Further thoughts about Summer 2008-09 (the heatwave, bushfires, new demand peak, and blackouts)

Massive Demand, Huge Prices, Load Shedding and the Cumulative Price Threshold (and lessons learnt?)
Wednesday 28th January saw demand across the NEM jump to unprecedented levels, setting a new record of 34,843MW at 16:00 NEM time. On Thursday 29th January, we saw the demand increase still further, leading to prices that stayed high for much of the day (to the point where the Cumulative Price Threshold was reached in VIC and SA and price caps were imposed), and a relatively small amount of involuntary load shedding occurring in VIC and SA.
February in the NEM (a review of 10 years of history)
