Allocation of Unidentified Gas Expert (AUGE)
Not all gas used in Britain is measured and accounted for in settlements. The Allocation of Unidentified Gas Expert (AUGE) analyses potential sources of Unidentified Gas (UIG) and proposes a methodology for accounting for it, and for sharing the cost fairly between market participants.
These so-called Weighting Factors are approved each April by the Uniform Network Code (UNC) Committee for use in the following gas year. The Weighting Factors are the result of extensive analysis and are set out, along with a description of our methodology, in the AUG Statement.
A fair allocation of UIG supports effective competition, as it influences the wholesale charges between Shippers and Suppliers and hence the prices that Suppliers offer customers.
To ensure transparency, we maintain a dialogue with industry stakeholders, and provide monthly progress updates on our process and methodology. These updates are published on the website of the Joint Office of Gas Transporters, along with the progressive iterations of the AUG Statement throughout the year, culminating in the Final AUG Statement and Table, which is published by the end of March.
