Background

In accordance with clause 6.20.6 of the Wholesale Electricity Market (WEM) Rules, AEMO commissioned a review of the Energy Price Limits for the Wholesale Electricity Market (WEM) in the South West Interconnected System. 

AEMO engaged Marsden Jacob Associates Pty Ltd (Marsden Jacob), an independent consultant, to assist AEMO in preparing the draft report for the annual review of the Energy Price Limits for 2019-20.

On 12 April 2019, AEMO published an invitation to provide submissions and a draft report prepared by Marsden Jacob. In accordance with clause 6.20.6 of the WEM Rules, AEMO invited all sectors of the Western Australian energy industry, including end-users, to make submissions on the draft report by 24 May 2019. 

During the consultation period, AEMO received feedback from stakeholders including comments on the methodology used to calculate the variable operating and maintenance costs. After reviewing the feedback in collaboration with AEMO, Marsden Jacob recalculated the Energy Price Limits.

On 21 May 2019, AEMO published a revised draft report. In accordance with 6.20.9A of the WEM Rules, AEMO published a request for further submissions. The call for further submissions extended the deadline for submissions to 31 May 2019. 

On 12 June 2019, AEMO provided the Economic Regulation Authority (ERA) with its proposed values for the Energy Price Limits for 2019-20. 

Approval of 2019 Energy Price Limits 

On 26 July 2019, the Economic Regulation Authority (ERA) approved AEMO’s proposed revised values for the Energy Price Limits for the 2019-20 financial year. The ERA’s determination is available on its website.

AEMO did not receive any formal submissions during the consultation period.
