On 28 September 2016, extreme weather caused a state-wide power outage in South Australia – a ‘black systems’ event. Tornadoes moved across the state between 3.00pm and 4.00pm, primarily in the mid-north – causing damage to 23 transmission towers and triggering the outage at 3.48pm.
Businesses and communities were significantly affected by the loss of power and destructive storm conditions; including powerful wind, large hailstones, heavy rain and flooding. Whilst power was restored to Adelaide and its surroundings within a matter of hours, large parts of the state were without power for several days.
Details of the storm, its impact and the timeline of events are contained within the independent review, commissioned by the South Australian premier on 4 October 2016.
