More competitive wind turbines

To make wind energy more competitive compared to fossil fuels, Freyssinet devised a new type of prestressed concrete tower to replace conventional steel towers.

Called Eolift, the project, which is currently being developed, consists in building a 120 metre high demonstrator equipped with a 3 MW turbine. An industrialisation innovation complements the structural innovation: to avoid the use of a very large capacity crane, an innovative tower erection and pod assembly tool was designed. Eolift aims to reduce the construction and foundation cost of high-capacity wind turbines by 15%.
