This power plant has been in commercial operation for more than 30 years, and it has the largest installed capacity in the country, with 1,240 MW distributed across eight units (155 MW each) and it has the infrastructure necessary for the installation of two additional units. The first stage began operation in 1984 and the second in 1987.

It is located in the department of Antioquia, in the jurisdiction of the San Carlos municipality, near the district of El Jordán.

The electricity generated by the San Carlos Power Plant is delivered to the National Transmission System and then to the Grid's consumption centers through a 230 kV substation.

The power plant is supervised by the National Dispatch Center. It carries out functions relating to automatic generation control, as required.

The reservoir on the Guatapé River comprises an area of 3.4 km2 and has a storage capacity of 72 million m3. The Punchiná Dam is an earthfill gravity dam that is 70 m high and 800 m long.

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.

We prepare the relevant environmental impact assessments and environmental management plans, and we always adhere to the precautionary principle, i.e. if there is any doubt regarding the effect that an action or activity on our part could cause, we do not move forward with it. We carry out this exercise in all our power plants and generation projects' areas of influence, and we implement development programs, understanding each region's characteristics and facilitating participation by the communities.

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.
