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.

The complexity of our work demands even greater innovation and adaptability. We use the most modern tools and methods for static and dynamic investigations of hydraulic systems, mathematical modelling of the foundations and superstructures, static, dynamic and thermal calculations of constructions as well as for transient calculations.

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. As well, 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.
