Iberdrola has begun commissioning the 63MW Herrera 2 wind complex in Castilla y Leon in Spain.
The complex consists of three farms, La Huesca, Valdesantos and Orbanejoa, totalling 14 wind turbines.
Iberdrola has spent €70m on developing Herrera 2, which has employed around 800 people involved mainly local companies for on-site civil works.
Most components of the wind turbines have been manufactured in Spain, including the multipliers in Burgos, the nacelles in Soria and the turbines in Cantabria.
The SG 4.5-145 wind turbines installed at Herrera 2 have 70 metre-long blades and a diameter of 145 metres. The 4.5MW are the most powerful used at an onshore wind farm in Spain.
The Orbaneja and La Huesa wind farms have been built in the municipalities of Isar, Las Quintanillas, Rabé de las Calzadas and Estepar.
The first of these consists of seven wind turbines, with a total installed capacity of 31.5MW, while the second has four turbines totalling 18MW.
Valdesantos, in Estepar, has three wind turbines with a total installed capacity of 13.5MW.
Over the coming years, Iberdrola plans to develop more than 2.400GW of renewable energy in the Castilla y Leon region, comprising wind and solar, for which it will allocate investments in excess of €2bn.
