Change Proposal CP1196 (Changes to incorporate Central Management Systems in Unmetered Supplies arrangements), formalised the use of a Central Management System (CMS) as part of the overall Equivalent Meter (EM), with the relevant CMS and Meter Administrator (MA) system, functional requirements and responsibilities being set out in BSCP520: Unmetered Supplies Registered in SMRS. CP1196 was implemented on 26 February 2008.

BSCP520 includes functional requirements and responsibilities that cover:

CMS data storage;
Provision of data to the MA and Unmetered Supplies Operator (UMSO);
Data validation and exception handling by the MA;
Application of default data by the MA; and
Provision of data to the Half Hourly Data Collector (HHDC).

This Test Specification covers the CMS and MA System tests that are required to be performed by an applicant, wishing to gain approval for use of a CMS as part of the overall EM, and the test evidence that should be provided to the accredited test agent, currently BSCCo, to demonstrate compliance with the requirements and responsibilities as per BSCP520.

1.2 Approval Process

All new EMs are required by BSCP520 to be approved by the Panel or its delegated authority, the Supplier Volume Allocation Group (SVG). As part of this process, the initial stages of which are managed by the Unmetered Supply User Group (UMSUG), EMs are tested against the requirements of an EM specification in BSCP520 to ensure they are fit for purpose. The UMSUG then makes a recommendation to the SVG as to whether the EM should be approved for use.

A new testing and approval process has been introduced for EMs comprising a CMS. Under this approach, an applicant would commission an accredited test agent, currently BSCCo, who would evaluate the hardware and software against the EM requirements specified in BSCP520.

This Test Specification aims to provide guidance to applicants by summarising the EM requirements as specified in BSCP520 in the Requirements Test Checklist (Section 5), along with the associated testing (Section 6) that is necessary in order to demonstrate compliance.

Approval would be demonstrated by the provision of test evidence gained in the process of running the specified tests to the UMSUG and SVG. Once approved, the details of the new EM would be added to an Approved Equivalent Meters List maintained by BSCCo, published on the BSC Website.

1.3 Assumptions

The following assumptions have been made:

New MAs are required to undergo Qualification in accordance with BSCP537: Qualification Process for SVA Parties, SVA Party Agents and CVA MOAs, before operating in the market and before undergoing Central Management System EM approval;
If an existing MA chooses to make use of a CMS-based EM, the changes required to the participant’s systems and processes may trigger a requirement for re-qualification. The MA will determine whether they need to re-qualify in this circumstance. BSCCo can provide guidance on this matter where required;
The CMS may be operated by the MA or the Customer; however the MA retains the overall Settlement responsibility for the quality of the data submitted by the Customer via the CMS and the MA System; and
The CMS EM applicant will make available the relationship between the CMS functionality and power consumption at the supply terminals to the unmetered supply, to the accredited test agent, currently BSCCo. For e.g. the ratio of the lamp dimming percentage level to power consumption percentage level is 1:1. Approval of Charging Codes and associated power levels is obtained through UMSUG.

2. Test Approach

The CMS and MA system functional requirements and responsibilities (as per BSCP520) have been mapped to System Requirement Test Checklists (Section 5). These Checklists will be used by the accredited test agent, currently BSCCo, to ensure that the applicant has demonstrated compliance with all CMS and MA system requirements listed in BSCP520.

Each test requirement has been given a test reference number, which can be traced back where applicable, to the relevant requirement in BSCP520. Test References have been grouped into Test Groups with a summary of the tests and evidence required for each Test Group given in the Test Group Summary (Section 6).

The Test Group Summary (Section 6) has been provided as a guideline only. It is the applicant’s responsibility to ensure that the tests run show compliance with each requirement listed in the System Requirements Test Checklists (Section 5), and that the test evidence has been collected in a clear and precise manner (Section 7).

It is expected that the accredited test agent will witness the execution of the tests run by the applicant at the applicant’s premises.

It should be noted that functionality may differ slightly where the CMS and the MA systems are combined into a single application. However, overall functional requirements remain the same. The Test Group Summary (Section 6) details where functionality may differ.

3.Test Environment and Data Requirements

It is the applicant’s responsibility to provide the necessary test environments and data required to demonstrate compliance as per BSCP520, and to meet the requirements of all the key test scenarios given below (Section 4) and those in the Test Group Summary (Section 6).

Where the MA System is being tested in isolation it will be the applicant’s responsibility to secure or create the operational event logs or operational event log data that meet the appropriate scenario requirements.

4. Key Test Scenarios for Central Management systems

This section contains a high level summary of the key test scenarios included in the Test Group Summary (Section 6). This section does not contain an exhaustive list of all scenarios tested. The applicant is advised to analyse the testing requirements based on all scenarios listed in the Test Group Summary (Section 6).

