Grid stability (& instability) is a complex system. All grid operators put a lot of effort into prevdnting cascading shutdowns. And all grid operators have the ability to shut down generators to prevent over generation. No, I don't believe it was caused by renewables.
The anti renewable lobby used to say renewables won't work. Now they are whingeing that renewables make too much electricity.
Hopefully you're wrong.
Dutton has been very unimpressive this election. He has no workable policies and won't release costings.

I have only just noticed that a solar panel site has been created at the edge of my town. It is shielded from sight by the trees on the boundary of the paddock, and the dark colour of the panels camouflages them. I don't know who owns the site, or if it is just there to serve the town.
