(103-1) Water is an essential natural resource for life. Furthermore, in Celsia, it is a fundamental input to achieve the generation of electrical energy. Our company has 21 hydroelectric plants in Colombia and Panama, which generate more than 70% of our energy. We depend on the availability of this resource for our sustainability.
We have an Environmental Policy that describes our commitment to the efficient use of water and the conservation of hydrographic basins. We apply an integral water-resource-management approach to ongoing projects and new projects in our Organization. Likewise, we promote the generation of energy with alternative sources, such as the sun and the wind, the use of which reduces the pressure on non-renewable natural resources, and we have a thermal backup with resources, such as natural gas and coal.
We obtained a one-year permit to discharge turbine water for the Gualaca and Lorena hydroelectric plants in Panama.
The Zona Franca thermal power plant, in Colombia, exceeded the established goal of reusing 15% of the water collected from the Magdalena River; this is a relevant fact, since until August 2019, in its operation we reached 25%.
(C-GRE-2) The ReverdeC voluntary program for the restoration of hydrographic basins, conservation and increase of forest cover (in Valle del Cauca, Antioquia and Tolima) reached 1.7 million new trees planted in 2019. The accumulated figures between 2016 and 2019 registered more than 4,000,000 trees planted, equivalent to 3,400 hectares. This is how we achieved the annual goal of planting 1,000,000 trees.
The Hydraulic Generation Business has been advancing with the fulfillment of the goal of optimizing 124,000,000 cubic meters (m3) of water by 2021; in 2019, we managed to optimize a total of 89,000,000 m3 of water.
We improved the efficiency of the Unit 1 Francis turbines at the Alto Anchicayá hydroelectric plant, located in Valle del Cauca; we increased its value by 3.1%, which means an estimated saving of 16,000,000 m3 in the use of water for power generation.
Water consumption decreased 28.7% compared to 2018 due to the reduction in thermal generation in Colombia from the sale of the Zona Franca asset in Colombia.
Water Consumption (millions of cubic meters)
Water Catchment (millions of cubic meters)
Total collection of municipal aqueduct
Total catchment from surface sources (lakes, rivers, etc. Does not include sea)
Total catchment from underground sources (does not include brackish water)
Water returned to the extraction source in a quality similar to or superior than what was extracted (turbinated water)
Total water consumption
The total catchment from underground sources for Central America was adjusted for 2017 and 2018, thanks to the fact that we started the registration through meters, beginning in June 2017.
Recycling and Reuse of Water (millions of cubic meters)
Internal Energy Consumption
For Celsia, the management of energy and fuel resources is of great importance from the integral management of corporate strategic risks, which are addressed from the identification of the aspects and impacts in the management instruments, which are monitored and subject to continuous follow-up, and are also aligned with the Company’s policies and strategies.
- Energy consumption in the network of offices in Panama, with the implementation of the on-and-off schedule of the air conditioners according to the working hours of the teams.
- Diesel consumption of 315.74 gallons, compared to 2018, at the Guanacaste Wind Plant (PEG, in Spanish), Costa Rica.
- Gasoline consumption by 133.49 gallons, compared to 2018, at PEG. We did this by optimizing ground-transportation travel.
- Calima: A reduction of 6,233 kWh in electrical energy.
- Alto Anchicayá: A reduction of 10,292 kWh in electrical energy.
- Bajo Anchicayá: A reduction of 7,487 kWh in electrical energy.
- Salvajina: A reduction of 84,737 kWh in electrical energy.

Total Energy Consumption from Non-Renewable Sources Colombia + Central America (A + B + C – E)
Energy consumption from non-renewable sources decreased by 9.6%, compared to 2018. This is because the Zona Franca thermal power plant in Colombia was sold and operated until August. In Central America, there was greater thermal generation, which meant that we did not purchase energy for the auxiliary equipment of the Colón Thermal Power Plant in Panama.
Fuel-supply management includes two key activities for the Company:
The achievement of supply contracts to support the firm energy obligations of the thermal plants.
The process of purchasing fuels to operate the thermal plants, and not only for periods of summer or drought, but also to cover safety generations.
Through fuel management we obtained 100% of the fuel required for the generation of our thermal plants with purchases from different suppliers and we maintained the gas purchase-option (OCG, in Spanish) contracts to support the firm backing of the Energy Obligations from the Meriléctrica Thermal Power Plant in Colombia.
Gas-supply purchases amounted to COP 93.328 billion; we complemented the generation requirements with the efficient purchase of seven cargos of liquefied natural gas (LNG) amounting to 248.4 cubic meters.
Implement the programs for the saving and efficient use of water, aimed at meeting the goals established in Colombia.
Complete the processes for updating the Environmental Management Plans (EMP) for two generation plants in Colombia: Meriléctrica, in Barrancabermeja, and Calima, in Valle del Cauca.
Consolidate the actions approved for the Plan for the Saving and Efficient Use of Water (PUEAA) of the minor plants Amaime, Nima I-II, Río Cali I-II, Riofrío I-II and Calima, in Valle del Cauca, Colombia, related to watershed protection and measures to prevent leaks and water loss.
Start up and begin operations at the small San Andrés de Cuerquia, Colombia, hydroelectric plant with 19.9 MW.
Implement the energy-saving procedure to optimize our energy consumption.
Change the inlet valves of Groups 3 and 4, which will improve reliability and safety in operation and the elimination of leaks for Calima.
Build and put into operation the Rainwater Harvesting and Use System at the Guanacaste wind power plant, in Costa Rica, in order to save drinking-water consumption.
Reuse the consumption of water from the boiler blowdown in the Bahía Las Minas thermal power plant, Panama, in order to reduce the consumption of domestic water in this plant by 30%.
Expand the coverage of automated and monitored buildings in order to monitor at the administrative offices in Yumbo, Colombia.
Implement and continue with the Plan for the Savings and Efficient Use of Water (PUEAA) and with the fulfillment of goals established for the hydroelectric plants in Colombia.
Manage the conservation of water resources through efficient use.
Strengthen the ReverdeC Program until we have planted 16,000,000 trees within the framework of the participatory ecological restoration strategy of this initiative.
Carry out the planting and establishment of 1,800 native trees for the protection of water sources near the Guanacaste wind power plant (Central America) at the rate of 400 trees per year.
Achieve a generation matrix with at least 25% of non-conventional renewable energy sources.
The use of water without consumption of the resource; it is returned to the environment from which it was extracted.
The means or resources that nature offers us and from which, through an industrial process, we obtain some form of energy that can be directly used by the consumer or by some productive activity.
