The Nordex Group has signed an agreement to acquire C1 Connections, a Dutch engineering company specialised in tower connection technology. The transaction brings a core team with specialist structural engineering expertise into the Nordex Group, together with the patented C1 Wedge Connection™ onshore technology and the related IP portfolio and know-how.
SHIFT Invest and Dolfin Capital invested in C1 from 2023 onwards to make the technology ready for use at industrial scale. The acquisition by Nordex, a leading wind turbine manufacturer with extensive turbine and tower engineering expertise and a global customer base, is the natural next step.
Innovative technology from the Netherlands
The C1 Wedge Connection™ technology was developed by the C1 team in close collaboration with Delft University of Technology (TU Delft). The technology was developed as an alternative to bolted connections. Following the installation of an initial prototype, SHIFT Invest and Dolfin Capital invested in C1.
Since the investment, the technology has been brought to commercial readiness and further demonstrated to the wind industry, including through the Wedge Connection Joint Industry Project, made possible by a broad range of leading industry partners.
Global rollout
The acquisition by Nordex will accelerate the adoption of C1’s technology across the onshore wind market. Nordex combines proven turbine and tower expertise with a global customer base and operates a manufacturing network that includes factories in Germany, Spain, Brazil, India, the US and Türkiye.
The offshore wind activities are not part of the transaction perimeter and will be continued in a separate, newly established entity.
