German-Spanish wind turbine maker Siemens Gamesa has completed the prototype nacelle for its 10MW offshore model, the SG10,0-193DD, at its factory in Brande, Denmark.

The direct-drive design, first revealed in Recharge in January , is a sizeable step up from the OEM’s 8MW model, with longer 94-metre blades sweeping an area of 29,300 m2 to generate 30% more annual energy production than its forerunner

The prototype of the machine, which Siemens Gamesa CEO Markus Tacke said would “bridge market demand” until the OEM's “true step change”, the as-yet-unnameplated ‘1X’ platform, is in showroom in 2024-25 – will be erected at a test site in Østerild, with trials to “begin shortly”.

The nacelles for the SG10.0-193DD will initially be manufactured at Siemens Gamesa’s factory in Cuxhaven, Germany. Commercial market deployment is slated for 2022.

In April, Vattenfall revealed plans to install a first batch of the 10MW turbines at its Hollandse Kust South 1&2 project in the Dutch North Sea – in line to be the world’s first zero-subsidy offshore wind farm – following the signing of a preferred supplier agreement with the OEM.

Siemens Gamesa main rival, MHI Vestas, also has a 10MW model nearly ready for service, the, and GE Renewable Energy today announced the prototype of it's 12MW Haliade-X had generated its first kWh of power.
