THIS IS THE FUTURE
OF HYDROPOWER

XFLEX HYDRO power plants currently undergoing testing are designed to be more flexible than traditional power plants and provide a range of services to ensure that local and regional power grids remain reliable and resilient to current and future disruptions.

When flexibility means energy security

Grand’Maison hydropower plant has been testing a new operating mode that allows it to generate and store energy at the same time.

Hydro plant upgrades benefit the power grid. And the environment.

The first results of XFLEX HYDRO upgrades have been presented in Switzerland. The technological solutions meet expectations.
