The volatility this morning in South Australia lasted from 23:50 last night through until 08:35 (i.e. looking just at prices spiking >$1,000/MWh).
Another spike occurred this afternoon at 16:15 (to $1,003.94/MWh). With low wind conditions persisting and imports from VIC significantly constraints because of the outage reflected in the ‘I-VS_050’ constraint set through until Saturday evening (but then back on 10th May), will prices bounce again as soon as the sun’s gone?
Here’s a snapshot from NEMwatch at 16:40:
The price has spiked at 16:50 as I hit publish, so more to follow … perhaps.
Why did small-scale solar drop off vertically at around 1600 hours but not large-scale solar??
