  "textContent": "It is an object to extend the life of a wind power plant while controlling active power output in response to a request from a utility grid. A monitoring and control apparatus (3) applied to a wind-power generation system including a plurality of wind turbine generators includes an estimating section (31) that estimates degradation levels of the wind turbine generators; a grouping section (32) that groups the wind turbine generators on the basis of the degradation levels to form wind turbine generator groups; and an electric-power control unit (33) that controls, upon receiving an active power reduction request from a utility grid side, reduction of the active power of wind turbine generators included in a high-degradation wind turbine generator group, which is a wind turbine generator group including wind turbine generators with a high level of degradation, prior to wind turbine generators included in the other wind turbine generator groups other than the high-degradation wind turbine generator group.",
