EDP Renewables begins the second phase of construction of the first Spanish wind farm to be built with an aerial crane

EDP Renewables has begun construction of the second phase of its Cariondo wind farm in the municipality of Pola de Allanda, Asturias. The innovation lies in the fact that the turbine blades for the wind farm are being carried by aerial cranes, which considerably reduces the environmental impact when compared to the traditional transportation of blades to each turbine’s site, by lorry. Carondio is the first wind farm in Spain and the second in Europe to use this innovative system in its assembly process.

The transfer of the blades is being carried out in two phases – the first was completed in June and the second begins today. The rest of the elements that make up the wind farm, such as towers and nacelles, will be transported using standard land processes. The individual blades are carried directly from Campa de Navia, which is 23 km from the wind farm. The aerial crane, an Erickson S-64 designed for the transportation of very heavy cargo, is piloted by American experts and, with the right weather conditions, can carry 18 blades a day.

The blades are the largest component of a wind turbine and as they cannot be dismantled, transporting them is complex. The blades to be installed at the Carondio Wind Farm are 39m long, are made of fibreglass impregnated with epoxy resin and weigh 6,500 kg. each.

The wind turbines installed in the farm are G80 models supplied by Gamesa, which is also in responsible for the assembly.

The wind farm will have 25 turbines in total and when operational, it will have an installed capacity of 50 MW.

Aided by projects such as this one by EDPR Renewables, Spain is becoming the world’s fourth largest wind power operator. The company has pre-qualified projects totalling 850 MW for 2010, the maximum capacity allowed by the Ministry of Industry this year.
