Balancing Mechanism(BM) Units |
Guidance Note |
BM Units can be classed as either Primary or Secondary BM Units.
Primary BM Units are the units used under the Balancing and
Settlement Code (
BSC) to account for all energy that flows on or off the
Total System (the
Transmission System and each
Distribution System combined). A
Primary BM Unit is the smallest grouping of generation and / or demand equipment that can be independently metered for
Settlement and all generation and demand equipment must be captured in a
Primary BM Unit.
Secondary BM Units can be registered by Virtual Lead Parties (VLPs) and Asset Metering VLPs (AMVLPs). Supplier Volume Allocation (SVA) Half Hourly (HH) metered generation and / or demand equipment within a single Grid Supply Point (GSP) Group can be allocated to a Secondary BM Unit for the purpose of providing Balancing Services to the National Electricity Transmission System Operator (NETSO). This equipment will also be registered in a Primary BM Unit.
Where equipment is in both a Primary and Secondary BM Unit, the Supplier is responsible for the Settlement of the Primary BM Unit and should contract for all the energy required to balance that BM Unit. If the equipment is also in a Secondary BM Unit and is called upon by the NETSO for Balancing Services, Settlements will adjust the Primary BM Unit so that the Supplier is not affected.
Note that an SVA Metering System or an Asset Metering System must only be providing Balancing Services through one BM Unit (Primary or Secondary) at any particular time to prevent double counting in Settlement.
Accessing the Elexon Kinnect Customer Solution
As part of the Market Entry process you will be provided access to the
Customer Solution. To register the relevant
BM Units please log into the Elexon Kinnect
Customer solution. You can complete and submit the information in the
Customer Solution if you are a Category A signatory or complete the information as an Assistant and send it to a Category A signatory to approve and submit. For information on accessing the Elexon Kinnect
Customer solution, please refer to: ‘
FAQs when using the Kinnect Customer Solution’.
Guidance is provided below on how to register the relevant BM Units for your role.
What do I need to do before I can register BM Units?
Before registering a BM Unit you need to complete or be in the process of completing Market Entry for the relevant BSC Party Role.
If you are registering a
BM Unit for a
Generating Unit that is associated with a
Licensable Generating Plant, the BSC
Party registering the
Generating Unit must be the person that generates
electricity at that
Generating Plant. You will need to complete Market Entry as a
Trading Party – Generator to register the
BM Unit. If you are unsure if your activity is licensable please contact the Ofgem Licensing team at
licensing@ofgem.gov.uk.
If you are registering a BM Unit Generating Unit that is associated with a Licence Exempt (Exemptable) Generating Plant, the BSC Party registering the Generating Unit can be either:
You will need to complete Market Entry as either a Trading Party – Generator or Trading Party - Supplier to register the BM Unit. Note that you could register the Primary BM Unit to another BSC Party (e.g. a Supplier with whom a Generator may have a Power Purchasing Agreement (PPA) offtake arrangement) if you have a short timescale before the intended energisation date in which to go through the Market Entry process to qualify as a Generator.
If you are registering a BM Unit for trading over one of the Interconnectors, you need to complete Market Entry as a Trading Party – Interconnector
If you are registering Supplier BM Units you need to complete Market Entry as a Trading Party – Supplier.
If you are registering a Secondary BM Unit, you need to complete Market Entry as a Virtual Lead Party (VLP) or Asset Metering Virtual Lead Party (AMVLP).
If you wish to participate in the Balancing Mechanism (i.e. you wish to submit Physical Notifications (PNs) to the NETSO) you must contact the NETSO, to discuss any obligations and sign the necessary contractual agreements.
The BSC Primary BM Unit registration is separate to the NETSO BM Unit registration; however the Effective From Date for your BSC Primary BM Unit will need to be agreed with the NETSO.
When you contact the NETSO BM Unit registration team, the NETSO will provide you with the NGC BM Unit Id. Where you provide an NGC BM Unit Id and where the Final Physical Notification Flag (FPN) = Y, the CRA will ask the NETSO for approval of the registration and intended Effective From Date.
The Grid Code requires that Primary BM Units submit Physical Notifications (PNs) to the NETSO if their Generation or Demand Capacity is at or above 50MW in England and Wales, 30MW in South Scotland or 10MW in North Scotland. It is optional below these limits. Interconnector Primary BM Units always submit PNs. Secondary BM Units normally submit PNs.
Please note that if the NGC BM Unit requires new Electronic Data Transfer (EDT) and Electronic Dispatch Logging (EDL) to be installed there can be significantly longer lead times to install these than the BSC Primary BM Unit registration process. You should therefore aim to start your NCG BM Unit registration well in advance of your connection date to ensure that the timescales for your BSC Primary BM Unit registration are not impacted.
There are several types of BM Unit, each representing different aspects of the system. Each type is marked with prefixes in their IDs, as given below. Each type is described separately in the following sections, along with an overview of the registration process and what you need to do.
