1. Reference is made to the Balancing and Settlement Code and, in particular, to the definition of “BSC Procedure” in Section X, Annex X-1 thereof.

2. This is BSC Procedure 71 Version 17.0 relating to the submission of Energy Contract Volume Notifications (ECVNs) and Metered Volume Reallocation Notifications (MVRNs).

3. This BSC Procedure is effective from 01 October 2024.

4. This BSC Procedure has been approved by the Panel.

1 Introduction

1.1 Purpose and Scope of the Procedure

The purpose of this BSCP is to enable the submission of Energy Contract Volume Notifications (ECVNs) and Metered Volume Reallocation Notifications (MVRNs) to the Energy Contract Volume Aggregation Agent (ECVAA). It describes the process for submitting notifications, and replacing previously submitted notifications.

The procedure enables participants who wish to become Energy Contract Volume Notification Agents (ECVNA) or Meter Volume Reallocation Notification Agents (MVRNA) to register as such Party Agent types with the Central Registration Agent (CRA). It then enables each Party to authorise an ECVNA or MVRNA for the purpose of providing ECVNs or MVRNs to the ECVAA.

Notification authorisation may be established on a single basis, where the same ECVNA or MVRNA is appointed by both Parties. In addition the procedure also caters for a single Party wishing to provide to ECVAA, ECVNs related to its two Energy Accounts.

In the case of ECVNA Authorisations, Parties must also use this procedure to specify whether for a given Authorisation, notification amendments should be processed on an additional or replacement basis, or whether both amendment types should be accepted. Whether an Authorisation allows an ECVNA to submit additional, replacement or both types of ECVN is its Notification Amendment Type.1 This procedure explains how Parties may change the status of an Authorisation’s Notification Amendment Type.

The procedure describes the process by which ECVNs and MVRNs are submitted by ECVNAs and MVRNAs, and provides details of the data required in a valid notification. It also provides details of the rules for:

    • Refusal or rejection of an otherwise valid notification because of Credit Default;

    • Termination of ECVNA and MVRNA Authorisations; and

    • Procedures to allow Contract Trading Parties to nullify all notified volumes between two accounts providing all authorisations between those accounts have already been terminated. (Note that this nullification procedure is not selective: specification occurs at the BSC Party level and is for use when it is imperative to nullify all notified volumes between a Party and Counter Party).

In addition, the procedure allows Parties, ECVNAs and MVRNAs to specify changes to their ECVAA notification feedback reporting options for each authorisation (including the ability to opt out of receiving reports).

Upon successful completion of registration, applicants will be able to access the ECVAA Web Service. For further information contact the BSC Service Desk.

Where a Party has access to the Self-Service Gateway and an equivalent online form is provided, the Party may use the online form as an alternative to the paper forms defined in this BSCP.

Where a Party has provided data using the Self-Service Gateway, BSCCo may use the service to validate and confirm the input data or to request additional data. Where this is the case, these online transactions will represent a valid equivalent to the transactions defined in this BSCP.

MVRNs cannot be submitted in relation to Secondary BM Units.

1.2 Main Users of Procedure and their Responsibilities

This BSCP should be used by:

    • ECVNAs and MVRNAs to register with the CRA;

    • Contract Trading Parties and ECVNAs/MVRNAs to submit joint authorisations or individual terminations including reporting requirements;

    • BSCCo and CRA to receive and process registration applications;

    • ECVAA to receive and validate authorisations and terminations and to process requests to ban / unban EWS users.

    • ECVNAs and MVRNAs to submit ECVNs and MVRNs to the ECVAA;

    • ECVNAs and MVRNAs to change their registration details (including de-registration); and

    • Contract Trading Parties to request the nullifications of any outstanding volumes between two accounts when all authorisations between those accounts have been terminated.

1.3 Balancing and Settlement Code Provisions

This procedure should be read in conjunction with the Code and in particular Section P.

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

3.11 Nullification of Notification Volumes by Request

Parties should be aware that when using this procedure it is not possible to be selective about which set of notified volumes to nullify. This procedure is intended to be used when it is imperative to nullify all notified volumes between the two specified Party Energy Accounts on form BSCP71/10. Parties must ensure that all ECVNA and/or MVRNA Authorisations have been terminated as any outstanding ECVNA and or MVRNA Authorisations will result in the request being rejected.

4.16 Notification Submission

4.16.1 Notification Data

Whenever submitting an ECVN or MVRN, the following data must be submitted to the ECVAA by the relevant Notification Agent, or it will fail validation and will not be entered into the ECVAA database for use in Settlement (as described in section 4.17.1 of this BSCP).

For ECVNs:

    • ECVNA identifier(s);

    • ECVNAA Identifier under which the ECVN is being submitted;

    • ECVNAA Key(s);

    • ECVN Identifier;

    • Effective From Date and if required, Effective To Date;

    • Energy Contract Volume Period Data in MWh for each Settlement Period affected by the notification and corresponding to each Energy Account identifier. (Any omitted Settlement Periods will be treated as having an Energy Contract Volume of zero).

