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 ‘ET2 PCFM for AIP 202X’ for each respective year.
Part C of special condition 8.1 provides for Ofgem to make modifications to the ET2 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.
The version of the PCFM published following an AIP is titled ‘ET2 PCFM November 202X’ until regulatory year 2022. Starting from regulatory year 2023, the version of the PCFM published following an AIP is titled ‘ET2 PCFM AIP 202X’.
