Tesla says its batteries could fix South Australia's energy problems in 100 days

[QUOTE=download;51939612]Musk saying $250/kWhr to the guy who's offering to foot the bill is pretty deceptive then. It's pretty clear the guy wanted to know how much he's spending, not just the price of one component.[/QUOTE]
Who knows what price they will agree on. Let's see if they can make it happen. Obviously Tesla is willing to put their money where their mouth is.

I will give them kudos for that.
Musk will, no doubt, go down in the history books as one of the most innovative people of the 21st century. The man is a genius.
He wants 1 GWh now

Elon's spoken with the Premier, so it's looking good. It would be interesting to see how it goes.
Yes, lets showcase SA while we have the highest unemployment rate in the nation, and some of the highest electricity prices in the world.

SA suffered because of this foolish endeavour and now we have to spend big dollars on batteries (dollars that will be transferred to the cost of electricity) to get ourselves out of it.
There was no need to be the "first" in this endeavour and wind turbines sure as hell don't bring in tourists so what is there to showcase besides a dick measuring contest or virtue signalling?

Well with this you don't need to use those OCGT plants to react to demand, or shut down the more efficient plants. So shouldn't these batteries actually considerably reduce the price of electric?

That will depend on the price difference these batteries buy and sell electricity at. Given they're limited life devices and considering their high capital cost it's possible they will only sell electricity when the price is very high. If you're not selling electricity with a very high price difference you may exceed the batteries life before you've recoup the capital costs.
Either way, we wouldn't have needed the OCGTs or the batteries if our government weren't so insistent of the dubious goal of "most green Australian city".
We'll still need the OCGTs anyway, even the 1 GWhr battery won't be enough to significantly reduce our demand for OCGTs. 1 GWhr is only half an hour of demand.

Well they don't really need to sustain the whole grid like that. They can just smooth out the peaks and troughs of demand, giving time for more efficient CCGTs to react. Plus base load stations could keep running at slightly higher output when demand falls with excess power charging up the batteries.
It might not be enough to eliminate the use of OCGTs completely but it gives the much more efficient plants more time to react.
