It seems I keep stumbling upon hooray stories about Australian grid batteries. I found this reneweconomy article about a new Tesla battery that will be built in New South Wales. The article is titled “Transgrid to build Australia’s first Tesla Megapack big battery in western Sydney” and the author is Giles Parkinson. I remember him from a cheering and one-sided article about the Hornsdale Power Reserve and this article seems not much different.
The first paragraph provides the crux of the story (my emphasis):
Transmission company Transgrid is to build the first big battery in Australia using Tesla’s recently introduced Megapack battery technology, and what is likely to [sic] the first of more than 10 big batteries to be built across NSW as it they are important in face of the looming retirement of its ageing coal fleet..
A new big Tesla battery will be built, this time in New South Wales and likely 10+ big batteries will follow. More, these batteries are built in preparation of the retirement of the New South Wales coal power plants over the next 10 to 12 years…
This all sounds pretty impressive, but I wonder what order of magnitude we are talking about here.
