Tassie hits the Cumulative Price Threshold
For only the third occasion in the 10 1/2 years that the NEM has been operational, the Cumulative Price Threshold (CPT) has been reached. Yesterday evening, the CPT was reached in the Tasmanian region.

We noted yesterday (Wednesday 10th June) that NEM-wide demand climbed past 32,000MW for the first time this winter.
The following evening saw demand climb to similar levels (a peak of 32,054MW at 18:20 – so 35MW higher than the previous night). However the situation on Thursday night was different in two key ways…
On Wednesday 10th June 2009, temperatures plunged across the NEM for the first time this winter, providing a long-awaited dump of snow to start the season, and driving electricity demand high.

Wednesday 28th January saw demand across the NEM jump to unprecedented levels, setting a new record of 34,843MW at 16:00 NEM time. On Thursday 29th January, we saw the demand increase still further, leading to prices that stayed high for much of the day (to the point where the Cumulative Price Threshold was reached in VIC and SA and price caps were imposed), and a relatively small amount of involuntary load shedding occurring in VIC and SA.
On 19th January, high prices were sustained in SA for several hours, bringing the Cumulative Price within a whisker of the $150,000 threshold, at which prices would be capped.

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).

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.

It appears that we spoke too soon when we mentioned on the 22nd July that winter 2008 had been relatively uneventful.
Just over 24 hours from making these comments, we saw prices jump sky-high in the mainland regions, and go the other way (to the negative price cap) in Tasmania.