The key CMS test scenarios shall include, but will not be limited to, the following:

Data security measures;
Synchronisation to Universal Time Clock (UTC);
The recording of Inventory and Equipment control information;
The issuing of CMS instructions for Scenarios 1 to 4 detailed below;
The recording of operation switching times and power levels in line with the CMS instructions processed;
The generation and making available of Operational Event logs in the specified format; and
Provision of the necessary volume and performance test evidence, so as to provide assurance that the CMS can meet operational timescales.

4.1 Scenario 1 – Switch Regime 999

Scenario 1 covers an unmetered supply, (CMS Unit Reference) with a switch regime of 999 (dusk to dawn). The test coverage will encompass dimming in half hour increments as specified in the table below. The unmetered supply should be automatically turned on at dusk and off at dawn.

Event	Time On/Off	% Full Power (Circuit Watts)	Duration
1	At Dusk (automatic)	100%	30 min
2	After 30 min	75 %	For 90 min
3	After 120 min	50 %	For 60 min
4	After 60 min	75%	For 120 min
5	After 120 min	100%	Till Dawn
6	At Dawn (automatic)	0%	Off

Where a CMS does not support dimming, but only on/off switching, the applicant will be expected to demonstrate only those events that meet the CMS functionality being tested. Scenario 1 would therefore be adapted as follows:

Event	Time On/Off	% Full Power (Circuit Watts)	Duration
1	At Dusk (automatic)	100%	For 180 min
2	After 180 min	0%	For 60 min
3	After 240 min	100%	For 60 min
4	After 300 min	0%	For 60 min
5	After 360 min	100%	Till Dawn
6	At Dawn (automatic)	0%	Off

4.2 Scenario 2 – Switch Regime 998

Scenario 2 covers an unmetered supply (CMS Unit Reference) with a switch regime of 998 (continuous burning). The unmetered supply should be running at full load and must demonstrate that the device is already on, even though the instruction full power; will have been given (a few days ago) in the past and is being recorded as such.

Event	Time On/Off	% Full Power (Circuit Watts)	Duration
1	Continuous burning	100%	Continuous

Event

Time On/Off

% Full Power

(Circuit Watts)

Duration

Continuous burning

100%

Continuous

It should be noted that the full power indicated above refers to the instruction made via the CMS Application and may not necessary equate to a percentage of actual power. The CMS applicant should report the relationship between CMS functionality and power consumption at the supply terminals to the unmetered supply, to the accredited test agent prior to testing. For example, the ratio of the lamp dimming percentage level to power consumption percentage level is 1:1. Approval of Charging Codes and associated power levels is obtained through UMSUG.

In the circumstance that the CMS under approval is unable to process the number of events in a 24 hour period, the scenarios will be agreed between the applicant and the accredited test agent, currently BSCCo.

Where dimming is associated with continuous burning, Switch Regime 999 will be used.

4.3 Scenario 3 – Control Failure for Multiple CMS Unit References

The applicant should reproduce a control failure where the CMS System is unable to record and report the power level set for multiple unmetered supplies.

The coverage required is:

unmetered supply for a single Settlement Day with a Switch Regime of 999;
unmetered supply for a single Settlement Day with a Switch Regime of 998;
unmetered supply for a range of Settlement Days with a Switch Regime of 999; and
unmetered supply for a range of Settlement Days with a Switch Regime of 998.

The unmetered supply CMS Unit Reference should be recorded on the CMS database and included in an operational event log. The failure may be noted by use of an information flag.

4.4 Scenario 4 – Revised Data after Control Failure (following day)

The applicant should demonstrate that data can be revised the next day for a previous control failure (Scenario 3). The revised data is reported either by issuing a refresh or an incremental operational event log for separate MA and CMS Systems, or if applicable, transferring the revised operational event data where the MA and CMS Systems are integrated.

The Refresh or Incremental Flow should cover:

Previously unknown data; and
Data which has been amended.

5. Requirements Test Checklist

This section provides a checklist of CMS and MA System requirements. The applicant is expected to comply with these system requirements for approval as a Central Management System Equivalent Meter.

Where applicable each requirement has been allocated the appropriate BSCP520 reference.

Test references have been grouped into Test Groups with a summary of the tests and evidence required for each Test Group given in the Test Group Summary (Section 6). It should be noted that the Test Group Summary provides a guideline only. It is the applicant’s responsibility to perform the appropriate tests in order to demonstrate compliance with all relevant system requirements.

Where the CMS and MA Systems are combined into a single application, all requirements shall apply unless otherwise stated in the Test Group Summary.

The certified test agent, currently BSCCo, will use the Test Checklist to monitor compliance of each requirement.
