The 8MW turbine is based on the existing offshore direct drive platform, incorporating only smaller evolutions. The first SWT-8.0-154 will be installed in early 2017, and will allow for up to 10% higher annual energy production (AEP) under offshore wind conditions as compared to the 7MW model.
The upgrade of the offshore direct drive wind turbine to 8MW is made possible through the introduction of new magnet technology with an even higher grade than that introduced in the SWT-7.0-154. This enables a rated power increase of more than 14% from 7.0 to 8.0MW. The turbine will benefit from the established supply chain and components of offshore direct drive technology. These components include the B75 blade and the medium-voltage transformer. Type certification for the 8MW turbine is expected to be obtained at the beginning of 2018.
