This interactive process map will provide details on the activities and interactions you will have with EMRS as a Capacity Provider to support you in participating in the CM scheme for EMR. When you click on each stage this will provide you with the requirements applicable for your role, tasks to be completed and relevant supporting information.

1. Credit Cover

Applicants are required to lodge Credit Cover if they receive a notice from the Delivery Body confirming pre-qualification of their Capacity Market Unit(s) is conditional on providing Credit Cover.

Do I need to register with EMRS?

You do not have to register to successfully lodge Credit Cover. Instead, once you have lodged, contact the Service Desk stating the below:

  • CMU ID(s)
  • Auction
  • Amount
  • Format (cash or Letter of Credit)
  • Date it will be received in bank (if cash)
  • Letter of Credit (LoC) ID (if LoC)
  • A copy of the SWIFT message sent to ESC’s bankers (if LoC)

If lodging for multiple CMU’s in one LoC or bank transfer, please confirm the monetary break down.

What form of Credit Cover can be accepted?

The Credit Cover can be lodged in the form of cash, Letter of Credit (LoC) or a combination of both. The bank details and latest LoC template can be found in WP35- CM Applicant /Capacity Provider Credit Cover Process.

Please note when any changes are required to existing Letter of Credits that are in place, Capacity Provider are recommended to issue an amendment to a Letter of Credit rather than issuing a new Letter of Credit.

How long does a Letter of Credit need to be valid for?

LoC should be valid for a minimum of 6 months from date of issue. If Credit Cover is required past the expiry date we will contact you requesting that you extend your Letter of Credit but please note it is the Applicant/Capacity Providers responsibility to ensure valid Credit Cover is lodged.

Return of Credit Cover

Return of Credit Cover can be requested once Delivery Body has confirmed the Credit Cover value of the CMU has decreased. EMRS are only able to process the Credit Cover return once Delivery Body has communicated the decrease of Credit Cover value for the CMU to us.

If you have queries regarding the Credit Cover requirement please contact Delivery Body.

How do I request the return of my Credit Cover and how long does it take?

The Credit Cover return process can be different depending on whether the Applicant has registered with EMRS (being granted an EMR Party ID) or not.

If you have previously registered with EMRS, you need to contact the Service Desk with below information:

  • CMU ID(s)
  • Amount (monetary break down for multiple CMUs)
  • Format (cash or LoC)
  • Bank details (if cash) – this must match the bank details we have on recorded for you
  • LoC ID (if LoC)

This request must come from a Primary Party Authority, Finance Authority or Credit Contact. To understand the privileges of each authority, please see G4 – EMR Settlement Authorisations.

If you haven’t registered with EMRS previously and wish to request the return of Credit Cover please contact the Service Desk:

  • If Credit Cover is lodged in Cash, please request and complete a Cash Credit Cover Return form.
  • If Credit Cover is lodged by LoC, please email your request to confirm the CMU ID, Amount, auction and LoC ID.
  • Please note that requests should be sent by the Delivery Body main contact.

Please do not ask your bank to amend or cancel a LoC before you have received authorisation from EMRS as these will be rejected.

Further information of Credit Cover return process can be found on WP35- CM Applicant /Capacity Provider Credit Cover Process.

2. Registering with EMRS

Registering with EMRS is required prior to the start of Delivery Year your agreement is awarded to enable Capacity Payment to be made to you. Failure to complete the registration process may result in Capacity Payments not being made on time.

If you are not registered with EMRS please use My EMRS. This is a digital solution removing the completion of manual forms and provides you with access to your registration details you have provided. The process steps are illustrated within WP22 – Applicant and Capacity Provider Registration.

We have produced a short video to illustrate the Registration process using My EMRS.

For additional support or guidance, we have published G25 – My EMRS Registration User Guide and About My EMRS contains useful FAQs.

You will need to complete the following registration details within My EMRS:

  • User Contact Details
  • Company Details
    • Company Registered Details (Name, Address, Company Number)
    • EMR Party ID
    • Where an EMR Party is a BSC Party, the EMR Party ID must match the Party’s BSC Party ID. For more information on BSC Party IDs please refer to the Elexon
  • Settlement Information
    • Primary Company Email Address (day to day correspondence gets sent here)
    • Interface method to be used in sending backing data (email or DTN)
  • Primary Bank Account
  • Credit Cover Return Account
  • Contact Details

Once these details are completed, you submit them for Approval by an Authorised Contact and then EMRS. We will keep you informed via email notification of successfully or unsuccessfully approval and when to access My EMRS if required.

Once authorised contacts are registered, they will also receive access to the EMRS Portal.

