With around 60 percent of electricity generated in the country, hydropower plays an important role in Austria's energy supply. The major project that the energy group Verbund is currently implementing in Kaprun also fits in with this. The planned raising of the Limberg dam from 120 to 129 meters will make a significant contribution to increasing the capacity and flexibility of the supply system. Specifically, the storage capacity of the historic reservoir will increase by 12.7 million cubic meters. In future, the reservoir will be able to manage a total of 93.9 million cubic meters of water.
The project will enable more water to be stored in future, particularly in the wet and rainy summer months, which can then be used to generate more electricity in the winter months. The hydropower plant thus not only contributes to the desired energy transition, but also to the prevention of potential power shortages. After all, hardly any other technology is able to store electricity so efficiently on such a large scale and provide it flexibly when needed.
The raising of the dam is part of Limberg 3 power plant project, which itself is part of a large generation group consisting of various reservoirs and power plants. Lombardi was commissioned with the tender and implementation planning for the dam extension. In this challenging project, our engineers were able to benefit from their valuable expertise in the planning and execution of power plant projects. Thanks to valuable experience from comparable construction projects, we dealt intensively with topics such as materials management and concrete technology at an early stage. Both themes had a significant influence on the construction process, the overall costs and the quality of execution.
