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.
A look at the trend towards deeper liquidity of trading of electricity derivatives in Australia’s National Electricity Market (NEM).
Some observations about the longer-term trend of electricity production, across the NEM, aggregated across all states by fuel type. This reveals some of the trends that have been developing in recent years prior to the introduction of the carbon tax.
A snapshot of an instance of the Queensland regional constraint, which has returned after an absence over the autumn months.
A brief look at the significant increase in output from hydro plant coincident with (and slightly preceding) the introduction of the Carbon Tax
A quick look at the extent to which wind supplies (across all wind turbines in the NEM) are diverse enough for supplies to have a degree of dependability.
Following some questions yesterday (from clients and others) we take a quick look at how Yallourn Power Station is progressing in coming back from outage caused by inundation from the nearby river.
The range of questions we’ve been asked over the course of the past 2 weeks (since the introduction of the Carbon Tax) seem to resolve to these 3 key questions.
Now that we’re through the first week of Australia’s new Carbon Tax, we thought it would be of interest to have a look at whether there has been any significant…
