Ofgem is required to update and publish the model annually as part of the Annual Iteration Process (AIP), under Part D of the electricity transmission special condition 8.1. We name these ‘GD2 PCFM for AIP 202X’ for each respective year.
Part C of special condition 8.1 provides for Ofgem to make modifications to the GD2 PCFM. These modifications are published during each regulatory year and are shown in the subsidiary documents list with the suffixes ‘C01,’ ‘C02,’ and so on.