Amending registration details

You are able to amend your registration details at any time via using My EMRS and this is also detailed in WP22 – Applicant and Capacity Provider Registration. To amend your details please selecting ‘View/Amend Existing Party Details’. You can then select from the menu on the left-hand side on the area you will be amending:

  • User Contact Details
  • Company Details
  • Settlement Information
  • Primary Bank Account
  • Credit Cover Return Account
  • Contact Details

Once you have submitted your amendment, these will be received by EMRS to review and confirm if your updates have been approved or rejected by email.

Please note when Bank Account Details are amended these do need to be verified and EMRS will contact a relevant Authorised Contact (either a Primary Party Authority or a Finance Authority) to confirm bank details.

3. Metering Test

If, after completing the Delivery Body Metering Assessment process, a Metering Test is required for a Component within a CMU, a Capacity Provider needs to contact Service Desk to request one.

A Metering Statement, as per Schedule 6 of the Capacity Market (Amendment) Rules 2015, needs to be submitted for each Component that triggered a Metering Test. This must provide details of all Components making up the CMU.

All Metering Test and Metering Statement requests as well as any required metering information needs to be submitted to Service Desk before the deadline of each Delivery Year.

For more information, please refer to G1-Capacity Market Metering and G20-Metering Statement Guidance.

4. Metering Aggregation

Capacity Providers need to submit Metering Aggregation information for all CMUs with Capacity Agreements for the 2021/22 Delivery Year by 30 September 2021.

Metering Aggregation information is used as the basis for aggregating Metered Volumes in the EMR Settlement System to demonstrate you have delivered your Capacity Obligation during a Stress Event if no Metering Aggregation information available this could lead to Penalty Charges. This information also supports completing your Satisfactory Performance Days and Extended Performance (if applicable) obligations.

The rule is based on CMU components which are made up of an Approved Metering Configuration Solution. Each CMU is made up of one or more CMU components, which can be made up of one or more Metered Entities. The output of the EMR Aggregation Rule will be used to determine whether a CMU has met their Capacity Obligation.

This process is managed through the EMR Delivery Body Portal. Please be aware you must have the correct level of access rights in the EMR DB Portal to be able to both save and submit Metering Aggregation information for review. Until you have had an email notification from the EMR DB Portal confirming the Metering Aggregation information has been reviewed by EMRS (on behalf of ESC), the process has not yet been completed. You must log in to the EMR DB Portal and check all components have been approved.

To aid you in completing this process please read the Metering Aggregation Guidance. If you have any technical Metering queries please contact the EMRS Metering Team, [email protected] all other queries please contact EMR Delivery Body, [email protected].

WP25 – EMR Aggregation Rules provides further details and in Appendix 5 illustrates how a Capacity Provider CMU Aggregation Rules provides details on how the aggregation rule is developed.

5. Submit Metered Volumes

We encouraged Capacity Providers to submit metered volumes to EMRS on a daily or weekly basis. Capacity Providers can submit metered volumes via a number of sources:

  • Balancing and Settlement Code Company (BSCCo) Balancing Mechanism Units (BMU)
  • Supplier Settlement (Non-BMU) Capacity Providers will need to request that their Supplier(s) send a D0354 flow to the appointed Data Aggregator (DA). This will trigger the DA to send D0357 flows to EMRS.
  • Self-submission by the Capacity Provider or their appointed Data Collector (DC) Uses a defined CSV format to uploaded data into the EMR Settlement System via Secure File Transfer Protocol (SFTP) account with EMRS. Contact Service Desk to setup an SFTP account.

BMU and Supplier Settlement (Non-BMU) data is submitted in accordance with the BSC Settlement Calendar and this calendar is available on the Elexon Portal.

Capacity Providers using the Supplier Settlement (Non-BMU) metering pathway are responsible for the status of the data flow arrangements and should check on a periodic basis from start of the Delivery Year.

Note: If you change your Supplier this will result in the de-appointment of the Data Aggregator and a new relationship will be established through a D0354 flow from your new Supplier.

All Capacity Providers are encouraged to monitor their relevant data flows, as these must be in place to pass Satisfactory Performance Days and avoid suspension or termination. This validity of data flows will also assist in minimising any penalties incurred should a Stress Event occur.

Defined CSV format

For those who have selected self-submission by the Capacity Provider or their appointed Data Collector (DC) uses a defined CVS format to provide their Metered Data to EMRS.

