South Australia’s wind energy bonanza
Wind accounts for 58% of energy use in South Australia, By Giles Parkinson on 6 September 2012 It’s been another big week for wind production in South Australia – as another spring weather system with high winds makes wind energy the dominant force in local energy production.
According to figures pulled together by consultants Intelligent Energy Systems using data from the Australian Market Operator, wind energy produced accounted for 57.9 per cent of demand in the state on Tuesday, and followed up with 55 per cent of total demand on Wednesday……
exports from South Australia to other states. On Tuesday, the state was exporting almost all day, as the wind output was quite consistent. On Wednesday, it exported for most of the day and there is a bit of pink at the top in the late afternoon to indicate coal imported from Victoria. (South Australia’s coal generators are in mothballs right now due to the impact of wind, and lower demand, and the carbon price)……
These one day graphs, of course, are just snapshots of an overall trend happening in the state, and across the National Electricity Market, that will only become more apparent as the amount of wind and solar installed in the country increases. Indeed drew Reidy, from IES says these days only rank as the 6th and 12th highest in terms of energy produced on a single day, and 5th and 6th in terms of percentage of demand. The highest day in terms of output was on August 17 this year, while the highest in terms of percentage of demand came in February 5, when wind accounted for 64.1 per cent of demand across the day.
The Clean Energy Council’s Russell March said it was proof that wind energy can generate real power – and lots of it. “This type of significant wind generation is common in South Australia,” he said. In 2011/12, according to AEMO data, wind produced 24 per cent of the state’s generation, overtaking coal. And, Russell noted, AEMO data shows that emissions from South Australia’s electricity sector have dropped every year since 2005/06, and have reduced by more than 27 per cent over the last five years.
“All this wind is putting SA way ahead of the curve on the national Renewable Energy Target, helping provide farmers and local business owners in regional areas with extra income. It also means that the state’s residents collectively have a lower carbon price bill, while getting fully compensated from the Federal Government under the scheme.” Indeed, on Tuesday and Wednesday, the state enjoyed not just by far the cleanest energy in the country, but also the cheapest, with average prices over the day at $43/MWh, compared to more than $52/MWh for NSW….. http://reneweconomy.com.au/2012/wind-accounts-for-58-of-energy-use-in-south-australia-75810