If you are only interested in a particular type of BM Unit, refer to the relevant section. The list below describes each type:
BM Unit Type | Prefix | Overview |
Directly Connected | T_ | Primary BM Units directly connected to the Transmission System. |
Embedded | E_ | Primary BM Units embedded within a / connected to a Distribution System. |
Interconnector | I_ | Primary BM Units related to an Interconnector. |
Supplier | 2_ | Primary BM Units covering Supply. These contain all of a particular Supplier’s Meters for a given Grid Supply Point (GSP) Group in either a Base or Additional Supplier Primary BM Unit. |
C_ | These Additional Supplier Primary BM Units are registered solely for the purpose of allocating Contracts for Difference (CfD) Assets. |
Secondary | V_ | Secondary BM Units may be registered by a VLP or AMVLP to provide Balancing Services to the NETSO. |
Miscellaneous | M_ | Other types of Primary BM Units that don’t fit the above categories. This prefix does not apply to newly registered Primary BM Units. |
Exempt Export Primary BM Units
Some
Generating Plants are ‘Exemptable’, which means that the
Lead Party doesn’t need a
Generation Licence to operate the
Plant. Some
Generating Plant may be
Class Exemptable, as set out in the
Statutory Instruments exempting them from the requirement to hold a
Generation Licence. Other
Generating Plant may be Exemptable if granted an Individual
Exemption by the
Secretary of State. If you are unsure if your activity is licensable or Exemptable please contact the Ofgem Licensing team at
licensing@ofgem.gov.uk.
The Lead Party of a Central Volume Allocation (CVA) Exemptable Generating Plant or the Supplier of a Supplier Volume Allocation (SVA) Exemptable Generating Plant can apply for the BM Unit containing the Exemptable Generating Plant to be granted exempt export status under the BSC. This means that the Lead Party or Supplier can receive Embedded Benefits(if embedded) and choose the BM Unit P/C flag (if embedded or directly connected).
Note that an Exemptable Generating Plant does not have to be included in an Exempt Export Primary BM Unit under the BSC; however exemptable benefits can only be applied to Exempt Export Primary BM Units.
Standard and Non-Standard Primary BM Unit Configuration
The BSC requires that a
Primary BM Unit must satisfy the following criteria (
Section K3.1.2);
only one Party is responsible for the Exports and/or Imports from or to the Plant and/or Apparatus registered in Central Meter Registration Service (CMRS) (another Party may be responsible for an Supplier Meter Registration Service (SMRS) registered connection as in point (d));
the Exports and/or Imports relating to the Primary BM Unit are capable of being controlled independently of any other Exports and/or Imports which do not relate to the Primary BM Unit;
the Metered Volumes from the Primary BM Units Plant and Apparatus are submitted separately from any Plant and Apparatus not part of the Primary BM Unit
the Primary BM Unit does not contain Plant and/or Apparatus whose Imports and Exports are measured by both CVA and SVA Metering Systems except where:
the Registered Capacity of the Boundary Point measured by the Metering System(s) registered in SMRS is equal to or less than the limit determined by the Panel, currently 415V;
the Plant and Apparatus cannot Export through the Metering System registered in SMRS; and
there are measures in place to prevent instantaneous flow through of electricity:
from the Metering System registered in CMRS to the Metering System registered in SMRS; and/or
between different Systems such as the Transmission System and the Distribution System or between different Distribution Systems;
i.e. a backup connection to the Distribution System with registered capacity of less than 415V and with Metering systems registered in SMRS is allowed; and
Plant and Apparatus with a Registered Capacity of less than or equal to the size of a Small Power Station may be aggregated up to the size of a Small Power Station (size applicable to both Imports and Exports) within a single Primary BM Unit. A Primary BM Unit comprised of Plant and Apparatus with a Registered Capacity of greater than the size of a Small Power station must be the smallest aggregation of the Plant and Apparatus for which the requirements mentioned in (a) to (c) would be met.
In addition to
Primary BM Units meeting the criteria above, the BSC states a number of exceptions that are also considered to be a single
Primary BM Unit (
Section K3.1.4). These are included in the list Permissible Configurations of
Plant and
Apparatus on page on page 9 below;
Any configuration that does not meet the criteria above or is not on the list of single Primary BM Units in the BSC could be registered as a Non-Standard Primary BM Unit. The configuration of Non-Standard Primary BM Units need to be approved by the Imbalance Settlement Group (ISG) and this results in a 60 Working Day lead time.
If you need to apply for a Non-Standard
Primary BM Unit, you will need to complete and submit a
BSCP15/4.13 form accompanied by electrical single line diagrams to Elexon explaining why you believe that the Non-Standard configuration is more appropriate than a standard one. Alternatively, the electrical single line diagrams can be submitted via the Self-Service Gateway (Elexon Kinnect
Customer Solution) as part of the
BM Unit registration. All Non-Standard
Primary BM Units are different so please contact the Elexon Participant Management team prior to applying for a Non-Standard
Primary BM Unit as we can provide advice on the appropriateness of your proposals, the timescales and the requirements of your application form. As a minimum, your form should contain:
A description of the Plant and Apparatus, where it connects to the Total System and the location of the Metering Equipment with reference to the electrical single line diagram; and
The Plant and Apparatus that is to be included in each of the Non-Standard Primary BM Unit(s) and any other Standard Primary BM Units at the boundary point(s) with reference to the electrical single line diagram; and
The clause(s) of BSC Section K 3.1.2 that the Non-Standard Primary BM Unit does not satisfy and why; and / or
The benefits of the Non-Standard Primary BM Unit configuration compared to a different configuration and / or the limitations of a different configuration; and / or
Any relevant costs associated with the Non-Standard Primary BM Unit configuration (as opposed to a Standard Primary BM Unit configuration if appropriate), e.g. metering costs, BSC Costs.
