CP1364 – Remove BSC Systems constraint on maximum negative CALF values

Formal title: Remove BSC Systems constraint on maximum negative CALF values

Current Status

CPC Consultation
Committee Decision
Awaiting Implementation


BSC Systems currently limit the Credit Assessment Load Factor (CALF) data item to one digit before the decimal point. This forces some Suppliers with SVA embedded generation and negative CALF values to put up more Credit Cover than is actually needed to cover their estimated indebtedness. CP1364 will amend BSC Systems to allow CALF values with up to four digits before the decimal point to be used in the Credit Cover calculation. However, these bigger values will be capped for reporting purposes to avoid National Grid and Parties having to change their own systems.


CP1364 was raised and issued for industry impact assessment as part of CPC00706 on 25 November 2011, with responses due by 22 December 2011. CP1364 was approved by ISG at its meeting on 24 January 2012 for inclusion in the June 2012 Release.
