IPA concedes wind farms successful in displacing coal

The anti-wind campaigners sometimes have difficulty getting their facts in the right order. One of their most common complaints is that wind energy does nothing to reduce emissions as it doesnt actually result in any fossil fuel generation being switched off, because fossil fuel needs to keep running as back-up in case the wind stops blowing.
Of course, this is not true. As the Australian Energy Market Operator notes in South Australia, where wind energy accounts for around 25 per cent of both capacity and demand, coal fired generation both local and imported from Victoria has fallen dramatically. There hasnt even been any need for new peaking power stations and the use of gas has not increased since the state started building the first of its 1,200MW of wind energy.
The Institute of Public Affairs, one of the most powerful and influential anti-wind groups, whose former head is now the WA state energy minister, is a strong proponent of the continuous back-up claim. But at the recent, lightly attended anti-wind rally in Canberra, its director of deregulation, Alan Moran made a crucial admission: wind energy is forcing conventional coal generation out of the market, because it is making it uneconomic.
(Renewables) are in fact squeezing out conventional energy, conventional, predictable and reliable energy, because they are must run, and conventional energy is automatically backed off, Moran said, according to a transcript published on the anti-wind website Stop These Things. This is leading to the retirement of coal fired stations, as subsidised wind makes them not profitable.
