ReNew Economy has a post on new wind power records being set in South Australia - Graph of the Day: Australia’s big week in wind energy.
Here is the graph for South Australia. It is interesting to note that the 47 per cent that was delivered in August is not the record. The first week in September last year delivered 49 per cent, and there have been numerous peaks above 35 per cent over the last 18 months. In fact, the Australian Energy Market Operator says that wind energy accounted for 27 per cent of demand for the entire 2012/13 fiscal year.
