BSC explained


The Balancing and Settlement Code (BSC) is a legal document which defines the rules and governance for the balancing mechanism and imbalance settlement processes of electricity in Great Britain. The Balancing and Settlement Code Company (BSCCo) is administered by Elexon.

History of the BSC

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

More about BETTA

Modification P108 proposed to authorise BSCCo to provide or procure assistance to the Gas and Electricity Markets Authority in connection with the development and implementation of the British Electricity Trading and Transmission Arrangements (BETTA).
