Re: Application by ElectraNet Pty Limited (No 3)

In the case of ElectraNet Pty Limited (No 3), the applicant sought review of a decision made by the Australian Energy Regulator (AER) regarding the regulatory asset base (RAB) of ElectraNet. The dispute centred on the adequacy of the evidence used by the AER to assess the RAB, specifically concerning the valuation of easements owned by ElectraNet. The Australian Competition and Consumer Commission (ACCC) and the Electricity Consumers' Council of South Australia (ECCSA) intervened in the proceedings, with ECCSA challenging the sufficiency of the evidence and the ACCC arguing that the RAB was closed and should not be adjusted. The matter was ultimately heard by the Australian Energy Regulator Tribunal (AER Tribunal).

The key legal issues before the AER Tribunal were whether the AER had erred in its assessment of the RAB for ElectraNet by not adjusting the RAB to account for transaction costs associated with the easements, and if so, whether the AER's decision should be varied. Additionally, the tribunal had to consider the sufficiency of the evidence presented to the AER regarding the valuation of the easements and whether the AER's decision was in accordance with the applicable rules and regulations.

The AER Tribunal found that the AER had indeed erred in its assessment of the RAB by not adjusting it to account for the transaction costs of the easements. The tribunal noted that the AER had before it sufficient evidence to make this adjustment, and that the rule in question provided ElectraNet with the opportunity to have its RAB adjusted if it met certain criteria. The tribunal concluded that ElectraNet had satisfied these criteria and that the AER's failure to adjust the RAB accordingly was an error. Furthermore, the tribunal rejected ECCSA's contention that the RAB was closed and that the easement valuations were irrelevant, finding that these arguments were not supported by the evidence or the relevant rules.

In light of these findings, the AER Tribunal determined that it was required to make a determination itself under section 71P of the Law. The tribunal proposed to vary the reviewable regulatory decision of the AER by adjusting the opening RAB of ElectraNet to include the transaction costs for the easements, indexed by the Consumer Price Index from 1 July 2000 to 1 July 2008, in addition to the sum already added by the AER for easement compensation costs. The tribunal exercised its full powers and functions under the Law and the Rules in reaching this decision.
