Viesgo has changed a lot since it was founded in Puente Viesgo, Cantabria in 1906. From the initial 25 km of electric power lines, its current network now stretches over 31,000 km, and the original local energy generation has become vast production spread around different parts of Spain and Portugal. However, the enthusiasm of offering an excellent service remains as alive today as it was on the very first day. Discover our history on the timeline.
