Elexon’s role managing the BSC
The Balancing and Settlement Code (BSC) was introduced as part of the New Electricity Trading Arrangements (NETA), which came into force in England and Wales in March 2001. These arrangements, and the scope of the BSC, were subsequently extended to Scotland in April 2005 as the British Electricity Trading and Transmission Arrangements (BETTA).
The BSC contains the rules and governance arrangements for the Balancing Mechanism and imbalance settlement processes. Elexon oversees the strategic operation and day-to-day management of the Balancing and Settlement Code (BSC). 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. Our expertise and impartiality give our customers the confidence that the BSC operates efficiently and accurately.
History of the BSC
The New Electricity Trading Arrangements (NETA) and the British Electricity Trading and Transmission Arrangements (BETTA) were established to reform the electricity market in the UK.
NETA: Introduced on March 27, 2001, NETA aimed to create a more competitive and efficient electricity market in England and Wales. It allowed electricity to be traded closer to real-time, promoting competition among generators and suppliers.
BETTA: Launched in April 2005, BETTA extended the principles of NETA to include Scotland, creating a single electricity market for Great Britain. It aimed to enhance competition and efficiency across the entire UK electricity market.
NETA and BETTA were established to:
- Enable electricity to be traded bilaterally, and ahead of time, between willing buyers and sellers in an open and competitive wholesale market (outside the BSC)
- Ensure that total electricity generation and demand are balanced in real time, through a Balancing Mechanism operated by National Grid as the GB Transmission System Operator
- Establish any differences (‘imbalances’) between the amounts of electricity which are traded and the actual electricity which is generated/consumed, and ensure that these are paid for, through a post-event imbalance settlement process operated by Elexon
