In the north-east of Spain, in Soria, RWE is constructing its 40.8-megawatt Rea Unificado wind farm. The company is erecting nine turbines with a rated output of 4.53 megawatts each, by far the largest and most powerful in its Spanish fleet. After commissioning, Rea Unificado will be able to supply 30,000 Spanish households with green electricity.In its 17th Spanish onshore project, RWE has used 'Soft-Spot foundations' for the first time. Reinforced concrete spread foundations are used and placed on an EPS layer, an insulating material made of expanded polystyrene. Instead of transferring the loads to the subsoil, the EPS redistributes them to a donut-shaped surface. This increases stability and reduces the diameter of the foundation slabs and volume of the concrete used.The Rea Unificado wind farm is scheduled to be fully operational by the end of the year. Furthermore, RWE is currently constructing two Spanish solar parks with a total capacity of 88 megawatts.
