1. Introduction

1.1. Purpose and Scope of the Procedure

1.1.1 Purpose

This BSC Procedure (BSCP):

outlines the Change Management processes invoked to progress and implement changes to the BSC and BSC Configurable Items to ensure that all changes are introduced in a controlled and auditable manner.
defines the process for Third Party Applicants to request designation to raise a Modification Proposal; and
defines a pre-change process for Issues.

One of the objectives of this procedure is to maintain the integrity and robustness of the BSC Configurable Items and supporting products and to ensure that all changes are introduced in a controlled and auditable manner. This is achieved by:

implementing the change management procedures within the BSC;
assessing all proposed changes and assisting the BSC Panel and its Committees in making informed decisions;
consulting with interested parties how work will be progressed;
implementing new, or revisions to existing, BSC Configurable Items; and
producing the BSC Baseline Statements.

1.1.2 Out of Scope

This procedure does not cover changes to associated Core Industry products or the System Operator-Transmission Owner Code (STC). The System Operator within the STC is NETSO. However, where proposed changes to the BSC or BSC Configurable Items would result in a corresponding change to the Core Industry Documents or the STC BSCCo will liaise with the relevant bodies to ensure the appropriate change documentation is raised.

This procedure does not cover changes to BSC Parties’ or their Agents’ systems and procedures which may be necessary for participants to implement any changes that are made to the BSC or BSC Configurable Items. Party Agents must consider whether any potential changes would trigger the need for Re-Qualification by assessing the risk that implementing the corresponding changes within their own organisations would pose to the Balancing and Settlement arrangements as described in BSCP537.

1.1.3 Modification Proposals

A Modification Proposal is required to amend the BSC Sections. This procedure sets out the procedure for the submission of Modification Proposals, which is derived from Section F of the BSC (the ‘Modification Procedures’). Any consequential changes to BSC Configurable Items arising from a Modification Proposal may be made under that Modification Proposal and does not require a separate Change Proposal to be raised.

All interested parties, as listed in Section F of the BSC, may register (or be registered by BSCCo) to receive by email communications which support the Modification Procedures and fulfil BSCCo’s obligations in accordance with Section F of the BSC, by providing relevant contact details to BSCCo. The provisions concerning general email communications from BSCCo to Parties are contained in Section H of the BSC.

To raise a Modification Proposal, Parties must submit a completed Modification Proposal form to BSCCo. BSCCo must publish the Modification Proposal form template on the BSC Website for use by Parties. Guidelines for completing this form are contained within the form itself.

1.1.4 Change Proposals

A Change Proposal is required to effect changes to BSC Configurable Items where no changes to BSC Sections are required. To raise a Change Proposal, Parties must submit a completed BSCP40/02 ‘Change Proposal’ form to BSCCo in accordance with Section 3.4. Guidelines for completing this form are contained within the form. Section 3.5 sets out the process for obtaining the Panel Committee decision and Section 3.6 sets out the process for the implementation of Change Proposals.

1.1.5 Draft Change Proposals and Issues

This procedure also contains standard forms for raising Draft Change Proposals to allow participants to comment on or discuss a particular issue and solution prior to a Change Proposal being raised.

1.1.6 Change Proposal Circulars

Change Proposal Circulars (CPC) will be used to communicate all change management information relating to Change Proposals and related changes to Category 1 and 2 BSC Configurable Items to BSC Parties and Party Agents, in accordance with the process set out in Section 3.1. BSCCo publish all CPCs on the BSC Website.

Parties and their Qualified Agents should nominate individuals within their organisations to register as BSC Change Administrators (BCAs) and Party Agent Change Administrators (PACAs) respectively, to interface with BSCCo on all matters relating to changes to BSC Configurable Items. Please see section 3.11 of this procedure for more information on the registration process.

1.1.7 BSC Baseline Statement

The BSC Baseline Statement is a list of each BSC Section and BSC Configurable Item, showing:

the master version;
the effective date of the master version;
the Modification Proposals and / or Change Proposals implemented since the previous master version;
the “Responsible Committee(s)” for the approval of changes to it; and
the categorisation of BSC Configurable Item.

A new version of the BSC Baseline Statement will be produced when new versions of one or more BSC Sections and / or BSC Configurable Items become effective.

Submission of Issues

Where a Party or interested third party feels that it has an issue, problem, defect or improvement with the BSC arrangements, but is unsure of how or whether to progress the concern, or wants to explore the solution options, an Issue should be raised. This pre-change process shall assist in the framing of issue(s)/defect(s) and possible CPs or Modifications. Parties, interested third parties (including bodies representative of interested third parties and Party Agents) and BSCCo, may raise an Issue in accordance with section 3.15 below.

Panel Committees may be consulted by the proposer of the Issue in order to seek guidance. The Panel Committees would then advise on any possible solution to the concern and how best to resolve the problem, e.g. to raise a Change Proposal, or form an Issue Group.

