How has the Carbon Tax influenced Hydro Generation levels?
A brief look at the significant increase in output from hydro plant coincident with (and slightly preceding) the introduction of the Carbon Tax
Yallourn is limping back into service
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.
3 Questions we’ve been asked, following the introduction of the Carbon Tax
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.
One week into the Carbon Tax – how have emissions changed?
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….
A very volatile day in VIC and SA (not particularly due to the Carbon Tax)
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).
First day under the carbon tax – how have spot prices changed?
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.
Flooded Yallourn turns Victoria to an importer
Some brief analysis of the floods at Yallourn Power Station.
Recapping NEM-Wide demand (or the lack thereof) over 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.
A hot Saturday could have driven demand higher – but how much?
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?
Yes, the demand did peek above 30,000MW
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…
Hot in VIC and SA – but demand not climbing past the green zone
High temperatures in Victoria and South Australia – but demand is still well down on the all-time records for those regions.
No joy for generators as demand stays low
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.
Summer continues, but demand has not (yet?) arrived
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.
How has demand trended, so far this summer
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.
Queensland demand continues to climb – towards the all-time maximum
Some snapshots of the market this afternoon, focused on the QLD region as demand continues to climb on a hot day this summer.
What happened to demand, this winter?
A brief summary of NEM-wide demand this winter
First price spike of Winter 2011
Some quick notes, and images, of a price spike in TAS this morning.
Analysis of demand over summer 2010-11
Some analysis of how NEM-wide demand trended through summer 2010-11, and what this meant on a regional level.
Hot day in QLD drives regional demand close to the record
The temperature reached 34 degrees in Brisbane today – with thunderstorms predicted to sweep through the south-east corner, bringing with them a cool change and localised disruptions to power supplies. In the following snapshot from NEM-Watch (at 14:05) we see…
