Doors open to the public: Discover all the chances to see Enel Green Power’s renewable power plants up close

Into the heart of hydropower generation

In collaboration with the Ente di Gestione delle Aree Protette dell'Ossola (EGAPO - Ossola Protected Areas Management Authority), we’re opening up our hydropower plants in the Ossola Valley, Piedmont, to provide a close-up experience of how hydropower works. Fully qualified guides, including nature experts, will enlighten and educate visitors as they lead them not just around our facilities, but also to other sites of interest located in close proximity to the power plants. An immersive nature experience that’s not to be missed.

Would you like to visit the Entracque power plant? It’s now possible to get a close-up view of Italy's largest hydropower plant, either by visiting the Enel Green Power Information Center, located at the plant, in the municipality of Entracque, or by requesting to go on a guided tour of the power plant. Individuals, schools or groups are welcome to come and discover the secrets of the Gesso Valley dams and how our hydropower plant operates.

Interactive plants

Delve into the heart of energy

The journey begins right away with a suggestion: energy is within each of us. A thermal imaging camera shows people how many Wh (watt-hours) they can generate just with the movement of their bodies. There are plenty of historical aspects and a timeline of technological discoveries, reimagined interactively: the timeline culminates in a wonderful 360-degree video, to understand how all energy sources work.

What gives substance and content to this story-telling project isn’t Enel Green Power, but science. Because renewables are the scientifically recognized answer to decarbonization, and science is what speaks to visitors, using research from the most authoritative sources and a totally agnostic approach. The pros and cons of every choice.

Know, interact, have fun
