Elexon is a private, not-for-profit business that oversees the processes that settle payments between generators, suppliers and traders. It compares the amount of electricity that generators say they will produce and how much suppliers say will be consumed, while also working out the price difference and overseeing the transfer of funds between all parties.

Elexon operates under the rules of the Balancing and Settlement Code, often known as BSC, working within these guidelines to create the required services.

Electricity cannot be stored so must be used in real time, which means that supply must be able to meet the demand at any one time. That’s why suppliers require a trading system and a method of settlement. Elexon oversees this settlement process, ensuring that suppliers are paid for the electricity that is being used.

It does this by dividing electricity use into half hour periods, called Settlement periods, which suppliers use to purchase energy for their customers from generators.

What services do Elexon offer?

As part of its role, Elexon processes about 1.25 million meter readings every day. In doing so it settles around 37TWh of electricity and handles billions of pounds worth of funds. Its work sees it manage services for hundreds of individual organisations within the energy industry, including:

  1. Distributors
  2. Generators
  3. Traders
  4. Suppliers

Elexon acts as a critical friend to the industry by providing training and customer support, as well as its main service of administration through the BSC. They analyse change within the industry and participate in consultations to provide guidance to the organisations it supports.

It can also provide impartial support on policy delivery and outcomes, as well as keeping one eye on the market for future developments.

Who owns Elexon?

Elexon is owned by the National Grid but it is fully funded by and accountable to its customers. That is the almost 500 signatories of the BSC. That means it is a not-for-profit service provider to the industry and independent from any operations. In addition, although the National Grid owns Elexon, it does not have a seat on its board or make executive decisions.

What is the Balancing and Settlement Code?

The Balancing and Settlement Code is part of the New Electricity Trading Settlements that were introduced in England and Wales in 2001. It is essentially a requirement placed on the National Grid that forms part of its licence to transmit electricity.

Elexon is the organisation that administers the BSC on behalf of the National Grid. All of the licensees who work with the National Grid are also bound by this code, giving Elexon the power to implement it. It ensures that services are delivered in an efficient manner and all agents are working within the boundaries of the code.
