Colombia: Bi-Lateral Consortium Begins Construction of Ituango Hydroelectric Dam

According to The Latin American Tribune, a consortium on Monday (February 17) began work in diverting the flow of Colombia’s Cauca River, part of the preliminary stage of construction of the Ituango hydroelectric dam, which will be the largest in the Andean nation and the second biggest in Latin America.

The project is funded at $5.5 billion; Brazilian engineer Reinaldo Lino is overseeing the Camargo Correa  component of the effort.

The CCC Ituango consortium is made up of Brazilian construction company Camargo Correa and Colombia’s Conconcreto and Coninsa Ramon H.

The Cauca River begins in Colombia’s southwest and runs 1,350 kilometers (840 miles) north before flowing into the Magdalena, the country’s longest river.

COMMENT: The Cauca will be temporarily diverted between the northwestern towns of Ituango and Briceño, Antioquia province, via two concrete tunnels measuring 14 meters (45 feet) wide by 14 meters tall.

The tunnels will carry the river’s waters a distance of just over 1 kilometer (0.6 kilometers) through the mountains before returning them to their natural course, engineer Julio Zuluaga of the EPM utility, which is managing the overall project.

A 30-meter-high containing wall still must be built to divert the water and create a dry area to construct the dam, which will take four years to build.

“Today, we’re making a commitment to the country to finish the project on time, in December 2018,” EPM CEO Juan Esteban Calle said in a press conference.

The hydro plant will have an installed capacity of 2.4 GW and produce 13,900 gigawatt-hours of electricity per year, sufficient to meet 17% of the nation’s electricity needs at “more competitive rates,” Calle said.
