Hydro construction

Electric actuation solutions for a sustainable future

 

Hydropower as a reliable, climate-friendly and low-emission energy source plays a key role in energy supply and for the energy transition.

At the same time, increasing costs, stricter environmental regulations and demands for reliable deliveries on the one hand and flexibility on the other hand are rather challenging for the operators of a hydropower plant.

Automation solutions by AUMA have many advantages: They provide the conditions for operating hydropower plants reliably, efficiently and at reasonable cost.

No matter whether you plan to build a new plant or upgrade an existing one: Benefit from decades of AUMA experience with the most varied applications in hydro construction. Let us inspire you with the many advantages of our innovative solutions.
