Operating seven power plants in the departments of Antioquia, Tolima, Santander and Caldas, we have a total installed capacity of 3,032 MW distributed as follows: 2,732 MW of hydroelectric power and 300 MW of thermal power. This installed capacity positions our Company as Colombia's third largest generator, consolidating us as a leader in developing the country's energy industry.

We promote hydroelectricity as our main source of energy generation, which relies on the force of water as a renewable, clean, efficient and reliable source that contributes to the sustainable development of regions. We operate two types of hydraulic power stations: based on water stored in reservoirs, or based on run-of-river water flows.

Our environmental management

The environment in which we build our generation projects and operate our power plants comprises three dimensions: biotic (fauna and flora), physical (water, air and soil) and social. Whenever we carry out activities, we consider the relationship between these three dimensions, and commit ourselves to comprehensive environmental management that includes the identification, assessment, prevention, correction, mitigation and offsetting of negative environmental and social impacts, while also seeking to reinforce any positive impacts, thereby complying with current and applicable environmental regulations.

Find out more about our environmental management, the initiatives we carry out with communities from our power plants' areas of influence, and the ENCOMUNIDAD media through which we promote transparent and friendly communication and information.
