A system may include a top drive coupled to a mast on a drilling rig. Additionally, a common bus may be coupled to the top drive. A drawworks may be coupled to the common bus and the top drive, and the drawworks lowers and raises the top drive throughout the mast. A generator may be coupled to the common bus, and the generator transmits electric power to the drawworks. Further, a controller may be coupled to the top drive, common bus, the generator, and the drawworks. The common bus may transmit the electric power between the top drive, drawworks, and the generator. The controller may manage a transmission of stored power in the top drive to the drawworks.
