2 Categories of Market Participants
This section covers the withdrawal processes relevant to each category of BSC Party or Central Volume Allocation (CVA) Party Agent.
There are other participants who may wish to withdraw from the market for example,
Distribution System Operators and
Supplier Volume Allocation (SVA)
Party Agents. These participants should contact the
BSC Service Desk for advice on withdrawing from the market as they are not covered in this document.
The following sections describe each category of BSC Party and Party Agent in more detail.
This guidance note deals with the following participation capacities:
Supplier;
Generator;
Non-Physical Trader;
Interconnector User;
Interconnector Error Administrator
Virtual Lead Party (VLP); and
Asset Metering Virtual Lead Party (AMVLP)
These are BSC Trading Parties entitled to supply electricity under the BSC arrangements at any time after completing the relevant Market Entry requirements.
Any
Supplier who wishes to withdraw from the BSC must coordinate the de-registration of its
Supplier role with the appropriate
Market Domain Data (MDD) Go Live date in accordance with
BSCP509: Market Domain Data, details of which will be provided during the initial discussions with Elexon. The de-registration of
Supplier Base BM Units will also be carried out in conjunction with the above date.
These are Trading Parties entitled to generate electricity under the BSC arrangements at any time after completing the market entry requirements.
2.1.3 Non-Physical Trader
These are Trading Parties who do not generate or supply electricity but who trade in the electricity market – for example financial brokers and power exchanges.
2.1.4 Interconnector User
An Interconnector User uses an interconnector to transfer energy to or from Great Britain.
An
Interconnector User who wishes to withdraw from the BSC should deregister its
Interconnector BM Units in accordance with
BSCP15: BM Unit Registration.
Interconnector Users should also contact National Grid to discuss its requirements which are distinct from the BSC Withdrawal process.
2.1.5 Interconnector Error Administrator
An Interconnector Error Administrator compares the total deemed volumes for all the Interconnector BM Units with actual meter reading data taken from the Interconnector Users.
2.1.6 Interconnector Administrator
The Interconnector Administrator is responsible for ensuring all the BM Unit Metered Volumes for Interconnector Users are sent to the Settlement Administration Agent (SAA).
VLPs are aggregators of SVA registered units for the sole purpose of participating in the provision of balancing services. They can participate in both the Balancing Market and Replacement Reserve market (introduced by Project TERRE).
2.1.8 Asset Metering Virtual Lead Party
Independent aggregators are defined as parties who bundle changes in consumer’s loads or distributed generation output for sale in organised markets and who do not simultaneously supply the customer with energy.
3 Prevention of Withdrawal
A Party may not withdraw from the BSC if:
The Final Reconciliation Settlement Run has not been carried out in relation to the last Settlement Day in which the Party Traded , or the corresponding Payment Date is not yet past;
The Party has any outstanding debts (any sums accrued and payable under the Code);
The Party has an outstanding positive Energy Imbalance and/or positive Information Imbalance in respect of the BSC Party;
There are any Metering Systems or BM Units registered;
There is outstanding Default capable of being rectified;
The Party is an Interconnector Error Administrator (IEA) and no replacement IEA has been appointed; and
The Party is an Interconnector Administrator (IA), no replacement IA has been appointed.
A
Party who wishes to withdraw earlier than the current 14 month process could satisfy the first three requirements above by requesting to transfer their
Party ID and all of its outstanding obligations and liabilities to another existing
Party. If approved, this would assign liabilities associated with some of the withdrawal criteria (as specified in
BSCP65) to another
Party, allowing the
Withdrawing Party to exit earlier than 14 Months. The new
Party would then follow the below withdrawal process to withdraw that
Party ID in 14months time once all the obligations under the BSC have been met. The process in
BSCP65 4.5A – Withdrawal from the
Code (
Transferring Party ID), should be followed.
This section covers all processes that may need to be undertaken by any participant prior to exiting the market. Some of the processes are performed separately and some in parallel with each other. Exit from the BSC arrangements can only occur on successful completion of all the relevant processes detailed below.
The following information should be read in conjunction with the Exit Checklist - Appendix 3 in
BSCP65.
You should contact Elexon prior to carrying out any of the following actions as information of those that are relevant will be provided in an ‘actions email’. Contact details can be found in section 5.
4.1 Submission of Withdrawal Notice
Parties applying to withdraw from the BSC must submit a
Withdrawal Notice to Elexon in line with
Section A of the BSC. The
Withdrawal Notice can be found in
BSCP65/03 and must be signed by a category
A or
S Authorised Signatory. This can be completed on the Self-Service Gateway (Elexon Kinnect
Customer Solution). If confirmation of existing Authorised Signatories is required please contact Elexon. Further details of Authorised Signatories and the various categories can be found in
BSCP38.
Step 1 - Submission of Withdrawal Notice
A Party must submit a Withdrawal Notice to Elexon via post or fax.
The Withdrawal Notice must be submitted at least 28 days prior to the Withdrawal Date specified on the Notice. Elexon will carry out final checks two business days prior to the Withdrawal Date to ensure all withdrawal criteria have been met.
Elexon will check that the Withdrawal Notice has been signed by the appropriate Authorised Signatory and that the details are correct.
Step 3 - Confirmation of receipt and actions
Following validation of the Withdrawal Notice Elexon will confirm the Notice has been accepted via email.
In addition Elexon will also send an email detailing the relevant actions required for the Party to complete the Withdrawal .
4.2 Communication Line Cancellation
Each withdrawing
Party must indicate whether they wish to cancel their High or
Low Grade Service. To place a formal request, Parties and
Party Agents will need to complete and submit a ‘Cancellation of High Grade/Low Grade’ form to Elexon. This form can be located on the BSC Guidance Note page of the
Elexon website.
