Abstract: A retrofitted wind turbine installation for replacing a prior wind turbine installation includes the foundation of the prior wind turbine installation and a replacement wind turbine supported by the foundation, wherein the tower of the retrofitted wind turbine installation is a cable-stayed tower to reduce the bending loads imposed on the foundation. A method of retrofitting an existing wind turbine installation with a replacement wind turbine includes disassembling at least a portion of the existing wind turbine, assembling a replacement tower to a remaining portion of the existing wind turbine installation, attaching a plurality of stay cables between the tower of the retrofitted wind turbine installation and stay cable foundations, and attaching the replacement energy generating unit to the replacement tower.

The load carrying structure (3) comprises a first load carrying arrangement (4) and a second load carrying arrangement (4), and each load carrying arrangement (4) comprises a primary structure (9) and at least two secondary structures (10), the secondary structures (10) extending on opposing sides of the primary structure (9) between an energy generating unit (5) carried by the load carrying arrangement (4) and an attachment point at a tower structure (2). Gravity acting on the energy generating units (5) causes push in the primary structures (9) and pull in the secondary structures (10), thereby causing preload of the secondary structures (10). The load carrying structure (3) is capable of handling thrust loads.
