Swiss company ABB has won orders worth over $540m from Brazil's Abengoa to deliver technology for a power transmission link to be constructed in Brazil.
The power highway will link two new hydropower plants in the northwest of the country with São Paulo over a distance of 2,500km.
Power will be transmitted at a high voltage (600kV) to minimise transmission losses.
This will be the second transmission project in Brazil using high-voltage direct current (HVDC) at 600kV. The Itaipu project has two transmission lines built by ABB in 1984 and 1987.
ABB will provide two 3,150MW HVDC converter stations, and an 800MW HVDC back-to-back station to transmit power to São Paulo and the alternating current network in the northwest of the country.
The stations are scheduled for completion in 2012 and are part of the government's accelerated development programme.