Step 1 - Submission of Cancellation form
Upon receipt of the cancellation form, Elexon will validate the request and check that the cancellation request has been made for the correct Communication Line (LGS or HGS). The participant will be contacted if there are any problems with the form.
Step 2 - Placing the order and removal of Communication Lines
Within two working days of receipt, the details of the cancellation will be passed to the the BSC Central Services Agent (CGI). The participant will be contacted regarding the physical and commercial aspects of final disconnection.
Note that for cancellation of a Low Grade Service it is not necessary to physically disconnect the Communication Line.
Step 3 - Confirmation of removal
CGI will contact the participant to confirm actions taken to cancel the service, and that invoices relating to any
High Grade Services will cease at the end of the relevant month. If there are any problems with the cancellation, the participant should contact the Market Entry team at
market.entry@elexon.co.uk.
4.3 BSC and Trading Charges
As stated in section 3, a Party must clear all outstanding debts to withdraw from the BSC.
Upon submission of a Withdrawal Notice (or during the initial discussion with the Party), Elexon will identify if there are any sums accrued and payable relating to the Party. If this is the case, the Party will be informed by Elexon and they must ensure that payment of the outstanding amounts is cleared prior to the day of the final checks. Copy invoices can be obtained on request.
At this point, Elexon will also confirm with the Funds Administration Agent (FAA) if there are any outstanding Trading Charges that must be cleared prior to the withdrawal. Elexon will liaise with the Party to ensure that any issues are resolved.
Withdrawal from the BSC will not be permitted if the above charges remain outstanding on the day of the final checks.
Upon notification that a Party wishes to withdraw, Elexon will check there are no Trading Disputes affecting the Party. If any issues are identified then this will be discussed with the Party to determine if the withdrawal will be affected.
4.5 Retrieval of Credit Cover
Elexon will inform the
Party if there is any credit cover lodged. If so, a Minimum Eligible Amount (MEA) request (via
BSCP301) to the
Energy Contract Volume Aggregation Agent (
ECVAA) must be submitted at least
29 days after the last day of trading to retrieve this. A MEA request is from a
Party to
ECVAA to calculate the minimum amount of
Credit Cover that they are permitted to withdraw at one time. The calculation is performed over a 10-day period, and if the minimum eligible amount is zero, the
Party is permitted to withdraw all of its credit cover. The actual request to withdraw funds must be submitted within two working days of the
ECVAA notification of the minimum eligible amount to the
Party.
If there are any questions regarding the forms or process, the FAA will be able to assist.
If a Party is in Default solely due to administration and wishes to retrieve credit cover this can be done once the final withdrawal checks have been completed. Therefore the Minimum Eligible Amount request must be submitted 15 days prior to the proposed Withdrawal Date, confirmation of this date will be provided by Elexon.
4.6 Cancellation of Authorisations
Following completion of the withdrawal checks by Elexon, all Parties,
Energy Contract Volume Notification Agents (
ECVNAs) and
Metered Volume Reallocation Notification Agents (
MVRNAs) must cancel their Authorised Signatories in accordance with
BSCP38. This involves completing the relevant sections in two forms –
BSCP38/5.1 Part B and
BSCP38/5.3 Part B which can be completed on the Self-Service Gateway (Elexon Kinnect Customer Solution).
4.7 Deregistration of Party Agent Role/s
A withdrawing Party may wish to cancel any Party Agent roles they have registered. The following process will enable this.
4.7.1 Termination of ECVNA/MVRNA Authorisations
A
Party will need to terminate any
ECVNA or
MVRNA authorisations they have in place by submitting
BSCP71/03 and 04 forms to Elexon. This can be done through the Self-Service Gateway (Elexon Kinnect
Customer Solution). When specifying the Effective To Date, the
Party should ensure there are no non-zero contract notifications in place which would affect any period on or subsequent to the specified Effective To Date.
4.7.2 Deregistration of ECVNA and MVRNA roles
Upon cancellation of any
ECVNA and
MVRNA authorisations, a
Party should deregister its
Party Agent role/s. This must be done using a
BSCP71/06 form:
ECVNA or
MVRNA De-Registration Form.
Step 1 - Submission of BSCP71 (06)
Elexon validates the form ensuring it has been signed by the appropriate Authorised Signatory. Elexon will then request confirmation from the NETA Central Services Agent that there are no authorisations in place relating to the Party ID affecting any Settlement Period after the proposed Effective To date. If this request comes back as nil, Elexon will authorise the deregistration with the Effective To Date stated on the form.
Step 3 - Confirmation of Deregistration
The NETA Central Services Agent will confirm to Elexon when the form has been processed. The Party will be only contacted if there are problems with the process.
4.8 Deregistration of a Participation Capacity
Once a
Party has completed the termination of all
ECVNA and
MVRNA authorisations it is necessary to deregister remaining roles using the
BSCP65/01 form.
Step 1 – Submission of BSCP65/01
BSCP65/01 must be submitted to Elexon by email. This can be done using the Self-Service Gateway (Elexon Kinnect
Customer Solution). On this form an Effective To Date for the roles they wish to de-register (i.e.
Trading Party - Generator) must be set.
The Effective To Date on the form can be set prior to the proposed Withdrawal Date and must be at least two working days in the future to ensure the form can be processed in time.
Elexon validates the form ensuring it has been signed by the appropriate Authorised Signatory. Elexon will then request confirmation from the BSC Central Services Agent that there are no authorisations in place relating to the Party ID affecting any Settlement Period after the proposed Effective To Date. If this request comes back as nil, Elexon will authorise the deregistration with the Effective To Date stated on the form.
Step 3 - Confirmation of Deregistration
The NETA Central Services Agent will confirm to Elexon when the form has been processed. The Party will only be contacted if there are problems with the process.
