ABSTRACT:
Method for the storage and controlled supply of electric energy for discontinuous loads in steelworks and in particular for metal melting systems and rolling mills, the method comprising at least one main supply line (18) connected to a main supply source (11) of electric energy and a plurality of loads (12-13-14-114-20), whereby the level of maximum active power supplied by that main supply source (11) to the steelworks is limited by a sub-station (27) to a level "P.sub.0 " lower than the peaks of maximum absorption by those loads (12-13-14-114-20), the method comprising at least one accumulation line (16) connected in parallel to the main supply line (18) and supplying at least one storage assembly (17), which is connected to the loads (12-13-14-114-20) through a secondary supply line (19).
