Provided is a method for adapting an operating characteristic of a wind power installation. The installation has a rotor with rotor blades having adjustable blade angles and operable with a variable rotor rotational speed. To control the installation, use is made of an operating characteristic which describes a relationship between the rotor rotational speed and an operating variable. The operating characteristic has a first portion with a first rotational speed range and a second portion with a second rotational speed range. The first rotational speed range has lower rotational speeds than the second rotational speed range, and the operating characteristic is adapted such that values of the operating variable of the first portion are increased values of the variable of the second portion are changed toward higher rotational speeds, and an expected total number of revolutions of the rotor over a predetermined lifetime of the installation remains approximately the same.