The
BSCP15/4.13 form is sent by Elexon to the NETSO for comment and to the ISG for decision. If the form is sent in Microsoft Word, we will remove the contact and authorised signatory information before sending it on. If the form is sent in PDF, please could you also send a copy without contact and authorised signatory information.
Please also note that as the diagrams need to be provided to ISG, the file size of an email containing diagrams should be kept below 4MB by compressing files or splitting into several files if necessary.
You can request that your application is considered in the confidential session of the ISG meeting, however the ISG encourages applications to be heard in the open session. If parts of your application are confidential, we can provide those parts to the ISG on a confidential basis (e.g. electrical single line diagrams). If you wish your whole application to be heard in the confidential session, the ISG asks that you provide the justification for this as part of your application.
Non-Standard Primary BM Units are presented to the ISG for decision taking into account the views of the NETSO. The ISG consider all applications on their individual merit. There is no guarantee that a Non-Standard configuration will be accepted, even if a similar configuration has previously been agreed. Any Party considering a configuration of Plant and Apparatus that may not be registered as a single Primary BM Unit is encouraged to consult the NETSO and seek approval for a Non-Standard Primary BM Unit from the ISG early in the design of the Plant and Apparatus.
The same Plant and Apparatus cannot be contained in more than one Primary BM Unit except in the following scenarios:
where different Parties are responsible for the Import to and Export from the same Plant and Apparatus. In this scenario each Party must register a Primary BM Unit, one for the Import and one for the Export;
where all or part of the Import to the Plant and Apparatus is metered by Metering Systems registered in both CMRS and SMRS. This may be a single Metering System registered in both SMRS and CMRS at a single Boundary Point or separate Metering Systems at separate Boundary Points. The Primary BM Units may be registered by the same or different Parties; or
Power Park Modules which belong to a Switching Group.
Where a Party is responsible for both the Imports to and the Exports from Plant and Apparatus, it cannot register separate Primary BM Units for the Import to and Export from the same Plant and Apparatus measured by the same Metering System.
Permissible Configurations of Plant and Apparatus
The following configurations of Plant and Apparatus are permissible in the BSC as single Primary BM Units. This list is not exhaustive. Other configurations of Plant and Apparatus would be permissible as single Primary BM Units if the configuration meets all the criteria for a Standard Primary BM Unit set out above:
Generating Unit (including Single Generating Unit Open Cycle Gas Turbine);
Closed Cycle Generating Turbine (CCGT) Module;
Power Park Module (PPM);
Power Station Transformers (Station Transformers)
Directly Connected Demand at a single Boundary Point Combined Offshore BM Unit (COBMU);
Directly connected Demand at more than one Boundary Point provided that the total Imports are equal to or less than 50MW in England and Wales, 30MW in South Scotland and 10MW in North Scotland;
Supplier (Base or Additional) Primary BM Unit;
Interconnector Primary BM Unit
Any BM Units that were determined as part of the transitional arrangements for the implementation of the British Electricity Trading and Transmission Arrangements (BETTA)
An Offshore PPM or COBMU and its associated Low Voltage Assets
Combination of Generating Units connected to the Total system provided that the total Exports are equal to or less than 50MW in England and Wales, 30MW in South Scotland and 10MW in North Scotland
Hybrid Plant – e.g. combination of Generating Units plus PPM provided that the total Exports are equal to or less than 50MW in England and Wales, 30MW in South Scotland and 10MW in North Scotland
In addition, if there are different Parties responsible for the Import to or Export from one of the above configurations of Primary BM Units, the Import to the Plant and Apparatus can be registered in one Primary BM Unit and the Exports from the Plant and Apparatus in another Primary BM Unit as a standard configuration.
Any of the above configurations of Plant and Apparatus with associated Metering Systems registered in CMRS may have back up assets with Metering Systems registered in SMRS provided that the Registered Capacity of the Boundary Point with Metering systems registered in SMRS is less than or equal to 415V.
Configurations of Plant and Apparatus not Permissible (unless agreed by the ISG)
Any configuration of Plant and Apparatus either not on the list of permissible configurations above or not meeting the criteria for a Standard Primary BM Unit is not automatically permissible as a single Primary BM Unit in the BSC. Parties may apply for a Non-Standard Primary BM Unit for any configuration of Plant and Apparatus that cannot be registered as a single Primary BM Unit, including those below.
Open Cycle Gas Turbines with two or more generating Units (OCGTs) (including CCGT conversions);
Two or more onshore PPMs controlled as a single entity;
Combination of Generating Units or PPMs or hybrid Plant connected to the Total System, with total Exports greater than 50MW in England and Wales, 30MW in South Scotland and 10MW in North Scotland;
Directly Connected Premises at more than one Boundary Point with total Imports greater than 50MW in England and Wales, 30MW in South Scotland and 10MW in North Scotland;
Back-up assets for a CVA Primary BM Unit registered in SVA of more than 415V.
Registration of Directly Connected and Embedded Primary BM Units
What is a Directly Connected Primary BM Unit?
Directly Connected Primary BM Units comprise of equipment directly connected to the Transmission System with a Bilateral Connection Agreement (BCA) with the NETSO. They are usually Generation Units but can also be large demand sites.
