The invention relates to a method for dismantling a wind turbine and erecting a wind energy generating system, wherein the wind turbine comprises a tower placed on a foundation on a wind turbine site and a nacelle with a rotor mounted on the tower. The method comprises the steps of removing the rotor from the wind turbine, mounting an airborne wind energy system for generating electrical power on a part of the remaining wind turbine via a cable, and electrically connecting the airborne wind energy system to a power grid via a power transmission line.

Airborne wind energy system

A blade bearing for mounting a blade of a wind turbine to a hub of the wind turbine comprises inner and outer rings arranged next to each other. One of the inner and outer rings is configured to mount to the blade, and the other is configured to mount to the hub. At least two rows of rolling elements are positioned between the inner and outer rings. Upper and lower rows of the rolling elements are located in respective upper and lower planes. A support structure is secured to the inner ring and extends in a substantially radial direction between the upper and lower planes. The support structure has non-uniform stiffness characteristics in a circumferential direction. A method of manufacturing a blade bearing is also provided.
