    I hope the Heywood interconnector isn't affected, as I have family in SA
    .
    SA has been a net exporter of power for months, especially since Vic lost three "reliable" generating units recently to unexpected faults.

    Anyway, no need to worry about SA, a lot of work since last year has made the state's power supply much more robust, the interconnector is just the device with which good neighbours can help each other out. And Here is SA's power outage map, you can see if your friends still have power.

    Oh oh. Paywall.

    Wild weather in South Australia has brought down power lines and triggered blackouts in the communities around the state’s Tesla battery on the day it was switched on.

    Data from SA Power Networks has revealed 208 homes in areas around the battery will be without power until as late as 11pm tonight after wild weather and more than 250,000 lightning strikes overnight felled power lines and cut supply.
    Parts of Jamestown, where the Tesla battery is located, and around a dozen surrounding communities including Hornsdale, Caltowie, Canowie Belt are without power, with the network operator putting the outages down to storm activity and equipment breakages.
    The outages come as the Weatherill government flicked the switch on the world’s largest lithium-ion battery on Friday for the first time.
    The $50 million battery which stores energy from the nearby Hornsdale wind farm has been billed as a stopgap for the state’s energy supply, and can power up to 30,000 homes for over an hour in the event of a major blackout.
    A spokesman for the Premier told The Australian that the nature of the storm damage to the transmission lines meant that the battery wouldn’t be able to power homes because equipment needed to be repaired to reconnect the homes to the grid.
    Some parts of Jamestown will be back up online by 9pm tonight, and suburbs around the Canowie Belt were expected to be back up and running by 5pm this afternoon. Stone Hut and Laura will have power before midnight.
    The Elon Musk-designed battery forms the showpiece of the Weatherill government’s $550 million energy plan, which uses diesel generators alongside existing conventional coal-fire and gas power and the state’s wind and solar farms to keep the lights turned on.
    More to come ...

    Yup, storms knock out above ground grid infrastructure. Shoulda got Musk to underground thousands of km of HV wires while he was there.

    Looks like someone forgot to gold plate the network connection to the new battery
    By all means get a Defender. If you get a good one, you'll be happy. If you get a bad one, you'll become a philosopher.

    There is plenty of above ground power supply in the Pilbera, Kimberlies and the NT and yet it doesnt get destroyed by far more severe weather.
    Maybe it isn't the construction type that is causing problems it may be that the construction qualiy/strength is the problem down south

    Most of the local infrastructure around the wheat growing area near Jamestown is 50+ years old and feeds a lot of farms and small towns in an area not used to giant tropical storms, unlike the Pilbara. At least it's not hard to stand up again.

    A few years ago I was driving up that way and saw a "wall of death" storm studded with continuous lightning flashes bearing down on the road I was on. A quick skedaddle later I arrived at our friend's place to find the power was out. The next day I went back down the road and about 2km of local 11kV feeder line was lying on the ground with multiple smashed poles. Nothing short of undergrounding can stop that sort of thing.
