The invention discloses an energy storage power station which comprises a slope roadbed, a rack rail railway, an electric locomotive, an energy storage load train and an electric power line. The electric locomotive comprises a driving gear, a traction device and a controller, the driving gear is meshed with the rack rail railway; the traction device comprises a pantograph, a switch, a converter and a dual-mode motor; the power line is connected with the dual-mode motor through the pantograph, the switch and the converter; the controller is connected with the switch and the dual-mode motor. The energy storage load train is connected with the electric locomotive; the rack rail railway is laid on the slope roadbed. When the power of the electric power system is excessive, the electric locomotive absorbs electric energy from the electric power system, the dual-mode motor operates in a motor mode to drive the train to move from the slope bottom to the slope top along the rack rail, and the electric energy is converted into gravitational potential energy to be stored. When the power of the electric power system is insufficient, the train slides down along the rack rail from the slope top under the action of gravity, the dual-mode motor operates in a generator mode, gravitational potential energy is converted into electric energy, and the electric energy is transmitted to the electric power system.
