NEM-wide demand races past 31,500MW today
A record of the highest NEM-wide demand so far during summer 2012-13. A useful reference, for all of those who entered our “Best Demand Forecaster in the NEM” competition this time, and for those who sat on the sidelines.
How extraordinary have Queensland’s recent electricity pricing patterns been?

NEM-Wide demand peaked above 31,000MW on Friday
A record of a hot day that drove NEM-Wide demand to the highest level it has achieved (thus far) this summer. See this in context of historical maximum levels.
Queensland’s turn to sweat today, but NEM-wide demand plummets
A snapshot of a day of contrast – with high demand in Queensland (temperature driven) and extraordinarily low demand in the south.
Not even 41 degrees in Sydney today can drive demand close to a new record
The mercury in Sydney topped the 40 degree mark today, but demand did not climb to the heights it achieved when it set the record 2 summers ago.

Prices see-saw across the (mainland) NEM today
An interesting day in the NEM today, with prices gyrating across a wide spectrum, and across all four mainland regions – on the back of higher demand in Victoria and South Australia due to temperatures there, and supported by transmission issues and other factors.
An illustration of the nature of dynamic wholesale electricity prices in Queensland today
Three images from NEM-Watch highlighting extremes of pricing in the Queensland region of the National Electricity Market today – illustrating the volatility, and hence the opportunities for Demand Side Response.
A stinker today in southern Queensland, leading to high demand and prices on the tipping point
A brief look, during the day, of the effect that the Queensland heat wave is having on electricity demand within the state – and further across the NEM. It was a day of marked contrast in demand patterns in the north and the south.
Prices soar as the south-east sizzles – with summer arriving early
