Centrais Eletricas Brasileiras (EBR, ELET6.BR), or Eletrobras, Brazil's biggest electric utility, awarded to an Argentine company and a group of three European manufacturers a 5.3 billion Brazilian real ($3 billion) contract to supply parts for the Belo Monte dam, Folha de S. Paulo newspaper reported.

Argentina's Impsa will provide four large turbines for the dam, slated to be the world's third-biggest, Folha said, without saying how it got the information. A group composed of French company Alstom, Austria's Vatech Andritz and German joint venture Voith Siemens will provide the other 14 large turbines as well as six smaller turbines, Folha said.

The selection will be announced officially next week, Folha reported.

The decision to pick those four companies was influenced by the fact that they all have production facilities in Brazil, Folha said. They beat out suppliers from China, Japan and Russia, Folha said, without giving company names.

Impsa told Dow Jones Newswires that it wasn't notified by Brazilian authorities about the decision. Representatives from Eletrobras, Voith, Andritz, and Alstom didn't immediately return calls seeking comment.
