Ten years on, South Australia's statewide blackout still fuels electricity debate

On September 28, 2016, at about 4pm, electricity supply to more than 850,000 properties and approximately 1.7 million residents was disrupted, leaving South Australia in darkness. The blackout was caused by a severe storm that had been brewing for days.

Tom Koutsantonis, the state's energy minister at the time and again today, was in parliament moving legislation relating to the National Electricity Market when he noticed the chamber's doors glitching. "I heard the magnets in the parliament [doors] release and all the doors suddenly open or close, depending on their position," he said. Suspecting a brownout, he was then told the situation was far worse.

Energy industry analyst Danny Price was monitoring conditions closely. "I just saw demand drop off a cliff, so I knew straightaway it was a blackout," he said. "I wasn't surprised. I was watching the weather in South Australia for a day or two beforehand. You could see a very big storm was brewing."

While supply was slowly restored over the coming hours, some parts of the state were without power for more than two days. An early estimate concluded the blackout cost businesses more than $360 million.

The article notes that a decade on, the electricity debate is still live, and the energy minister who presided over the blackout is back in the portfolio.

Analysis

Why This Matters

The blackout remains one of the most significant events in South Australia's recent energy history and is likely to keep being cited in debates over grid reliability and the clean energy transition.
It is a reminder of the real-world consequences of extreme weather on essential services, and the economic cost such events impose.
With the same politician again holding the energy portfolio, the anniversary links past lessons to current policy responsibilities.

Background

The September 2016 blackout was one of the biggest tests of South Australia's electricity grid. At the time, the state had been at the centre of national arguments about energy policy, and the outage became a reference point in discussions about how to maintain reliable supplies while shifting the generation mix. A decade on, those questions have not been settled.

Key Perspectives

Tom Koutsantonis (SA Energy Minister): He was inside parliament when the outage struck and admits his first instinct, prompted by glitching doors, was that it was a brownout. His role then and now gives him a personal connection to the event's legacy. Danny Price (Energy industry analyst): He saw the storm coming and was unsurprised when demand collapsed. His account emphasises the natural forces involved, and he was focused on the forecast in the days beforehand. Critics/Skeptics: The source does not include direct comments from critics of current energy policy, but it notes the electricity debate remains live. The blackout is likely to remain a contested case study in arguments over the reliability of South Australia's electricity supply.

What to Watch

Whether the anniversary prompts public statements from state or federal politicians about grid security and energy policy.
How South Australia's system responds to the next major storm and whether lessons from the 2016 event have been applied.
Whether new assessments of the economic cost or the long-term business impact of the blackout are published as part of anniversary coverage.
