May 19 (Renewables Now) - Siemens Gamesa Renewable Energy SA (BME:SGRE) on Tuesday unveiled a new offshore direct-drive (DD) wind turbine – a 14-MW machine with a 222-metre diameter rotor and blades as long as a football pitch.

The new SG 14-222 DD turbine will be able to reach 15 MW of capacity with the company’s Power Boost function, Siemens Gamesa said.

With 108-metre long blades cast in one piece, the unit will cover a swept area of 39,000 square metres and deliver a 25% increase in annual energy production compared to its 11-MW predecessor.

The nacelle is designed to weigh 500 metric tonnes, which Siemens Gamesa says is light and will allow for optimised tower and foundation installations. This will further lower the cost per unit by minimising sourced materials and reducing transport needs.

According to the company, one SG 14-222 DD turbine will be able to power up around 18,000 average European households per year, while some 30 units can satisfy annual electricity needs of a city the size of Bilbao, Spain.

Siemens Gamesa plans to have the prototype ready in 2021 and make the offshore giant commercially available in 2024.
