AER - Amended gas distribution PTRM - half year extension - December 2021

The AER has published a position paper, amended Post Tax Revenue Model, and amended depreciation tracking module setting out its proposed approach to the determination of revenue and prices for the 1 January to 30 June 2023 extension period. We have also published the amended Roll Forward Model (incorporating the extension period), which is to be used for the determination of revenue and prices for the subsequent period commencing 1 July 2023.

These will inform both the requirements of the April 2022 proposals and the basis for our decisions.
