What ELEXON does

ELEXON is vital to the smooth operation of the wholesale electricity market. We compare how much electricity generators and suppliers said they would produce or consume with actual volumes. We work out a price for the difference and transfer funds accordingly. This involves taking 1.25 million meter readings every day and handling £1.5 billion of our customers’ funds each year.

The rules are set out in the Balancing and Settlement Code (BSC). We administer the Code and provide and procure the services needed to implement it. Our expertise and impartiality give our customers the confidence that the BSC operates efficiently and accurately.

  • Our customers

    It is a condition of holding a Generation or Supply License to sign up to the BSC. Therefore our customers, known as BSC Parties, cover the entire wholesale electricity sector in Great Britain and include suppliers, generators, distributors, traders, and energy importers and exporters.

    Read more about BSC Signatories and a list of all Parties.

  • Our expertise

    We deliver the BSC in an effective, efficient and economic way by focusing on four main areas:

    Procuring and managing contracts

    Rather than employing people directly to process BSC data and manage and develop the necessary software and systems, our expertise lies in procuring partners to deliver outstanding value services to our customers.

    Find out more about our procurement and contract management.

    Delivering high-quality services

    Working with our partners and suppliers, we ensure that the complex IT systems and business processes we are responsible for delivering meet the high levels of service management that our customers rightly demand.

    Managing change

    Change is a constant in the electricity sector and the BSC needs to evolve and adapt to changing circumstances. We manage the process of changing the BSC in close consultation with our stakeholders so that the BSC remains as relevant and effective as possible.

    Find out more about our change process.

    Assuring that the BSC arrangements work

    We run a framework of performance assurance standards to ensure that everyone who works with us, and operates within the Balancing and Settlement arrangements, meets the standards and obligations of the BSC, and our customers have confidence that the BSC operates efficiently, accurately and fairly.
