AER releases Draft Interim Market Liquidity Obligation Guideline for the Retailer Reliability Obligation for consultation

Today the Australian Energy Regulator (AER) released its Draft Interim Market Liquidity Obligation (MLO) Guideline for consultation.The guideline is one of six guidelines that the AER will develop to set out how it will exercise its functions under the Retailer Reliability Obligation.

The National Electricity Rules will create the MLO, which will require obligated parties to post bids and offers for standardised electricity products on an approved exchange during certain trading windows.

The Draft Interim MLO Guideline sets out the AER’s approach to assessing requests for approval of additional trading exchanges and standardised products, as well as its approach towards monitoring compliance with the obligation.

The AER will publish the final Interim MLO Guideline on 31 August 2019.

A final version of the MLO Guideline will be subsequently developed, using a full consultation process, and will be published by 31 December 2020.
