Ituango Dam
The Ituango Dam, also referred to as the Pescadero-Ituango Dam or Hidroituango, is an embankment dam currently under construction on the Cauca River near Ituango in Antioquia Department, Colombia. The primary purpose of the project is hydroelectric power generation and its power plant will have an installed capacity of 2,456 megawatts (3,294,000 hp) if completed. Preliminary construction on the dam began in September 2011 and the power plant was expected to begin operations in late 2018, but will not after heavy rainfall and landslides in April/May 2018 blocked the river's diversion tunnel, threatening a breach of the dam. If completed, it will be the largest power station in Colombia.
