Siemens Gamesa has launched the world’s biggest offshore turbine, the SG 14-222 DD with a capacity of 14MW, a 222 meter rotor diameter, 108 meter long blades, and 39.000 m2 sweeping area.
The 14 MW capacity allows one SG 14-222 DD machine to produce enough energy annually to power around 18.000 average European households. In addition, approximately 30 SG 14-222 DD offshore wind turbines could cover the annual electricity consumption of Bilbao, Spain.
The first prototype will be ready in 2021, while commercially the turbine will be available in 2024.
“We’ve gone bigger for the better. Safely and sustainably providing clean energy for our customers and society-at-large is at the core of all we do. The new SG 14-222 DD is a global product which allows all of us take giant steps towards protecting and preserving our planet. We ourselves became carbon neutral in late 2019 and are on track towards meeting our long-term ambition of net-zero CO2 emissions by 2050. Our installed fleet of over 100 GW both offshore and onshore abates more than 260 million tons of CO2 emissions annually.”Markus Tacke, CEO of Siemens Gamesa Renewable Energy.
“Offshore is in our DNA. Since we helped create the offshore wind industry in 1991, we’ve been determined to safely increase operational performance, minimize technology risks, and create a consistently lower Levelized Cost of Energy. The SG 14-222 DD demonstrates our drive to lead the way in a world powered by clean energy. In fact, just one unit will avoid approx. 1.4 million tons of CO2 emissions compared to coal-fired power generation over the course of its projected 25-year lifetime.”Andreas Nauen, CEO of the Siemens Gamesa Offshore Business Unit.
The rotor has a diameter of 222 meters and uses the latest Siemens B108 blades. Each 108-meter long IntegralBlade is cast in one piece using patented Siemens Gamesa blade technologies.
In addition, the huge 39.000 m2 swept area of the turbine allows the SG 14-222 DD to produce an increase of more than 25 percent in annual energy production compared to the offshore wind turbine SG 11.0-200 DD.
The new offshore giant also features a low weight nacelle at 500 metric tons. This light weight helps Siemens Gamesa to safely use an optimized substructure for the tower and base compared to a heavier nacelle. Therefore, benefits arise in the form of lower costs per turbine by minimizing the amount of sourced materials and reducing transport needs.
The new offshore wind turbine forms the basis of key components such as safety systems, hub and tower concepts, operations and maintenance solutions, along with a strong, qualified supply chain.
