Balancing framework and the Balancing and Settlement Code (BSC)

Here you will find documents required by and relating to our licence, and information about the electricity balancing system (EBS) project.

Balancing and Settlement Code (BSC)

The Balancing and Settlement Code (BSC) contains the rules and governance arrangements for electricity balancing and settlement in Great Britain.

The code covers aspects relating to metering of the physical production and demand for electricity from generators, suppliers and interconnectors against their contracted positions; and calculating and settling the resulting imbalances when the delivery or offtake does not match contractual positions.

The BSC details the framework for parties to make submissions to us, to either buy or sell electricity into/out of the market at close to real time.

The BSC is administered by ELEXON.
