AER capex assessment outline for electricity distribution determinations

The capex assessment outline for electricity distribution determinations explains the obligations of the AER and distributors under the NEL and NER, and the techniques we use to assess a distributor’s capex proposal against the capex criteria and objectives. This document forms part of the supporting information for our regulatory decisions on electricity distributors’ capital expenditure from 31 January 2020.

We have previously included this information in our capital expenditure draft and final decision attachments. This document does not indicate a change to our assessment approach.
