On 16 August 2019, we commenced a review of the Ring-fencing Guideline (Electricity distribution) (Version 2). The objectives of this review were to include ring-fencing interactions with stand-alone power systems (SAPS) and energy storage devices and to clarify some obligations and to make compliance less administratively complex. 

On 3 November 2021 the AER published the final Ring-fencing Guideline (guideline) and Explanatory Statement (Version 3). DNSPs must comply with this version of the guideline from 3 February 2022, 3 months after publication.

On 21 December 2021, the AER published a communications statement confirming our position on streamlined waivers and an accompanying waiver application template for DNSPs to use.
