Australia could be 100% renewables by 2032 at current rate of wind and solar installs

Renew Economy:

A new study from the Australian National University school of electrical engineering says Australia could reach the equivalent of 100 per cent renewables by 2032, if the current rates of installation of wind and solar continued.

The research, led by Professor Andrew Blakers and Dr Matthew Stock, says the technology and infrastructure needed to support that amount of wind and solar can also be put in place within that time frame.

The most important thing the government of the day can do is to get out of the way, although it will need some considerable facilitation and co-ordination to get everything built and in place in time.

The ANU study says Australia is installing solar PV and wind 4-5 times faster per capita than China, Japan, the EU and the US, and is on track to reach 50 per cent renewable electricity by 2024 – far ahead of Labor’s federal target date of 2030, which the Coalition government describes as “reckless.”

The ANU report says the techniques for balancing and managing a 100 per cent renewables grid are relatively straightforward, and not as expensive as many suggest.

“The cost of hourly balancing of the Australian electricity grid is modest: about $5/MWh for a renewable energy fraction of 50%, rising to $25/MWh for 100% renewables,” it says.

“Thus, the cost of the required storage and transmission is considerably smaller than the cost of the corresponding wind and solar farms. Australia’s coal power stations are old and are becoming less reliable, and transition to a modern renewable energy system can improve grid stability.”
