… so who won the competition for summer 2011-12 as “Best Demand Forecaster”
Demand was lacklustre but we’ve still given an impressive BBQ away to our competition winner for this summer….
Recapping NEM-Wide demand (or the lack thereof) over summer
Some summary points about how NEM-Wide demand across the NEM over summer 2011-12 was surprisingly low, with a very low peak achieved.
Yes, the demand did peek above 30,000MW
Looking further (after making the first post today) I see that the demand did rise above 30,000MW across the Australian National Electricity Market today – still a very low level for the highest demand so far this summer…
Hot in VIC and SA – but demand not climbing past the green zone
High temperatures in Victoria and South Australia – but demand is still well down on the all-time records for those regions.
No joy for generators as demand stays low
NEM-wide demand is still to crack the 30,000MW barrier (which used to be fairly commonplace several summers ago). This is not providing good news for generators.
Summer continues, but demand has not (yet?) arrived
By now our schools are full again, and businesses are back at work – so it is timely to review how electricity demand in the NEM trended through the holiday months of December and January.

Hot day in QLD drives regional demand close to the record
The temperature reached 34 degrees in Brisbane today – with thunderstorms predicted to sweep through the south-east corner, bringing with them a cool change and localised disruptions to power supplies. In the following snapshot from NEM-Watch (at 14:05) we see…
North Queensland Powers down with TC Yasi underway
As the Courier Mail tweets that 89,000 people in Townsville and Cairns are without power as TC Yasi approaches, I thought the following chart (taken from our ez2view application) might explain a bit of what that means: Like everyone else,…
The extremes continue in the NEM
More extreme weather drives extreme demand and extreme prices – on Wednesday 2nd February.

A very modest start to summer peak demands
Some quick notes about how levels of demand are, so far this summer, much lower than they have been in recent years.
Demand Side Response in NSW on 4th February
On the 4th of February at around 11am energy users in NSW appear to have curtailed their load in response to high prices, resulting in a significant drop in demand. Simultaneously, network conditions and generator rebidding caused the NSW pool price to jump back and forth between extreme prices close to VOLL ($10,000/MWh) and the Market Floor Price (-$1,000/MWh).
