Notice of Consultation


The Wholesale Electricity Market (WEM) Rules (Market Rules) require the Economic Regulation Authority (ERA) to determine values for Margin Peak and Margin Off Peak (Margin Values) for each financial year in accordance with the methodology set out in clause 3.13.3A(a) of the Market Rules.

Under clause 3.13.3A(a) of the Market Rules, AEMO must submit a proposal for these values to the ERA by 30 November each year for the following financial year.

AEMO has engaged Jacobs Group Pty Ltd (Jacobs), an independent consultant, to provide an independent assessment of the Margin Values for the 2018/19 financial year. Jacobs has prepared a draft Assumptions Report outlining the methodology and input assumptions proposed for the 2017 Review. The public version of this report, which excludes confidential Market Generator details, is now available.

AEMO also proposes to consult directly with selected Market Generators over the next two weeks, to refine the confidential input assumptions required for Scheduled Generators operating in the 2018/19 financial year.
