Becoming a Supplier

Glossary

This page lists and details the step-by-step process of becoming a Supplier. 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 a Supplier?

Suppliers are licensed by Ofgem to supply electricity to domestic and non-domestic premises. Suppliers buy electricity to meet their customers’ demands from Generators or from other Parties trading in the market.

Suppliers are responsible for the Meters that record the amount of energy that their customers are consuming and are also responsible for the performance of their Supplier Agents which include Data collectors, Data Aggregators and Meter Operators.

Qualifications needed

In order to qualify as a Supplier you will need to obtain the following qualifications:

The Central Volume Allocation (CVA) Qualification is needed to prove that Suppliers have the ability to send certain communications to BSC Agents and ensure that certain communications are received 

The Supplier Volume Allocation (SVA) Qualification is needed to ensure that Suppliers understand the obligations and activities of the BSC and maintain a certain performance level.

Costs

Suppliers 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. 

Credit cover

Charges are made to Parties (or by them) as a result of any imbalance (Trading Charges) 29 days after a Settlement Day. Over this period a Parties’ Credit Cover ensures it has enough collateral to cover these payments in case of default.

We do not specify the amount of Credit Cover you must lodge; it is up to the Party to decide. Parties usually make this decision based on their trading characteristics.

For more information on Credit Cover please refer to the Overview of Credit Cover or email [email protected]

A charge is made against every CVA BM Unit for which the Supplier is the Lead Party for all or part of the month. If the BM Unit is a Production BM Unit at an Export Exempt site where there are also one or more Consumption BM Units, then no charge is made.

If there are Production BM Units at an Export Exempt site, where there are no Consumption BM Units, then one charge is made for all BM Units at that site.

A charge is also payable against a Party’s Gross Contract Volume.

If a Supplier has any additional BM Units to those described above for which it is the Lead Party, then it must also pay a charge for those.

Participant Test Service charges

For new Suppliers entering the market an initial 1/2 day Participant Test Service (PTS). 

The PTS is a test system, similar in configuration, to the live BSC central systems environment. It is available to BSC Parties, Party Agents, third party software providers & Elexon to increase the level of assurance to individual companies, and to the industry as a whole.

You can use the PTS service before competing CVA Qualification testing and operating in the live environment, and to test any impacts as a result of changes to your business software.

To book a PTS test slot please submit a completed PTS Booking Form to the BSC Service Desk.

Participant Test Service Test Slot (£/half day) = £947 + VAT