What is an Embedded Primary BM Unit?
Embedded Primary BM Units comprise of equipment registered in CVA that is connected to a Distribution Network. They are Generation Units and can include the imports relating to these sites, but large embedded demand sites without any generation cannot be registered as a CVA Embedded Primary BM Unit.
Assets that have a Bilateral Embedded Generation Agreement (BEGA), with the NETSO normally must be registered in the BSC as CVA Primary BM Unit(s) as a condition of the BEGA.
How long does it take to register a Directly Connected or Embedded BM Unit?
The registration of a Standard BM Unit has a 30 Working Day lead time and a Non-Standard BM Unit has a 60 Working Day lead time within BSC Systems. We therefore recommend that you start the process about three to four months before your earliest energisation date.
How do I register a Directly Connected or Embedded BM Unit during Market Entry?
To register the BM Unit please log into the Elexon Kinnect Customer solution:
Click on Register Assets and you will be directed to the manage assets page
Click on the plus button on the right hand side to add a new asset
Click on Balancing Mechanism Unit
Complete the mandatory starred fields:
BM Unit Id is of the form T_[NGC BM Unit Id] for directly connected BM Units or E_[NGC BM Unit Id] for embedded BM Units. If you do not have an NGC BM Unit Id, please create an ID that is relevant to your site (maximum character length 11 including T_ or E_).
The FPN Flag will be ‘Yes’ if you are trading in the Balancing Mechanism and have a NGC BM Unit ID. Otherwise it is no.
The Effective From Date should be at least 30 Working Days in the future for Standard BM Units or 60 Working Days in the future for Non-Standard BM Units.
You need to enter the Generation Capacity (GC) and Demand Capacity (DC) of each Primary BM Unit, as well as the Final Physical Notification (FPN) Flag. You need to enter the GC and DC as the Maximum Positive QMij, and Maximum Negative QMij which will be doubled in the system to give the GC and the DC.
If the Primary BM Unit will be Exempt Export, select Exempt Export and explain why it is exempt Export. Also select the BM Unit Production / Consumption Flag. Note that this field will appear under the BM Unit Type field when you select Exempt Export and you will need to scroll up the page to complete it.
the location of the Metering Equipment, in particular the Settlement current and voltage transformers (CTs/VTs) and CT/VT ratios;
any existing Boundary Points and/ or any System Connection Points at or near the proposed Boundary Point(s); and
any back up SVA connection and interlocking arrangements.
If you have indicated that the
BM Unit configuration is Non-Standard, please complete form
BSCP15/4.13 to explain why you believe that the
BM Unit should be registered as a Non-Standard
BM Unit.
How do I register a Directly Connected or Embedded BM Unit after Market Entry?
If you need to register more BMUs after Market Entry then the process is similar to the above, except that you will need to click on the ‘My Assets’ tile from the home page and then click on the ‘Manage Assets’ tile to view your existing BMUs and create new ones.
If you are unable to complete the
BM Unit application through the Elexon Kinnect
Customer solution, please complete this information in form
BSCP15/4.1 and submit it via Elexon Support:
https://support.elexon.co.uk/csm. If the
BM Unit is Exempt
Export please also complete form
BSCP15/4.5A.
What else is needed before the BM Unit can go live?
BSCP20/4.1: This form details the CVA Metering System Identifier (MSID) being registered for the Primary BM Unit, and the CVA Meter Operator (CVA MOA) appointed by you . You can reserve a CVA MSID for the site in advance by emailing the CRA (neta@imserv.com), stating the Name, whether it is Transmission or Distribution connected, and its location (England and Wales, North of Scotland, or South of Scotland). The CRA will provide details of the CVA MSID. For a Distribution connected Metering System, the LDSO may determine that a separate Line Loss Factor (LLF) is required to be applied to the Export and the Import flows; in this case, two CVA MSIDs would be required. The BSCP20/4.1 forms need to be sent by the Registrant to the CRA (neta@imserv.com) by 20 WD prior to the EFD.
BSCP75/4.2: This form details the Aggregation Rules for the Primary BM Unit(s). For an embedded Primary BM Unit, then the rule will also need to include reference to a LLF. Guidance on writing Aggregation Rules can be found in the Aggregation Rules Guidance. Note that the identifiers in the Aggregation Rules need to match those in the Meter Technical Details. The BCP75/4.2 form needs to be sent by the Registrant to the CRA (neta@imserv.com) by 20 WD prior to the EFD.
Metering Equipment should be compliant with the relevant
Code of Practice at the time of first registration for
Settlement purposes, however should any aspect of your
Metering System be unavoidably non-compliant, there is a process for making an application for a
Metering Dispensation from the relevant
Code of Practice via
BSCP32 . Elexon can advise prior to submission and we recommend that the signed
BSCP32/4.1 form and any supporting documentation is submitted at least 14 weeks prior to the EFD.
Metering Dispensations should be sent to
dispensations@elexon.co.uk. Note that
Panel Committees may approve, reject or defer a decision on a
Metering Dispensation so the ideal situation is for all metering to be compliant with the relevant
Code of Practice. Further information on the
Metering Dispensation process can be found on the
Metering Dispensations page of the
BSC Website.
