Decision for the determination of a proposed relevant adjustment associated with specified streetworks costs under the RIIO-GD1 price control review
Decision
The RIIO-GD1 price control for 2013-2021 allows the gas distribution network companies (GDNs) to apply to the Authority, by means of a reopener mechanism, to adjust their allowed expenditure to accommodate additional costs associated with specified streetworks costs.
The GDNs may propose relevant adjustments during two defined application windows, May 2015 and May 2018, where the amount exceeds or is likely to exceed one per cent of the relevant GDNs materiality threshold.
