On 31 March 2017, ActewAGL submitted to the AER an annual pricing proposal for the Australian Capital Territory electricity distribution network for the period 1 July 2017 to 30 June 2018.
On 9 May 2017, ActewAGL submitted to the AER a revised 2017-18 pricing proposal to correct for errors in its unders and overs accounts.
On 17 May 2017, the AER published the approved ActewAGL revised 2017-18 pricing proposal and the enforceable undertaking the AER accepted from ActewAGL. This was after the AER assessed ActewAGL's revised pricing proposal as compliant with its enforceable undertaking and its approved 2017-19 Tariff Structure Statement.
The AER and ActewAGL have developed a new enforceable undertaking which sets out how its revenues and network tariffs will be determined from 1 July 2017 to 30 June 2018. The enforceable undertaking also obliges ActewAGL to continue to provide network services consistent with the non-price terms and conditions of its 2015-19 electricity distribution determination. A similar approach was undertaken for the period 1 July 2016 to 30 June 2017. The main change is that the new enforceable undertaking will facilitate the application of ActewAGL's Tariff Structure Statement which takes effect on 1 July 2017.
ActewAGL offers the enforceable undertaking because in February 2016 the Australian Competition Tribunal set aside the AER’s May 2015 distribution determination decision for ActewAGL. Subsequently, the AER sought judicial review of the Australian Competition Tribunal decision in the Full Federal Court of Australia and the outcome of this review is yet to be handed down. An enforceable undertaking can set out placeholder arrangements that provide transparency and certainty over network tariffs, on an interim basis, until the allowed revenue that ActewAGL may ultimately recover from customers is determined through the appeals process.
The AER's approach to establishing new interim arrangements through entering into new enforceable undertakings with the ACT and NSW electricity distributors was set out in an open letter published on the AER's website in April 2017.
