Hornsdale Wind Farm starts up at time in South Australia when every MWh matters

Watt Clarity

With plenty of media (and particularly social media) coverage of initial generation at the Hornsdale Wind Farm in South Australia over the past week or so, I grabbed a short break in my schedule to power up NEM-Review and produce this quick trend in the output of Hornsdale compared with the aggregate output of all wind farms across South Australia:

SA june

As we can see (when included on the same scale) it’s clearly early days for the Hornsdale plant, with output so far barely peaking above 10MW for particular half-hours.

When fully commissioned over several stages, peak output will be orders of magnitude higher than current output.  From memory 2 stages are confirmed proceeding already – but I think there might also be plans for more?  Perhaps one of our readers can provide further information in a comment below?

Back to current NEM machinations, however – in the chart above we can see how generation (from any source available) cannot come a moment too soon, however, for a region facing a very volatile period currently as a result of multiple factors – including planned transmission outages severely limiting imports from VIC, low wind, and (coincident, and related) high gas prices.

Coincident (but increasingly related) variables that are an illustration of the challenges we’ll face as the broader energy transition I spoke about here continues.

    But won’t Hornsdale’s output go to the ACT?

      Not physically (because of the laws pf physics), but commercially (because of the PPA in place). I understand the confusion that the two different types of targets can create, however.

    Neoen announced announced financial close of the next 100MW (Hornsdale 2) at the end of June, so that’s confirmed as proceeding.

    There are two 100MW stages contracted to the ACT government. The whole project, as originally announced, was up to 270MW. http://ramblingsdc.net/Australia/WindSA.html#Hornsdale_Wind_Farm

      Thanks David!

    How does this work when connected to the grid? The wind farm output obviously cannot match demand. Therefore it must rely on a backup source of power. Is the wind farm generated electricity displace baseload power making the back-up power source the swing producer, or the other way round?
