Hamburg-based turbine manufacturer Nordex Group has signed an agreement to acquire C1 Connections, a Dutch engineering company that has developed a patented system for joining wind turbine tower sections. The deal, announced on 11 November 2026, covers the C1 Wedge Connection™ technology for onshore use, the related intellectual property portfolio and a core team of structural engineers.
Financial terms were not disclosed. C1 Connections’ offshore wind activities are excluded from the transaction and will continue in a separate, newly founded company.
Founded in 2017 and backed by investors Shift Invest and Dolfin Capital, C1 Connections developed the wedge connection as an alternative way of linking tubular tower sections. According to the company, the sections can be manufactured at many locations worldwide, which can help project developers meet local-content requirements.
“C1 Connections brings a differentiating technology and highly specialised expertise that complement our existing capabilities,” said José Luis Blanco, CEO of Nordex Group. Jasper Winkes, founder and CEO of C1 Connections, said the team had spent years preparing the technology for industrial-scale use and would continue developing it within Nordex.
Nordex has installed more than 67 GW of wind capacity in over 40 markets since 1985 and reported group sales of around EUR 7.6 billion in 2025. Its product range focuses on onshore turbines in the 4 to 7 MW+ classes. Tower design and local manufacturing are increasingly relevant in the Baltic onshore markets, where taller towers and local-content expectations shape procurement in Germany, Poland and the Baltic states.
