Summary of entries received for 2008-2009
An overview of the final range of estimates received for the peak demand guessing competition of summer 2008-2009.
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.
Analysis of the FCAS market in Victoria over the 23rd July, 2008
On the 23rd of July, 2008 one of the HWTS – LYPS 500kV Line was down for maintenance when a second one tripped, leaving only one line remaining. This caused NEMMCO to declare the failure of that remaining line the greatest single contingency in the NEM, causing them to buy large amounts of FCAS from generators.
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).
September in the NEM (a review of 10 years of history)
One of 12 articles on the months past in the NEM. Here we examine the trends in price and demand across the NEM for September, and take a closer look at the effects of the 2007 drought on this particular month.
August in the NEM (a review of 10 years of history)
One of 12 articles on the months past in the NEM – in which we examine the trends in price and demand across the NEM for the month of August.
July in the NEM (a review of 10 years of history)
One of 12 articles on the months past in the NEM. Analysis of July has revealed that the peak NEM-wide demand for the past 3 years has occurred in winter – and has been significantly higher than the peak summer demand.
June in the NEM (a review of 10 years of history)
One of 12 articles on the months past in the NEM. June has brought us several cases of “economic witholding of capacity” – particularly in 2002, and in 2007 the NEM had a very interesting week in which the IRPM plunged to its lowest level ever.
May in the NEM (a review of 10 years of history)
One of 12 articles on the months past in the NEM – in which we examine the trends in price and demand across the NEM for the month of May.
April in the NEM (a review of 10 years of history)
One of 12 articles on the months past in the NEM. Here we present a detailed analysis of prices in each region of the NEM, for the month of April over the past 10 years.
March 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.
February in the NEM (a review of 10 years of history)
One of 12 articles on the months past in the NEM. February has seen multiple price spikes over the years often as a result of high demand caused by the summer heat, but also during times of surplus available generation capacity.
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.
