But in an industry like power generation / "the electric grid," the obviousness of this might be outweighed by momentum (and money?) for the status quo. Especially in regulated services like these (roughly speaking, and depending on the implementation, the industry behaves like a monopoly with more/fewer government-imposed controls), the message and the politics are important to line up, or else a superior technology might only be adopted decades after it's actually viable.

So you might find it to be fluff, but it's good for people to read actual in-the-field success stories.

It's obvious to you and me.

It's not obvious to Joe Voter who wonders why the South Australian government spent millions of dollars on this battery boondoggle by some American millionaire.

The more the message gets out that the battery is working, today, and is already covering for shortfalls / screwups by large scale (non-renewable) generators the better.

So, yeah, fluff piece.

"This is obvious to me and therefore obvious to everyone" isn't the most compelling take on the article.

A refreshing change from the factually incorrect fluff pieces about coal and gas that much of Australia's mainstream media like to publish.
