ABB wins US80 million contract for Itaipu hydro project substation

ABB has won orders worth about $80 million from Itaipu Binacional, the operator of the Itaipu hydropower plant, to build a new substation in Paraguay and expand an existing installation.

The civil works will be carried out by CIE, a Paraguayan construction company. The order was booked in the second quarter.

The Itaipu Binacional hydro plant is located on the Parana River bordering Brazil and Paraguay. It has an installed capacity of 14,000 MW.

ABB will build a new air-insulated switchgear (AIS) substation rated at 500/220/66 kilovolts (kV) to connect the electricity generated at Itaipu to a new 500 kV transmission line now being built that will help meet increasing demand for electricity in Paraguay. The existing 500 kV 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. Major products to be supplied include 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 100km of optical ground wire - while the line is in service. 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 some 350 kilometers from Itaipu, is expected to be completed in 2013 and will be operated by ANDE (Administracion Nacional de Electricidad), the national power utility of Paraguay.
