1. Introduction

1.1 Scope and Purpose of the Procedure

This BSC Procedure defines those activities which enable the Supplier Meter Registration Service (SMRS) to fulfil its functions, relating to the following:-

Provide Suppliers with information relating to their MSIDs.

Notify Suppliers of loss of Settlement liability for MSIDs previously allocated to them. Provide New Suppliers with the Metering System Registration Data related to their MSIDs.

In the case of ‘fringe’ supplies, the SMRA within whose service area the SVA Metering System falls, is responsible for providing the Registration Service.

Provide Half Hourly Data Aggregators with MSID information.

Provide HHDAs with Half Hourly SVA Metering System Registration Data.

Provide Non Half Hourly Data Aggregators with MSID information.

Provide NHHDAs with Non Half Hourly SVA Metering System Registration Data.

Receive and process Supplier data.

To update the SMRS database with information when the Supplier is the data source.

Bulk Change of Non Half Hourly Supplier Agent

Where there is to be a change in a NHH Supplier Agent (bulk change of agent) such that the number of SVA Metering Systems affected exceeds a threshold set by the BSC Panel, a bulk change of agent application will be submitted for approval in accordance with BSCP513. Following such approval, this BSC Procedure will be used to process the bulk change of agent, without adversely impacting the normal daily operations of the SMRA.

Receive and process Licensed Distribution System Operator data.

To update the SMRS database with information when the Licensed Distribution System Operator is the data source.

Receive, validate and process SVA Meter Operator Agent data.

To validate information when the SVA Meter Operator Agent is the source and update the SMRS database with valid information. To send a response to the SVA Meter Operator Agent to notify the outcome of the validation.

Receive and process Market Domain Data.

To update the SMRS database with information from the Market Domain Data source.

Enable Transfers of Registrations between SMRS and CMRS.

To facilitate the Transfers of Registrations of Third Party Generator / Exemptable Generating Plant between SMRS and CMRS and vice versa.

Enable new connections where the same Metering Equipment at an Exemptable Generating Plant is comprised in both an SVA Metering System and a CVA Metering System, where Export Active Energy is traded in CVA and Import Active Energy is traded in SVA.

To ensure that relevant information is passed between appropriate participants and certain checks are carried out in the CVA and SVA registration systems to facilitate this type of registration.

Record BSCCo Required Data

To record the BSCCo Required Data for every Settlement Day that the MSID is connected.

1.2 Main Users of Procedure and their Responsibilities

This BSC Procedure should be used in the main by the SMRSs.

However the following organisations will also require input to or output from the SMRS; the SVAA (as MDDM), Suppliers, Data Aggregators, Licensed Distribution System Operators, SVA Meter Operator Agents, BSCCo, Central Registration Agent and the Transfer Co-ordinator.

Each Licensed Distribution System Operator is required to provide a single SMRS. As there is no restriction on the number of Licensed Distribution System Operators that may operate within a single GSP Group, there may also be a number of different SMRSs operating within that same GSP Group.

1.3 SMRS Access Restrictions, Controls and Constraints

The SMRA shall only permit access to people whose job responsibilities include the operation, support or audit of the SMRS.

For the avoidance of doubt, the access restrictions relating to the SMRA’s commercial role only relate to the Code requirements and Code Required Data.

The SMRA shall implement and maintain at least the following controls:

• Unique MSIDs in order that the Settlement system can work;

• Validation checks to ensure that all mandatory data fields are present on registration, and data is input accurately;

• Controls to ensure that the LDSO disconnects the correct SVA Metering System within SMRS;

• Controls to ensure that standing data is complete, accurate and up-to-date (i.e. consistent with the most recent valid input), and that there have not been unauthorised (i.e. invalid) changes;

• Controls to ensure that SVA Metering Systems are allocated to the correct GSP Group;

• Controls to ensure that the data held by the SMRS remains confidential;

• Controls to ensure that information is distributed to only the correct Party and Party Agents;