The requirements and file format are available in WP195 – Capacity Market and CfD Metered Data and please refer to the following:

  • Appendix 1 – CSV File Requirements
  • Appendix 2 – CSV file format

Supporting information on Secure File Transfer Protocol (SFTP)

Account Creation

Capacity Providers who need an SFTP Account will need to contact the Service Desk to request a SFTP account and will need to confirm the following details:

  • EMR Party ID:
  • Capacity Provider ID:
  • SFTP Account Contact Name:
  • SFTP Account Contact Email:
  • SFTP Account Contact Mobile (password will be sent to):

Once your account has been created, EMRS will issue your login details and provide any supporting information.

SFTP Account Structure

You will only use the STEP001_IN, STEP001_OUT and STEP001_ARCHIVE, folders for the submissions of metered data.

  • STEP001_IN is where you will submit your metered data.
  • STEP001_OUT is where you will see your notifications.
  • STEP001_ARCHIVE is where you will see your archived notifications.

We encourage Capacity Providers to monitor the STEP001_OUT to identify if they have received the ‘Metered Data unsuccessfully loaded Notification’.

SFTP Notifications

Capacity Providers receive the below notifications when they submit their metered data:

  • Metered Data Received Notification
  • Metered Data Successfully Loaded Notification
  • Metered Data Unsuccessfully Loaded Notification

As noted above Capacity Providers are encouraged to monitor the STEP001_OUT to identify if they have received the ‘Metered Data Unsuccessfully Loaded Notification’.

If Capacity Provider’s need further assistance with determining why their submitted CSV Metered Data file has unsuccessfully loaded, please contact the Service Desk and provide the following details:

  • Metered Data file name:
  • Date csv file uploaded to SFTP folder:
  • CM Units affected:

Forgotten SFTP Password

If you have forgotten your SFTP password, please contact the Service Desk who will assist with your query.

6. Delivery Year Starts

Prior to the start of a Delivery Year we’d like to inform Capacity Providers of the following:

  • Amending registration details with EMRS
  • Submission of Metered Volumes
  • Volume Reallocation
  • Receiving Capacity Provider Payments

These are areas that the EMR Delivery Body (DB) would like to highlight:

  • Secondary Trading with Delivery Body
  • Register for Volume Reallocation with the Delivery Body
  • Completing Satisfactory Performance Days (SPD) with Delivery Body
  • Stress Event – Capacity Market Warnings

7. Monthly Capacity Payment

EMRS manages Capacity Provider payments on behalf of Electricity Settlements Company (ESC). Capacity Providers will be issued with a Credit Note on the 28th Working Day following the end of the relevant Delivery Month. The credit notes and associated settlement files will be emailed to the company email addresses (the EMRS Portal is an additional channel for assessing settlement files) and payments are made to the bank account details as specified on the registration form validated by EMRS.

G17-Capacity Provider Payments provides further details about these payments.

Key Figures for Payments confirms the Monthly Weighting Factor.

EMRS Settlement Calendar provides a schedule of when payments for Capacity Providers will be invoiced, when payment is due, and if applicable, the Settlement Date and the Settlement Run.

8. Stress Event

A System Stress Event is defined in the Capacity Market Rules and is where the System Operator has instructed (involuntary) load reduction to maintain the security of the transmission system in the event of a shortage of generation to meet demand.

If a System Stress Event occurs after a Capacity Market Warning, Capacity Providers will be required to deliver their Adjusted Load Following Capacity Obligation (ALFCO).

Capacity Market Warnings

Are you registered to receive Capacity Market Notices? If you aren’t please register to receive GB Electricity Capacity Market Notices. The website will display all electricity Capacity Market Notices issued by National Grid. The site also provides frequently answered questions.

Volume Reallocation

After a System Stress Event has occurred, Capacity Providers may use Volume Reallocation if they have under or over-delivered compared to their Capacity Obligation. The process involves each participating CMUs to submit Capacity Market Volume Reallocation Notification (CMVRN) to EMRS who validate the CMVRN and volume reallocate.

WP48 – Volume Reallocation details the process and timescales associated to this process.

The Capacity Volume Register will be published on the Settlement Data page from 10th to 19th Working Day inclusive after the end of the month in which a System Stress Event occurs.

9. Penalty and Over Delivery Payments

Capacity Provider Penalty

These are financial penalties imposed on Capacity Providers who fail to meet their Capacity Obligations during a System Stress Event. Penalties are related to a Capacity Provider’s Capacity Payments and are capped at 100% of a Capacity Provider’s annual Capacity Payment with respect to a Capacity Market Unit (CMU), and at 200% of the CMU’s Capacity Payment for any individual month.

Over Delivery Payments

This is a payment made to a Capacity Provider that has delivered more than its Capacity Obligation during a System Stress Event. This payment is funded by the Penalties collected. Therefore the payment is calculated and made at the end of the Delivery Year once all Penalties have been received.

G17-Capacity Provider Payments provides further details about these payments.
