Change Proposal CP1196 (Changes to incorporate Central Management Systems in Unmetered Supplies arrangements), formalised the use of a Central Management System (CMS) in conjunction with an Equivalent Meter (EM). The relevant CMS 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; and
Application of default data by the MA.

This Test Specification covers the CMS tests that are required to gain approval for use of a CMS, and the test evidence that should be provided to the BSCCo to demonstrate compliance with the requirements and responsibilities as per BSCP520.

1.2 Approval Process

All new CMS are required by BSCP520 to be approved by the Panel or its delegated authority, the Supplier Volume Allocation Group (SVG). The initial expression of an intention to apply for approval of the CMS is made to BSCCo. The applicant will need to appoint a CMS Test Agent (a Meter Administrator) approved by the BSCCo to witness the tests specified in this document and prepare a test evidence report in conjunction with the CMS Test Agent .The approval process is managed by the Unmetered Supply User Group (UMSUG) who will review the test evidence report against the requirements of BSCP520. The UMSUG then makes a recommendation to the SVG regarding approval of the CMS.

This Test Specification aims to provide guidance to applicants by summarising the CMS requirements (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 is gained by running the specified tests in the presence of the CMS Test Agent; and the provision of a test evidence report by a CMS Manufacturer (supported by the CMS Test Agent) to the UMSUG and SVG. Once approved, the details of the new CMS will be added to an Approved Central Management System List maintained by BSCCo, and published on the BSC Website.

2. Understanding CMS Terminology

2.1 What is the difference between a Central Management System and a measured Central Management System (mCMS)?

As described in the introduction, Central Management Systems were first approved in 2008. Initially they were used to control lighting apparatus, latterly mCMS was introduced for equipment such as EV charging using measured feedback. In this document all the testing requirements apply equally to lighting CMS and measured mCMS unless specifically stated otherwise.

2.2 What are Unmetered Supplies under the BSC?

An Unmetered Supply (UMS) means a supply of electricity to a particular inventory of equipment in respect of which a Licensed Distribution System Operator (LDSO) has issued an Unmetered Supply Certificate. For example, this equipment could be any electrical equipment that draws a current and is connected to the Distribution Network without a meter recording its energy consumption, e.g. streetlights, traffic signals, zebra crossings, telecoms, etc.

2.3 What is the Unmetered Supplies Operator (UMSO)?

The UMSO is part of the LDSO also known as the Distribution Business or Network Operator (DNO). The UMSO is responsible for looking after all the Unmetered Supplies on its network and agrees with the Customer what equipment is suitable for treatment as an Unmetered Supply. Any equipment connected on an unmetered basis must be included in a detailed inventory supplied to the UMSO from the Customer’s asset database.

2.4 What is a detailed inventory?

As part of the agreement to provide Unmetered Supplies, Customers are required to submit an inventory to the UMSO that lists all of the equipment consuming energy. The format of an inventory can be found in the Operational Information Document published on the BSC Website. When equipment is CMS controlled the detailed inventory is summarised by the UMSO in a control file and supplied to the Meter Administrator to use in the HH energy calculations.

2.5 What is a Meter Administrator (MA)?

A Meter Administrator is a party undertaking a qualified Market Role for the processing of data for Unmetered Supplies. The MA is responsible for providing Half-Hourly (HH) consumption data into Settlement. This is the consumption of a particular Customer in kWh, for each half hour of every day. The Customer’s Supplier will appoint the MA in the industry’s registration system for Settlement purposes.

2.6 What is a CMS Test Agent?

A Meter Administrator approved to carry out the tests detailed in this test specification.

2.7 What are Charge Codes?

A Charge Code is simply a 13 digit number which represents a specific type of UMS equipment. It is used by UMSOs and MAs to look up the power value (known as circuit watts) associated with the equipment and calculate consumption. The percentage figures used in an Event Log are the percentage of the circuit watts allocated to the Charge Code. More information about Charge Codes and Switch Regime can be found on the BSC website (Charge Codes and Switch Regimes) and in the Operational Information Document.

2.8 What is a CMS Controller Charge Code?

A CMS Controller Charge Code is used to report the energy consumed by the CMS Control. Control Charge Codes follow the same approval process as other equipment connected on an unmetered basis and are reported in the customer’s detailed inventory. The Control Charge Code will have a circuit watt rating that reflects the power used by the control.

Some CMS can report the energy used by the control in the event log as a percentage of the Charge Code circuit watts for the controlled equipment. For example a CMS may be controlling a 50 watt lamp with a CMS control that consumes 1 watt continuously. For part of the night the lamp dims to 40 watts. The following percentage power levels will be reported in the Event Log against the CMS Unit Reference;

Night at full power 102.00
Night at dimmed power 72.00
Day (lamp off) 2.00

Where the CMS reports the control power in the Event Log, an application must be made for a Control Charge Code with a circuit watt rating of zero.

