GE’s Haliade-X 12 MW prototype reaches next step in certification process

© GE Renewable Energy

GE Renewable Energy’s Haliade-X 12 MW prototype which is currently operating at the Sif premises in Rotterdam Maasvlakte 2, has received a provisional type certificate from international certification DNV GL.

The certification, IECRE Provisional RNA Component Certificate, demonstrates GE’s Haliade-X prototype has the highest safety and quality standards. It brings the currently largest offshore wind turbine worldwide another step closer to get full type certification.

Type certification is required to demonstrate that new turbines will operate safely, reliably and according to requirements. Testing activities of the 107-meter long blade currently taking place at UK’s Offshore Renewable Energy (ORE) Catapult in Blyth, and at Boston’s Wind Technology Testing Center in the US, will continue as planned to complete all documentation required.

Haliade-X 12 serial production will start at GE’s Saint-Nazaire factory in France during the second half of 2021. According to GE the wind turbine is able to generate up to 67 GWh of gross annual energy production based on wind conditions on a typical German North Sea site. The prototype which has been operational since November 2019 already set a new world record in January 2020 by generating 288 MWh of continuous power in one day.
