"blown up by the previous government" should read, blown up by the previous Labor government. I probably made the blue because the Liberal government between the last Weatherill Labor government and the current Malinauskas Labor government was so useless as to be easily forgotten.

A realistic assessment of the situation by someone who knows rather than just some academic "expert" !
Our leaders would be well advised to listen to this man.

Very interesting article.
I doubt Chris Bowen would read it. It is probably over his head.
Bowen said recently that they have to install 22,000 solar panels a
day for the next 8 years. He also said they have to install 90 wind
turbines a month for the next eight years.
I am sure he believes that. That belief if I was PM would be enough
to sack him from the job.
I have had experience in organising a very small group of techs to
undertake work well away from the workshop in the country.
Someone has to organise the frames on which the panels are mounted.
Some factories are to produce the steel work, get the land cleared
and start assembling the frames and concreting them into place.
In all the days that operating takes, remembering they are all over the
country and semi trailers have to be organised to get the right number
of frames to each site wherever it might be.
All these days means 22,000 panels per day were not mounted so they
have to be added to the 22,000 a day.
The teams organised in the country to mount these 22,000 a day have to
have transport and accommodation organised to start mounting these
panels which semis will have to be organised to deliver at the preset rate.
Then the electrical people have to follow on connecting the panels
to the wiring someone has installed between all the frames and to a
site control hut.
Anyone that believes that can be done in eight years should be sacked.
The possibilities of cost over run is astronomic.

ttbn,
>Our only coal powered electricity supply was blown up by the previous government,

No it wasn't. The three economically unviable coal fired power stations at Port Augusta were demolished by McMahon Services, and it was Flinders Power not the government which commissioned them to do so.

>and the current government has guaranteed the gas one only until 2026.

Which gas one? There's lots of them!

>That leaves only the interstate interconnecter,

Two of them (1 large, 1 small) plus another (large) one under construction.

>the failure of which plunged the state into darkness not so long ago.

...resulting in measures implemented to ensure that can never happen again. Since then our electricity supply has been the most reliable in the nation.

Nuclear power won't make us world leaders in cheap reliable energy, but renewables probably will. And if Albo's calling the premier "Mali" he's probably just following the 'tiser's lead.

Does anyone have a figure on how many panels can be mounted in a day
and connected to existing wiring by, say 2 men, in a day ?
Do that and you can calculate the cost of living away salaries to
mount 22,000 panels a day. err plus the ones that have not been mounted already !

Bazz,
Does anyone have a figure on how much pollution the manufacture of these panels causes & how much pollution from disposing them ?
