An elevator system includes an elevator car and a drive unit. The elevator system also includes one or more power sources for providing power to the drive unit, a current sensor and a controller. The controller is configured to cause the current sensor to measure a current through the motor while the elevator car is held stationary at the landing by the motor and/or during an initial phase of the run profile, to determine an available power from the one or more power sources, and to determine a predicted power demand for the drive unit based on the measured current and one or more parameters of the predetermined run profile. The controller is also configured to determine whether the predicted power demand is greater than the available power from the one or more power sources.
