Big apologies to our readers for this very short (and perhaps cryptic) article – easiest to post this now and (if time permits) return later.
One of the other wind farms that stood out (in part because of its larger size) when preparing the data for ‘From the 4-second SCADA data, a view of Production by Fuel Type on Tuesday 13th February 2024’ was the Moorabool Wind Farm.
Here’s the trend of the 4-second SCADA data for MOORAWF1, with all the other wind farms removed and some timings added:
That’s all for now.
The reasons for this are very clear in the market data – the output drops were Moorabool WF being constrained off by transmission limitations around Moorabool / Geelong, which preceded the 500 kV line trips (and worsened thereafter). The availability of the plant remained high until about 3pm, but in any case it was mostly constrained off from 12:40 NEM time onwards
Perhaps the Moorabool Wind Farm (and the Berrybank WFs) tripped on excessive wind speed at its location. This wind storm subsequently hit the 500kV towers causing their demise.
