On 5 November 2018 the AEMC received a rule change request from the Victorian Minister for Energy, Environment, and Climate Change to amend the National Gas Rules and consider the introduction of a forward trading market to operate in the Victorian declared wholesale gas market (DWGM). 

The proposed voluntary market would:

  • facilitate the trading of forward contracts for physical gas
  • be based broadly on the design of the gas supply hubs currently operating in Wallumbilla and Moomba
  • operate on the Trayport platform
  • offer a range of contract tenures (e.g. daily, weekly, monthly, seasonal)
  • settle any variances between traded and scheduled quantities at the 6AM DWGM price on the gas delivery day specified in the forward product.

Draft determination

On 4 July 2019 the AEMC released a draft determination not to make a rule.

There are currently several options for participants in the DWGM to manage their spot price risk, including trading gas at trade-points just outside the declared transmission system, trading financial products on the ASX, and trading bilaterally negotiated contracts such as gas supply agreements (GSAs) and over-the-counter (OTC) contracts.

Analysis conducted as part of the AEMC’s 2017 Review into the Victorian Declared Wholesale Gas Market found minimal trading of risk management products, and proposed investigating the introduction of a forward trading market to improve spot price risk management options.

However, since that time there has been an increase in trades on the ASX Victorian gas products, and the ASX is intending to introduce a market maker for these products, as it has done with its electricity products. Several brokers have entered the Victorian gas market in the past year which is expected to facilitate more trading on the OTC market. Information transparency about gas contracts has also improved due to increased trades on publically listed ASX products, data in the ACCC gas inquiry interim reports and, at a cost, through brokers.

In light of these developments, and after consulting with market participants, there is no longer a clear need for an additional spot-price risk management market.

There are costs associated with setting up a forward trading market. For example, AEMO would need to update its IT systems and settlement processes, and market participants would need to update their internal strategies, systems and processes. The level of participation in the new market would need to be sufficient to outweigh these implementation costs and  it is not clear this will occur.

The Commission invites stakeholders to provide written submission on the draft determination by Thursday 22 August 2019.

Workshop

The AEMC held a public workshop in Melbourne on 16 May 2019. Slides from the workshop are available below.

Background

On 5 November 2018, the AEMC received three rule change requests from the Victorian Minister for Energy Environment and Climate Change to amend the National Gas Rules (NGR). The rule change requests proposed the following changes:

  • introduce a clean and simple wholesale gas price for the DWGM in Victoria (DWGM Simpler wholesale price)
  • establish a forward trading exchange which will make it easier for buyers and sellers to trade gas and lock in a future price in the Victorian gas market (DWGM Forward trading market)
  • improve the allocation and trading of pipeline capacity rights (DWGM Improvement to AMDQ regime).

These requests were based on recommendations made by the AEMC in June 2017, as part of the Review of the Victorian declared wholesale gas market final report (DWGM Review).

The Commission is continuing to assess these other two rule changes, with draft determinations expected in September 2019.
