What are the motivations behind this article?

The ABC has a mandate to deliver "accurate, impartial, and independent news". It's a government agency and failing deliver that would likely result in serious consequences for anyone who decided not to publish this content.

Articles like this one are a critical component of the way democracy works in this country. Keeping people informed of progress on mitigating climate change is absolutely critical.

What are the interests of the organisations quoted?

That gets a bit more tricky. Nexa is a research organisation that does research into whatever someone pays them to research. They're not unbiased - I don't think they've said who funded them for this paper?

Are NIMBYs the only bottleneck?

Um. No. Obviously not. But they're a big one.

Is it only one place in Victoria that’s affected or are there more?

Again, obviously, there are more.

Are there any technical engineering issues involved?

... yes?

What do you think of the suggestion to switch government incentives from rooftop solar to batteries?

I think the world doesn't have the capacity to produce batteries in the quantities required even if nobody every uses one in a home, so, no. If anything batteries at home should be heavily discouraged. We need those batteries for electric vehicles, not houses.

How quickly could that happen?

Nowhere near quickly enough.
