About 20,000 households were without power last night after "unique" weather conditions caused faults in the Western Power network across Perth.
There were more than 150 pole-top fires in the metropolitan area.
A Western Power spokeswoman said the faults had been caused by a sudden drop in temperature and light rain after a long hot period.
The worst affected areas were Hamilton Hill, Balcatta, Bassendean, Atwell, Coolbellup and Eden Hill.Sponsored links
