About Us
Our Business
EnfraGen Colombia’s power plants are necessary to support the Colombian seasonality of supply due to the country’s hydrologic vulnerability. Our plants are indispensable to the operation and growth of non-conventional renewable power plants, which are intermittent in nature. Typically, our plants operate in cases of drought, emergencies, or transmission system constraints, thus providing critical support to the national electric grid when it is needed most. We are an integral part of the diverse matrix of energy suppliers providing secure and reliable energy to the population and industries in Colombia.
