We turn the element and resource of water into your reliable source of energy.

South Tyrol has been known for generations for genuine craftsmanship and technological pioneering spirit. At sora in Kiens, in the Puster Valley, we combine this tradition with state-of-the-art engineering. We don’t just build hydropower plants – we develop tailor-made solutions that extract the maximum potential from every drop of water.

Whether it’s a new build, modernization, or the revitalization of existing hydropower plants, we support you from the initial turbine design through to turnkey commissioning. Our turbines and control systems are Made in South Tyrol – engineered for maximum efficiency, long service life, and low-maintenance operation.

We deliver tailor-made solutions for every operator profile. Our clients are as diverse as the requirements in hydropower generation. They include private individuals, companies, cooperatives, drinking water and energy utilities, grid operators, and public authorities.

Each hydropower plant is individually engineered to match site-specific parameters such as head, water flow and intended use. The result is not a standard solution, but a unique system – custom-built technology designed for maximum efficiency and operational reliability.

Products and services

Hydropower turbine manufacturing

Geographical conditions and natural site characteristics make every hydropower plant unique. For this reason, we design and manufacture Pelton, Francis, Diagonal and Kaplan turbines exclusively as custom-built units. We are responsible for the mechanical scope of hydropower plant equipment – from engineering and planning through manufacturing to on-site installation. All key process steps are carried out in-house, allowing us to ensure the proven sora quality at every stage. In close cooperation with our electromechanical partners, we deliver complete water-to-wire solutions – fully integrated, from a single source and precisely tailored to the specific site parameters.

Revitalization & modernization of hydropower plants

Hydropower plants are designed for long service lives – typically 30 years or more. Throughout their entire operating life, we provide maintenance and service work for existing plants, regardless of age or manufacturer. As technology continues to evolve, we support plant owners and operators in upgrading their facilities through targeted modernization and revitalization measures. Using our in-house expertise, we improve mechanical components, increase overall efficiency and adapt plants to current technical and regulatory requirementscustom-engineered, reliable and fully aligned with our customers’ needs.

Contract manufacturing

In addition to turbine manufacturing and modernization, we offer comprehensive contract manufacturing services for custom components and assemblies. Our production planning and manufacturing capabilities enable the fabrication of complex parts in a wide range of dimensions. We machine turned components up to Ø 1,300 mm and 2,500 mm in length, mill workpieces up to 8,000 × 3,000 × 1,500 mm, and handle components weighing up to 15,000 kg. Our services are complemented by cylindrical and surface grinding, surface finishing, sandblasting, and in-house assembly. With additional expertise in hydraulics and pneumatics, as well as the development of custom one-off solutions, we support our customers from the initial concept through to the finished component – precise, flexible and reliable.

sora takes its name from company founder Kassian Sora, who realized his first turbine project in Val Badia in 1989, laying the foundation for the company’s future development.

In 2014, the company was acquired by new shareholders – a step that resulted in a significant increase in know-how and a strong phase of growth. Since then, sora has been active not only in South Tyrol but throughout the entire Alpine region as an experienced hydropower plant constructor, firmly established within the industry.

Today, a team of 25 skilled professionals works across engineering, manufacturing and installation, supported by extensive in-house expertise and independent production capabilities. Through close cooperation with en-co, led by Matthias Steindl, we also offer hydropower plant solutions as a full-service provider.