BSCP20/4.3 registers the
Meter Technical Details (MTDs) related to the
Metering Systems of your
Primary BM Unit(s), and is usually submitted by the
Meter Operator Agent (MOA) to the
CDCA2 (
neta@imserv.com) at least 16
Working Days before the EFD. It can also be submitted by the
Registrant of the
Metering System.
Your CVA MOA must Commission and Prove the
Metering System in accordance with
Code of Practice 4 and
BSCP02 . This must be completed at least 8
Working Days before the EFD.
BSCP25/5.1 is required for Directly Connected
BM Units and registers the
Transmission System Boundary Point. It is submitted by the NETSO. Elexon will liaise with the NETSO for the submission of this information.
Embedded
Primary BM Units need CVA LLFs for use in their
Aggregation Rules. The relevant
Licensed Distribution System Operator (
LDSO) is responsible for submitting them within the LLF timescales in
BSCP128. Please ask the
LDSO to submit CVA LLFs (as opposed to SVA LLFs) for the site and to cancel any SVA MPANs for the Distribution connection that they may have allocated, as the CVA
MSID will be used instead.
For an embedded (distribution connected) Primary BM Unit, the relevant LDSO will need to update the relevant GSP Group Take Aggregation Rules. These are prepared by the Central Data Collection Agent (CDCA) and signed off by the LDSO. Elexon will manage this process as GSP Group Take Aggregation Rules need to be updated in the order that assets are added to or removed from a GSP Group.
Some
Offshore and onshore
Power Park Modules (PPM) can be moved between
Primary BM Units. You can set the relevant
Primary BM Units up in a
Switching Group, and opt to run the relevant PPM in any of the
Primary BM Units within that
Switching Group. To set this up, you must enter the relevant details in the Elexon Kinnect
Customer solution or in the table at the end of the
BSCP15/4.1 form as well as submitting the applicable
Aggregation Rules (
BSCP75) for all the possible running configurations when you are registering the
Aggregation Rules.
When all the above steps have been completed and checked by Elexon, Elexon will issue an approval to energise the Transmission System Boundary Point to the NETSO (for directly connected Primary BM Units), or an approval to energise the Primary BM Unit connection to the relevant LDSO (for Embedded Primary BM Units). This will be for the date you requested or a later date if that is not achievable. Please keep Elexon informed of changes to your intended energisation date.
All registration requirements should be completed in time to allow the approval to energise email to be issued at least 4 WD before your Effective From Date.
The Effective From Date given in the approval to energise email is the earliest date that you can physically energise your connection to the Transmission / Distribution System and this is the date that the CDCA will begin to collect Metered Data from your site. It does not matter if the physical energisation date of your equipment is after the Effective From Date quoted in the approval to energise email, but it must not be before.
Registration of Interconnector Primary BM Units
What is an Interconnector Primary BM Unit?
Interconnector Primary BM Units allow Parties to trade over a particular Interconnector, and always come in pairs. One of the Primary BM Units is for electricity entering the System over the Interconnector (Production), and the other is for electricity being taken off the System (Consumption). Each Interconnector has many pairs of these Primary BM Units, one pair for each Party who has registered to use it.
Interconnector Primary BM Units work differently to other
Primary BM Units because the
electricity is not metered for each
Party’s
Primary BM Units, but at the
Interconnector Boundary. The
Interconnector Administrator submits the deemed Primary
BM Unit Metered Volume on the
Party’s behalf. The difference between the
Interconnector Metered Volume and the Primary
BM Unit Metered Volumes (deemed to have been delivered) is attributed to the
Interconnector Error Administrator. For more information about
Interconnectors please refer to the
Interconnector Trading Guidance.
How do I register an Interconnector BM Unit during Market Entry?
To register the BM Unit please log into the Elexon Kinnect Customer solution:
Click on Register Assets and you will be directed to the manage assets page
Click on the plus button on the right hand side to add a new asset
Click on Balancing Mechanism Unit
Complete the mandatory starred fields:
BM Unit Id is of the form I_[NGC BM Unit Id]
The FPN Flag will be ‘Yes’
The Effective From Date should be at least 30 Working Days in the future.
Choose the Interconnector that the BM Unit relates to.
For the Production Primary BM Unit (i.e. electricity flowing into the GB Transmission System), enter a Maximum Positive QMij, a zero in the Maximum Negative QMij DC and a ‘P’ for Production/Consumption (P/C) Flag. The Maximum Positive QMij will be doubled in the system to give the GC.
For the Consumption Primary BM Unit (i.e. electricity flowing from the GB Transmission System), enter a zero in the Maximum Positive QMij, a Maximum Negative QMij and a ‘C’ for the Flag. The Maximum Negative QMij will be doubled in the system to give the DC.
How do I register an Interconnector BM Unit after Market Entry
If you need to register more BMUs after Market Entry then the process is similar to the above, except that you will need to click on the ‘My Assets’ tile from the home page and then click on the ‘Manage Assets’ tile to view your existing BMUs and create new ones.
If you are unable to complete the
BM Unit application through the Elexon Kinnect
Customer solution, please complete this information in form
BSCP15/4.1 and submit it via Elexon Support:
https://support.elexon.co.uk/csm.
Registration of Supplier Primary BM Units (2_Primary BM Units)
What is a Supplier Primary BM Unit?
