The technical heart of ewz beats in Sils im Domleschg. It is from here that all hydropower plants, regional and cross-regional electricity grids and wind farms in France are monitored and controlled.
Around 120 specialists work with high precision and responsibility to ensure a reliable and sustainable energy supply for 20 municipalities. Over 250 kilometres of electricity grid, state-of-the-art control technology and in-depth expertise make the Sils site a key pillar of electricity production and distribution in the canton of the Grisons – and beyond.
As a reliable and proactive partner, we ensure a reliable supply of electricity and heat, while also providing planning security. We promote economic stability in the region and are committed to vibrant cooperation. By supporting local associations and cultural events, such as the Bezirksmusikfest, the Open Air Bivio or the Lenzerheide Magic Forest, we help to preserve valuable cultural assets and shape a wide range of leisure activities.
