What caused the power outage Perth on 3 February?

Western Power is investigating; no confirmed root cause yet. The heat above 40C likely pushed local assets near limits, raising fault risk. Most customers were restored by early afternoon. Expect an incident summary with asset and switching details in coming days.

How long did the Perth blackout last and where?

Outages hit several northern suburbs, including Scarborough, Trigg, Doubleview, Woodlands and Karrinyup, during the morning. Restoration progressed across the day, with most supply back by early afternoon. Some pockets faced longer field checks while crews made assets safe and verified load conditions.

What does this mean for investors in Australian utilities?

Treat the event as a reliability signal. Review outage frequency, SAIDI and SAIFI trends, and summer readiness plans. Look for capex on feeder automation, thermal ratings, and community batteries. If power outage perth events rise, regulators may back larger programs and reward faster restoration.

How can households prepare for future heatwave outages?

Keep devices charged, fit surge protection, and consider a home battery paired with rooftop solar. Use fans first, set aircon to 24-25C, and pre-cool earlier in the day. Register for Western Power alerts and keep a simple outage kit ready.
