Future of the Australian Electricity Market

Best and final.. Hopefully!


I had a long conversation with a dealer about the rebates etc. for heat pump water systems. Federally there are STC's available, based on various criteria (size, location etc.). In NSW there are ESC's available, based on much the same criteria but also what technology is being replaced (and the caveat that the old heater MUST be taken away or otherwise made incapable of working - it's a "replacement" not an addition). Those are the available discounts in NSW. Depending on the fine details, they come out at somewhere around $1800ish. The value of both STC's and ESC's can change.

The $33 heat pump is the combination of the discounts above and a really really cheap heat pump system, many are rebadged versions of the same thing. Allegedly they are quite noisy, and the warranty is only three years.

This sand battery could be interesting:

Although touted as a commercial installation, it seems a little on the small side to me. If they can keep it hot in Finland, I don't think we would have much trouble here.

I couldn't see any info at all in that link Paul, apart from the pic, so I went looking.

(except he thinks they should be heated up from cheap power at night, rather than solar power, which is a bit odd)

And from the BBC:

Try clicking on the pic. I think it will take you through the slides.

Not wishing to be seen as unduly biased (actually everyone of us is biased) I thought I would include this "spin" on just how good the nukes are:

15 interesting facts you didn’t know about nuclear energy (msn.com)

Interesting. for example, as how forgetful they can be when they say there have only been two major accidents: Did they forget Three Mile Island ? It was on their own shores.

I would be interested to know who actually sponsored this article and indeed forum members own thoughts.

Clearly Three Mile Island doesn't count as a "major incident", and I seem to remember something going seriously awry at Windscale in the UK many years ago?

"I once absent-mindedly ordered Three Mile Island dressing in a restaurant and, with great presence of mind, they bought out Thousand Island dressing and a bottle of chilli sauce" - Terry Pratchett

Mr Brush.

Clearly that is the implication as it was not deemed a catastrophe. However, it was in a heavily populated area and this is the sobering thought I took from this incident, which we now know as "minor."

"Cleanup at TMI-2 started in August 1979 and officially ended in December 1993, with a total cost of about $1 billion (equivalent to $2 billion in 2022)."

and this

"TMI-1 was restarted in 1985, then retired in 2019 due to operating losses. Its decommissioning is expected to be complete in 2079 at an estimated cost of $1.2 billion"

PS: Call me skeptical, if you wish, but it could just be why nobody wants one in their backyard.

Very expensive to build, and exceedingly expensive to decommission. The future decommissioning costs would likely be multiples of those figures.

I don't see how large scale nuclear can ever compete with adding storage (battery/hydro) to renewable generation. There may still be a place for Small Modular Reactors (SMRs), but the technology has been "coming soon" for quite a while now.

While it is not a secret, it seems to be a little-known fact that there is a nuclear reactor in Lucas Heights, Sydney. It is not for production of electric power but has been there since 1958 producing medical isotopes and being used for research purposes.

Back in the late 1970's or early 80's, (a long time ago so I'm not sure of the year) a lot of military personnel in the Sydney area, particularly Transport drivers, were put on emergency standby in case they were needed to evacuate selected people (Read VIP's - politicians etc) fron a location in Sydney.

Because of my position in Defence at the time, I also became aware that there had been an "incident" at the Lucas Heights reactor that coincided with this. Join the dots ... :rolleyes:

Nominally the Lucas Heights reactor is 5MW, but as you said, it does not produce electricity. When it was first commissioned, my understanding is that there was very little housing around, but nowadays it is in the middle of suburbia and a constant source of complaint from the residents.

I suspect that most "incidents" are covered up to prevent the populace freaking out. Only the big ones that cannot be covered up become general knowledge. The safety people would point to the triangle of incidents.

Well this would have happened around a decade before the Simpsons were a thing. Maybe the creators of the Simpsons based Homer's character on some unfortunate clumsy misfit who worked at Lucas Heights. I guess we will never know.

They have had their share of minor bungles in recent years, not just the earlier (and possibly more serious) incident you were referring to:-

Paul: I assume that that is a quote from a government agency. When did any government agency bring in a project on time and under budget? Frequently both get blown, sometimes spectacularly.

And there were also some incidents (plural) where they actually lost nuclear bombs.

Helpfully, the infallible Wikipedia has published a fairly comprehensive list of nuclear incidents - it is a little longer than I expected.