The MWh values in an ECVN represent an amount of energy transferred from the first Energy Account identified in the ECVNAA, to the second Energy Account identified in the ECVNAA.

For MVRNs

    • MVRNA identifier(s);

    • MVRNAA Identifier under which the MVRN is being submitted;

    • MVRNAA Key(s);

    • MVRN Identifier;

    • Effective From Date and if required, Effective To Date;

    • Metered Volume Reallocation expressed as a fixed reallocation and a percentage reallocation for each Settlement Period. (Any omitted Settlement Periods will be treated as having a Metered Volume Reallocation of zero).

Note that an ECVN or MVRN contains two Authorisation Identifiers: one identifying the Authorisation under which the notification is being submitted, and one contained within the ECVN Identifier or MVRN Identifier. These will be the same, except when a notification is intended to replace a notification submitted under a different Authorisation (as described in 4.16.3 below).

In respect of notifications that cover more than one day, defaulting rules will be applied by the ECVAA for any clock change days covered by the notification, which for short days will ignore values submitted in respect of third and fourth Settlement Periods, and for long days will repeat values submitted for the third and fourth Settlement Periods.

4.16.2 Addition Notifications

A new notification with a different notification identifier (ECVN Identifier or MVRN Identifier) to a previously-submitted notification will add to any existing notifications submitted with the same authorisation identifier.

4.16.3 Replacement Notifications

An existing ECVN or MVRN may be replaced by submitting a notification with the same ECVN Identifier or MVRN Identifier as an existing notification, for any valid range of effective dates. This will then be treated by the ECVAA as an amendment to the original notification, and will be processed as follows:

    • Any data contained within a replacement notification for Settlement Periods that have passed the Submission Deadline will be disregarded.

    • The notification amendment will overwrite the previously-submitted notification from the Effective From Date of the new notification. The effect of the original notification will therefore be terminated for all Settlement Periods from the Effective From Date of the new notification, including any Settlement Dates and Settlement Periods after the Effective To Date of the new notification.

    • A replacement notification in which data for specific Settlement Periods is omitted will result in the Energy Contract Volumes or Metered Volume Reallocations previously notified for those periods being withdrawn.

    • A replacement notification with no Energy Contract Volume or Metered Volume Reallocation data for any Settlement Periods will result in the original notification being withdrawn in its entirety from the Effective From Date of the new notification.

While an ECVNAA or MVRNAA remains in force, notifications submitted under that Authorisation can only be replaced by notifications submitted under the same Authorisation. However, once an ECVNAA or MVRNAA has been terminated, notifications previously submitted under it can be replaced by notifications submitted under another Authorisation, provided that it relates to the same Energy Accounts (for an ECVNAA) or Lead Party, Subsidiary Party and Primary BM Unit (for an MVRNAA).

4.16.4 Notification Amendment Type

In the case of an ECVN, where the associated ECVNAA has a Notification Amendment Type of either ‘Additional’ or ‘Replacement’, the ECVAA shall reject any notifications that do not contain the appropriate combination of ECVN and ECVNAA identifiers in accordance with the rules in Sections 4.16.2 and 4.16.3 above. This ensures that an ECVNA cannot submit an additional notification in error when it was intending to effect a replacement, or vice versa.

It is assumed that the Notification Amendment Type for any Authorisation pre-dating the P309 implementation date is set to ‘both’ unless the Relevant Contract Parties and agents update it by an Authorisation Change or a successor Authorisation.

4.17 Notification Validation

Upon receipt of an ECVN or MVRN, the ECVAA carries out a series of checks to confirm the validity of the notification. These checks include the following:

    • confirmation that the notification contains the data as required above;

    • checks on the consistency of the identifiers and keys against those held by the ECVAA;

    • check on validity of the ECVNAA/MVRNAA for the Calendar Day on which the notification was received;

    • confirmation that the notification Effective To Date (if specified) is not before the current day, and not before the Effective From Date;

    • confirmation that the ECVN/MVRN for each Settlement Period has been received at or before the Submission Deadline, with any data for Settlement Periods for which the Submission Deadline has passed being disregarded by the ECVAA;

    • checks on the value of the Contract Volumes or Volume Reallocations requested in the ECVN/MVRN to ensure they are within permissible ranges;

    • for ECVNs, where the associated ECVNAA has a Notification Amendment Type of ‘Additional’ or ‘Replacement’, check that the use of ECVN and ECVNAA identifiers is consistent with the rules in Section 4.16 for additional and replacement notifications respectively.

Where any data for a Settlement Period is omitted from a notification, the notification is accepted but an Energy Contract Volume or Metered Volume Reallocation of zero being applied to the affected Settlement Periods.

In all other instances, where data for any Settlement Period within the notification fails validation, the notification is rejected in its entirety.

4.18 Credit Checking

The ECVAA continually checks the effect of ECVN/MVRNs on the associated Parties’ Energy Indebtedness and refuses or rejects notifications which have the effect of increasing a Party’s Energy Indebtedness while their Credit Cover Percentage is greater than 90% and the Credit Default Authorisation Flag has been set by BSCCo. These processes of refusal and rejection are described in sections 4.18.1 and 4.18.2 below.

