Might see more price volatility this week … at least in QLD?

Following the last few days, it’s beginning to feel like more of a ‘normal’ Brisbane summer – with hot, humid weather and the promise of afternoon storms.  The outlook this week appears to be for more of the same:


With schools and industry back from holidays, we might start to expect this to flow through into levels of demand, and hence into price volatility (as noted earlier, it’s been a bit of a flat start to summer … at least in terms of demand and spot prices).


(A)  Forecast for the week ahead, NEM-wide

So I took a quick look at the forecast for the week using the 14-day trend of NEMwide demand that’s published for broader consumption in our ‘Dashboards’ application:


As highlighted in the note, we’re still not seeing any forecast for ‘Market Demand’ to reach 30,000MW … remembering that:

1)  this was almost an everyday occurrence in summer days of 10 years ago.

2)  … and that it would be beyond this point (e.g. 33,000MW or 34,000MW or 35,000MW) that ‘peak demand’ would get really hairy from a supply-demand perspective and we’d see sustained multi-regional volatility.


(B)  Forecast for the week ahead, in QLD

Flipping just to look at the QLD region we see that the coming week is probably going to be a bit more interesting from a regional perspective – with Market Demand on Friday currently forecast to be up towards 10,000MW.

Will see what the week unfolds…

  1. Bit ironic that on 3rd Feb this year consumers could be facing yet another very expensive RERT bill. On 1st Feb last year AEMO forecast a Queensland demand over 10,000 MW and it cost Queensland consumers a whopping $50 million for the period 1700 hours to 2130 hours.
