Thye wind farms – Mallen in Zaragoza, Sierra del Tineo in Asturias, La Victoria in Cadiz and Matabuey in Salamanca – were installed between 2006 and 2011.

The service contract renewal includes the active output management package ‘AOM 5000’ for a period of five years.

AOM 5000 is Vestas’ new service solution optimizing wind power plant output and minimizing customer risk, the company said.

E.ON Climate & Renewables Iberia operations director Manuel Navarro said E.ON has opted for the AOM 5000, as it introduces an energy-based guarantee, which clearly differentiates Vestas service offering from other service providers.

As of May 2010, E.ON Climate and Renewables owns Vestas wind turbines having a total capacity of 700MW in Europe and the US.
