Electricity Market Operator charts path to running main Australian electricity grid on 100 percent renewable energy

Renew Economy:

Australia’s Electricity Market Operator has laid out the engineering roadmap it needs to able to operate the country’s main grids on 100 per cent renewable power for “hours and days” at a time.

The good news is that – despite the views of some vocal skeptics – it can be done. But there’s a bunch of things that need to happen first to smooth the way for the power system – for so long dependent on coal and gas – to be capable of running, at times, entirely on renewable energy.

AEMO chief executive Daniel Westerman says operating a gigawatt-scale power system at 100 per cent instantaneous renewable generation is a feat unparalleled in the world.

South Australia has already operated at “net 100 per cent” renewables, but never without any fossil fuel generation. It exports excess wind and solar to Victoria, and in a few years will do so also to NSW through a new transmission link.

By 2025, however, Australia’s entire main grid is expected to reach that landmark event of 100 per cent instantaneous renewables, initially for a half hour period, with nowhere to export to.
