That’s what makes this possible.

Part of this funding is to underwrite a new interconnect with the NSW grid, to increase the SA grids ability to transfer power in and out.

Having those interconnects means when we have a surplus or shortage of sun + wind in one location, we can transfer it from somewhere else.

The plan even relies on the ongoing backup of gas turbines, which will be turned off 99.9% of the time, but still require maintenance etc adding cost to the grid.

But the plan is to have enough solar + wind + storage to go 100% net green over any given year.
