All 35 Vestas turbines will use the blades, designed to reduce interference with radar using military technology.

The 96MW Ensemble Eolien Catalan project will be the first, large-scale project to use the technology becoming a demonstration site for the blades. It is being developed by EDF Energies Nouvelles (EDF-EN).

Vestas said the technology would not be offered as standard to the market and is being used on a site-specific basis.

The company also admitted that upgrading radar systems to improve their ability to separate wind turbines from moving objects could be a more cost-effective option.

A consortium, led by BAE Systems Advanced Technology Centre in the UK and including Vestas, has been researching the technology since 2008.

In June, Vestas and EDF-EN signed an 88MW deal to supply 24 V90-3MW and eight V80-2MW turbines to the project with the option to add a further 8MW, which EDF-EN has chosen to do.
