Wind turbine timber tower? Yes it’s a reality!!


A wooden wind turbine tower?  Yes you read that correctly – a wind turbine tower made of wood is now a reality and may well be a game-changer for the onshore wind industry. German company TimberTower has erected a 100m prototype wooden tower topped with 1.5MW turbine in Hannover, Germany*.  The tower is constructed of laminated timber panels which are assembled on-site into a hexagonal, octagonal or dodecagonal shaped tower with a cross-sectional diameter in excess of 4.2m which is the maximum possible with conventional steel towers.  Steel turbine towers are limited to a height of approximately 110m by the 4.2m diameter.  The diameter can not be larger than 4.2m as the tower sections would not pass under road-bridges during transportation to the wind farm site.  This restriction does not apply to the timber tower as the component panels fit into standard 40ft containers which are transported on standard trucks.

Thus the advantages of timber towers are twofold:

1. Higher towers will result in more power generation: estimated to be between 30% and 40% more for a tower of 140m which is currently under development

2. Construction cost, including transportation, is estimated to be 20% less than with conventional towers

The question then is:

How to re-value a portfolio of planned on-shore wind projects to take account of the savings made by using timber towers?

Answer:  Enverian Developer makes this easy as this one minute video shows.
