A wind power plant is provided having a rotor which is rotatably supported with respect to a rotor axis by a bearing arrangement. A rotor blade is fixed to a rotor hub and extends therefrom radially outwardly, with respect to the rotor axis. The bearing arrangement includes a first bearing ring fixed to a support arrangement in a torque-proof manner and disposed coaxially with respect to the rotor axis, and a second bearing ring being rotatably, with respect to the rotor axis, supported on the first bearing ring and fixed to the rotor hub.
