The AER made the revenue determination for ACEREZ as the Network Operator for the main Central-West Orana REZ network project under the Electricity Infrastructure Investment Act 2020 (NSW) in December 2024. This revenue determination included adjustment events/mechanisms that allow for changes to the schedule of payments to be paid to ACEREZ over the project term.

On 2 July 2026, the AER received a revenue adjustment proposal from ACEREZ. 

ACEREZ has proposed to apply three adjustment mechanisms in the revenue determination. The proposed adjustments would update the schedule of payments to reflect:

• additional costs for administering the NSW Strategic Benefit Payment Scheme;
• differences between forecast and actual consumer price index outcomes; and 
• differences between forecast and actual wage price index outcomes.

Consistent with our Revenue determination guideline for NSW contestable network projects, we will endeavour to make our revenue adjustment decision within 42 business days of receipt of the revenue adjustment proposal.
