Siemens Gamesa Renewable Energy says it will have a prototype of a 14-MW offshore wind turbine that can be uprated to 15 MW ready in 2021 and commercially available in 2024
The SG 14-222 DD direct drive wind turbine will be capable of 15 MW using the company’s Power Boost function. It will have a rotor diameter of 222 m, 108-m blades and a massive swept area of 39,000 m2.
Siemens Gamesa chief executive Markus Tacke said, “Safely and sustainably providing clean energy for our customers and society-at-large is at the core of all we do. The SG 14-222 DD is a product which allows all of us to take giant steps towards protecting and preserving our planet.”
Siemens Gamesa offshore chief executive Andreas Nauen said, “Offshore is in our DNA. The SG 14-222 DD demonstrates our drive to lead the way in a world powered by clean energy. Just one of these turbines will avoid approximately 1.4M tonnes of CO2 emissions compared to coal-fired power generation over the course of its projected 25-year lifetime.”
The turbine’s massive swept area allows the SG 14222 DD to provide an increase of more than 25% in annual energy production compared to the SG 11.0-200 DD offshore wind turbine.
Siemens Gamesa said the new offshore giant also has a low nacelle weight of 500 tonnes, which will enable the company to use an optimised tower and foundation substructure compared to a heavier nacelle. Benefits also arise in the form of lower costs per turbine by minimising materials and reducing transportation needs.
