An elevator system comprising an elevator car (100) and a drive unit (109) comprising a drive sheave (102) and motor (111) arranged to move the elevator car (101) according to a predetermined run profile. The elevator system (101) also comprises one or more power sources (115; 117) for providing power to the drive unit (109), a current sensor (113) and a controller (123). The controller (123) is configured to cause the current sensor (113) to measure a current through the motor (111) while the elevator car (101) is held stationary at the landing by the motor (111) and/or during an initial phase of the run profile, to determine an available power from the one or more power sources (115; 117), and to determine a predicted power demand for the drive unit (109) based on the measured current and one or more parameters of the predetermined run profile. The controller (123) is also configured to determine whether the predicted power demand is greater than the available power from the one or more power sources (115; 117), and if so, to adjust one or more parameters of the predetermined run profile while the elevator car (101) is held stationary at the landing by the motor (111) and/or during the initial phase.
