Weakness Exposed in North European Wind Index System
In northern Europe, a system devised to check individual wind turbine performance against manufacturer guarantees became the basis for predicting the likely energy yield from proposed projects. But as many disappointed investors are discovering, the wind index system was far from robust enough for that purpose.

Gearbox Failures and Design Solutions
As the size of turbines has increased into the multi-MW range, so has the challenge of designing reliable gearboxes able to withstand the huge forces they are subject to, and gearbox failures continue to be a major issue for the wind industry. For example, reports reveal that at one recently constructed offshore wind farm in the UK, retrofits of gearbox bearings on all 30 of the 2MW offshore wind turbines have been required after less than a year and a half of operation, and in another five-year old onshore wind farm, some of the wind turbines are already on their second or third gearbox refit. In this article in Renewable Energy World (March/April 2006), Jan van Egmond of the independent Dutch consultancy, Quality in Wind (which specialises in wind turbine inspection and damage assessment analysis for over 860MW of wind turbines), shares his experiences regarding drive train failures and what lessons can be learned.
