On 14 October 2014, the Authority modified the GD1 PCFM by:
- moving the allowance allocated to Repex tier 2 mains (RE) from the row for non- variant allowed repex in the PCFM to the relevant row for the RE allowance.
On 8 September 2015, the Authority modified the GD1 PCFM by:
- amending a formula on the Input worksheet, to ensure that appropriate time value of money factors are applied to the spreading of legacy adjustment values across the RIIO-GD1 price control period; and
- amending the Tax Trigger worksheet to allow different Tax Trigger Type B event values to be entered for each licensee.