In the case of both refusal and rejection, a valid notification that has a neutral effect on Energy Indebtedness, or which consists of Energy Contract Volumes or Metered Volume Reallocations with zero values, will not be considered as increasing a Party’s Energy Indebtedness.

4.18.1 Refusal of Entire Notifications

When a Party is in Level 2 Credit Default (i.e. has Credit Cover Percentage greater than 90% and the Credit Default Authorisation Flag set, as described in 4.18 above), and a notification is received during the Credit Default Refusal Period that has the effect of increasing Energy Indebtedness in any Settlement Period, the notification is refused in its entirety and is not entered into Settlement, regardless of whether the notification is otherwise valid.

4.18.2 Rejection of Notifications in Respect of a Settlement Period

For notifications already in the ECVAA system and relating to Settlement Periods within the Credit Default Rejection Period, any valid notifications that increase Energy Indebtedness are rejected on an individual Settlement Period basis. Any notifications for Settlement Periods within the Rejection Period that are valid and do not increase the Parties’ Energy Indebtedness are accepted.

1 It is assumed that the Notification Amendment Type for any Authorisation pre-dating the P309 implementation date is set to ‘both’ unless it is updated by an Authorisation Change or a successor Authorisation.

2 If an Authorisation is requested using Electronic File Data Transfer, the passwords and signatures are not required as the access control to the participant system is sufficient authentication. Where faxes are used, participants are required to submit hard copies of the forms by post in case the faxed signatures are illegible.

3 Please note that Parties and Party Agents must first request to receive reports using flexible reporting as detailed in BSCP41. These reports will be the default versions of the feedback reports. Subsequently, the reporting requirements at an authorisation level can be changed using form BSCP71/11 as detailed in section 3.12.

6 The ECVAA will process Authorisation termination requests within 1 business hour of receipt when received between 8:00am and 5:00pm on Working Days (Monday-Friday) and 8:00am to 11:00am on all other days. Authorisation termination requests received outside these working hours will be processed immediately at the start of the next Working Day

7 The termination effective date will be set to the calendar day on which the termination request is processed.

8 The ECVAA will process all Authorisation termination requests within 1 hour of receipt when received between 8:00am and 5:00pm on Business Days (Monday- Friday) and 8:00am and 11:00am on all other days. Authorisation termination requests received outside of these working hours will be processed immediately at the start of the next day

9 Applicants with access to the ECVAA Web Service should set the effective to date on any credentials files to a date no later than the effective to date entered on the De-registration form. It should be noted that a participant without a current registration for the role it is logging into the ECVAA Web Service with, will be denied access. However, it is good practice to end date credentials files to before or on the de-registration date.

10 Authorisation Report (ECVAA-I013): Although this is an ECVAA flow, this is shown as a CRA responsibility in this process as the CRA co-ordinates the Party Agent de-registration process.

11 If there are associated Authorisation Termination Requests with this Volume Notification Nullification Request, then the Authorisation termination requests must be faxed/emailed first, the associated Authorisation termination field on form BSCP71/10 is a guide only, the ECVAA will not wait to receive both before it starts processing the forms.

12 This hour, and the time of issue, must fall within a Business Day (9am – 5pm) and requests must always be processed in 60 minutes.

13 Please note that failure on ECVAA’s part to contact either the Requesting Party or Counter Party will not cancel or delay the nullification processing.

14 An authorised person registered under category K in BSCP38 (Submission of ECVNA or MVRNA Authorisations)

15 The electronic submission may be generated either by the ECVNA’s or MVRNA’s own notification system, or by using the EWS. Submissions made through the EWS are validated and acknowledged by the online screens, and for that reason electronic ACKs and NACKs (as described in step 3.15.2) are not sent for EWS submissions.

16 ECVNAs, MVRNAs and Contract Trading Parties may specify their feedback reporting requirements in accordance with Section 3.12 Report Requirement Change Request and BSCP41 (‘Report Requests and Authorisation’).

17 In the event that ECVAA does not send rejection feedback within 20 minutes of receipt, the ECVNA/MVRNA may be entitled to resubmit the notification in accordance with paragraphs P2.3.10 and P3.3.10 of the BSC.

18 Following an ECVAA System Failure, a Party may request transmission of corrected Notification Reports in relation to a Settlement Day (via the BSC Service Desk).

19 An ‘empty’ Forward Contract Report will be sent if no notifications have been made for the Party.

20 The default Forward Contract Report starts from the first Settlement Period that has not Gate Closed. An alternative report format, which starts from Settlement Period 1 on each Settlement Day, may be requested via BSCP41 Flexible Reporting.

21 A Party Agent registering as an ECVNA and MVRNA can elect to allocate the same Party Agent ID to both Party Agent capacities

22 P210 was approved by the Authority on 29 March 2007 with the retrospective implementation date of 5 February 2007.
