Teréga, accelerator of the energy transition in the territories

Teréga, accelerator of the energy transition in the territories

For more than 75 years, we have provided territories in the South West with a safe, high-performance gas transport and storage grid. Aware of the role we play in achieving the necessary reduction in greenhouse gas emissions, we are accelerating the energy transition by favouring renewable gases, the circular economy and energy efficiency.

Teréga, a historic actor and driver of change

Located at the crossroads of the main gas flows at the heart of Europe’s energy network, our infrastructures occupy a strategic position. Established in 15 departments across the Far South West, our regional network of more than 5000 km of pipelines and our two underground gas storage sites have a decisive role to play in the energy transition in these territories and the communities within them. We rely on a local flexible grid to support the emergence of local biogas production and to encourage sustainable mobility. . Every day, more than 600 workers are helping imagine and build the new links in the energy system of the future, to serve local communities. Our aim is to be in a position to welcome new decarbonised gases into our grid, such as hydrogen produced using electricity from renewables, or synthetic methane. 

Determined to make gas an accelerator of the energy transition in the territories, we draw on the strengths of collective intelligence and the emergence of innovative solutions.

Gas: accelerator of the energy transition

We feel gas can provide the link between the historic model, largely built on centralised and chiefly fossil-fuelled production, and the model for the future:

  • a smaller carbon footprint thanks to a diversified energy mix,

  • dominated by renewables,

  • and from less geographically dictated sources.

As an actor in that transition, we are positioning ourselves at the heart of the energy system of tomorrow, conceiving innovative solutions backed by the performance, flexibility and adaptability of our gas transport and storage infrastructures.

Toward multi-energy grids

Even now, we are using the most advanced industrial and digital technologies to design multi-energy smart grids: systems within which the different energy sources are connected to one another to optimise usage, particularly by transferring resources lost by some consumers to other consumers that can use them at that precise moment.

That ambition has become a reality through our IMPULSE 2025 project, launched in 2019, which aims to roll out a unique multi-energy grid combining gas, electricity and heat, using a circular economy approach and serving the ecological and energy transition.

The Impulse 2025 project will allow us to demonstrate that it is by optimising existing resources we will meet a large part of the challenges involved in environmental and energy transition.

Teréga: actor in its own energy transition

Because we are dedicated to setting an example, we are committed to an ambitious environmental footprint reduction process. It will be achieved by implementing huge transformations in our infrastructures and our ways of doing business, all part of our BE POSITIF programme.

Finally, we want to ensure the continued excellence of our information system while reducing its cost and environmental impact. Digital frugality is thus central to our digital strategy, optimised to reduce our consumption of resources. Digitising our grid also helps us support our customers in meeting their own greenhouse gas emission and energy frugality targets, offering them an accurate picture of their consumption.
