Formal title: Roll over of BSC Seasonal GCDC
The Modification proposes to amend BSC Section K to allow Elexon to carry over BSC Seasonal GC/DC.
This Modification seeks to remove the requirement to default values to zero if none is declared, and recognise the existing working practice where Elexon carries over BSC seasonal GC/DCs where no declaration is received. This Modification is explicitly intended so there is no challenge process to a rolled-over value. Instead, if Parties want to they can re-submit their DC if dissatisfied with the rollover value in accordance with existing mid-Season re-declaration processes (Section K3.4.2A).
