Stormy weather placed huge demands on SECWA's repair crews over the weekend.
Fuel and Energy Minister Geoff Gallop said today that the SECWA staff who had handled power supply emergencies deserved to be congratulated.
"Widespread blackouts were caused by lightning, strong winds and tree debris," Dr Gallop said.
"Most of the problems were concentrated in the Perth metropolitan area and surrounding country districts.
"Emergency telephone systems were flooded with about 3,000 calls and SECWA crews worked long hours in extremely bad weather to restore supplies to normal."
Dr Gallop said there were some instances where power was lost for substantial periods of time. Perth areas that had been significantly affected extended from Muchea to Mandurah and from the coast into the Darling Ranges.
"SECWA field crews delivered a top effort in difficult and dangerous conditions," the Minister said.
"In the period after the storm's peak on Saturday night they handled about 700 jobs."
