Five groups submitted offers to Itaipu Binacional for a US$41mn project to supply Paraguay with power from all of the dam's transmission lines.
The bidders were Consorcio ABB-Santa Rita, Elecnor do Brasil, Consorcio Isolux-Concretmix, Toshiba Infraestrutura America do Sul and Alusa Engenharia, the binational operator said in a statement. A decision is expected within 20 days.
Two of Itaipu's four 500kV lines currently supply the landlocked country. Financing will come from the operator's Paraguay retirement and pension entity Cajubi.
Itaipu also announced the Mercosur secretariat granted its no-objection to the result of the bidding process to build the transmission line of the 500kV Itaipu-Villa Hayes transmission project in Paraguay.
In September, Itaipu awarded Consorcio CIE-Elecnor (CIE and Elecnor Transmissão de Energia) the US$166mn contract to build the line, which will take 14 months to complete.
And the operator completed installation of the 242t cover of generation unit 6 as part of a project to repair a crack detected September 2010 during programmed maintenance.
Commercial operations of the unit are penciled in to resume in April, said Itaipu, which boasts 20 units - two of which are normally in reserve - and provides close to 16% of Brazil's demand and 71% of Paraguay's power needs.
