ELEXON compares how much electricity generators and suppliers say they will produce or consume with actual volumes. We work out a price for the difference and transfer funds. This involves taking 1.25 million meter readings every day.

BSC and codes

The BSC and related codes information is an essential part of understanding the formal procedures that govern the electricity industry.

Committees & Groups

The Balancing and Settlement Code is governed by the BSC Panel and its committees and industry groups. They meet to fulfil the duties of the BSC and discuss issues around day to day operations. This includes how changes to the BSC itself, Code Subsidiary Documents and BSC Systems are developed, assessed and implemented.

Managing the Change process

The BSC Change process is used to introduce changes to the BSC arrangements in response to any concerns, problems or defects that Parties may identify in the current processes. Under these processes, changes can be made to the Balancing and Settlement Code, its Code Subsidiary Documents and to BSC Systems.

Compliance procedures

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. This helps our customers have confidence that the BSC operates efficiently, accurately and fairly.

Training and guidance

ELEXON runs regular training sessions for people involved in the electricity industry. These include an overview of the BSC and specific sessions of key parts of working in the electricity industry. We also produce a collection of guidance pages to help explain the various processes and activities involved.

Technical and business services

We work with a range of partners and suppliers to ensure that the complex IT systems and business processes we are responsible for delivering meet the high levels of service management required by our customers.

The Design and Delivery department at ELEXON is responsible for delivering Modifications and Changes to the BSC. This includes the central systems required to deliver BSC agent responsibilities.

Our Foundation Programme aims to remodel and update the BSC central systems so that they can deliver a flexible, scalable and open digital platform for our settlement and balancing services.
