System, method, and computer program product for optimally scheduling energy storage devices in wind energy applications. The power production system includes an energy storage device configured to service a first energy storage application at the first wind farm and a supervisory controller configured to determine if an attribute of the energy storage device is less than or equal to a threshold for the first energy storage application. In response to the attribute being less than or equal to a threshold for the first energy storage application, the supervisory controller schedules the energy storage device for a second energy storage application at the first wind farm or at a second wind farm different than the first wind farm. The optimization of the scheduling may be implemented in a computer-implemented method or as a computer program product.
