Generator notice of closure exemption guideline

Exemption guideline
Date initiated: 
1 March 2019
Effective date: 
1 September 2019
AER reference: 


From 1 September 2019, generators will be required to provide at least 42 months' advance notice of their intention to close, unless we grant an exemption. We are required to publish guidelines for how we intend to handle applications for exemption, and what information applicants will be required to submit. The AER is currently developing this guideline.

We published a draft exemption guideline and draft decision on 7 June 2019 that sought stakeholder comment on our proposed approach for the generator notice of closure exemption process. We are currently considering the submissions we received. Prior to developing the draft guideline, we also published an issues paper that sought comment on key issues related to the guideline’s development. The consultation period for this issues paper closed on 5 April 2019.

Minimum notice period

As of 1 July 2019, the minimum notice period has increased from three years to 42 months.
