The 50Hz sector power of Itaipu is then transmitted to Ibiúna substation (SP) by a direct-current transmission system with a capacity of 6,300 MW;
- With Uruguay, through the Rivera frequency converting station, with a capacity of 70 MW (Uruguay) and a transmission line in 230 kV, linking it to Livramento substation (Brazil);
- With Argentina, through the Uruguaiana frequency converting station, with a capacity of 50 MW (Brazil) and a transmission line in 132 kV, linking it to Paso de los Libres (Argentina);
- With Venezuela, through a transmission line in 230 kV, with a capacity de 200 MW, interconnecting Boa Vista city, in the State of Rondônia, to Santa Elena city (Venezuela).
