Driving efficiency and decreasing the cost of offshore wind energy.

Introducing Haliade-X 12 MW, the most powerful offshore wind turbine in the world.  GE is investing to develop the Haliade-X, the industry’s first 12 MW offshore wind turbine. In addition to being the most powerful wind turbine in the world, the Haliade-X is also the most efficient ocean-based wind platform, with a leading capacity factor of 63%. GE’s investment in the Haliade-X will help make offshore wind a more cost-effective and competitive source of clean energy.

Key features from the Haliade-X 12 MW offshore wind turbine

The Haliade-X offshore turbine features a 12 MW capacity, 220-meter rotor, a 107-meter blade, and digital capabilities.

The Haliade-X 12 MW is not only the most powerful wind turbine in the world but also features a 63% capacity factor—five to seven points above industry standard. Capacity factor compares how much energy was generated against the maximum that could have been produced at continuous full power operation during a specific period of time. Each incremental point in capacity factor represents around $7 million in revenue for our customers over the life of a windfarm.

Power meets efficiency

The combination of a bigger rotor, longer blades and higher capacity factor makes Haliade-X less sensitive to wind speed variations, increasing predictability and the ability to generate more power at low wind speeds. The Haliade-X can capture more Annual Energy Production (AEP) than any other offshore wind turbine even at low wind conditions.

One Haliade-X 12 MW turbine can generate up to 67 GWh of gross annual energy production, providing enough clean energy to power 16,000 European households and save up to 42,000 metric tons of CO2, which is the equivalent of the emissions generated by 9,000 vehicles in one year.
