Other Documents: Category 3


This page lists all the Category 3 BSC Configurable Items under the BSC. These documents generally hold helpful additional information to support market participant and industry processes, which are outlined in other BSC Configurable Items such as Balancing and Settlement Code Procedures (BSCPs) and the Balancing and Settlement Code (BSC) itself. Category 3 BSC Configurable Items do not follow the defined BSC Change Process, rather they have their own bespoke embedded amendment process within.

This page lists links to the PDF versions of the Category 3 documents. However, if you would prefer to access web page versions of this content, you can find these on the Digital Code site.
