Transgrid – Adjustment Proposal – Central West Orana Enabling Project – 2026–27 Adjustment – March 2026

On 31 March, we received an annual revenue adjustment proposal from Transgrid relating to the Enabling Central-West Orana Renewable Energy Zone Network Infrastructure Project (CWO Enabling Project). 

Transgrid’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 will assess Transgrid’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).

Following our assessment, we will determine an updated maximum allowed revenue, quarterly schedule of payments and revenue models for this project. Consistent with our non-contestable Guideline, we will endeavour to complete this process within 42 business days.
