Once again a model of price stability

Wind power generation costs stabilised last year after an unprecedented leap in 2005. The cost of gas generation dropped, with the average price once again below that of wind, while coal remained the cheapest option, though on a rising curve. Nuclear's cost is more uncertain than ever. Our annual analysis of power generation costs, which charts wind power's relative economic position, shows that wind plant on good sites with long term power purchase contracts continue to be highly competitive, even though carbon emission permit prices are being kept artificially low.
