Becoming an Interconnector Administrator or Interconnector Error Administrator

This page lists and details the step-by-step process of becoming a Interconnector Administrator (IA) or Interconnector Error Administration (IEA). You will also learn about what qualifications are needed, the relevant costs and charges and any other information you may need to know.

What is an Interconnector Administrator?

The Interconnected System Operator (ISO) can appoint a different Party to be the IA and the IEA.

Interconnector Administrator

IAs are responsible for determining and submitting Interconnector BM Unit Metered Volumes on the Interconnector User’s behalf into Settlement for each
Settlement Period.

Interconnector Error Administrator

IEAs are allocated any difference between the actual Metered Volume and the aggregate position of all Interconnector User’s BM Unit Deemed Metered Volume (deemed to have been delivered) as notified by the IA.

Qualifications needed

In order to qualify as an Interconnector Administrator you will need to obtain the following qualifications:

The CVA Qualification is needed to prove that IAs and IEAs have the ability to send certain Communications to BSC Agents and ensure that certain communications are received. 

Waiver testing

You can waiver testing if you were to reach an agreement with an existing BSC party to use their already Qualified system. You can only apply for the waiver if the Supporting Participant you intend to use is Qualified in the same role as the Qualifying participant, as stated in BSCP70.

We would require a signed letter from the system owner and then you would be able to waiver testing on basis that the system was already tested when they went through Market Entry.

Costs

Interconnector Administrators or Interconnector Error Administrators acceding to the BSC must pay a £500 accession fee which covers the administrative costs of entering the market.

Once acceded, a flat monthly fee of £250 + VAT applies. This is known as a base monthly charge. 

How to become an Interconnector Administrator or Interconnector Error Administrator

You will need to go through various steps in order to register as a Interconnector Administrator or Interconnector Error Administrator. The diagram below lists all the tasks required.

Within the individual steps there are forms that need to be completed and details about financial transactions that need to take place.

Accession to the BSC

Accession to the BSC

The first stage of the market entry process is to become a BSC Party. This is done by signing the BSC Accession agreement, which is a contract between Elexon and the applicant. On signing the Accession Agreement the applicant is agreeing to abide by the rules and obligations set out within the BSC itself. Applicants must also pay a one off £500 application fee and be aware that on becoming a BSC Party, VLPs start paying the monthly membership fees of £125. Section A of the BSC lists the requirements you will need to fulfil to become a BSC Party.

What do I need to do?

Complete and sign an original copy of the BSC Accession Agreement. The agreement should be signed by the registered company director but not dated. Once we receive the agreements we will date and countersign them before returning one back to you.

Send the signed agreements to: [email protected].

Complete the Accession Form and send to Market Entry ([email protected]). This is to provide us with the details required to support you through the Market Entry process.

Send the £500 Application Fee – This can be paid by Cheque/BACS or CHAPS. BACS/CHAPS payments can be made using Elexon’s details as follows:

Account Name: Elexon Ltd
Account Number: 60115819
Sort Code: 20-00-00
Bank: Barclays Bank Plc

Please note that the above bank account is for Elexon charges only and is separate to the two bank accounts used by the Funds Administration Agent (FAA) for Trading Charges and Credit Cover. For more information on Elexon charges please see the BSC Costs & Charges webpage.

Order comms lines

Order comms lines

As a party operating within the BSC arrangements you will need to be able to send and receive communications to and from Elexon and the BSC Agent systems.

Communication methods

Some communications are manual (via fax, post and email) but most are sent via electronic data flows. The electronic data flows are sent and received via 2 communication methods, the High Grade Service and the Low Grade Service.

The High Grade Service

This provides access to all services and data through private network communication. For the BMRA service, the High Grade Services provides the capability for 24 hours a day, 7 days a week near real time information to be ‘pushed’ to the service users.

Users of the High Grade service can access this data either through browser screens (using Service Provider supplied applets to refresh the screens on receipt of updates), or through a defined programmatic interface (using TIBCO software) (BMRS data only).

The Low Grade Service

This provides access to all services and data through the public internet, with consequently no guarantees on access times or availability. The Low Grade Service provides access to BMRA data through a browser, but without the automatic refresh, the users are responsible for ‘pulling’ the data for screen based access and file downloads.

How much does it cost and how long does it take to order?

The Low Grade Service is free of charge for all Parties and takes Elexon around 5WDs to process your request. For more information on what is required please look at the Communications Requirement Document.

The charges for the High Grade Service depend on the type of line you require and whether you require a disaster recovery line and TIBCO Software. The current charges can be found within the Schedule of specified communications charges. High Grade Lines in the UK take around 60WDs to install from the point of order, the time taken to install HG lines in Europe is dependent on the exact location and can be discussed at the point of order.

What do I need to do?

Place a Communication Line Request . Once you have decided which service you require you will need to place an order with Elexon.
For a more detailed view of setting up communication lines, please refer to the Communication Line process diagram.
