AER – Final decision – Ausgrid – Hunter Central Coast RNIP 2026–31 – Adjustment 2026–27 – PTRM – May 2026

On 27 March, we received an annual revenue adjustment proposal from Ausgrid relating to the Hunter-Central Coast REZ Network Infrastructure Project (HCC Project). 

Ausgrid’s proposal included routine adjustments to replace placeholder financial inputs determined in our final decision with actual financial inputs. It also included non-routine expenditure adjustments. We assessed Ausgrid’s proposal against the requirements in the revenue determination, EII Regulation and the Revenue determination guideline for non-contestable network infrastructure projects (Non-contestable Guideline). We have completed our assessment within 42 business days, consistent with our Non-contestable Guideline.

On 26 May 2026, in line with the adjustment mechanisms specified in the final decision, we have determined an updated quarterly schedule of payments for the HCC Project. We have published this updated quarterly schedule, alongside the revenue model and a statement of reasons which sets out our assessment of each adjustment contained in Ausgrid’s proposal.