• Controls over input, processing and output (as well as over data and communications) in order to ensure that the rules for valid data processing defined during system design (including those specified by the Code) are adhered to, and the data held and processed by the SMRS is accurate, complete, valid and not out of date; and

• Controls over the development and implementation of the SMRS (including the authorisation and co-ordination of transfers of data and programs) to ensure that:

- The system is tested prior to going live, with test plans and results documented;

- Systems documentation is provided in sufficient detail to support ongoing operational and future maintenance;

- Quality management is used;

- Migration of data onto the SMRS is conducted in a controlled manner, with data validity checks carried out;

- Users are adequately trained such that they are competent in the use of the system;

- Separate test and live environments are used; and

- A fully documented and repeatable system test model is used.

The SMRS shall be developed and operated in line with the following constraints:

• The SMRS shall allow entry of new Suppliers to the market and the exit of Suppliers from the market;

• The SMRA shall implement and maintain controls to ensure registration is made against the correct MSIDs (for the avoidance of doubt, MSIDs are allocated by the LDSO, who allocates the GSP Group for an SVA Metering System); and

• The SMRS shall enable the unambiguous identification of all SVA Metering Systems and their previous and current Suppliers together with dates of any changes.

1.4 Audit Trail and Auditor Access

The SMRA shall implement and maintain an audit trail which has at least the following characteristics:

• Data shall be traceable from the data held in SMRS to the source instruction and vice versa;

• Data shall be stored on magnetic or optical media in a consistent format;

• The SMRA shall record the effective date of changes in responsibilities;

• Movement of SVA Metering Systems between different SMRSs upon change of SVA Metering System’s LDSO shall be traceable;

• The SMRA shall be able to retrieve values of amended data in order to ensure that a full transaction history is available; and

• The data held on SMRS shall be maintained in order to ensure completeness, accuracy, and timeliness. The changes to data held require the following:

- That changes made shall be easily identifiable;

- The effective date for those changes made;

- The authoriser of the change and their authority; and

- For any manual changes, an explanation of why the change was made.

The SMRA shall ensure that the BSC Auditor has access at reasonable times and at reasonable notice to:

• Software, hardware or information held by the SMRA or its agents, where reasonably required by the BSC Auditor to fulfil its obligations under the Code;

• The relevant parts of the SMRA’s premises; and

• Relevant staff members of the SMRA, for a reasonable length of time in any one year.

1.5 Qualification

In providing the services specified in this BSCP, the SMRA shall use systems and processes so approved in accordance with BSCP537 that comply with the Code, BSC Procedures and PSL100.

1.6 Service Availability and Service Levels

On Working Days, the SMRA shall use reasonable endeavours to ensure that staff are available during Service Hours, defined as from 09:00 to 18:00.

The SMRA shall use reasonable endeavours to ensure that any planned outages are scheduled such that there is the minimum amount of disruption to the Service, and wherever practicable provide as much notice as possible to the relevant Data Aggregators and Suppliers.

In the event of an unplanned cessation of processing, the SMRA shall use reasonable endeavours to reinstate the service to meet its requirements under this BSCP as quickly as possible, and shall implement its disaster recovery procedures within 48 hours of the start of the cessation of processing.

Where agreed with the associated Supplier, the SMRA may provide additional services in support of a bulk change of agent outside of normal working hours, providing these additional services do not adversely impact its normal operational activities.

The SMRA shall provide BSCCo with information derived from its systems and processes so approved in accordance with BSCP537 in accordance with the SVA Data Catalogue, BSCP533 and its Appendices such that the SMRA can comply with the requirements of Appendix 4.7. All such communications shall be date-timestamped by the SMRA.

1.7 Use of the Procedure

This procedure should be referred to by the users to understand the responsibilities and role of the SMRA and the relationships between the SMRA, Licensed Distribution System Operator (LDSO), Suppliers, SVA MOAs, UMSO, SVAA and Data Aggregation agents.

Throughout this procedure, timetables reflect the number of Working Days (WD) within which an activity should be completed.

