On 13 January 2015, TransGrid submitted our Revised Revenue Proposal 2014/15 - 2017/18 to the Australian Energy Regulator (AER).
As part of determining TransGrid's revenue and expenditure for the next five years, we were given 30 business days to review the AER's Draft Determination on our Revenue Proposal for 2014/15 – 2018/19 and submit a Revised Revenue Proposal to address matters raised by the AER.
Over the past month, we have spoken with a range of large energy users and consumer representatives on our view of the AER's Draft Determination and the impacts on our Revenue Proposal. To ensure we captured as much feedback as possible we held a workshop and hosted our first webinar for key stakeholders. A report on the opinions and feedback received on our Revised Proposal is now available here.
TransGrid proposed a move to peak demand pricing in its Pricing Methodology, in response to strong support from consumers. The AER did not approve the Pricing Methodology in the draft decision. As a direct result of feedback and suggestions in December, we remodelled the way to calculate our peak demand pricing and submitted it to the AER. The strong consumer support, invaluable input and alternate suggestions for this new approach to pricing made this possible.
As well as engaging energy users, we reviewed our proposal to ensure we could maintain a safe and reliable supply of electricity while minimising energy price impacts. The AER introduced some alternative ways of modelling expenditure in the draft decision, which we have reviewed and tested in the Revised Proposal.
Some of the key takeaways from the Revised Proposal are as follows:
The AER took submissions on our proposal until 6 February 2015. More information on this consultation is available on the AER's website.
The AER's final decision was made in April 2015. The final decision can be accessed here.
