Siemens announced it has installed the latest version of its offshore direct-drive wind turbine at a test center in Østerild, Denmark.
The SWT-8.0-154 prototype can generate 8 MW with its 154-meter rotor, and was installed on a steel tower with a hub height of 120 meters.
After mechanical and electrical testing, final certification should come in 2018. The prototype already received safety certification from DNV GL earlier this month.
Now, Siemens enters the final development phase for the new turbine, which allows for 10 percent higher annual energy production than the 7 MW model. The higher rating will be achieved with only a few component upgrades, including a new cooling concept and new control systems.
"The installation of the SWT-8.0-154 prototype in Østerild is an important milestone in the success story of our offshore direct drive wind turbines," said Michael Hannibal, CEO Offshore at Siemens Wind Power. "The evolution based on our platform strategy demonstrates that innovation to lower the cost of wind energy can work without compromising the proven reliability of a technically mature product."
Siemens’ line of offshore direct drive turbines was established less than six years ago, but has already produced 100 years of combined operation and 2.5 TWh of electricity. Over 600 Siemens offshore direct drive wind turbines have been delivered to customers.
