....it is intended to sustain 100 megawatts of power and store 129 megawatt hours, which could power about 30,000 homes according to Tesla. That was more than three times as powerful as the world's next-largest such battery, Mr Musk said on Friday........
?? ..I do not understand why Musk and others, keep saying this..".3 times more powerful than the next biggest"... When Tesla have just installed a 80 MWh battery in California...??

Interesting point.
In the SA offical Tesla battery press conference Elon says that that 80MWh in California claim is an exaggeration. When I watched it live on TV i could have sworn he said some other interesting things but can't find it on any of the videos online, I stored the biggest one I could find in the URL below.
Stretching out the way these specifications are supposed to be used it could be that the 130MWh SA battery is a technical understatement as its claimed to be able to give out 100MW of power thus deliberately engineered for more output in a shorter amount of time. Thus if the battery pack only had to provide 50MW of power then it could claim that the battery pack is technically 260MWh? Or something of that nature, so it could be the idea behind calling it a 130MWh is equally connected with its expected high amount of cycles so it can last 10 years, in theory.
As we all know overly high discharge means considerably less total cycle lifetime.
This chart just can't be posted enough.
I think it might really be like a lot of things that Elon is just stretching the truth to help sell his products. Just like how Elon famously claimed that you can cover a nuclear power-station and its surrounding area with solar panels its performance in general energy output is the same amount of total energy as nuclear, most folks take those statements in quite literal terms so it should be inspected.
I debunked Elon's claim in this thread https://endless-sphere.com/forums/viewtopic.php?f=1&t=54903&hilit=fukushima&start=100#p1208363

at a guess then, since the last reported cost of utility scale Power bank installation was approx US$350,000 /MWh,

....In September, two 210 kWh battery packs cost $145,100 all in, including the cost of an inverter and installation.
..that would put the 129MWh SA installation cost at approx US$17.5 million ..Bargain !
..(Au$23 m)
by my calcs that puts the cost at about US175 per kWh .
All of which makes some of the other projects in the same state very interesting from a cost viewpoint..
.. ie :-- a 400MWh battery (
) from Lyon Group ...Au$200-300 million !!

?? who is screwing who ??
Companies like Zen Energy are just in it for a quicker buck and don't really care about the environment any more than BHP or Chevron do.
These guys like the head of Zen Energy sit in half way in the government and professor heads of universities pushing climate change fear and government lobbying to enrich them selves by having baloney ripoff products to sell via groups like GetUP who also get they cut via donations and favors from these companies.

If had folks in government and Professor heads of major universities had huge personal investments in fossil fuels/uranium they would instantly be dismissed as self-interested jokes, but it's ok if there up to their eyeballs invested in renewable energy companies, and are free to use ABC news and Getup etc to pound their will and thoughts about the world into the Australian public every day.
Looks like Elon nicely snaked them out of their rip off products this time, so good on Elon for that one. I can't help but see Elon's decision to give away this large battery so cheaply was because of the expected free press marketing dividends.
Elon Musks SA battery "investment" should for at least the next 5 years push any news site that puts out articles on how amazing green energy is that the state of South Australia that is 4 times larger than the whole of the UK is now at 50% pure renewables and is healthy and stable all by its self blah blah blah...
He openly says this in the SA Tesla powerpack press meeting that its to demonstrate to the world what Tesla powerpacks can do https://youtu.be/aTXwXlRDGVI?t=12m27s
"Opportunity to make a significant statement to the world about renewable energy"
I think he would have been secretly angry that it came out and even more so if it became common knowledge that at pretty much the exact same time South Australia hit the record for having the most expensive electricity prices in the world. Fortunately for Tesla mainstream media is turned to telling people what they want to hear.
