Ecoefficiency
ISA develops and implements tools and environmental management systems that contributes to continuous improvement in the asset's life cycle, promotes sustainable and efficient use of natural resources, controls the impacts and ensure compliance with objectives and performance targets.
Our main individual source of emission corresponds to leaks SF6 gas, which is required in some high-voltage equipment. There are “other emissions” that are individually insignificant (fuels consumption, replacement of refrigerant gases, flights) but together their impact is higher.
The following chart shows the (tonCO2e) average main GHG emission sources from ISA, ISA INTERCOLOMBIA, ISA REP and ISA CTEEP.
Although, energy consumption, water
consumption and waste generation have lower impact in terms on CO2 emissions,
we stablish reduction targets and develop practices to dismiss our
impact on natural resources.
Water consumption
-
Water consumption is given in substations and head offices; it’s obtained from municipal water supply, surface water or groundwater.
-
Despite the intensity of water consumption have low relevance impact on the Energy Transmission Business, we stablished the goal of reducing water consumption by 5% to 2019, based on the average of the last 3 years.
Water consumption (m3)
-
- We highlight the implementation of:
-
- Rainwater catchment
-
- Atmospheric water generators
-
- Dry toilets
-
- Efficient taps
-
- Water collection for air conditioning systems

Energy consumption
-
Energy consumption is given in substations and head offices; it’s associated with renewable and non-renewable energy purchased from the national grid.
-
Despite the intensity of energy consumption have low relevance impact on Energy Transmission Business, we stablished the goal of reducing energy consumption by 5% to 2019, based on the average of the last 3 years.
Energy consumption (MWh)
-
- Energy consumption was so high in CTEEP in comparison with other subsidiaries due to its great infrastructure.
-
We highlight the implementation of:
-
- Campaigns for the well use of the natural resources.
-
- Luminaries replacement by LED technology in substations and administrative offices

Generation of waste
-
It is given in substations and head offices by daily activities and in some cases, it's related with extreme weather events (such as heavy rains or winds) where the amount of waste increases due to the damage to the equipment or fall of vegetation that must be removed and sent to final disposal.
-
Despite the intensity of waste generation have low relevance impact on Energy Transmission Business, we stablished the goal of reducing 5% of solid waste generation as well as 5% of hazardous waste to 2019, based on the average of the last 3 years.
Waste disposed (ton)
-
- Waste generation was so high in INTERCOLOMBIA in comparison with other subsidiaries due to a hydrocarbon spill occurred on a substation, which generated more than 82% of this type of waste.
-
We highlight the implementation of:
- - An agreement with municipalities to increase the percentage of recycled waste.
-
- Campaigns to raise awareness of the importance of sorting waste and making proper use of resources.
-
- Use of waste from maintenance of green areas
-
- The delivery of oils to certified companies, guarantying they got the proper disposal.
