Rewinding ez2viewAustralia to 17:00 yesterday (Thursday 20th February) we can review another instance of the same instances of price volatility in Queensland – as shown here in this snapshot from the 17:00 dispatch interval, highlighting bid changes, constraints and other parameters of interest.
Whilst ez2view is designed to make the energy market more understandable, it’s important not to jump to conclusions with respect to the data shown here.
