ABB has successfully commissioned what it claims is the longest transmission link in the world. The 2400 km-long high voltage direct current (HVDC) transmission line will bring electricity from two hydropower plants in the northwest of Brazil to São Paulo, the country’s main economic centre.

ABB delivered two 3150 MW HVDC converter stations to Abengoa for the record-breaking Rio Madeira HVDC project, which will deliver electricity from the Jirau and Santo Antonio hydropower projects.

The company also supplied an 800 MW HVDC back-to-back station that transmits power to the surrounding alternating current (AC) network in the northwest of Brazil

These are the fourth and fifth HVDC transmission links that ABB has delivered in Brazil, succeeding the two Itaipu links (in 1984 and 1987), and the two interconnections between Brazil and Argentina (in 1999 and 2002).
