Re: Australian government approves AAPowerLink project to export solar to Singapore
#12Does it actually make economic sense to run a cable large enough for that kind of power from Australia to Singapore? I would have guessed there must be enough domestic customers or in Indonesia that would make more sense.
Indonesia probably has enough land for its own panels.

#13Eh, Factually correct (the best kind) but to be a little more specific: > "... Renewable energy developer Sun Cable has secured approval from the Australian government for the Australian element of its Australia-Asia Power Link (AAPowerLink) interconnector. ..." So they have licence to make the PV farm, and to cable it to a head-end, and to run HVDC to the edge of Australian Exclusive Maritime Zone. What happens afte…
Edge of its exclusive zone is still 200 miles away from its coastline. That’s no joke though it only about 10% of the way to Singapore.

#14Can someone explain how this makes sense economically, isn't it really expensive and lossy to transport electricity such a long distance?
You double the voltage and halve the resistance. With longer cables you can invest more in more expensive stuff at the ends to deal with the high voltage.

yeah - dumb question from me as well. won't a lot of power be lost during transmission ?
What material would they use for the cables at those vast distances to make the numbers work ?

Realistically the first big sell is Indonesia. No cable to Singapore will make sense but it transits Indonesian waters and you would think a willing buyer and seller is there. Shorter path so less transmission losses.

Singapore with a native population of about 4 million has reserves of about $1 trillion.
They can afford to splurge to claim green/net-zero status.
Shopping calculations for them need not be about economic cost benefit analysis.

#18The render of the planned solar panel array looks like sci-fi art. Very cool (hot?). Maybe there are already vast fields of solar panels like that, and I just haven't seen it before?
There are actually already fields like that. Look at the ones in China or the US. Scaling it up is the next step.

I'm unsure about Indonesia, but domestic customers in that region would be pretty limited. The closest major power users would be in Queensland (>1000km) away.
Data Centers, Green Steel production. Power == Opportunities. This is such a massive win for the environment.

Aussie politicians are too busy propping up coal and proposing unrealistic nuclear solutions to seriously focus on renewables.
