This substation order is for the 14,000MW Itaipu hydroelectric plant located on the Parana river bordering Brazil and Paraguay, and Itaipu Binacional is the operator of the facility.
The civil works for the project will be carried out by CIE, a Paraguayan construction company.
ABB will build a new air-insulated switchgear substation rated at 500/220/66kV to connect the electricity generated at Itaipu to a new 500kV transmission line now being built.
The existing 500kV substation in Itaipu will also be expanded to enable the connection.
ABB will design, engineer, supply, erect, and commission the substations, including the civil works and provide customer training.
The company will supply major products including power transformers, high- and medium-voltage AIS, instrument transformers, surge arresters, cables and auxiliary systems.
The new substation will be equipped with a telecommunications system for the existing 220kV transmission line, including installation of about 100 kms of optical ground wire.
ABB will also install the substation automation systems incorporating the latest protection and control equipment, compliant with the global IEC 61850 open communications standard.
The new Villa Hayes substation, located about 350 kms from Itaipu, is expected to be completed in 2013 and will be operated by Administración Nacional de Electricidad, the national power utility of Paraguay.