Supplier Primary BM Units measure the amount of electricity supplied by Suppliers. Due to the high number of Supplier Meters that exist, individually identifying them all is unfeasible. Instead, all the Meters for a particular Supplier ID in a specific GSP Group are grouped into one Supplier Primary BM Unit.
When you sign up as a Supplier, you will be allocated 14 ‘Base’ Supply Primary BM Units, one for each GSP Group, even if you do not plan to use them all. All your supply and SVA registered embedded generation in a particular GSP Group will by default be allocated to the relevant Base Primary BM Unit.
You can register ‘Additional’ Primary BM Units for particular asset or grouping of Customers within a GSP Group.
How do I register Base Supplier BM Units?
As part of the Elexon Market Entry Process, you will be given access to the Elexon Kinnect Customer solution. You will need to register the Supplier Role, by accessing the register market role tile and creating a new role of Supplier. Your 14 Base Supplier Primary BM Units will be automatically created by the Customer Solution as part of registering your role of Supplier.
For each of your Base BM Units, you then need to enter various BM Unit Details such as the Effective From Date and the Maximum Positive QMij, and Maximum Negative QMij which will be doubled in the system to give the Generation Capacity (GC) and the Demand Capacity (DC).
In order to add the BM Unit details you will need to click on the register assets page within the home screen. This will take you to the manage assets page where you will see the 14 Base BMUs that have been created. You can then access each BMU and click on the manage asset details button which will take you to the form to complete (see screenshots below):
Click on each
Asset ID:
Click on the manage asset details button in the bottom left:
Click on the plus button on the manage
BM Unit details screen:
Complete the relevant information on the register asset detail page:
If you are unable to update the complete the Maximum Positive QMij, and Maximum Negative QMij through the Elexon Kinnect
Customer solution, please complete this information in form
BSCP15/4.1 and submit it via Elexon Support:
https://support.elexon.co.uk/csm.
The
Supplier Role, and your
Market Participant Identifier (MPID) will need to be registered in both the
Central Registration Agent (CRA) Database and the
Market Domain Data (MDD) Database. The
Customer Solution registers your role in CRA, but to register the
Supplier details and the
Base BM Units in the MDD Database, please complete
MDD Change Request form F509/01 &
Entity Forms 1, 45 & 61. Please Email these Forms to
Mddc@elexon.co.uk. The usual EFD is the next available MDD Go live Date as per the
MDD Release Schedule
How do I register an Additional Supplier BM Unit?
To register as an Additional BM Unit, you need to register it in the Central Registration Agent (CRA) Database and the Market Domain Data (MDD) Database. You cannot register an Additional BM Unit until you have registered your 14 Supplier Base BM Units.
To register the BM Unit in CRA please log into the Elexon Kinnect Customer solution:
Click on My Assets
Click on Manage Assets
Click on the plus button on the right hand side to add a new asset
Click on Balancing Mechanism Unit
Complete the mandatory starred fields:
BM Unit Id is of the form 2__XMPIDnnn, where _X is the GSP Group, MPID is your four letter MPID and nnn is the next available number for an Additional BM Unit registered to your MPID in the GSP Group, starting 001 or a number of your choosing.
The Effective From Date should be at least 15 Working Days in the future and on or after the Effective From Date of the BM Unit in Market Domain Data.
If you are participating in the Balancing Mechanism and have an NGC BM Unit Id, then set the FPN Flag to ‘yes’ and add the NCG BM Unit Id. Otherwise leave the FPN Flag as ‘No’
You need to enter the Generation Capacity (GC) and Demand Capacity (DC) of each Primary BM Unit, as well as the Final Physical Notification (FPN) Flag. You need to enter this as the Maximum Positive QMij, and Maximum Negative QMij which will be doubled in the system to give the GC and the DC.
Enter a Baseline status of ‘Yes’ if Settlement Expected Volumes should be used instead of PNs in the calculations or ‘No’ if the BM Unit does not submit PNs or PNs should be used in the calculations.
If the Additional Primary BM Unit will be Exempt Export, select Exempt Export and explain why it is exempt Export. Also select the BM Unit Production / Consumption Flag. Note that this field will appear under the BM Unit Type field when you select Exempt Export and you will need to scroll up the page to complete it.
Note that if a Primary Supplier BM Unit is registered as an Exempt Export BM Unit, it can only contain the Exemptable Generating Plant for which it is being registered, it cannot contain additional generation or demand. i.e. it must satisfy the conditions for a Standard Primary BM Unit or be approved by the Panel as a Non-Standard Primary BM Unit as set out in the section above, as if it were an embedded Primary BM Unit.
A Base Primary BM Unit can have an Exempt Export status, if it contains a single Exemptable Generating Plant. A Party that wishes to flag a Base Primary BM Unit as Exempt Export Status needs to ensure that they do not allocate any other Generation or Demand to that Primary BM Unit.
If you are unable to complete the application through the Elexon Kinnect
Customer solution, please complete this information on pages 1 and 2 of form
BSCP15/4.1 and submit it via Elexon Support:
https://support.elexon.co.uk/csm. If the
BM Unit is Exempt
Export please also complete form
BSCP15/4.9A.
Is there anything else I need to do?
