Our approval role

A cost pass through event is one that occurs beyond the reasonable control of a network business and has not been accounted for in its current 5-year revenue determination.

Examples can include new statutory obligations imposed on the business or extensive damage to infrastructure caused by a natural disaster.

They can occur at any time during a regulatory control period.

Under the National Electricity Rules, network business can submit a cost pass through application to the AER to recover its efficient costs incurred by the event.

We undertake a rigorous assessment of the application and make a cost-recovery determination based on the principle that consumers should pay no more than necessary for safe and reliable energy. Apply Wizard filter
