Iberdrola has started to commission three of the four wind farms Cordel-Vidural, Capiechamartín and Panondres in Asturias. The company is working on the construction of the fourth, Verdigueiro, following granting of the administrative authorisation, which will bring the total installed capacity to 130 MW of wind power, thereby tripling its renewable capacity in Asturias. The wind farms consist of SG114 wind turbines, with a unit capacity of 2.62 MW: Cordel-Vidural 37 MW is located between the municipalities of Navia, Valdés and Villayón; Capiechamartín (34 MW) is situated between Tineo and Valdés; and Panondres 21 MW is between Villayón and Valdés. Verdigueiro 36 MW is being built between Tineo and Villayón.
Almost all the field work and civil works have been carried out by Asturias companies such as Hormavasa and Horvalsa, Canteras Rencanos, Deymet, Excade, Posada, Méndez y Mota, Gruas Roxu and Taxus; the project has been developed by ERPASA and the wind turbine tower were manufactured at the Windar facilities in Avilés. These farms entail one of the most complex wind farm infrastructure projects in Spain. The materials (including towers, nacelles and blades) have been transported along narrow, single-track roads with numerous slopes and bends of up to almost 180º. This activity has required exhaustive planning External link, opens in new window. to avoid affecting the planned works and to ensure the arrival of up to 200 daily shipments with different materials. At an altitude of 800 metres, and in an area with constant weather shifts that have made work difficult, large wind turbines have been erected: 56-metre blades, nacelles weighing 126 tonnes and towers between 80 and 93 metres high.
The construction of all these projects, with an investment of EUR 100 million, contributes to boosting the industrial fabric and local employment, involving as many as 1,000 workers.
Once in operation, the wind farms will generate energy to supply more than 100,000 homes and avoid the emission of 65,500 tonnes CO2 per year into the atmosphere.
