The San Jose Electric Substation Modernization Project consists of the dismantling of the current infrastructure and the design, construction and commissioning of a new substation and transmission lines, increasing their capacity. The new substation will be encapsulated type GIS, which means that the main equipment will be inside control rooms and will not be visible to the public, thus improving the harmonization of the landscape. The Company’s total investment in the project will be COP $ 20 billion.
The new substation will have two 40-million-volt-ampere (MVA) transformers, totaling 80 MVA, two high-voltage circuits, and support, monitoring, safety and protection equipment and technology imported from various countries. In July 2020, the Company obtained the Environmental License for this project from the District Secretary for the Environment, hence construction works will begin in the second half of the year.
The San Jose Substation will be fully automated and remotely controlled, which will allow the Company's operation to respond better in times of contingency. The automation systems, as well as their power equipment, will be compliant with the highest international standards.

The Environmental Impact Study (EIA) is a basic instrument for decision-making in projects, works or activities that require an Environmental License. It is prepared in order to know the current conditions and the characterization of the area of influence of the project (where it will be carried out), to establish the possible environmental and social impacts that may be generated, and how to adequately manage their prevention, mitigation, correction and/or compensation. With this study, Enel-Codensa’s objective is to always ensure respect for the environment, human health, coexistence and property in nearby areas.
The characterization of the territory in the preparation of the Environmental Impact Study (EIA) of the Modernization Project of the San Jose Electrical Substation and its associated transmission line, was carried out in 2019, using primary and secondary information sources, expressed through the field work and the delivery of information by local, regional and national entities and institutions, such as the Los Martires local Mayor’s office, the District Secretary for the Environment, Ministries, institutes and the inhabitants of the neighborhoods of influence.
According to the characterization of the biotic (flora and fauna), abiotic (soil, water and air) and socioeconomic environment, the Ricaurte, La Pepita, Voto Nacional, La Sabana and La Estanzuela neighborhoods were determined as the area of influence.
The Environmental Management Plan (EMP) comprises the set of measures, actions and activities that Enel-Codensa will carry out during the development of project works, as part of its commitment to the environment and the community. This is the product of the environmental and social evaluation carried out, and its objective is to avoid, prevent, mitigate, correct or compensate for the environmental and social impacts and effects that may be caused by the development of works and the project’s commissioning. These actions are gathered in the following programs:
Abiotic Component Programs: soil, water and air
These programs seek to minimize to the extent possible the effects that the project could have on the soil, water, air and landscape, preventing and controlling the loss of soil, as well as the proper disposal of construction waste, in order to avoid contamination of the nearby soil or water bodies.
Impact Management on soil resource:
- Classification and proper disposal of construction waste in authorized areas, complying with current environmental regulations.
- Build the substation’s drainage works according to designs.
- Cover sewer grates near construction sites.
- Delivery for usage of 100% of recyclable waste.
- Delivery of 100% of hazardous waste (solvent residues, paints, oils) to a manager authorized by the environmental authority.
Impact Management on water resource:
With the purpose of avoiding, mitigating or correcting possible effects on the soil and surface waters, this program aims to implement measures for the adequate management of liquid waste generated in the different phases of the construction and operation of the project.
- Construction of the infrastructure proposed in the designs for the management of oily waste from transformers.
- Temporary storage and proper disposal of all oily waste generated during the construction and operation stages.
Impact Management on air resource:
With the objective of minimizing the impact on the population, this program focuses on enforcing the limits established in the current environmental regulations, supervising the activities for the management and control of particulate material (dust), gas and noise emissions generated by the construction and operation of the Substation.
- Compliance with particulate material (dust) emission levels, with adequate coverage of waste while it is stockpiled, full tenting of dump trucks, speed control of vehicles that transport material, enclosure of work front, mechanical-technical check of vehicles, compliance with preventive maintenance.
