Who are we?

VIESGOAbout ViesgoWho are we?

We are energy

Energy generated by renewable sources such as wind and water, or conventional energy such as coal. Energy that reaches more than 695.000 users in Cantabria, Galicia, Asturias and Castilla y León. The rationale of the electricity company Viesgo is to provide energy, either by generating or distributing it, and with it guide our country towards a better, more efficient and more sustainable future.

At Viesgo, distribution forms the mainstay of our business. The role of the distribution company is to transport energy to homes and businesses via the physical infrastructure. A service that we offer in the north of Spain thanks to an extensive network stretching 31,000 km and that is characterised by its great reliability and quality. This is proven by the continuous improvement of our TIEPI (interruption time equivalent to installed capacity) figures, the unit of reference used to measure the quality of the electricity supply. Despite the dispersion of the network and the complicated orography of the land, the company’s quality of supply has improved year after year to reach a record annual figure of 36.4 minutes in 2017.

Our company focuses on renewable generation, especially wind, which plays a leading role in the global energy transition. Viesgo has 23 wind farms and 2 mini-hydro plants that produce clean and renewable energy throughout the entire Iberian Peninsula, with a total of 505 MW of installed power.

Over 600 highly qualified professionals work in the electricity company Viesgo, along with another 1,500 people who work indirectly in the company, headed by the following management team:
