Record summer demand in NSW yesterday!

NSW experienced a record summer demand on Thursday 15th January, driven by high temperatures across the state. The extreme weather experienced in NSW followed the extreme weather that swept across South Australia and Victoria only two days beforehand.


A hot day in SA yesterday, and prices soared!

Just as had been forecast, Tuesday 13th January 2009 saw hot, dry weather roll in across South Australia, and then into Victoria. The high temperatures caused demand to climb, but not to the level at which NEMMCO had forecast demand to climb over the summer period. As a result we saw the price in SA jump to a level near VOLL at 13:40, and remain there until about 18:00 (i.e. more than 4 hours).





June in the NEM (a review of 10 years of history)

One of 12 articles on the months past in the NEM – covering notable events of March, such as the unforgettable South Australian heatwave of 2008 which caused the Cumulative Price to reach the Cumulative Price Threshold for the first time in our memory.



January in the NEM (a review of 10 years of history)

One of 12 articles on the months past in the NEM. For January we revisit events such as the fires at Moomba in 2004 (which curtailed gas supplies from central Australia); and the blackout on 16th January 2007 which drove the price to VOLL in Victoria.
