More than 4000 homes across Perth’s northern suburbs lost electricity on Thursday night, only a day after Western Power was slammed by the State Government for mass Christmas blackouts.
Residents in the Clarkson and Kinross area have been told they will have to wait until at least 9pm on Thursday for their electricity to be restored.
An unknown cause cut power to 4088 homes.
Energy Minister Bill Johnston on Wednesday ordered Western Power to improve its planning, forecasting, transparency and operational response to extreme events following an inquiry into the Christmas blackouts that affected 107,000 households in a report handed to WA’s Parliament.
Many families affected were unable to use their air conditioners and had to bin large quantities of spoiled food leftover from Christmas as temperatures topped 40C for several consecutive days.
The findings of the inquiry into Western Power were released several weeks after chief executive Ed Kalajzic resigned.
The outages were largely caused by “overloads on the distribution network” and the combination of weather conditions and high levels of customer demand exceeding the capacity of some networks.
The extended outages were blamed on higher fire risk conditions and Western Power not having enough time to fix the underlying cause before demand peaked again in the same section of the network the following day.
But Mr Johnston said the blackouts were not due to a lack of maintenance.
“The report shows that while Western Powers planning processes were to industry standard, they can still be improved,” he said.
