> Their electricity prices always have been expensive by Australian standards. However despite the investment of billions replacing coal and gas with wind and solar, those prices have dropped a little. They expect to complete the transition and be 100% renewable this decade.

I think this is one of the drivers for people installing solar on their houses... We have a solar rate of 40% in the state. People want to reduce their powerbill as much as possible, which in turn helps us become more and more 'Green'.

The problem is in summer when the solar input into the grid, vastly outweighs the demand, and the demand spikes with all the airconditioning clicking on in the evening.

Energy Storage (Batteries), plays a huge part in our state becoming self-reliant in a green way.
