Market operations

Market operations refers to the functions, activities and processes that support the effective operation of the Gas Supply Hub (GSH). This section of the site therefore includes key guides, agreements and forms relating to the market, as well as information on settlements, payments and clearing.

About the market

The GSH is a voluntary market that supports a faster response, and greater liquidity and flexibility, in trading gas. It provides a centralised trading, settlement and clearing facility through an online portal, and enables generators, users, producers and retailers to manage their daily and future gas requirements.

AEMO offers spot and forward-dated products for participants to trade at the hub. The spot transactions include a core ‘day-ahead’ and an ‘on-the-day’ product. The on-the-day product enables parties to adjust their portfolio closer to real-time and to manage imbalances within the gas day. Weekly and monthly products are also available to be traded. 

Pipeline Capacity Trading (PCT) is also offered as part of GSH, allowing pipelines to be used more efficiently and helping to create more opportunities to trade gas.
