Some quick notes today, on day #2 of the Carbon Tax, prompted by some prices that jumped all around the place (not so much due to carbon, though).
It’s the first day under the new Carbon Tax regime, so worthwhile to have a quick look at early indications of how spot prices have changed in the NEM.

A brief summary of NEM-wide demand this winter

Some quick notes, and images, of a price spike in TAS this morning.
Inspired by the price spike experienced this evening, I have spent a little time to put together the background to winters in the NEM.
This will be useful in understanding the context of any other events that occur this winter, and are analysed on WattClarity.
A quick overview of how the daily peak NEM-wide demand trended over winter 2009, in relation to our forecasting competition.
Some preliminary analysis of what happened on Thursday 11th June 2009 – when the NEM experienced its highest NEM-wide demand this winter.
This weekend, we have prepared this analysis of the entries we received for our “Peak Demand Forecaster” competition for winter 2009.
In conjunction with this analysis, we thought it would be of interest to also incorporate this chart (generated from a BETA version of the NEM-Review v6 software package) to highlight how the peak NEM-Wide demand unfolded over the previous winters…
We reported previously that a price cap was invoked in Tasmania on Tuesday 16th June because the Cumulative Price Threshold was reached. In official terminology, this was an Administered Price Period (APP). At 04:00AM this morning, NEMMCO released a market notice advising the market that the APP had been lifted…
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.
The “Who’s the Best Demand Forecaster in the NEM?” challenge for winter 2009. Tell us the peak demand for this winter by 9AM Monday 29th June, and win your choice of espresso machine.
For those who weren’t aware, Winter 2009 has seen us offer our “Who’s the Best Demand Forecaster in the NEM” challenge – as a chance for the market to redeem itself, following what happened in summer 2008-09 (when the market surprised us all).
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…
Miscellaneous articles on activity in the NEM during winter 2009.
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.
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.
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.
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.
