South Australian blackout

Right-wing politicians have blown hard on the anti-renewables dog-whistle since February 8, when extreme temperatures in South Australia were followed by rolling electricity blackouts.

Late that afternoon, power demand in the state spiked to near-record levels. From about 6pm, 100 megawatts — roughly 3% of the state’s total demand — was shed for about half an hour.

Yes, climate change was right there in the picture when a massive storm cut off power supplies throughout South Australia on September 28, forcing electricity workers to carry out a first-ever “black start” to get the state’s grid operating again. Estimated as a one-in-50-years occurrence, the storm left high-voltage transmission pylons bent like paper-clips.

Power is gradually returning to South Australia after wild storms blew across the state last night, but some areas could be offline for days. The storm — associated with heavy rain, lightning, and severe winds — damaged transmission lines that carry electricity from power generators to people, causing a state-wide blackout.

South Australian premier Jay Weatherill told ABC radio “the system operated as it was meant to operate”.
