The expansion of renewable energies is one of the central tasks of our time. Hydropower, in particular pumped storage technology, forms the backbone of a stable and sustainable electricity supply. SWIETELSKY is a reliable partner in the realisation of these complex infrastructure projects. With our decades of experience in tunnel, gallery and cavern construction, we are making an essential contribution to the energy transition in Austria and beyond.

We see power plant construction as a holistic task that requires the highest technical precision, geological expertise and perfect project management – especially in challenging alpine terrain.

• Special civil engineering and concrete construction: From complex intake structures in reservoirs to water castles and massive underwater basins – we create the necessary concrete and reinforced concrete structures with the highest precision.
• Logistics in high mountains: We manage personnel, materials and machinery under the most extreme conditions on construction sites at altitudes of over 2,000 metres above sea level.
• Earthworks and rock excavation: We carry out extensive excavation work with a total volume of hundreds of thousands of cubic metres and secure the structures in a sustainable manner.

• Alliance contracts: This model promotes fair risk distribution, transparent communication and optimised, efficient construction. Instead of working against each other, all partners – clients and contractors – pull together.
• Early Contractor Involvement (ECI): We contribute our expertise right from the planning phase. Through this innovative partnering approach, we work with the customer to optimise the project, strengthen the sense of community and lay the foundation for a smooth construction phase.

From the first blast to commissioning – SWIETELSKY stands for reliability, technical brilliance and partnership-based implementation in power plant construction. With a hearty "Glück Auf!" (good luck!), our teams of experts take on every challenge.
