The State Government has doubled the compensation payout for people affected by the power outages over Christmas.
The blackouts began on Christmas Eve and at its peak, around 34,000 households and businesses were without power on Boxing Day.
The four-day heatwave, which saw temperatures above 40 degrees, caused "individual feeder failures" and "challenges reconnecting the grid".
"Some of the most impacted areas were Baldivis, Dawesville, Clarkson, Mindarie, South Yunderup, Roleystone, Kelmscott and Bouvard; the majority of these households had their power restored by Monday evening," Energy Minister Bill Johnston said.
"We acknowledge the inconvenience and disappointment this caused over the Christmas period."
