International interconnections
We operate four medium and large interconnections with other South American countries:
With Paraguay, through four 500 kV transmission lines, which connect the binational hydroelectric plant of Itaipu to the Margem Direita substation (Paraguay) and the Foz do Iguaçu substation (Brazil). The energy produced by the Paraguayan sector of the plant can be supplied to Brazil, from the Foz substation to the Ibiúna (SP) substation, through a direct current transmission system with a capacity of 6,300 MW;
With Uruguay, through the Rivera frequency converter station (Uruguay), with a capacity of 70 MW, and a 230 kV transmission line, which interconnects the converter to the Livramento substation (Brazil);
With Argentina, through the Uruguaiana frequency converter station (Brazil), with a capacity of 50 MW, and a 132 kV transmission line, which connects the converter to Paso de los Libres (Argentina);
