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%.
