The Australian National University School of Electrical Engineering has carried out a new study and that has identified that Australia could be using 100% renewables by 2032. This is particularly true if the current uptake of renewables continues along the same route.
The research and study was led by Professor Andrew Blakers and Dr Matthew Stock who state that it is also possible to put the infrastructure in place by that time in order to support the amount of wind or solar needed to achieve this.
What is significantly important is that the current government moves out of the way because it will take a lot of co-ordination and facilitation in order to achieve that level of infrastructure in the time frame although it is possible.
The study from ANU has found that Australia is installing solar PV and wind at a rate that is 4-5 times faster than that of China, Japan, the EU and the US and so, by 2024, it is looking as thought Australis is going to be on track to reach 50% renewable electricity. This is way ahead of the federal target of 2030.
The ANU report has identified that the techniques required for balancing and managing a 100% renewables grid is fairly simple and does not come at a price that many thought it would. Balancing the Australian electricity on an hourly basis costs around $5/Mwh for a renewable energy fraction of 50% although this will rise to $25/Mwh for 100% renewables.
So, the cost associated with the required amount of storage as well as transmission is a lot lower than the cost that is linked with wind and solar farms. The coal power stations in Australia are now old and are becoming increasingly less reliable and so, moving across to a renewable energy system will only help to improve the stability of the grid.