You need to allocate SVA
MSIDs to the Additional BMU in your own systems. You also need to instruct your appointed HHDA to transfer the relevant SVA
MSIDs out of the
Base BM Unit into the
Additional BM Unit by you as a
Supplier sending a D0297 “Notification of
BM Unit Allocation data flow to the appointed HHDA, in accordance with the process in section 3.5 of
BSC Procedure BSCP503 (‘Half Hourly Data Aggregation for SVA Metering Systems registered in SMRS’). Your HHDA should confirm successful allocation by sending back a D0294 “Confirmation of
BM Unit Allocation” Data flow.
Are there any other options?
If you wish to register an Additional
Primary BM Unit in every
GSP Group you may wish to register an additional
Market Participant Identifier (MPID) under your
Trading Party Id instead . This would have the effect of creating another set of 14
Supplier Primary BM Units under the new MPID and which would carry no extra BSC Charges. Creating a set of 14
Additional BM Units, one in each
GSP Group would cost £840 in BSC Charges (see the
Schedule of Main and SVA Specified Charges). If registering an additional MPID you should consider the impact that splitting your portfolio may have on your reporting e.g. DTN, PARMs.
You will need to register the additional MPID in CRA and MDD. To register an additional MPID in CRA you can log into the Elexon Kinnect Customer solution and from the homepage click on the ‘My roles’ tile. Click on the plus button in the top right hand corner to register a new Supplier role with a new MPID.
Your 14 Base Supplier Primary BM Units for the new MPID will be automatically created by the Customer Solution as part of registering your role of Supplier.
For each of your Base BM Units, you then need to enter various BM Unit Details such as the Effective From Date and the Maximum Positive QMij, and Maximum Negative QMij which will be doubled in the system to give the Generation Capacity (GC) and the Demand Capacity (DC)..
In order to add the BM Unit details you will need to click on the register assets page within the home screen. This will take you to the manage assets page where you will see the 14 Base BMUs that have been created. You can then access each BMU and click on the manage asset details button which will take you to the form to complete (see screenshots below):
Click on the manage asset details button in the bottom left:
Click on the plus button on the manage BM Unit details screen:
Complete the relevant information on the register asset detail page:
Alternatively the Additional MPID can be registered using a
BSCP65/05. Also, If you are unable to update the complete the Maximum Positive QMij, and Maximum Negative QMij through the Elexon Kinnect
Customer solution, please complete this information in form
BSCP15/4.1 and submit it via Elexon Support:
https://support.elexon.co.uk/csm.
Note that if you wish to participate in the Balancing Mechanism, the NETSO may require you to register Additional Supplier BM Units as opposed to registering an additional MPID with Base Supplier BM Unite
Registration of Supplier Additional Primary BM Units (C_ BM Units) for EMR Assets
Suppliers can register
Additional BM Units for Contract For Difference (CfD)
Assets using the registration of Additional
Supplier BM Units process described above. Please refer to the
Registration of Primary BM Units for EMR guidance for naming conventions.
Electricity Market Reform Settlement Limited (EMRS) will register a set of Supplier Additional BM Units for every interested Supplier when a new SVA registered CfD Assets is due to go live so that a Supplier has a BM Unit for the Asset should they obtain a contract for that Asset. As there are a large number of ‘Empty’ Additional Supplier BM Units for EMR Assets, there is no charge associated with these BM Units.
Registration of Secondary BM Units (V_BM Units)
What is a Secondary BM Unit?
Secondary BM Units record the amount of Balancing Energy provided by VLPs or AMVLPs to the NETSO.
How do I register a Secondary BM Unit during Market Entry?
To register the BM Unit please log into the Elexon Kinnect Customer solution.
Click on Register Assets and you will be directed to the manage assets page
Click on the plus button on the right hand side to add a new asset
Click on Balancing Mechanism Unit
Complete the mandatory starred fields:
BM Unit Id is of the form V__XPPPPNNN, where X is the relevant GSP Group letter, PPPP is your four-letter Identifier (this may be the same as your Market Participant Identifier (MPID) if you are also a Supplier) and NNN are numbered sequentially, i.e. 001, 002 etc, for your identifier within each GSP Group or a number of your choosing.
The FPN Flag will be ‘Yes’
The Effective From Date should be at least 15 Working Days in the future.
Enter a Production/Consumption (P/C) Flag of either P or C. This is only relevant for Parties who also have other Party roles under the BSC. If you are a VLP only, you must enter a C. If not sure, then enter a C.
Enter a Baseline status of ‘Yes’ if Settlement Expected Volumes should be used instead of PNs in the calculations or ‘No’ if the BM Unit does not submit PNs or PNs should be used in the calculations.
How do I register a Secondary BM Unit after Market Entry?
If you need to register more BMUs after Market Entry then the process is similar to the above, except that you will need to click on the ‘My Assets’ tile from the home page and then click on the ‘Manage Assets’ tile to view your existing BMUs and create new ones.
If you are unable to complete the
BM Unit application through the Elexon Kinnect
Customer solution, please complete this information in form
BSCP15/4.14 and submit it via Elexon Support:

Electricity Market Reform (EMR)
If you have a
Contract for Difference or Capacity Market Contract, this may require you to set up your
Primary BM Units in a particular configuration. The
EMR Website lists all the latest news and industry information on EMR. You can also contact the team directly at
contact@emrsettlement.co.uk.
Metered Volume Reallocation Notifications (MVRNs)
MVRNs are used to notify the BSC central systems that the energy flowing to or from a particular Primary BM Unit is to be allocated to one or more different Party’s Energy Accounts for the purposes of Energy Imbalance calculations.
