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.
After watching electricity spot prices in Queensland remain stubbornly high over the weekend, we invested some time today to assess the extent to which these price patterns had ever been seen before – in the 15 years of NEM history.
