“Don’t Worry About Intermittency Under 30-40% Renewable Energy Share”


Paul Graham, Chief economist, CSIRO energy, studied the Australian electricity grid

The Australian government’s chief scientific body says there is no apparent technical impediment to reaching 100 per cent renewables for the national electricity grid, and levels of up to 30 per cent renewable energy should be considered as just “trivial” in current energy systems… Graham said the challenges could start to emerge when the penetration of wind and solar move above 40 per cent –as it has in South Australia, which explains why it is focusing on storage and is finally getting traction on its call for changes to energy market rules.

“When we do modelling where we increase the renewable penetration above around 40 per cent of the energy delivered (where South Australia is now) that starts to force out some of that existing dispatchable generation, and then we find that you need to add other technologies to support renewables,’ Graham said.
