Embodiments of the disclosure can relate to bearing health monitoring in power plants. In one embodiment, a computer-implemented method for bearing health monitoring in power plants can include receiving operational data associated with a power plant component. The method may further include receiving training data from one or more power plants. The method may further include determining a signature associated with an anomaly event of the power plant component, based at least in part on the operational data and the training data. The anomaly event of the power plant component may include a wiping of a bearing or a scoring of a bearing. The method can further include generating (1) an alert indicative of the anomaly event or (2) an alert to modify an inspection interval for the power plant component, based at least in part on a comparison of the signature with a threshold signature. The method can further include generating a repair or inspection recommendation for the power plant component, based at least in part on the comparison.
