The basic behavior of such a system is to store the braking energy of trains in a rotating flywheel and to give energy back once it is needed to give traction power to the same or other trains fed by the same catenary. CEDEX work is focused on the design and development of the KESS unit itself, and ADIF is working on analyzing the most appropriate place to install the system from the point of view of optimizing the energy saving, as well as the auxiliary systems needed to install the KESS unit it in a rail substation. 1.- Introduction The electric consumption in rail electric substations is characteris
