What the Victorian Declared Wholesale Gas Market (DWGM) is for

The DWGM Declared Wholesale Gas Market. A Victorian gas market that allows trading on injections and withdrawals from the Declared Transmission System (DTS). enhancements aims to promote the transparent and effective trade of gas within Victoria as the state transitions to a renewable, sustainable energy system which can include distribution connected facilities.

This DWGM enhancements project replaces the currently obsolete Wholesale Market AMDQ Procedures with the removal of the AMDQ regime effective 1 January 2023. It also introduces a new entry and exit capacity certificate regime.

The new regime introduces:

• Entry capacity certificates that provide injection tie-breaking benefits – AEMO Australian Energy Market Operator is creating a new interface in the Markets Portal Web applications for registered participants only. Requires access to MarketNet. for Market Participants to participate and trade in the capacity certificates auctions, conducted bi-yearly for 3 years (36-month period) ahead of consumption time.
• Exit capacity certificates that provide withdrawal tie-breaking benefits - Reporting interface/ platform for DWGM Capacity PASA Availability, as described in clause 3.7.2(d)(1) of the National Electricity Rules and the NER glossary. Certificates Auction reports for all Market participants and related reporting bodies.
• AEMO operates the capacity certificates auction to allocate capacity certificates.

Capacity certificates are for entry or exit within a zone and AEMO determines the capacity certificates zones and publishes these in a register. AEMO also conducts system capability modelling at least annually to inform its determination of the types and amounts of capacity certificates available at each auction.
