equipment at Password level 3.

Where any, or all of the above are changed whilst an Asset Metering System, is de-energised, a proving test shall be initiated as soon as that Asset Metering System becomes energised and completed in the timescales set out in Appendix 3.6.5.

3.6 Proving of Half Hourly Metering Systems.

For Outstations which can only have a pulse multiplier of 1 as identified on the Elexon website (compliance and protocol approval list), a proving test is not required unless the Outstation is subject to a Complex Site arrangement or is separate from the Asset Meter.

3.6.1 Reasons for a Proving Test.

Subject to 2.5 for Asset Metering Systems, a proving test shall be carried out on both main and check Asset Metering Systems and shall be carried out in any of the following circumstances:

Following a change of HHDC, or AMHHDC, appointment but only in the event that the MTD was manually intervened;
Following a change of SVA MOA, or AMMOA, appointment but only in the event that the MTD was manually intervened;
Following a concurrent Change of AMVLP and HHDC, or AMHHDC, but only in the event that the MTD was manually intervened;
When an Asset Metering System is reconfigured / replaced;
When there is a key field change (refer to Appendix 3.5);
Where there has been a key field change (refer to Appendix 3.5) whilst a site has been de-energised and the Asset Metering System becomes energised; or
Where a feeder is energised for the first time.

3.6.2 Methods of Proving.

For Asset Metering Systems, the SVA MOA or AMMOA shall decide which technique from the list below is to be used to collect data in conjunction with the HHDC and AMHHDC.

The techniques the SVA MOA or AMMOA can use to record HH data for a proving test are:

Record the HH Metered Data reading while on site; or
Use the Asset Meter manufacturer’s software to download the HH Metered Data; or
Use software which has a relevant protocol approval in accordance with BSCP601 ‘Metering Protocol Approval and Compliance Testing’ to download the HH Metered Data.

The HHDC or AMHHDC collects the HH Settlement Period requested and where an AMHHDC collects the HH Settlement Period requested they should send it on to the HHDC. The HHDC then sends this raw HH Metered Data to the SVA MOA or AMMOA for comparison. If unable to collect Metered Data for Settlement Period requested, the HHDC should send alternative Settlement Period Half Hourly Metered Data.

3.6.3 Comparison of Data.

After a proving test on an Asset Metering System has been undertaken by any of the methods selected above, the SVA MOA or AMMOA then compares the data received from the HHDC to determine a successful or a failed proving test.

3.6.4 Reporting.

The SVA MOA or AMMOA shall report both successful and non-successful proving tests to relevant parties.

3.6.5 Proving Test / Re-Test Timescales.

Proving Test Timescales

A proving test on an Asset Metering System may be undertaken prior to the appointment of the HHDC or AMMHDC and / or SVA MOA or AMMOA so long as there is agreement between the AMVLP, SVA MOA or AMMOA (as applicable), HHDC and AMHHDC (if applicable) and the customer.

The timescale for carrying out the proving test shall vary depending on the Asset Metering Type in Code of Practice Eleven that the Asset Metering System is assigned to.

The maximum timescale between the initiation of a proving test for an Asset Metering System as a result of the circumstances in 3.6.1 and the successful completion of the proving test by the SVA MOA, or AMMOA, (by sending the D0214 Confirmation of Proving Tests) to the HHDC and, if applicable, AMHHDC is listed below for each Asset Metering Type.

Re-Test Timescales

Where the proving test has failed, the SVA MOA or AMMOA shall initiate a re-test and the SVA MOA or AMMOA, and HHDC and AMHHDC (if applicable) should ensure wherever possible that the timescale is the same as for the original proving test.

Timescales – Asset Metering Systems

CoP11 Asset Metering Type	WDs to Complete Proving Test^⁵²	WDs to Complete Re-Test	Total
One	5	5	10
Two	5	5	10
Three	10	10	20
Four	15	15	30
Five	15	15	30

In the event that timescales are exceeded and the proving test is not completed, the process shall proceed to completion and an audit trail will be maintained by AMVLP Agents in order to explain the delay.

3.6.6 Failed Proving Test.

If a proving test has failed, then the Metered Data collected will be flagged as estimated i.e. ‘E’ flagged. This collected HH Metered Data will continue to be flagged as estimated until a successful proving test is completed.

The SVA MOA or AMMOA, and HHDC, and AMHHDC if applicable shall complete the re-test as soon as possible after failure of the original proving test.

For an Asset Metering Type Three related Asset Metering System, the timescale for completing the proving test may extend beyond the Initial Volume Allocation Run, in which case the rules for Asset Metering Type Four related Asset Metering System’s shall apply as far as data estimation is concerned.

