Summer 2005-06 saw Australians sweltering in temperatures 40 degrees and above.
In the National Electricity Market, this led to new peaks in demand and (given the tight supply/demand balance) delivered high (and volatile) spot market pricing.
Here we have compiled a weekly summary of events in the NEM over summer 2005-06.
In a week which is traditionally very subdued in the market, the NEM sweltered in temperatures in excess of 40 degrees and an exceptional NEM-wide demand (about 30,000MW) was recorded.
What made this demand peak more remarkable was that this occurred on a day when, traditionally, a large amount of commercial and industrial load would have been offline for the Christmas & New Year holiday.
This article was written prior to 2nd February and drew from the insights gained with our NEMforecastTM product to highlight the looming issue of the tight supply/demand balance forecast for 2nd February 2006.
The week started with commotion in Queensland, when the VOLL price ceiling was reached.
Further analysis revealed that this was due to transmission system events and the trip of several generation units within Queensland.
