The brief

Analyst view
  • Commercial since 2024: 36 of 72 at Denmark's Thor, 107 for Poland Baltica 2, all 66 in Taiwan (Q3 2026 operation).
  • Delivers 30% higher annual output than its 11 MW predecessor using direct-drive generators, reducing maintenance.
  • Prototype validated grid operation in March 2023 at Denmark's Østerild test center before commercial production.

Technical approach

As reported
Rotor design

Large rotor for energy capture

236m rotor and 115m blades capture wind efficiently at scale. The 43,500 m² swept area allows fewer, larger turbines per farm.

Drivetrain

Permanent magnet direct drive

PMG generators couple directly to the rotor with no gearbox, reducing losses and maintenance. Requires precise power electronics for grid syncing.

Blade production

Manufacturing at scale in Denmark

B115 blades manufactured at Aalborg, Denmark facility. Blade fabrication is one of the highest-cost, most labor-intensive turbine parts.

Control

Advanced pitch and yaw systems

Individual blade pitch and yaw optimize power extraction in variable wind and manage loads during gusts and storms.
