Proven Energy has become aware of a potential manufacturing defect in its Proven 35-2 wind turbine (The Proven 7 and Proven 11 are unaffected). We are investigating this, however, our work to date has now shown that a significant number of shafts may be affected across multiple manufacturing batches. 
With that in mind we are now advising all Proven 35-2 owners to place their wind turbines on brake as soon as it is safe to do so.

Under no circumstances should you apply the parking brake whilst the wind turbine is rotating at normal operating speeds since this will place extra stress on the shaft. We will ensure that you receive regular updates in the interim period. Please accept our apologies for any inconvenience caused.

UPDATE

The Joint Receivers of Proven Energy Limited, Gerard Anthony Friar and Blair Carnegie Nimmo, have announced that Kingspan Renewables Limited acquired the business and assets of Proven Energy Limited on 12 October 2011.  

The management of Kingspan Renewables Limited advise that they will launch 6KW and 3KW turbines, and will manufacture the products in Stewarton, Scotland.  A decision on whether or not to launch a 15KW turbine will be made at a later date, but any launch is unlikely to be before January 2013.
