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.
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.
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).
