We’ve not had any time to delve into this, but thought it worth flagging with this snapshot from NEMwatch at the 16:15 dispatch interval (NEM time) on Tuesday 5th November 2024:
We were alerted to the two significant drops noted in successive dispatch intervals by alerts configured in the ‘Notifications’ widget within ez2view:
1) ‘Market Demand’ dropping from 1,203MWat 15:15 to 973MW at 15:20 (down 230MW)
2) then dropping further to 700MW at 15:25 (down 273MW)
3) and further still to 610MW at 15:30 (down 90MW)
4) to the bottom point of 493MW at 15:35 (down 117MW)
… so down 710MW (or 60% of the initial value) in 20 minutes
My first guess is something happening with cloud cover and rooftop PV?
… but we’ve dug no further.
Yes, I live on the Eastern most edge of Adelaide, and that last time slice would be when the sun hit my panels, after the rain departed.
