Some analysis of how NEM-wide demand trended through summer 2010-11, and what this meant on a regional level.
high NEM-wide demand
An illustration of the high demand and volatility on Tuesday 1st February.
Some snapshots of a day in which NEM-wide demand soared, driven by high temperatures across the middle of Australia.
A listing of some drivers for higher (and, in some cases, lower) prices in the wholesale spot component of the NEM.
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 snapshot of a higher demand day in NSW, driven by higher temperatures as they move eastwards
Some notes about the heatwave in SA and VIC, and what it means for the NEM
Some quick notes on what’s happened in the NEM today (17th) and yesterday (16th)
Some further analysis of the MT PASA and ST PASA forecasts for other regions of the NEM (SA, TAS, NSW and QLD) for the day of 29th January 2009 – when a new record NEM-wide demand was established.
A few snapshots and quick notes about a very hot spring day in the NEM, with demand soaring, IRPM dropping across the market, and prices at VOLL in NSW
A few brief notes about a hot day across the mainland, with demand levels high in each of the 4 mainland regions
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.
A snapshot towards the end of a remarkable day in August 2009 when temperatures soared in South-East Queensland (yes, that’s in winter).
Summer 2008-09 is now well behind us, and there are a number of official reviews underway that will report back at some stage. Even so, we’ve been continuing to ponder a couple of things about what happened in January 2009…
We saw a massive new peak for NEM-Wide demand set on 29th January 2009, which surprised many (including us).
We return to that data and, by comparing with the previous 10 summers, see whether it should have been entirely unexpected.
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…
A couple of weeks ago, we opened for entries in our “Best Demand Forecaster” competition – run for the first time during winter.
Entries closed on Monday 29th June (2 weeks ago now) but we have only just found the time to do some analysis of the entries we received, which we have summarised in the following graph…
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).
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.
