About the Declared Wholesale Gas Market (DWGM)
A Victorian declared wholesale gas market (DWGM) was established in 1999 to enable competitive, dynamic trading based on injections into, and withdrawals from, the transmission system that links multiple producers, major users and retailers. In 2007, intra-day trading intervals were introduced.
This market is unique, as most Australian gas markets are based on bilateral arrangements between producers, major users, and retailers, linked together through pipeline hubs connecting gas fields to gas consumers.