Issue Groups shall adhere to the Issue Group Terms of Reference, which shall be set and maintained by the Panel and published on the BSC Website.

Unless an Issue is withdrawn by the proposer, an Issue Report shall be presented to the Panel following the assessment and discussion of the Issue.

1.2 Main Users of the Procedure and their Responsibilities

The main users of this procedure are:

BSCCo – manages the change process.
BSC Panel.
BSC Change Administrator (BCA) – nominated by BSC Parties to interface with BSCCo on all change issues.
Citizens Advice and Citizens Advice Scotland
Market Index Data Providers (MIDP).
Panel Committees - control all changes to Configurable Items, apart from modifications to the BSC.
Party Agent Change Administrator (PACA) - nominated by a Qualified Party Agent, or an applicant for Qualification, to interface with BSCCo on all change issues (note that PACAs cannot raise DCPs or CPs in their own right, but could ask a Party to raise them on their behalf).
Interested third parties (including Party Agents) or any bodies representative of interested third parties – to raise Issues.
Third Party Applicants – to request designation by the Panel or the Authority to raise Modification Proposals.

BCA/PACA participation in the Change Management of BSC Configurable Items

BCAs and PACAs are invited to comment on amendments to BSC Configurable Items during the change management process:

Draft Change Proposal Consultation

During the change management process, Draft CPs may be issued as part of the agreed timetabled Change Proposal Circular to BCAs/PACAs for consultation. For more information on this process, please see section 3.2 of this procedure.

CP Impact Assessment

During the change management process, CPs will be sent to BCAs/PACAs as part of the agreed timetabled Change Proposal Circular, detailing the issue and solution for Impact Assessment. BCAs/PACAs are invited to comment on CPs and their attachments and, where relevant, review associated draft redline changes. BCAs/PACAs will be expected to comment on support for the CP, detail impacts of the CP, provide implementation notification timescales and agree the proposed Implementation Date (if they do not, they will be asked to provide an alternative Implementation Date). The timetable for BCA/PACA CP Impact Assessment is available as part of the Change Register published on the BSC Website. For more information on this process, please see section 3.4 of this procedure.

Please note that De Minimis BMRS CPs will not be subject to the full Impact Assessment process (as described in 3.4 below), unless queried during the objection window.

Panel Committee Approval of Change Proposals

Once the appropriate Panel Committee(s)¹ has approved a CP, and associated redlined text, the CP becomes final and no further versions of the CP, or amendments to the redline text, can be produced without the raising of a separate Change Proposal.

3.4 Raising a Change Proposal for Impact Assessment

Housekeeping CPs do not require Impact Assessment and once raised in accordance with the following process, will be submitted to the relevant Panel Committee(s) for decision in accordance with section 3.5 of this BSCP. De Minimis BMRS CPs do not require a consultation period and are therefore not subject to 3.4.9 through to 3.4.12. The relevant Panel Committee(s) will decide whether a CP should be progressed as a Housekeeping or De Minimis BMRS CP.

Any BCA or PACA can object to the Panel Committee’s decision to treat a CP as Housekeeping or De Minimis BMRS, by using the objection process in section 3.5. Where an objection is received, BSCCo will progress the CP through the normal Impact Assessment and Panel Committee decision processes as a regular CP (i.e. a non-Housekeeping and a non-De Minimis BMRS CP). Because of the objection window, the Implementation Date for a Housekeeping or De Minimis BMRS CP shall not be earlier than 16 WDs after the date that BSCCo gives notification of the relevant Panel Committee’s decision under section 3.5.

Under certain circumstances, and with the approval of the appropriate Panel Committee(s), a regular CP can be progressed through the Impact Assessment process with a reduced timescale.

Following discussions with BSCCo, any changes required following those discussions, the CP should be updated to v1.0. Should any further amendments/additions/deletions be required to the CP during its lifecycle, the version number should be updated to v2.0, v3.0, etc.

To which section of the Code does the CP relate, and does the CP facilitate the current provisions of the Code? – All CPs should be raised in line with BSC section F 3.1.2 ensuring that changes to BSC Configurable Items should continue to facilitate the provisions as detailed in the Code and should not impose new obligations or restrictions of a material nature on Parties and Party Agents (or classes thereof) which are not authorised or envisaged by, or subsidiary to, the rights and obligations of the Parties under the Code. As such the originator should highlight the section of the BSC that their proposed change is derived from and if the proposed CP facilitates the existing arrangements in the BSC.

Requested Implementation Date and Associated Reasons – mandatory by originator – identification of any critical milestone date(s) which need to be considered when generating possible solutions, with reasons for these. If change can be implemented at any time i.e. with no time constraints, this should be stated. This will be updated to the agreed Implementation Date once the Panel Committee has voted.

