Methods and systems for modeling turbine operation

Methods and systems for modeling turbine operation are disclosed. In one embodiment a method 200 for modeling turbine operation may include: determining 205 current performance parameters 130 of a turbine 105; providing 210 at least one external factor 140 for current or future operation of the turbine 105; and modeling 220, by a predictive model 115, at least one operating characteristic 165 of the turbine 105 based at least in part on the current performance parameters 130 of the turbine 105 and the at least one external factor 140.