Although not shown in each interface timetable, there is an assumption that each communication successfully received at the SMRS gateway will be acknowledged by the Data Transfer Network. The acknowledgements sent will indicate the number of transactions received in each communication. In addition, SMRA will report to the originator, the number of files accepted and the number of files rejected (with reason codes) in accordance with the interface timetable.

The interface timetables in this BSCP show that any changes to registration data in SMRS shall be notified to the LDSO. Although not shown in each interface timetable, there is an assumption that where changes relate to an Unmetered Supply, the details of these changes shall also be notified to the UMSO by the LDSO.

In the case of non half hourly Supplier Agents, the SMRA will be informed via BSCP513 of any Supplier’s intention to initiate a change of agent where the number of Metering Systems affected exceeds the threshold set by the Panel. The SMRA will be required to confirm whether it can implement the proposed changes without adversely impacting other SMRS activities. Any bulk change of agent must therefore be initiated via BSCP513 before triggering the processes in this BSC Procedure.

The remaining sections in this document are:

Section 2 – Not used.

Section 3 - Interface and Timetable Information: this section defines each business process in detail. In addition, there, may be references to ‘D’ and ‘P’ dataflows in the ‘Information Required’ column.

Section 4 - Appendices: this section contains supporting information

The SVAA will be managing the Market Domain Data in addition to performing the Supplier Volume Allocation role, and therefore SVAA is the Market Domain Data Manager (MDDM).

1.8 Balancing and Settlement Code Provision

This BSC Procedure has been produced in accordance with the provisions of the Code. In the event of an inconsistency between the provisions of this BSC Procedure and the Code, the provisions of the Code shall prevail.

The requirements of SMRAs under the Code can be found in BSC Section J. An overview of these requirements is as follows:

The principal functions of an SMRA are to:

• Provide and operate a registration service in respect of those Boundary Points on the Distribution System(s) and Associated Distribution System(s) (if any) of such SMRA which are not registered in the Central Meter Registration Service;

• Provide data from such registration system to Parties, Party Agents and BSC Agents for the purposes of Settlement; and

• Provide BSCCo with data from such registration system for the purposes of monitoring in accordance with BSCP533.

4. Appendices

4.1 This page has intentionally been left blank

4.2 Erroneous Registrations

4.2.1 General principle

The “Old Supplier” should not dismiss his Agents (i.e. Data Collector, Data Aggregator and SVA Meter Operator Agent) until the “Old Supplier” has received confirmation from SMRA that there is a “New Supplier” in place.

4.2.2 Scope

This section considers erroneous Registrations which are agreed by both Suppliers as being made in error. Where there is a dispute, the Suppliers may either use the REC disputes process, or seek redress through legal proceedings.

4.2.3 Identification of Registration Error

The identification of Registration errors falls into two distinct “time slots”:

identification by either Supplier:

(a) within the objection period;

(b) after the objection period.

4.2.4 Rectification of Registration Error

Time slot (a): Old Supplier raises objection through SMRA. If the New Supplier identifies the error, then the New Supplier should contact the Old Supplier and request that the Old Supplier lodges an objection with SMRA. (Table 4.2.5)

Time slot (b): Old Supplier re-registers as soon as practicable. If the New Supplier identifies the error, then the New Supplier should contact the Old Supplier and request the Old Supplier to re-register. (Table 4.2.6)

4.3 Data Validation

The SMRS must validate all BSCCo Required Data submitted before accepting or rejecting the data.

Upon rejection of data, the SMRA shall set out all the reasons for rejection to the sending market participant.

The SMRA shall ensure that all data for SVA Metering Systems conform with the rules outlined in the following table.

Property

Non Half Hourly

Half Hourly

Profile Class

Valid Profile Class (as specified in MDD) required

Profile Class not required

Standard Settlement Configuration

Valid Standard Settlement Configuration (as specified in MDD) required

Standard Settlement Configuration not required

Data Aggregator Appointment

Data Aggregator required to be specified as non half hourly in MDD

Data Aggregator required to be specified as half hourly in MDD

Data Collector Appointment

Data Collector required to be specified as non half hourly in MDD

Data Collector required to be specified as half hourly in MDD

LLF Class Id

Valid LLF Class Id (as specified in MDD) required.

