Meerwind Süd|Ost

Meerwind Süd|Ost is an 80‑turbine, 288 MW offshore wind farm in the German North Sea located about 23 km north‑west of Helgoland. Delivered by WindMW GmbH, the project is notable as one of Germany’s earliest large commercial offshore farms to be fully financed by private investors and the first German project to close under the KfW offshore financing programme. The development played a pragmatic role in Germany’s early offshore build‑out: sited in moderate depths (c.22–26 m) and designed around an internal transformer platform and a dedicated export link that ties into the HelWin1 HVDC system shared with neighbouring Nordsee Ost. Construction was rapid and largely successful — installation of monopiles, transition pieces, an offshore topside and 80 turbines was completed within an 18‑month campaign, while infield cable installation was finished ahead of some expectations. The project required close coordination between multiple specialist contractors (foundations, heavy‑lift installation, cable laying and topside installation) and certification bodies to manage the engineering and schedule risks of an early large‑scale German offshore installation. Commercially, WindMW (originally backed by Blackstone and Windland) built and operated the farm before a majority stake was sold to Chinese investors (China Three Gorges / China Yangtze Power). Operational output is transmitted via the HelWin1 link to shore. Meerwind is commonly referenced in industry coverage as an early proof point for privately financed German offshore projects and for lessons learned in infield cabling and grid integration.