2.9 What are Switch Regimes?

Switch Regimes are three character alphanumeric codes that allow the operating hours for equipment to be determined. This information together with the power information obtained from the Charge Code allows consumption (kWh) to be calculated. The Switch Regime is a component of the detailed inventory submitted by the Customer to the UMSO. This is then used by the MA in the energy calculations.

The CMS Switch Regimes are;

990 – mCMS - EV charging
998 - CMS Controlled - Continuous Burning – Takes a permanent supply over 24 hours per day, which can be at different power levels.
999 - CMS Controlled - Switched Equipment – Supply is taken overnight, again can be at various power levels.

2.10 What is an Equivalent Meter (EM)?

An EM is the software used by the MA to calculate the Half-Hourly (HH) consumption data for Settlement.

2.11 What is a Sub-Meter?

A Sub-meter is a construct within the EM software that allows inventories of UMS data to be subdivided by customer, region or type of apparatus. For example; a customer that operates across two distribution regions would require a sub-meter identifier (id) for each region. Equally, two customers operating in the same distribution region would each require a sub-meter id to identify to which customer each set of inventory data pertains. A sub-meter could also be used to separate different types of apparatus. For example, a customer could have three sub-meters; one for CMS operated Highway Lighting, another for non-CMS operated Traffic signals, and another for mCMS EV charging Note that the mCMS sub-meter must be traded using a separate MPAN.

Each piece of apparatus (CMS Unit Reference) needs to be assigned Sub-Meter ID (used in the Event Log) and associated with the customer who is responsible for the unmetered supply. Test evidence must be provided explaining how this is achieved within the CMS. If a customer has apparatus in multiple distribution regions then a sub-meter ID is required for each region.

2.12 What is a CMS Unit Reference?

The CMS Unit Reference is a 12-digit alphanumeric field that acts as a unique identifier of the equipment under CMS control and to which the Charge Code and Switch Regime pertains. It is a requirement that the corresponding CMS Unit References are recorded in both the CMS and the Customer’s asset database. This is best achieved by using the Customer’s Asset ID, suitably “padded” to 12-digts if necessary. Using the Asset ID rather than the Control ID allows faulty controls to be replaced, without a change to the CMS Unit Reference and Control File. The Meter Administrator is obliged to issue a monthly exception list detailing CMS Unit References that appear in the customer’s control file that do not appear in the Event Logs output from the CMS. There are restrictions on the characters that can be used in the CMS Unit Reference, for example they cannot start with “H” or “T”. Full details are in BSCP520.

2.13 What is a Control File?

A control file is a list of all the equipment controlled by the CMS, listed by CMS Unit Reference and Charge Code. The UMSO creates the Control File using the detailed inventory supplied by the Customer that lists all the Customer’s unmetered equipment. The Control File is supplied to the MA as part of a data flow that is used by the MA in the energy calculations for the CMS sub-meter

2.14 What is an Event Log?

The Event Log is a file per Sub-Meter produced by the CMS that details the operational switching times and power levels for each unit and is made available to the MA daily. The log shall include the CMS Unit Reference, the time and date at which the load was switched and the power level expressed as a percentage of the full circuit watts of the Charge Code for the equipment. Each entry for a CMS Unit Reference in the Event Log for a day must have a unique time value expressed as HHMMSS. The format of the Event Log is specified in BSCP520.

2.15 What is Event Log Version control?

Each Event Log has a three digit version number in both its header record and file name. Version ‘001’ is the file produced each day and should contain records for each CMS Unit reference associated with the Sub-Meter Id. If any additional information becomes available for units after production of the Version ‘001’ Event Log (e.g. following a communication failure) on a subsequent day then a revised Event Log is required for those CMS Unit References where the data has changed.

The Version number for this Event Log should be incremented by ‘1’ (e.g. ‘002’) every time revised data becomes available.

The revised Event Log only requires events for CMS Unit references where the data has changed but must contain all events for those CMS Unit Reference for the day to which the Event Log pertains.

Each time revised data is obtained for CMS Unit References relating to a sub-meter an updated version of the Event Log is required.

For the avoidance of doubt, this means that a Version ‘002’ may be produced for one CMS Unit Reference for which data has been recovered and then followed by Version ‘003’ for another CMS unit reference if the data is recovered after production of Version ‘002’ (and so on for further updates). All the final versions of an Event Log for that day must be made available to the MA.

2.16 How is percentage power reported in an Event Log?

Equipment approved for connection on an unmetered basis is allocated a Charge Code as described earlier. The percentage power figure reported in an unmetered is the percentage of the circuit watts allocated to the Charge Code for the equipment under control by the CMS. For example a 100 watt lamp dimmed to a 66 watt power requirement, would have a power percentage of 075.00 reported in the Event Log.

An electric vehicle charging point controlled by mCMS has a single Charge Code with a circuit watt rating of 1,000 watts. If a charging point was providing a supply of say 5,000 watts, the power percentage reported in the Event Log would be 500.00.

3 Test Approach, Environment and Data Requirements

The CMS 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 CMS Test Agent 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).

