Wind Turbines To Have 90m Long Blades. UK's ETI Commissions Project.

The Energy Technologies Institute aka ETI has commissioned a project to develop next generation of large wind turbines with 90 meter long blades. ETI is a UK based company formed from UK government and global companies. ETI is responsible for bringing together projects in the clean energy and infrastructure domain. With the commissioning of new project, the institute will ask developers and designers to build and test the wind turbine blades over 90m long - equal to height of the Big Ben.

Large Wind Turbine Blade

The project is aimed at development of high performance, large offshore wind turbines capable of 8 - 10 MW energy conversion. Typically, the blades are around 40 to 60 meters long. Energy and Climate Change Secretary Chris Huhne believes that groundbreaking innovation is the need of the time so visualize our low Carbon future. He is pleased that ETI is taking initiative to bring together the future designers to develop new technology in the clean-tech. Improving the wind turbine performance will bring down the cost and also make us more capable of clean energy production. Dr David Clarke, ETI Chief Executive that UK is a leader in clean tech with few of the best offshore wind turbines in the world. Generation of clean energy while being very cost effective is a great engineering challenge.

Larger blade size will help in improving the reliability of the wind turbine as well as bring the maintenance costs down significantly. The main challenge in front of designers is to develop & test blades with correct stiffness & aerodynamic design. CE appreciates ETI's lead in this direction and look forward to receiving new design ideas from our CEans.
