This accompanying measure concerns the testing of a system to avoid bird collisions with the blades of operating wind turbines. The system consists of a network of cameras, which detect the trajectories of different categories of birds, connected to a sound scaring system, which is activated once a bird enters a risky perimeter around the turbine rotor. Various systems are available on the market and have been operational for a number of years on onshore wind farms. Marine-based versions adapted to offshore sea conditions are currently being developed, however they do not benefit from as much feedback as their onshore counterparts. For this reason, the choice of system has not been fixed in the prefectoral authorization decrees.
