We are building on the energy of tomorrow
Power plant expansion
Behind power plants lie technical and structural masterpieces. We know that every project is unique and requires a customized approach.
Complex and impressive - the power station building
Without power plants, our energy supply in its current form would be inconceivable. At the same time, they are technically extremely complex, which makes their construction challenging. Thanks to their many years of experience, our engineers and specialists can offer you a comprehensive range of services in power plant construction. This is why we are your partner for the construction of large and complex power plants and are happy to provide you with our wide-ranging expertise.
River power plant
Nature has been developing impressive forces for millions of years, which can be used to generate energy with the right technology. Run-of-river power plants convert the flow of rivers into electricity and achieve an outstanding efficiency of almost 94 percent. This is achieved by damming the flowing water, creating a difference in height that can be used to generate electricity.
As simple as this sounds, run-of-river power plants are complex to produce. And yet hydropower is one of the world's most important renewable energy sources that neither consumes raw materials nor emits exhaust gases.
Implenia can look back on a long tradition in the construction of run-of-river power plants. Our experts have already built and renovated numerous large power plants on the Rhine, the Aare and other rivers, thus contributing to the advancement of renewable energy sources. We use different construction methods in our projects in order to be able to react as flexibly as possible to the general conditions and wishes of our customers.
Our range of services
- Concrete and hydraulic engineering
Dam wall
Dams can withstand unimaginable volumes of water and weights. The colossal structures are used as drinking water reservoirs, energy storage facilities, flood protection or for energy generation. Despite their size and robustness, their construction requires surprisingly precise work, not least because physical tricks are used without which the dam could not fulfill its purpose.
We have a particular passion for the often underestimated feat of dam construction, which is why it has become one of our core competencies. Together with our experts in tunnel construction and specialist civil engineering, we build large and challenging dams and retaining structures for you that will effortlessly withstand decades of use. Our flexible construction methods allow us to optimally incorporate the peculiarities of each environment and thus create structures that meet the highest demands.
Our range of services
- Arch walls
- Gravity walls
- Dam wall extension
- Construction of logistics tunnels
