SN Power and Australian Pacific Hydro are the JV partners developing the project in the Tinguiririca valley upstream of the La Higuera scheme, which they are also building with the same installed capacity and is due to be commissioned late next year. La Confluencia is scheduled to come online in 2010.

Both plants are run-of-river schemes and together they should generate approximately 1400GWh per year of electricity.

The turnkey contract will see the contracting consortium of Hochtief’s local subsidiary and Chilean firm Tecsa engineer, procure and construct (EPC) the project.

SN Power and Australian Pacific Hydro are to build the La Confluencia project for US$350M. Approximately 60% of the project cost will be debt financed.
