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.

  • San Carlos Hydroelectric Power Plant 
    San Carlos Hydroelectric Power Plant

    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.

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

    The reservoir on the Guatapé River comprises an area of 3.4 km2 and has a storage capacity of 62 million m3. The Punchiná Dam is an earthfill gravity dam that is 70 m high and 800 m long.

  • Sogamoso Hydroelectric Power Plant 
    Sogamoso Hydroelectric Power Plant

    With a 190 m high dam and an underground machine room holding the country's three largest generators, the power plant uses water from the Sogamoso River to generate electric energy. With 820 MW this is the fourth largest hydroelectric power plant in Colombia.

    Is located in the department of Santander, in the canyon where the Sogamoso River crosses the La Paz Mountain Range. The project is 75 km upstream from the point where the river empties into the Magdalena River, and 62 km downstream from the confluence of the Suárez and Chicamocha Rivers.

    The Latora Dam and Topocoro Reservoir, being the latter one of the largest in Colombia in terms of extension, covering nearly 7,000 ha, and which holds the largest volume of water, with approximately 4,800 million m3 are located in the jurisdiction of the municipalities of Girón, Betulia, Zapatoca, Los Santos, Lebrija and San Vicente de Chucurí. The municipalities of Barrancabermeja, Puerto Wilches and Sabana de Torres are also in the power plant’s area of influence.

  • Miel I Hydroelectric Power Plant 
    Miel I Hydroelectric Power Plant

    The Power Plant is located in the municipality of Norcasia. It forms part of the hydropower potential found in eastern Caldas, a region comprising the basins of the Guarinó, La Miel, Moro, Manso and Samaná Sur Rivers and minor tributaries such as the Pensilvania and Tenerife Rivers. The Power Plant has an installed capacity of 396 MW across three generation units.

    The plant's Guarinó Diversion Structure has been in operation since 2010. The Manso Diversion Structure began operation in 2013.

    The Patángoras Dam is built over the Miel River. It is a 188 m-high gravity dam made of roller-compacted concrete, forming the 1,220 ha Amaní reservoir, which has a storage capacity of 571 million m3.

  • Termocentro Thermal Power Plant 
    Termocentro Thermal Power Plant

    The Power Plant is located in the Magdalena River’s middle valley, in the district of Puerto Olaya, municipality of Cimitarra (Santander), approximately 5 km from Puerto Berrío (Antioquia). It has an installed capacity of 300 MW.

    It was a gas-fired simple-cycle plant in its first stage, and it began commercial operation with 200 MW, generated by two units (100 MW each). The conversion to a combined-cycle came online with 100 MW from a steam turbine, giving a total of 300 MW.

    The plant has a system to operate using natural gas or liquid fuel.

  • Jaguas Hydroelectric Power Plant 
    Jaguas Hydroelectric Power Plant

    The power station has a total installed capacity of 170 MW through two generation units of 85 MW each. Is located in the department of Antioquia, on the basins of the Nare and Guatapé Rivers, in the jurisdictions of the San Rafael, San Roque, Alejandría, Concepción and Santo Domingo municipalities.

    The Guillermo Cano Dam on the Nare River, one kilometer downstream from the confluence with the San Lorenzo River, consists of an earthfill gravity structure that is 63 m tall, forming a reservoir covering an area of 10.6 km2 with a capacity of 185.5 million ft3.

  • Río Amoyá - La Esperanza Hydroelectric Power Plant 
    Rio Amoyá - La Esperanza Hydroelectric Power Plant

    The Power Plant is located in southern Tolima within the jurisdiction of the municipality of Chaparral, some 150 km from Ibagué. It has an installed capacity of 80 MW across two generation units.

    This power station does not use a water reservoir, but instead uses a run-of-river system that makes use of the water flows of the Amoyá and Davis Rivers. It meets Clean Development Mechanism (CDM) requirements, and thus national and international authorities can be sure of the plant's contribution to climate change mitigation.

  • Calderas Hydroelectric Power Plant 
    Calderas Hydroelectric Power Plant

    The power station has an installed capacity of 26 MW, and uses the water flows of the Calderas and Tafetanes Rivers. The water that flows through the power plant's turbine is ultimately discharged into the San Carlos River that feeds the Punchiná Reservoir, and this increases production at the San Carlos Power Plant.

    It is located in the department of Antioquia, near the highway that connects Medellín to the municipalities of Granada and San Carlos. The powerhouse is located in the basin of the La Arenosa stream, a tributary of the San Carlos River, while the reservoir is located on the high basin of the Calderas River.

    The dam built over the Calderas River is a 25 m-high concrete gravity dam, forming a reservoir that has a storage capacity of 330 thousand m3.

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.
