Statistical truths

The availability of wind turbines continues to creep closer to the 100% mark, a sure sign of the increasing reliability of the technology. From 1992 to1998, availability in Denmark increased by around 3%. This is just one of the facts revealed in an analysis of wind power output in Denmark, in the current issue of WindStats Newsletter, a Windpower Monthly supplement.

The output of 2839 turbines, two-thirds of Denmark's capacity, is reported. According to the analysis, 488 of the machines have capacities of 100 kW or less, yet though they represent a quarter of turbines in the statistics (26%), they contribute only 5.4% of the energy. Another trend revealed is that the output of 750 kW units is markedly lower than that of 600 kW units, an exception to the rule that productivity increases with machine size. The 750 kW units are generally newer machines, probably installed at less windy sites, since the best sites are already occupied-often by small machines.
