It costs three or more times as much since you need to use uncommon materials and design from scratch.
>And as for distances - power grids have been built at similar scale, and even longer.
There is no country in the world as large and as sparsely populated as Australia. The distance between Perth and Brisbane is the same as that between NY and SF with no one living between them. When I worked in finance here it was always fun explaining to Americans why their algos will fail regardless of what we do, the speed of light matters.
Hilariously enough, even the US doesn't have one grid continent wide, and it's ten times as densely populated as Australia.
Russia is an example of a country that is much larger, and also sparsely populated.
And I'm still confused - what kind of "uncommon materials" are we talking about? What exactly is the problem with normal power delivery infrastructure that precludes it from operating at high temps?

That said, it looks like it's just a couple percent, so maybe you just overbuild a little.
Solar panels are also less efficient when it's hot, but these are all just losses that can be overcome by throwing more panels at it. If you have a giant desert, it's basically free energy for the taking - you just need to make that initial investment. And unlike e.g. Sahara, there's well-developed infrastructure around the desert, nor are there issues with political instability.
