Assessment of Network Outage Event on 22 November 2025 - Power and Water Corporation

The Commission has published an assessment under clause 5.4.4 of the Electricity Industry Performance Code for the purpose of verifying that a network outage event in the Darwin region on 22 November 2025 was outside of Power and Water Corporation’s control, and therefore able to be excluded from its network performance reporting and guaranteed service level payments.

On 22 November 2025 Severe Tropical Cyclone Fina (STC Fina) impacted Darwin region, causing damage to the distribution infrastructure which resulted in prolonged network outages for a significant number of electricity customers. Power and Water Corporation notified the Commission and submitted a report in accordance with the requirements of the Electricity Industry Performance Code. The report proposed to exclude the events commencing on 22 November 2025 from adjusted category performance reporting and guaranteed service level payments.

The Commission has verified the network outage event was due to a natural event and is a statistical outlier and was therefore outside the control of Power and Water Corporation. As such, the Commission considers the event an excluded event for the purpose of the Electricity Industry Performance Code.
