Success of wind and solar energy in South Australia

SA shows wind and solar make energy cleaner and cheaperREneweconomy, By    13 August 2012As Europe has looked towards its biggest and most successful economy Germany to lead the way into green energy, Australians are getting a glimpse into its own grid of the future in the state of South Australia – arguably the advanced economy with the highest wind energy penetration, and now with the highest penetration of rooftop solar PV, in the world.

The latest South Australian Electricity Report (SAER), released by the Australian Energy Market Operator last week, gives some fascinating insights into how wind and now solar PV are changing the nature of the local grid – and providing the state with cleaner, greener and cheaper energy.

For a start, in 2011/12, wind overtook coal as the second biggest producer of energy in the state.

But while solar PV is not included , here’s another interesting set of statistics. South Australia has had the biggest reduction in energy demand compared to forecasts of just a year ago – down 10 per cent from last year’s predictions. Industry demand has fallen, but it still represents growth of 5.4 per cent. The biggest change has been in residential demand, which has fallen 7 per cent. It just so happens that South Australia has the highest penetration of rooftop PV of all the NEM states, meaning – as AEMO states – that ‘”less electricity is being supplied from the grid.”

Indeed, by the end of 2012, two out of five houses in the state had installed rooftop solar PV – more than double the national rate ….. Another interesting snippet from AEMO’s report is that rooftop solar – contrary to some opinion – is helping to meet peak demand….. http://reneweconomy.com.au/2012/sa-shows-wind-and-solar-make-energy-cleaner-and-cheaper-39021