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 interface between the CMS and the Customer’s asset database;
The recording of operational switching times and power levels in line with the CMS instructions processed;
Provision of the necessary volume and performance test evidence, to provide assurance that the CMS can meet operational timescales;
The technical details of the measurement device to be used;
The generation and making available of Operational Event Logs in the specified format that when processed by an EM will allocate energy accurately to the half hourly period when it was used; and

Testing in line with the scenarios detailed below (Scenarios in 4.1 below apply to lighting CMS, scenarios in 4.2 apply to mCMS).Test Scenarios for Central Management Systems used to control lighting

4.1 Test Scenarios for Central Management Systems used to control lighting

4.1.1 Scenario 1 – Switch Regime 999

Scenario 1 covers an unmetered supply, (CMS Unit Reference) with a switch regime of 999 for switched operation in the hours of darkness. The test coverage will encompass dimming in half hour increments as specified in the table below. The Unmetered Supply should be switched on and off by the CMS control.

Event	Time On/Off	% Full Power (Circuit Watts)	Duration
1	On by lux level or by programmed event	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	Off by lux level or by programmed event.	0%	Off

4.1.2 Scenario 2 – Switch Regime 998

Scenario 2 covers an unmetered supply (CMS Unit Reference) with a switch regime of 998 for an unswitched supply (continuous operation). The unmetered supply should be running at full load and the test must demonstrate that the device is already on, even though the full power instruction 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

In the circumstance that the CMS under test is unable to process the number of events in a 24 hour period, the scenarios will be agreed between the applicant and the CMS Test Agent and explained in the test evidence report

4.1.3 Scenario 3 – Control Failure for Multiple CMS Unit References

The applicant should simulate control failures where the CMS System has not communicated with a number of CMS controls and is unable to record and report the power level for the unmetered equipment being switched by those controls.

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.

4.1.4 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 4.3). The revised data is reported by issuing an incremental Event Log.

The incremental Event Log should cover:

Previously unknown data; and
Data which has been amended.

Note; The incremental Event Log must be a complete set of data for each control for the day including any previously reported valid data.

4.2 Test Scenarios for measured Central Management Systems

4.2.1 Scenario 1 – On and Off test

To start with the Apparatus should be in an off state, then connected and drawing a steady load for over an hour. It should then be disconnected before midnight, the events should be stored within the mCMS and an Event Log produced that demonstrates the on/off switching times and the percentage power across the duration of the events. The duration between the connection and dis-connection event should be at least one hour.

This test is designed to check that the Event Log will report percentages of power correctly timed to enable accurate energy consumption calculations allocated to the correct half-hour settlement period by the Equivalent Meter.

4.2.2 Scenario 2 – Two Events with Disconnection in Between

This scenario involves two events where the Apparatus is disconnected in between.

The Apparatus should be in an off state to start with, then connected and draw a steady load for at least a half hour. It should then be disconnected and stay off for an hour, before being reconnected and drawing a load for a further half hour. Finally it should be disconnected before midnight. As with the previous test this should result in an Event Log that enables correct energy consumption calculations allocated to the relevant half-hour settlement periods by the Equivalent Meter.

If the Apparatus has a configurable load, a scenario with variable load will be agreed with the CMS Test Agent. The duration of between the connection and dis-connection events should be at least one hour with a minimum of 1 hour between both events.

NB Scenario 2 should be repeated and used as the communications failure model in Scenario 6.

4.2.3 Scenario 3 – No Connection, No Consumption

The Apparatus should not be connected for an entire day. The applicant must demonstrate that when no Apparatus is connected a zero percentage event is produced in the Event Log.

4.2.4 Scenario 4 – Connection, No Consumption

The Apparatus should be connected for an entire day but not consuming power. The applicant must demonstrate that when the Apparatus is connected but consuming zero power, that a zero event is produced in the Event Log.

Note; If the CMS reports energy consumed by the control, the percentage power reported in the Event Log must be for the control only.

4.2.5 Scenario 5 – Consumption Over Midnight

In this scenario the Apparatus is connected and consuming power before midnight and continues to consumer power over the midnight boundary into the next day. The applicant must demonstrate that the Apparatus is still connected at midnight and records the correct event data, even though the consumption occurred the previous day. This test will require two Event Logs spanning the two consecutive days.

4.2.6 Scenario 6 – Communications Failure

The applicant must demonstrate that an accurate Event Log is maintained if there is a communications failure during part or all of the day. This test scenario is a repeat of Scenario 2 with a communications failure simulated where the measured mCMS is unable to record and report power levels recorded during the entirety of the second event.

This test is designed to confirm that only the first consumption event (before the communications failure) is included in the initial Event Log. Once communications have been restored, a subsequent Event Log should be produced showing both consumption periods for the test day.

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.

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). Note that Test Groups 1-7 & 11-12 apply to Lighting CMS and Test Groups 1-5, 8-10 & 11-12 apply to mCMS.

It should be noted that the Test Group Summary provides a guideline only. It is the CMS Test Agent’s responsibility to perform the appropriate tests in order to demonstrate compliance with all relevant system requirements.

The CMS Test Agent will use the Test Checklist to monitor compliance of each requirement.