3.6.7 Non-Completion of Proving Test.

If a proving test is not completed so that proved data can enter Settlements by the due timescales, the actual retrieved HH Metered Data shall be used for Settlements and shall be ‘A’ flagged until a proving test has been completed. Once a proving test has been completed, the data will be flagged as either estimated or actual i.e. ‘A’ flagged depending on whether or not there was a successful proving test.

3.6.8 Proving Test Exemptions

If a proving test is not required as set out in section 2.5 then the actual retrieved HH Metered Data shall be used for Settlements and shall be ‘A’ flagged.

3.7 Inbound Data Comparison Check

For an Asset Metering System, where data is to be sent automatically from the Asset Meter to the HHDC or AMHHDC instation for use in Settlement and following a successful Proving Test, the HHDC or AMHHDC shall perform a comparison check between one half hour of data received via the inbound method of communication and the equivalent half hour of data received by interrogating the Asset Meter. The results of the comparison test shall be recorded for audit purposes and any inconsistency shall be investigated in accordance with section 2.3.3. In the event of any inconsistency the HHDC or AMHHDC shall revert to interrogation of the Asset Meter. In addition, the HHDC or AMHHDC shall revert to interrogation of the Asset Meter, at any time, on request by the Registrant of the Asset Metering System.

3.8 Meter Advance Reconciliation – Asset Metering Systems.

A Meter Advance Reconciliation (MAR) is the reconciliation of the advance on the Asset Meter register between two specific date(s) and time(s) compared with the summation of the relevant Settlement Period data used in Settlement over the same date(s) and time(s). This activity is performed by the HHDC or the AMHHDC (as applicable).

Care should be exercised where the Asset Meter register reading does not align with the end of a Settlement Period, and this should be taken into consideration in the reconciliation.

3.8.1 Asset Meters that record cumulative energy with either separate Outstations or integral Outstations which do not provide an electronic cumulative reading of the prime Asset Meter register equivalent to the total consumption or production of the Asset Meter as part of its normal function.

The HHDC or AMMHDC (as applicable) shall perform a MAR:

a) at least once every three months for Asset Meters over 100kW; or

b) at least once every twelve months for Asset Meters below 100kW.

Where a change of HHDC or AMHHDC (as applicable) has occurred, the new HHDC or AMHHDC (as applicable) shall perform a MAR within the first six months of the appointment for Asset Meters below 100kW using the last physical Asset Meter register reading taken on site by a Qualified AMVLP Agent or read remotely by the AMVLP or a Qualified AMVLP Agent provided by the old HHDC or AMHHDC (as applicable).

Asset Meter readings recorded from the physical Asset Meter register during a site visit by a Qualified AMVLP Agent or read remotely by the AMVLP or a Qualified AMVLP Agent may be used for the purpose of the MAR under a) or b) above.

Using the Asset Meter register readings taken during any site visit or remote reading, the following checks shall be performed:

i) Ensure that the HH Metered Data between two different date(s) and time(s), as used in Settlements, sums to the Asset Meter advance from site readings of the prime Asset Meter registers for the same date(s) and time(s), i.e. that the difference between successive cumulative Asset Meter register readings and the total of the Metered Period Data for the same time interval, is within a tolerance of ±0.1%.

Specifically:

Σ(pulses * pulse multiplier) for all Asset Meter periods in the time interval = (Asset Meter advance * Asset Meter Multiplier) for the time interval.

The calculation below outlines how the discrepancy should be calculated when performing tolerance checks.

Discrepancy = (\frac{\sum HHE - MA}{MA}) \times 100 %

Where:

∑HHE is the sum of HH Energy volumes in kWh; and MA is the corresponding Asset Meter Advance, i.e.

MA = M₂ – M₁

Where:

M2 is the Asset Meter register reading (in kWh) taken during the recent site visit; and M1 is the Asset Meter register reading (in kWh) taken during the site visit prior to the recent site visit (e.g. 3 months prior for a 100kW+ Asset Metering System)

If after making allowance for the readings not being taken at the end of the preceding Settlement Period (and other factors such as estimates made during the period of the MAR calculation) the above checks fail, then the failure shall be investigated in accordance with section 2.3.3.

The D0008 ‘Meter Advance Reconciliation Report’ shall be produced for the AMVLP on a monthly basis. This will include:

MAR confirmation;
MAR failure; and
MAR overdue,

for all Asset Metering Systems for which a MAR has been, or should have been, carried out during the preceding month.

3.8.2 Asset Meters with integral Outstations which provide an electronic cumulative reading of the prime Asset Meter register equivalent to the total consumption or production of the Asset Meter as part of its normal function.

