Hydro Power

Our core business

The increasing need for clean energy through the greater use of hydropower is a socio-political necessity today.

Our core business is the planning, design and construction management of hydro-electric power plants, multi-purpose projects and dams, including studies to enhance optimum compatibility with the environment and the fulfilment of increasing safety requirements.

Our experience encompasses a wide range of conventional plants, from the alpine type comprising of long tunnels and hundreds of meters head, to low run-of-river schemes developing a few meters of head, both with weirs and dams. Clients can rely on our expert services in dam design, based on our 100-years' experience, and on our extensive know-how, developed over the more recent past, in the design and implementation of reversible pumped storage plants.

As a result of the rising energy demands, many existing power plants are in need of rehabilitation and upgrading to increase energy efficiency, reliability and flexibility. For a continuous, economical operation of these plants, we provide our clients with complete renewal concepts and investment planning, renovation of penstocks and the optimization of turbines and electro-mechanical equipment.
