2 Commentson "South Australia hit by two price spikes"
Demand spiked, Angaston (diesel) dropped 37 MW, and Ladbroke (gas, price setter) was constrained down due to network limitations. Wind dropped 5 MW the first event and 18 MW the second time. Small changes compared to diesel and demand.

What caused the spike in price? Was it a fall in wind production?