[insert registered office address]

[insert date]

Dear Sirs,

Application to be designated by the Panel as a Third Party Proposer pursuant to Section F2.1A.1 of the Balancing and Settlement Code

By writing this letter, and submitting a Designation Request Form and a draft Modification Proposal Form we are applying to be designated as a Third Party Proposer under the Section F (Modification Procedures) of the BSC.

Unless otherwise stated, or the context otherwise requires, any capitalised term in this letter shall have the meaning given to it in the BSC.

We acknowledge that we have obtained a copy of the latest versions of Section B (The Panel), Section C (BSCCo and its Subsidiaries), Section F and Section H (General) and Section X-1 (General Glossary) of the BSC as well as BSC Procedure 40 from the BSC Website.

In consideration of BSCCo and/or the Panel considering our application to be designated as a Third Party Proposer, we hereby agree with each of you that we shall be bound by:

a) the terms of Section B1, B3 and B4.6 (the Panel); Section C1 and C3 (BSCCo and its Subsidiaries), Section F (Modification Procedures) and Section H7.1, H8 and H9 (General) of the BSC; and

b) the terms of BSC Procedure 40,

for the purposes of our application to be designated as a Third Party Proposer and the consideration of our modification proposal under the Modification Procedures as if we were a party to the BSC for the purposes of those Sections and BSC Procedures.

We acknowledge and agree that:

a) during our application to be appointed as a Third Party Proposer the provisions of paragraph 2.1A of Section F (Modification Procedures) of the BSC provide a right of appeal to the Authority should the Panel reject our application and that should our application be rejected our sole and exclusive remedy will be to refer the matter for determination to the Authority in accordance with that paragraph and we accept that its determination will be final, conclusive and binding; and

b) we will not make any claim in damages or any other claim of a financial nature against Elexon Limited or any Panel Member and we hereby waive (to the fullest extent permitted by law) any such claim against Elexon Limited or any Panel Member and release each from any such liability in respect of any breach by Elexon Limited or the Panel of any provision of the Code or in tort (including negligence) or otherwise.

Nothing in this letter shall exclude or limit liability for death or personal injury resulting from negligence by Elexon Limited or any Panel Member or resulting from fraudulent misrepresentation.

This letter shall expire following the later of:

a) the final determination (whether by the Panel or the Authority) that we have not been designated as a Third Party Proposer;

b) the withdrawal of the Modification Proposal proposed by us; or

c) the final determination (whether by the Panel or the Authority) as to whether the Modification Proposal proposed by us should be approved or rejected.

This letter shall be governed by, and construed in all respects in accordance with, the laws of England and Wales.

Yours faithfully,

……………………………………………………………..

signed by [insert name] being a Director and signing this letter for and on behalf of [insert full name of company]

1 The BSC Baseline Statement specifies which Panel Committee(s) are responsible for the approval of each BSC Configurable Item.

2 Proposals raised by BSC Agents will only be validated and logged as a CP with BSCCo’s consent.

3 The relevant Committee will determine whether a CP should be progressed as a De Minimis BMRS CP

4 Proposals raised by BSC Agents will only be validated and logged as a DCP with BSCCo’s consent.

5 The relevant Panel Committee will decide whether a CP should be progressed as a Housekeeping CP.

6 Originators should be aware that if Central Costs are needed this can take between 5 and 15 Working Days.

7 The Change Submission Deadline is produced as part of the CPC batching timetable in Section 3.1.

8 Please note lack of any response to a CPC does not indicate a negative response.

9 Timescales for publication are determined in Section 3.1.

10 Where the Working Group consists of only BSCCo and the originator, with the aim of producing redline text in a CP, no approval will be sought from the Panel Committees.

11 Only one of the Panel Committees need agree that a Working Group is required in order for a Working Group to be established.

12 Some BSC Configurable Items are jointly owned by more than one Panel Committee, as specified in the BSC Baseline Statement, and so will require approval by each relevant Panel Committee

13 The Originating BCA may attend the Panel Committee meeting.

14 Implementation cut off is 6 months for system changes and 4 months for document only changes or as agreed by the Panel Committee.

15 This request should only be made where Elexon has identified that there would be insufficient time to develop the necessary changes to Configurable Items with the appropriate amount of notice to participants following notification of the Authority’s decision. The development of such changes would not commence until after submission of the relevant Final Modification Report to the Authority. If the Modification were subsequently rejected by the Authority, such changes would not be implemented.

16 Except where a Modification Proposal is considered to be a Self-Governance Modification Proposal

17 If Registration Forms are submitted by email, they must be sent from the named user account of the Senior Manager within the Qualifying Organisation.

18 Please note that Third Party Applicants can also appeal to the Authority where they disagree with the Panel’s decision not to designate them as a Third Party Proposer.
