Balancing Settlement Code (BSC)

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

The code covers the metering of the physical production and demand for electricity from generators, suppliers and interconnectors in relation to their contracted positions. And it also covers the calculating and settling of any imbalances when delivery or offtake doesn’t match those positions.

The BSC sets out a framework for making a submission to buy or sell electricity into or out of the market at close to real time.

It’s administered by ELEXON but there’s some related information here that you might find useful.

For more information, contact [email protected].

BM reporting platform

BM reporting platform

The Balancing Mechanism Reporting Service (BMRS) is the main source of operational data for electricity balancing and settlement arrangements. It’s used by traders, regulators, industry forecasting teams and academics to make trading decisions, and understand market dynamics (among other things).

Go to the BMRS website

MODIS

MODIS

The Market Operation Data Interface System (MODIS) reports on market data, with a focus on data for the European Transparency (ETR) and REMIT regulations. We developed MODIS as a separate system to make sure balancing of the system wasn’t compromised.
