With the final blade in place, the SG 14-222 DD prototype has become the world’s largest and most powerful turbine to be installed, taking the mantle from GE Haliade-X 14 MW prototype operating in the Port of Rotterdam, the Netherlands.

The SG 14-222 DD turbine model has a 14 MW capacity, reaching up to 15 MW using the company’s Power Boost function. The model features a 222-metre diameter rotor and a 39,000 m2 swept area.

The model is expected to be commercially available in 2024, according to Siemens Gamesa.

The 14 MW capacity allows one SG 14-222 DD machine to provide enough energy to power approximately 18,000 average European households every year. Approximately 30 SG 14-222 DD offshore wind turbines could furthermore cover the annual electricity consumption of Bilbao, Spain, the company said.

The 222-metre diameter rotor uses the new Siemens Gamesa B108 blades. Each 108-metre IntegralBlade® is cast in one piece using patented Siemens Gamesa blade technologies.

Additionally, the turbine’s 39,000 m2 swept area is equivalent to approximately 5.5 standard football pitches. It allows the SG 14-222 DD to provide an increase of more than 25 per cent in Annual Energy Production compared to the SG 11.0-200 DD offshore wind turbine, Siemens Gamesa said.

And Siemens Gamesa is not stopping there. As reported earlier this month, the turbine maker is upgrading this flagship model.