A MAR is not obligatory providing that the Cumulative / Total Consumption Comparison as described in Appendix 3.1.5 can be carried out. Where the Cumulative / Total Consumption Comparison validation cannot be carried out, a MAR shall be performed as described in 3.8.1.

3.8.3 De-energised Asset Meters

Routine MAR is not required for de-energised Asset Meters, on the basis that there is no advance to reconcile.

3.9 Guide to Asset Metering Complex Sites

‘Complex Site’ means; any site that requires an ‘Asset Metering Complex Site Supplementary Information Form’ to enable the HHDC to interpret the standing and dynamic Metered Data relating to Asset Metering Systems for Settlement purposes. This is to be provided to the HHDC or AMHHDC in addition to the D0268, ‘Half Hourly Meter Technical Details’.

Asset Differencing does not require an ‘Asset Metering Complex Site Supplementary Information Form’ and this is the responsibility of the AMVLP to arrange as part of the registration process.

There are two situations where an adjustment for losses can be made using an ‘Asset Metering Complex Site Supplementary Information Form’:

System Losses – Where the Asset Meter is subject to a Metering Dispensation and is not located at the Defined Metering at the Asset Point and an electrical loss factor has been applied to account for equipment and cabling between the Actual Metering at the Asset Point and the Defined Metering at the Asset Point; and

Inverter and Rectifier Losses – Where the location of the Asset Meter, where it is Asset Metering Type 5, is in such a place that it does not account for the losses of the inverter or rectifier.

Where the AMSID is 1234567890111 and the losses between the Actual Metering at the Asset Point and the Defined Metering at the Asset Point have been calculated as 2% the aggregation rule would be:

1234567890111 = 1234567890111 x 1.02

An adjustment for losses should be done for both the Import AMSID and the Export AMSID should the Asset Meter be configured to record both Asset Import and Asset Export.

Number of Import AMSIDs = 1

Number of Export AMSIDs = 0 or 1 (as applicable)

The primary electronic data flow between the SVA MOA or AMMOA and HHDC, and AMHHDC (if applicable) for Half Hourly Meter Technical Details is the D0268. Where this data flow alone is insufficient to accurately describe to the HHDC or AMHHDC how to apply a fixed multiplier to the various channels of data that should be utilised in Settlements the MTDs is supplemented with the ‘Asset Metering Complex Site Supplementary Information Form’. The HHDC or AMHHDC will run the aggregation rule specified in the ‘Asset Metering Complex Site Supplementary Information Form’ to apply the fixed multiplier.

The SVA MOA or AMMOA, should identify a Complex Site by providing an ‘Asset Metering Complex Site Supplementary Information Form’ in addition to the D0268 data flow to the HHDC, AMHHDC and AMVLP indicating in the D0268 data flow that the site is complex. The ‘Asset Metering Complex Site Supplementary Information Form’ shall be sent no later than, or preferably in advance of, the sending of the D0268 data flow. This action shall alert the HHDC to expect an ‘Asset Metering Complex Site Supplementary Information Form’ from the SVA MOA or AMMOA, containing details of how to configure the data collected by an HHDC, or AMHHDC, for Asset Metering Systems. The ‘Asset Metering Complex Site Supplementary Information Form’ should be sent electronically or by any other method agreed.

It is the responsibility of AMVLPs to manage and co-ordinate their Agents to achieve compliance and to intervene should any issues arise.

The AMVLP should identify to the SVA MOA, or AMMOA, which AMSIDs relate to the Import energy and which AMSIDs relate to the Export energy.

In some cases, a Complex Site for Asset Metering Systems shall meet the conditions required to apply for a Metering Dispensation as described in BSCP32 ‘Metering Dispensations’. Where Complex Sites use Asset Metering Systems that are not fully compliant with CoP 11, a Metering Dispensation should be applied for via BSCP32. Once a Metering Dispensation has been granted, the information shall be available for all future AMVLPs, so that they shall have the ability to understand the metering configuration at the Complex Site. As part of the dispensation application process, the AMVLP shall need to submit a simplified schematic diagram of the Complex Site connection arrangements and the proposed metering points, as required in BSCP32.

Form CoP11/Fa ‘Asset Metering Complex Site Supplementary Information Form’ provides a means for the SVA MOA or AMMOA to convey the information necessary for correct aggregation. CoP11/Fa shows the information needed to collect that data.

Where meter channel data is missing, incomplete or incorrect, the HHDC or AMHHDC (as applicable) should attempt to use the associated check data where a check Asset Meter is installed.
