Germany’s Siemens is to supply 300 turbines to the United Kingdom, with each of the turbines totaling 6 MW of capacity. In total, that will come to 1,800 MW of power generation capacity.
The wind turbines used are of the SWT-6.0-154 direct-drive type. Direct-drive means that the blades don’t turn a gear, which would then turn another gear. It utilizes no gears and thus provides the benefit of reliability and mechanical simplicity.
It does, however, come with the consequence of the internal generator being forced to turn at the same low speed that the turbine blades turn at. Offshore wind turbines are often direct-drive because the cost to maintain turbines that are located far offshore is quite high.
“Offshore wind energy has huge potential,” said Michael Suess, a member of the Managing Board at Siemens AG and CEO of the Energy Sector. “Offshore wind conditions are strong and stable enabling an energy yield which can be about 40 percent higher than onshore. The United Kingdom, Denmark and Germany in particular are counting on the future of offshore wind energy. We are pleased that our long-term customer DONG Energy has chosen the latest generation of our wind turbines. Together we are working to further reduce the levelized costs for this environmentally friendly form of power generation.”
Offshore wind farms can generate the greatest and most consistent power supply compared to other wind farms, because offshore winds are stronger and more consistent.
Offshore wind power is more expensive than onshore, but the offshore wind industry is still young and learning.
They will continue to innovate.
