Ralco Hydroelectric Plant

Ralco Hydroelectric Plant is a hydroelectric power station and dam in Bío-Bío Region, Chile. The plant uses water from the upper Bío-Bío River and produces 690 MW of electricity.[1] The plant was built by ENDESA in 2004.[1] The project has proven controversial with local indigenous Mapuche since a graveyard had to be flooded by the dam.