Valid LLF Class Id (as specified in MDD) required.

MOA Appointments for Unmetered Supplies

Unmetered Supply Operator to be specified (from a list of Unmetered Supply Operators in MDD), in place of the SVA MOA, in the SVA MOA field to ensure a valid Unmetered Supplies Operator is appointed.

Appropriate ‘Measurement Class’ has been recorded for Non Half Hourly Unmetered Supplies

Meter Administrator to be specified (from a list of Meter Administrators in MDD), in place of the SVA MOA, in the SVA MOA field to ensure a valid Meter Administrator is appointed.

Appropriate ‘Measurement Class’ has been recorded for Half Hourly Unmetered Supplies

Please note that during the registration process for Non Half Hourly or Half Hourly Unmetered Supplies, the MOA field containing the UMSO/MA MPID is dependent on the Measurement Class field of the registration flow. Therefore if a change is made to the Measurement Class, it should be accompanied by a change in the SVA MOA field (e.g. if the Measurement Class changes from Non Half Hourly UMS to Half Hourly Unmetered Supply, this should mean a change of agent e.g. UMSO to MA).

For any particular event, the SMRA shall apply one or more of the following validation criteria as appropriate:

• Data will only be accepted from the market participant that is the source of the data as defined in Section 3 of this document;

• Upon receipt of a change to the data within SMRS, SMRA shall validate that any of the following codes involved in the change are valid (in accordance with the Market Domain Data) on the effective date of the change:

- Data Aggregator Id

- Data Collector Id

- Energisation Status

- GSP Group Id

- Line Loss Class Id

- Measurement Class Id

- Meter Operator Id

- Profile Class Id

- Supplier Id

- Standard Settlement Configuration Id

• Upon receipt, from a Supplier, of changes to Metering System Registration Data the SMRA shall validate that the Supplier is liable for the SVA Metering System on the effective date of the change;

    • Upon receipt of changes to Meter Information Data or Meter Asset Provider from a SVA Meter Operator Agent, the SMRA shall validate that the SVA Meter Operator Agent is appointed for the SVA Metering System on the effective date of the change.

• The SMRA shall validate that the Line Loss Factor Class provided by the LDSO for an MSID is a valid Line Loss Factor Class for that LDSO as provided by the SVAA as MDDM;

• Upon receipt from a LDSO, of changes to Metering System Registration Data, the SMRA shall validate that the LDSO is the SVA Metering System’s LDSO as determined from the SVA Metering System Identifier;

• Upon receipt of creation details for a new SVA Metering System from the LDSO, the SMRA shall validate that SVA Metering System identifier contains the correct Distributor Id and does not already exist.

• Upon receipt of a Registration from a Supplier, SMRA will validate that the SVA Metering System identifier exists.

• Upon a change of Profile Class and / or Standard Settlement Configuration, the SMRA shall validate that the resulting combination of Profile Class and Standard Settlement Configuration are valid in the SVA Metering System’s GSP Group on the effective date of the change, as specified by the Average Fraction of Yearly Consumption Set data provided by the SVAA as part of Market Domain Data.

• An existing SVA Metering System, may only be registered for supply if, in respect of the SVA Metering System being registered:

- the LDSO has provided all the relevant data for which it is the source; and

- all the data for which the Supplier is the source have been provided.

- where the 1998 Trading Arrangement Indicator has been set to ‘Y’.

• A new SVA Metering System where the Energisation Status has not yet been provided, may be registered for future supply if, in respect of the SVA Metering System being registered:

- the LDSO has provided the MSID, GSP Group Id; and

- the Supplier has provided the MSID, Supply Start Date;

- and the 1998 Trading Arrangement Indicator has not been set to ‘N’.

then, prior to the Energisation Status being set to “energised” or “de-energised”, the SMRA shall validate that:

- the LDSO has provided all the relevant data for which it is the source; and

- the Supplier has provided all the relevant data for which it is the source.

• A SVA Metering System that has been disconnected i.e. has a Disconnection Date, may not be registered for dates after the disconnection date.

