Corporate volunteering

The commitment of Viesgo not only lies with its customers but also with society in general. The best indication of this is the corporate volunteering through which we are committed to social, cultural and sporting initiatives in the area where we undertake our business and for the people who need them most. Because the energy that moves us is not only from the soil, water or wind, but also from the commitment of each and every one of our employees.
