The AER is responsible for monitoring activity in the Short Term Trading Market, Victorian Gas Market and Gas Supply Hub markets and on the National Gas Market Bulletin Board. The AER’s weekly gas market analysis forms an important part of this work. They contain information on market outcomes, price movements, demand changes, flows, and production. By monitoring activity in these markets, the AER is able to keep up to date with market conditions and identify compliance issues.
Due to a change in the default pipeline flow direction applied to the NSW-Vic interconnect Bulletin Board data from 27 June 2017, estimated domestic gas flows in the Bulletin Board map from this date have been inaccurately calculated (published values have been shown with an average error magnitude of around 13 TJ). Recent weekly reports have been adjusted for larger errors, affecting the periods 24 - 30 September and 17 – 23 September.