Where the SMRA has rules used in validating notifications to the SMRS which are additional to those specified in this BSCP, the SMRA shall declare them to the relevant Supplier and DA and shall only change these additional rules in accordance with the procedures specified in the REC.

4.4 Contact Notice Facility

The SMRA shall provide a Contact Notice Facility in accordance with this Appendix 4.4.

The SMRA shall make the Contact Notice Facility available in the following circumstances:

• The Old or New Supplier, in relation to the current or pending registration for a particular MSID, reasonably believes that the New Supplier has been erroneously registered for that MSID;

• The Old Supplier in relation to the current registration wishes to assign to the New Supplier a debt owing to it by a Customer at Domestic Premises in accordance with the Old Supplier’s Supply Licence;

• The Old or New Supplier in relation to the current or pending registration reasonably believes that the New Supplier applied to register an MSID which is a Related MSID without applying to register all the relevant Related MSIDs at the same time; and/or

• The Old Supplier makes a change to one of the data items for which it is stated to be responsible in the SVA Data Catalogue, in relation to a MSID, and its instruction to the relevant SMRA is rejected and the reason for such rejection is stated to be the New Supplier’s registration.

Where the SMRA receives more than 50 requests for the Contact Notice Facility on any Working Day and the SMRA cannot receive requests via the Managed Data Network (other than as a result of a failure of the Managed Data Network), the SMRA shall use reasonable endeavours to provide as many Contact Notices as possible but shall only be required to provide 50 Contact Notices using the following allocation:

• A maximum of five per Supplier allocated in the order that the requests are received;

• Where the above rule has been complied with, any extra Contact Notices which have been requested shall be provided in the order in which they have been requested; and

• Any extra Contact Notices in excess of 50 requested in any Working Day or received after 15:00 hours on a Working Day, which the SMRA has not provided, shall be deemed to have been the first requested at the start of the next Working Day.

4.5 Refreshes

Where BSCCo or the Performance Assurance Board (PAB) instructs a NHHDA to request a Full Refresh, the SMRA shall send, in instruction format, a Full Refresh containing all relevant data covering those Settlement dates for which a Final Reconciliation Run has not yet taken place at the time the Full Refresh is generated.

For Selective Refreshes, or additional Full Refreshes initiated by mutual agreement between the SMRA and the Data Aggregator, a shorter Settlement period may apply.

Where an SMRA receives more than 50 requests for a Selective Refresh on any Working Day, the SMRA shall use reasonable endeavours to provide as many Selective Refreshes as possible but shall only be required to provide 50 Selective Refreshes using the following allocation:

• A maximum of five per Supplier or Data Aggregator allocated in the order that the requests are received;

• Where the above rule has been complied with, any extra Selective Refreshes which have been requested shall be provided in the order in which they have been requested; and

• Any extra Selective Refreshes in excess of 50 requested in any Working Day or received after 15:00 hours on a Working Day, which the SMRA has not provided, shall be deemed to have been the first requested at the start of the next Working Day.

Where an SMRA receives more than 3 requests for a Full Refresh within a 5 Working Day period, the SMRA shall use its reasonable endeavours to provide as many Full Refreshes as possible, but shall only be required to provide Full Refreshes in response to the first 3 requests received during that 5 Working Day period within 15 Working Days of the request. Any further requests received during that 5 Working Day period shall be deemed to have been received on the fifth Working Day after the receipt of the first request.

4.6 Resends

Where the SMRA receives more than 50 requests for a Resend on any Working Day, the SMRA shall use reasonable endeavours to provide as many Resends as possible but shall only be required to provide 50 Resends using the following allocation:

• A maximum of five per Supplier or Data Aggregator allocated in the order that the requests are received;

• Where the above rule has been complied with, any extra Resends which have been requested shall be provided in the order in which they have been requested; and

• Any extra Resends in excess of 50 requested in any Working Day or received after 15:00 hours on a Working Day, which the SMRA has not provided, shall be deemed to have been the first requested at the start of the next Working Day.
