An enhanced riser control system may employ electrical tensioners coupled to a drilling riser by wires. The electrical tensioners may provide quick response to a tension controller to handle positioning of the drilling riser. The electrical tensioners of the enhanced riser control system may be combined with hydro-pneumatic tensioners in a riser hybrid tensioning system. A controller within the enhanced riser control system may be configured to distribute tension to electrical tensioners and to control electrical tensioners to adjust the length of the first and second wires. Energy from an electrical tensioner may be transferred to an energy storage system or to power dissipaters for dissipating the energy generated by the electrical tensioner. The energy transferred from an electrical tensioner may be energy that has been generated by the electrical tensioner.
