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 change in dispatch patterns across the NEM as a result….
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.
An assortment of articles covering events happening during Winter 2012
Some brief analysis of the floods at Yallourn Power Station.
Demand was lacklustre but we’ve still given an impressive BBQ away to our competition winner for this summer….
Some summary points about how NEM-Wide demand across the NEM over summer 2011-12 was surprisingly low, with a very low peak achieved.
An article recently in one of the main papers about increased flows down the Snowy River prompted the question, internally, about how much the La Nina pattern of the past 24 months had impacted on production volumes from the hydro facilities around the NEM.
A quick look at the demand levels on Saturday 25th driven by hot weather in VIC and SA. What would have happened had this been on a weekday?
Looking further (after making the first post today) I see that the demand did rise above 30,000MW across the Australian National Electricity Market today – still a very low level for the highest demand so far this summer…
High temperatures in Victoria and South Australia – but demand is still well down on the all-time records for those regions.
NEM-wide demand is still to crack the 30,000MW barrier (which used to be fairly commonplace several summers ago). This is not providing good news for generators.
By now our schools are full again, and businesses are back at work – so it is timely to review how electricity demand in the NEM trended through the holiday months of December and January.
A quick look at how NEM-wide demand has trended so far this summer (to define the starting point for our competition entrants).
This brief look raises questions about the demand seen in December 2011, so we compare against previous years.