To set up a
MVRNA Authorisation, you (the
Lead Party), the relevant Notification Agent (
MVRNA) and the
Subsidiary Party each need to complete the relevant parts of a
BSCP71/02 Form and send to
neta@imserv.com, showing:
The relevant MVRNA i.e. the person responsible for submitting the MVRNs to central systems
The Lead Party for the Primary BM Unit i.e. the BSC Party FROM whom the metered volumes will be moved
The Subsidiary Party for the Primary BM Unit i.e. the BSC Party TO whom the metered volumes will be moved
The Lead Party Energy Account. This must be either Production or Consumption and must be the same as the Subsidiary Party Energy Account, and must match the Production/Consumption status of the Primary BM Unit
The Subsidiary Party Energy Account. This must be either Production or Consumption and must be the same as the Lead Party Energy Account, and must match the Production/Consumption status of the Primary BM Unit
The Primary BM Unit Identifier
The required Effective From Date
Note that you can only set up a MVRNA from a Production BM Unit to another BSC Party’s Production Account OR a Consumption BM Unit to another BSC Party’s Consumption Account. This should also be taken into consideration if you are also applying for Exempt Export status, as you can choose and fix the Production / Consumption Flag of the BM Unit.
Please note that until Elexon has issued the Approval to Energise email, your Primary BM Unit and the MVRNA Authorisation will not be registered in the BSC central systems. Your MVRNA will not be issued with the MVRNA Authorisation Identifier and unique MVRNA Key until after Elexon has issued the Approval to Energise email.
Please note that if the Approval to Energise Email is issued at least 2 WD before the Primary BM Unit EFD, then the MVRNA Authorisation Identifier and unique MVRNA Key can be issued to the MVRNA at latest 1 WD before the Primary BM Unit EFD, allowing the MVRNA to submit MVRNs from Settlement Period (SP) 1 of the Primary BM Unit EFD.
Primary BM Unit T_ELEX-1 has an EFD of 01/12/16 (a Thursday)
Elexon issue Approval to Energise Email before 14:00 29/11/16 (a Tuesday)
On 29/11/16, Primary BM Unit T_ELEX-1 entered into the central systems with an EFD of 01/12/16
On 29/11/16, Primary BM Unit T_ELEX-1 now entered into the central systems, allowing a MVRNA Authorisation for it to be created with an EFD of the next day, i.e. 30/11/16 (a Wednesday). MVRNA Authorisation Identifier and unique MVRNA Key then issued to MVRNA with an EFD of 30/11/16. (MVRNA Authorisation not valid before 30/11/16 so central System would reject any MVRN submission prior to that date)
On 30/11/16, MVRNA can submit MVRNs for Primary BM Unit T_ELEX-1 from at earliest SP1 of the Primary BM Unit EFD i.e. 01/12/16 (Primary BM Unit not valid before 01/12/16 so central System would reject any MVRN submission prior to that date)
Please note that if the Approval to Energise Email is not issued until 1 WD before the Primary BM Unit EFD, then the MVRNA Authorisation Identifier and unique MVRNA Key can be issued to the MVRNA, but the MVRNA Authorisation will not be valid until the same EFD as the Primary BM Unit, meaning that the MVRNA will not be able to submit MVRNs until at earliest midnight of the Primary BM Unit EFD, and that there will be a one Settlement Period (SP) gap in the MVRN (for SP 1), as Gate Closure will have passed for SP 1. You as the Lead Party may need to address this issue.
Primary BM Unit T_ELEX-1 has an EFD of 01/12/16 (a Thursday)
Elexon issue Approval to Energise Email before 14:00 30/11/16 (a Wednesday)
On 30/11/16, Primary BM Unit T_ELEX-1 entered into the central systems with an EFD of 01/12/16
On 30/11/16, Primary BM Unit T_ELEX-1 now entered into the central systems , allowing a MVRNA Authorisation for it to be created with an EFD of the next day, i.e. 01/12/16 (a Thursday). MVRNA Authorisation Identifier and unique MVRNA Key issued to MVRNA with an EFD of 01/12/16. (MVRNA Authorisation not valid before 01/12/16 so central System would reject any MVRN submission prior to that date)
On 01/12/16, MVRNA can, from at earliest midnight, submit MVRNs for Primary BM Unit T_ELEX-1, however the earliest SP will be SP2 on 01/12/16 (Primary BM Unit not valid before 01/12/16, and Gate Closure has passed for SP 1, so central System would reject any MVRN submission prior to that SP)
By default, all directly connected and embedded Primary BM Units are sole Trading Units. If your site consists of more than one Primary BM Unit then you may wish to set up a Trading Unit for the overall site. Being a Trading Unit allows all the Primary BM Units to be treated the same for:
There are 14 Base Trading Units, one for each GSP Group. By default, all Supplier and SVA Exempt Export Primary BM Units will be added to the Base Trading Unit. If you do not want your SVA Exempt Export Primary BM Unit to be part of the relevant Base Trading Unit you need to apply for it to be part of a different Trading Unit.
You can apply for a
Trading Unit via the Elexon Kinnect
Customer Solution. Further information on
Trading Units can be found on the
Trading Units Section of the
BSC Website and in
BSCP31.
