The biggest impact on SA power prices right now is the wild price fluctuations, because the power price ceiling is $23,000 and the floor is -$1000 it means that it only takes a few hours at the ceiling to completely blow average prices up
And sadly we won't be able to write this article at the end of the summer quarter because SA had a major heatwave that lasted a week:
South Australia endures record-breaking heat
Minimum of 34 degrees overnight

Which meant a boatload of air conditioners on 24x7 which meant a ton of power draw on the grid so it maxed out for ages

So yeah a painful one coming up
