Final decision

On 30 April 2015, we released our final decision on Ausgrid's distribution determination for the 2014-19 regulatory control period.

We also released a Fact Sheet to accompany and summarise our final decision. The purpose of this Fact Sheet is to make our decision accessible to a wide ranging consumer audience.
