Short Term Trading Market
The Short Term Trading Market (STTM) is a market-based wholesale gas balancing mechanism established at defined gas hubs. The market uses bids, offers and forecasts to determine schedules for deliveries from the pipelines transmission users and the hubs. The market sets daily market prices and settles each hub based on the schedules and deviations from schedules.
AEMO operates the STTM but does not operate the physical pipeline or network assets.
