It now aims to commission its 10MW prototype in the first week of January 2020, having originally targeted first power in autumn 2019.

The manufacturer first announced its 10MW turbine — a successor to its SG 8.0-167 DD model — in January 2019.

The upgrade to a 10MW nameplate capacity was made possible by increasing the generator’s diameter. Rotor diameter has also grown — from 167 to 193 metres.

With its 94-metre blades, the SG 10.0-193 DD has a rotor swept area of 29,300m2 and specific power rating of 342W/m2.

It will also be capable of annual energy production 30% greater than its 8MW predecessor, SGRE claimed.

The manufacturer plans to begin installing a prototype at the test site in Østerild, north Denmark in late November, and — weather pending — produce first power in January 2020, a spokeswoman told Windpower Monthly.

Commercial deployment is slated for 2022. The nacelles will be manufactured at SGRE's facilities in Cuxhaven, Germany.

SGRE has been named preferred supplier for Vattenfall’s subsidy-free Hollandse Kust Zuid I & II and III & IV wind farms in the Dutch North Sea.
