As part of the overall supply, the company will supply 55, 500kV shunt reactors in Colombia, 28 units in Peru, and 36 in Chile.
ABB Power Products division transformers business head Markus Heimbach said: "ABB’s advanced shunt reactor technology will help even out voltage and load variations, boosting power transmission, enhancing grid reliability and supporting economic development.
"We have a strong presence in South America, and continue to support vital power infrastructure improvements across the region."
The company is planning to deliver the reactors between 2015 and 2017.
