1. A method for condition-based power plant sensor calibration, comprising: receiving data from one or more power plant sensors; reconciling errors detected within the data from the one or more power plant sensors; calibrating the one or more power plant sensors based at least in part on the errors detected within the data; generating at least one performance model based at least in part on the reconciled data from the one or more power plant sensors; detecting anomalies within the at least one performance model; and tuning the at least one performance model to account for the anomalies.
