What dantysk sandbank offshore wind gmbh & co. kg does

DanTysk Sandbank Offshore Wind GmbH & Co. KG is a German private limited partnership (GmbH & Co. KG) that operates two adjacent offshore wind farms in the German North Sea — DanTysk (288 MWe, 80 Siemens turbines, 70 sq km, located 70 km west of Sylt) and Sandbank (72 turbines, 60 sq km, 90 km off the Schleswig-Holstein coast). The entity is a joint venture between Sweden-based Vattenfall (51%) and Munich's municipal utility Stadtwerke München (49%). DanTysk was commissioned in December 2014 and Sandbank in 2017, with both assets using monopile foundations in 21–32 m water depths and a rotor diameter of 120 m (tip height 148 m).

The technical architecture centers on conventional offshore wind generation feeding into a Tennet-operated HVDC transmission system: power is collected via 88 inter-array cables totaling 108 km, stepped up to 155 kV AC at the wind farm substation, then converted to DC at the Tennet converter station for a ~200 km loss-minimized transmission to the Büttel landfall in Schleswig-Holstein. A distinctive operational asset is Germany's first offshore accommodation platform — a six-floor facility connected by bridge to the DanTysk substation, housing 50 service technicians, workshops, canteen, gym, cinema, and an onboard hospital, enabling 365-day maintenance across both farms.

The business model is utility-scale power generation sold into the German national grid via Tennet, with revenue mechanics tied to wholesale electricity prices (or EEG-supported tariffs, though not explicitly disclosed). The customer base is effectively the national grid system at the offtake level. Strategic partnerships include Stadtwerke München (equity JV partner), Tennet (grid transmission operator), and Siemens (turbine supplier). Operational synergies are realized through shared infrastructure and common vessels with the Danish Horns Rev wind farm, extending the multi-asset operating model across the North Sea.

Core offering

DanTysk Sandbank Offshore Wind GmbH & Co. KG operates two adjacent offshore wind farms in the German North Sea — DanTysk (288 MWe, 80 Siemens turbines, operational since December 2014) and Sandbank (72 turbines, completed 2017) — generating renewable electricity that is delivered via 155 kV AC connection to a Tennet converter station and transmitted as HVDC over approximately 200 km to Büttel, Schleswig-Holstein. The two farms share Germany's first offshore accommodation platform, housing 50 service technicians and enabling 365-day-per-year maintenance operations.

Product overview

DanTysk Sandbank Offshore Wind GmbH & Co. KG operates two adjacent offshore wind farms in the German North Sea - DanTysk and Sandbank - which together form a significant offshore wind energy portfolio. Both projects are joint ventures between Vattenfall (51%) and Stadtwerke München (49%). The wind farms share operational infrastructure including a unique offshore accommodation platform, which serves as Germany's first offshore hotel for service technicians. DanTysk (288 MWe, 80 turbines) was completed in 2014, while Sandbank (72 turbines) was completed in 2017. The power is transmitted via 155kV connection to Tennet's converter station and converted to DC for 200km transmission to Büttel, Schleswig-Holstein.
