Hydropower as a renewable source of electricity

Hydropower is the number one renewable energy source and the backbone of Swiss electricity generation. We have been using this energy source for more than 100 years with our own run-of-river, storage and pumped storage power plants in Switzerland and Italy. Hydropower will become even more important in the future: It is carbon-free, efficient and highly flexible.

Energy generation based on an environmentally friendly portfolio

We have an attractive, highly flexible and environmentally friendly hydropower portfolio. Equipped with state-of-the-art technology, our power plants are milestones of Swiss engineering history, which we continuously optimise and control digitally with a high degree of efficiency.

Storage power plants

With our storage power plants, we provide a high degree of flexibility. Find out which power plants we hold a stake in here.

Pumped storage power plants

Highly flexible pumped storage power plants are an essential cog in the wheel for grid stability and security of supply. Find out more about these powerful power plants in which we hold a stake.

Large run-of-river power plants

Here you can find out more about our run-of-river power plants and our contribution toward environmentally friendly electricity generation using river water.

Small-scale hydropower plants

In addition to storage power plants and run-of-river plants, we operate some 30 small-scale hydropower plants in Switzerland and the neighbouring countries. Learn more here.

#prixalpiq

Alpiq has launched the #prixalpiq in collaboration with the Association of Concession-Granting Municipalities of the Canton of Valais. Each year, this prize is awarded to a municipality in Valais in recognition of a project promoting sustainable water management.

Hydropower projects

We make continuous investments in our attractive, flexible and environmentally friendly portfolio of power plants. In this way, we preserve the value of the plants and further increase their production.
