Articles on various stand-out events happening in the National Electricity Market in Autumn 2010.
Just after midday today (Wednesday 21st April) South Australia and Victoria experienced some high spot prices. Here’s a quick post to highlight what happened.
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).
Now in its 4th year – Earth Hour has continued to spread across the globe, but participation in Australia appears to have decreased from previous years. In this article we compare reported electricity savings during the past 4 Earth Hour events, and look at the effects of Earth Hour on the NEM in 2010.
Some analysis prompted by a short article in the AFR talking about a reduction in emissions over summer 2009-10 (with the possible implication being that emissions have turned the corner).
As was mentioned in a previous post the topic which was most topical was the topic of increasing distribution network charges. The Queensland price increase proposals have not been approved yet, but based on the history of New South Wales, there is a widespread expectation that they will get approved.
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.

More high temperatures in South Australia and Victoria this afternoon have driven the demand and the spot price high.
