Western Power’s inbuilt safety mechanisms were triggered this afternoon to protect customers after a major power station tripped off.
The rare event caused a significant fluctuation in network’s stable frequency.
To protect customer electricity supply and appliances and limit outages the network’s safety precautions worked as they were designed and began to shed power load.
Once teams at the Network Operations Control Centre were able to stabilise the system we were able to safely and quickly restore customers to network power.
At one stage over 130,000 customers were affected by the generation triggered outage at around 4.30pm.
All customers impacted by the outage were restored by 5.20pm.
- If you see fallen powerlines, stay clear and make the safe call to Western Power's emergency line on 13 13 51
- If powerlines fall across your car, stay inside the car until help arrives
