A regenerative integrated actuation system and method are provided to efficiently supply power to a plurality of actuators and to make efficient use of power regenerated by the actuators. The system may include a plurality of actuators in communication with a power distribution system. Each actuator may include an energy storage element. The system may also include a controller for determining if a respective actuator is in a consumption mode or a regenerative mode. If in the consumption mode, the controller may determine whether the respective actuator should draw power from an energy storage element or from the power distribution system. Conversely, if in the regenerative mode, the controller may determine whether any excess power from the respective actuator should be provided to one of the actuators, such as to another actuator which is in the consumption mode or to the energy storage element associated with the respective actuator.
