Improving tower designs for increased hub heights

By Paul Dvorak Size matters with regard to turbine towers, but it is not just as simple as reaching for the sky. There are many more nuances to be considered such as site conditions and wind speed, noise level, safety, and without a doubt the consistent issue of cost. Turbine towers can contribute up to 25% of capital cost, and larger components can be difficult and expensive to transport to site.
A hybrid tower discussed in the report.
Data from 2013 and the Fraunhofer IWES Wind Monitor showed that 33% of all new turbines installed in Europe had hub heights in the range of 120
