OWC Supports Strategic Investment in Baltic Offshore Wind Project Gennaker
Independent Technical Due Diligence (TDD) advising Stadtwerke München in its acquisition of a 25% stake in the 976.5 MW Gennaker Offshore Wind Farm, strengthening investor confidence in one of Germany’s most significant renewable energy assets.
OWC’s technical advisory and due diligence team has supported Stadtwerke München GmbH (SWM) in its acquisition of a 25% stake in the Gennaker, a flagship offshore wind project being developed by Skyborn in the German Baltic Sea.
With a planned capacity of up to 976.5 MW, Gennaker will be the German Baltic Sea’s largest offshore wind farm at the time of construction. Located approximately 15 kilometers north of the Fischland-Darß-Zingst peninsula, the project is expected to generate enough renewable electricity to supply around one million households annually, making it one of the most impactful renewable infrastructure investments in Germany today.

Christian Apeah, Head of Independent Engineering at OWC, emphasises: “High-quality, independent technical due diligence is fundamental to unlocking investor confidence in complex energy infrastructure transactions. Our role is to provide clarity on risks, challenge assumptions, and ensure investment decisions are grounded in robust and bankable fundamentals. We are proud to have supported SWM on this strategic acquisition, helping to strengthen the investment case and underpin a successful transaction in a highly competitive market.”
“This engagement reflects OWC’s strong commitment to the German wind power market,” says Lisa Keaton, Germany Country Manager at OWC. “By combining a strong local presence of our Hamburg-based team with OWC’s global expertise, we provide investors with insight that is both technically rigorous and grounded in the realities of the German offshore wind landscape. I am proud of our team for supporting a German investor in this landmark wind project.”
