Aurora’s application is significant and is approximately double the allowances we set Aurora for the previous comparable periods.

Aurora says its investment plan is required to address historic under-investment in its network which has resulted in a gradual deterioration of its equipment including lines, poles and transformers. In recent years this has resulted in a higher number of safety incidents and an increasing number of unplanned power cuts.

To pay for this, Aurora had forecast significant increases to power bills. You can read Aurora’s final proposal here.

We understand that now, more than ever, household incomes will be strained, especially in light of COVID-19. Many consumers will be struggling to pay their bills while needing a reliable electricity supply.

Our role in Aurora’s investment plan is to set network reliability standards and determine how much money it should be allowed to recover from its customers to carry out its plan and over what period.

On 31 March 2021 we published our decision on Aurora’s CPP. Overall, we consider Aurora has made its case for a step up in investment in its network. Without a CPP, its network would continue to deteriorate, safety incidents would increase, and its customers would experience more, longer, outages.

We have decided to allow Aurora to recover $46 million less from its customers than it had asked for on a five-year CPP. This reduction is because we consider some of its expenditure could be deferred to a later date and some was not sufficiently justified to the level Aurora had sought. Even so, Aurora would be able to significantly increase its expenditure to address the issues on its network and recover the cost from its customers.

To help mitigate the impact of increased bills we have capped Aurora’s annual revenue increases at a level approximately 10% per year.

We have also amended Aurora’s quality standards for unplanned outages to better reflect the state of its network. This has not been set at the levels Aurora requested but would allow it to meet targets that reflect its performance over the past five years. Overall, this should see the reliability of supply stabilise at current levels before gradually improving over time.

Alongside our decision on Aurora’s CPP, we have released our draft decision on additional reporting measures that are designed to improve the ability of customers to hold Aurora to account. These would require Aurora to publish a yearly report on its progress on delivering the investment plan, present this report to customers directly, and report more clearly on service quality and regional pricing issues.

A summary of our final decision on Aurora’s CPP and our draft decision on additional reporting measures, consumer fact sheet and the full reason paper are all available below by clicking on the 'Documents’ tab.

Submissions on our draft decision on Aurora Energy's information disclosure requirements closed on 10 May. We will consider these submissions before publishing our final decision on these additional reporting measures. We expect to make our final decision in August 2021.
