Iberdrola Takes on the Most Complex Wind Farm Construction in Spain

Iberdrola is making progress in Asturias on the most comprehensive wind energy infrastructure project currently underway in Spain: the construction of three of the four wind farms (Cordel-Vidural, Capiechamartín and Panondres) that it has planned for the region, all of which will require an investment of more than €100 million. The company will also start the construction of the fourth project, Verdigueiro, once the administrative authorisations are obtained. This new capacity – 130 MW of wind power – will allow it to triple the installed power it has so far in Asturias.

This week the company commenced the assembly work of the wind turbines, having finished the civil work, planned the arrival of materials at the wind farm sites and organised the different actions to be performed in the field. Up to 400 people are involved in these tasks.

To reach the level of the wind farms, the materials (towers, nacelles and blades, among others) are transported along narrow single-access roads with numerous slopes and bends of up to almost 180º. This activity has required exhaustive planning to avoid effects on the planned works and to make possible 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 make work difficult, large wind turbines are already being erected: blades of 56 metres in length, nacelles weighing 126 tonnes and towers of between 80 and 93 metres in height.

The wind farms will 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 located between Tineo and Valdés; Verdigueiro (36 MW) will be built between Tineo and Villayón and Panondres (21 MW) between Villayón and Valdés.

The construction of these projects is contributing to the revitalisation of the local industrial framework and will make it possible to generate up to 1,000 jobs.

Almost all the field work and civil works are being carried out by Asturian companies such as Hormavasa and Horvalsa, Canteras Rencanos, Deymet, Excade, Posada, Méndez y Mota, Gruas Roxu and Taxus; the project is being developed by ERPASA and the manufacturing of the wind turbine towers, for example, is being carried out at the Windar facilities in Avilés.

In this way, the company is contributing to the consolidation of a model in which Asturian companies and the generation of employment are oriented towards sectors of the future, such as renewable energies.

Once in operation, the wind farms will generate energy to supply more than 100,000 homes and avoid the emission of 65,500 tCO2/year.
