Based on the situation as it stands today, he states that steady growth in new installed capacity can be expected to increase from today's rate of roughly 1,200-1,300 MW per year to 2000 MW annually by the year 2000. New markets are discussed as well as changes in current markets. Long term operating data from wind turbines up and running in various parts of the world offer a valuable source of information. WindStats Newsletter's Danish database provides just such a source of information. David Milborrow took a closer look at data for the 1800 wind turbines of 150 kW and above and came up with some interesting findings about how turbine performance has improved.
Lightning can wreak havoc on wind turbines.
Per fault, lightning causes more loss in wind turbine availability and production per incident that an other faults. Each quarter WindStats publishes tables showing component failures on some of the most popular wind turbines. This quarter, data is included for over 6000 machines. One of the most popular sections of WindStats each quarter is the Turbine Performance Summary table that compares the performance of thousands of wind turbines operating in Denmark and Germany.
