Authorities in Argentina's Mendoza province have revealed the value of bids offered by three different consortiums vying to construct the Los Blancos I and II hydro plants.
Participants were invited to submit two different offers, with a consortium comprised of companies Texca and Conpern offering estimates of 4.5bn (US$1.09bn) and 4.6bn pesos.
Bids of 5.6bn pesos and 6.2bn pesos were meanwhile submitted by Argentine renewable energy company Impsa in conjunction with subcontracting firms Queiroz Galvão, Impreglio and Triunfio. A separate consortium of construction companies Jose Cartellone Construcciones Civiles and OAS produced estimates of 5.4 and 5.9bn pesos.
The tender contracts on offer cover the construction, operation and maintenance of the two hydro complexes with combined capacity of 485MW. Winners will also construct separate 500kV and 132kV power lines linking the facilities to the national grid.
In a separate statement, Argentina's national power company Enarsa announced that turbine installation at the Rawson I and II wind projects will begin shortly.
Parts of the main turbine body supplied by Danish wind power company Vestas are currently being transported to the project site in the Argentine province of Chubut, Enarsa added in the release.
Total capacity of the turbines will be 77MW, with production slated to hit 320GWh/y. The Rawson I project will have capacity of 50MW, with the remainder of the capacity coming from Rawson II.
