Western Australia, which operates on a separate grid and with a different market system, which means it cannot export surplus power or import when needed, recorded a renewable share of 41.7 per cent for the month.

I’m so used to thinking of WA as a formerly coal and now gas led State, that when i see numbers like this, it does surprise me.

Renewables are creeping inexorably into the energy mix. It was all but guaranteed when their cost became the cheapest a few years back. But its interesting to witness the reality of the phasing energy system.
