P040 – Calculation of Negative Estimates of Annual Consumption (EAC)

Formal title: Calculation of Negative Estimates of Annual Consumption (EAC)

Summary

Amendments to calculation of EACKR in BSC Annex S-2 paragraph 4.3.7. This will introduce an extension to this calculation to remove the ability for EACKR to be calculated as a negative value. Negative EACs are logically inconsistent and should be replaced by a more appropriate value. This would minimise inaccuracies in settlements and ensure a Public Distribution System Operator (PDSO) does not have any material unbilled Use of System or cashflow impact.
