Pumped storage stores electricity in the form of potential energy. The basic principle of energy conversion is shown in Fig. 1. In pump mode (charging), electrical energy is taken from the electrical grid to feed a motor that mechanically drives a pump. The water is pumped from the lower basin into the upper basin.
