After watching electricity spot prices in Queensland remain stubbornly high over the weekend, we invested some time today to assess the extent to which these price patterns had ever been seen before – in the 15 years of NEM history.
An extra-ordinary weekend in Queensland, where the mercury stays up and so does electricity demand and (as a result, plus with some help from other factors) so does price.
A record of a hot day that drove NEM-Wide demand to the highest level it has achieved (thus far) this summer. See this in context of historical maximum levels.
A snapshot of a day of contrast – with high demand in Queensland (temperature driven) and extraordinarily low demand in the south.
The mercury in Sydney topped the 40 degree mark today, but demand did not climb to the heights it achieved when it set the record 2 summers ago.
A preliminary look at a number of events that happened today, leading to prices spiking to the Market Price Cap in a number of regions, Demand Side Response being very active, and trading desks being very busy.

With a severe weather warning issued for much of Australia (with Sydney and Brisbane almost being the only exceptions) and lasting several days, it’s timely to look at what AEMO is forecasting demand to be in the week ahead.
Some analysis of the extent to which Demand Diversity (the degree to which peak demands in each region occur at different times) has changed in 15 years. If there are changes, it could be a factor at play in why peak demand has been changing.
A longer-term look at how summer (peak and average) demand has trended over the 15 years of NEM history to date.
A brief look at the demand shape on Christmas Day 2012, and how this compares to prior years.
Here’s our regular, annual and popular call-to-calculators for all those who’ve drawn the short straw and have to work on through the Christmas -to- New Year this summer season. Turn the tables on those off enjoying some summer sun, or skiing way up north by getting your entry in – with a chance to be anointed “Best Demand Forecaster in the NEM” and celebrate with your own new BBQ (or some other new prizes).
Some starting thoughts, about the extent to which increased wind farm output has been responsible in the drop in spot prices in South Australia from the high levels seen in 2008.
A record of a higher demand day in Queensland today
An interesting day in the NEM today, with prices gyrating across a wide spectrum, and across all four mainland regions – on the back of higher demand in Victoria and South Australia due to temperatures there, and supported by transmission issues and other factors.
Three images from NEM-Watch highlighting extremes of pricing in the Queensland region of the National Electricity Market today – illustrating the volatility, and hence the opportunities for Demand Side Response.
A brief look, during the day, of the effect that the Queensland heat wave is having on electricity demand within the state – and further across the NEM. It was a day of marked contrast in demand patterns in the north and the south.
A collection of articles about events that occur, and observations that are made, about summer 2012-13 in the Australian National Electricity Market.
Some quick observations about the price spikes observed yesterday on the back of high temperature-driven demand in Victoria.
A number of recently announced closures of (and cut-backs in) a variety of coal-fired power station units across the NEM (including Northern, Yallourn, Munmorah and Tarong) – claimed to be a result of carbon pricing – generated significant interest in the press, and interested us to open NEM-Review and have a look at longer term trends, and the extent to which that attribution might be true.
Placing some context around reports of a record share of electricity demand in South Australia yesterday being met by wind production.
