El Cabrito, the oldest wind farm in Cádiz province, has been repowered 24 years after its start-up in 1995 with the aim of improving its technical efficiency and reducing the impact on its surroundings. The main change is the replacement of ninety 330-kW wind turbines of obsolete technology with 12 Nordex-Acciona Windpower machines (8 x 3 MW and 4 x 1.5 MW), maintaining the same total capacity (30 MW) and increasing the output by 16% due to the more efficient wind turbine technology and the highest availability of the turbines.
The project has also meant the removal of 3.4 kilometres of access routes, more than 16,000 m2 of platforms and 31 transformer huts, all of them unnecessary infrastructures in the new wind farm.
Together with improving the surrounding environment, with less visual and noise impact, the passage of migrating birds has been facilitated by increasing the distance between turbines from 45 to 65 metres in a range that varies between 170 m and 300 m, depending on the position. The lower turning speed of the blades also represents a lower risk of collisions.
