Stakeholder relations manager Paul Roberts said forecast wind gusts exceeding 90kmh across South Australia and up to 120kmh in the Adelaide Hills could cause extensive damage to the overhead electricity network.
“The combination of high winds and thunderstorm activity and the extended and widespread nature of the forecast storm activity will be a challenge,” Mr Roberts said.
“A further issue is that the ground is saturated from recent rain, making it likely that in some areas we will have real issues accessing infrastructure to make repairs and restore power.”
Mr Roberts urged consumers to prepare for extended outages.
“First and foremost people need to stay safe by keeping themselves and others clear of any downed electricity wires and reporting them immediately to us on 13 13 66,” Mr Roberts said.
“We recommend ensuring items like smartphones and laptops are kept fully charged and that customers have a battery-powered radio on hand so they can keep in contact with storm and related information.”
