Operational eco-efficiency

A task in which we are efficient

TGI's commitment to the environment and the communities begins with the optimal use it makes of the necessary resources in the dynamics of gas transportation throughout the national territory.

Why is this important?

(103-1)

Eco-efficiency is important for our organization, understanding that the efficient use of resources leads to less generation of waste and pollution, and at the same time increases the efficiency of the operation. All this contributes to the adaptation of the business to the global environmental sustainability dynamics and, with it, to the economic sustainability of the company.

How do we manage it?

(103-2)

For this purpose, we are aligned with two fundamental elements of TGI's value proposition for the different stakeholders:

Operate and develop the infrastructure of low-emission hydrocarbons with independence and world-class standards in efficiency, reliability, integrity, and sustainability.
Develop innovative solutions that contribute to the energy transition and make operations more efficient.

We ensure the effectiveness of the operational eco-efficiency management with the external audits: ISO 50001 - Energy Management and ISO 14001:15 - Environmental Management System, and with the review made in February and July 2020 at the Sustainable Development Committee.

(103-3) The performance in the management of operational eco-efficiency in TGI is measured with environmental management program indicators that require monthly monitoring of water consumption, energy, generation and disposal of waste by each work center.

What we achieved in 2020

In 2020, TGI obtained the ISO 50001 certification granted by Bvqi Colombia Ltda., in order to make the transition from the standard to the 2018 version.

(GRI 302-1) Energy consumption within the organization

Energy consumption (GJ)	2017	2018	2019	2020
Energy consumption from non-renewable sources (GJ)	997.237,22	1.587.595,16	2.284.557,00	2.324.929,91
ACPM consumption			8.420,00	7.860,62

Consumption of natural gas	997.237,22	1.587.595,16	2.270.983,00	2.315.244,00
Energy purchased from the grid (GJ)	13.371,00	10.081,92	11.223,00	12.041,00
Purchased energy consumption	13.371,00	10.081,92	11.223,00	12.041,00
Total internal energy consumption (GJ)	1.010.608,22	1.597.677,08	2.295.780,00	2.336.970,91

(102-48) Since 2019, the gas consumption data is broken down into two: natural gas and natural gas for vehicles. In 2017 and 2018, this was presented together, as one item.

Our energy consumption increased in 2020 as a result of increases in fuel gas consumption in compression units that operated at higher capacity to expand their energy performance. Furthermore, electricity consumption increased as a result of the start-up of the ECG Sabana, at the beginning of June 2020.

In our search to improve the performance of the use of water in the gas pipeline construction processes, we implemented a resource optimization strategy in the Puente Guillermo La Belleza Loop - Porvenir Miraflores Loop. This consisted in the substitution of water for nitrogen in the hydrostatic pressure tests of the gas pipeline, saving us 52,757 m3 of the resource, corresponding to 80% of the consumption foreseen in the work site.

Challenges for 2021

Measuring the water footprint of tgi and its value chain will be one of the great challenges in 2021, seeking to identify impacts and contributions in the rational use of this resource.

Begin to extend the coverage of the ISO 50001 certification to the entire TGI infrastructure in operation.
Establish goals for the efficient use of water, waste, and energy in all TGI operations.
In the long term, establish water and energy saving devices in all compression stations and operational centers.
