Summer 2009-10 in the NEM

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).

On the 2nd and 3rd of February this year prices spiked in South Australia and Victoria in the afternoon. Coinciding with these spikes, the Tasmania pool price went negative, close to the Market Floor Price (-$1000/MWh). In this article we take a look at the effects and possible causes of the negative prices.
