Gas networks

Better control

TELLOS Group has long-standing expertise in the design, installation and maintenance of high, medium and low-pressure gas networks. The company possesses the leading-edge engineering skills and top-level knowledge required for tackling any technical challenges, such as the extension of existing networks, the design and construction of gas network structures for public and private services of utilities such as natural gas and propane (under pressure or not).

The gas distribution network offers competitive advantages in terms of energy efficiency and the fight against climate change. Gas networks can rapidly replace more polluting energy sources, such as the coal and fuel used in older heating networks. It also provides the opportunity for developing highly efficient cogeneration systems. The TELLOS Group is consolidating its positioning by adopting an approach which includes renewable energies, such as green gas and biomethane.

Territoires d'avenir: new generation ZAC

Better attractiveness

Territoires d’avenir est la réponse concrète du Groupe TELLOS pour de résoudre l’équation de la transformation économique et de la sobriété foncière, dans le respect des terres et des territoires, en matière d’aménagement des nouvelles zones d’activités. Le Groupe, co-construit avec les élus, des projets qui s’intègrent harmonieusement dans l’environnement, créant ainsi des territoires respectueux et attractifs anticipant et répondant aux besoins de demain à horizon 10 ans.

Territoires d'avenir is a strong commitment to three key pillars: sobriety to enable companies to reduce their carbon footprint sustainably and drastically (decarbonised energy mix, respect for biodiversity, responsible management of resources, rehabilitation of brownfields and retrofitting of existing sites rather than artificialisation of agricultural areas); connections to anticipate the needs of industrialists by giving them the opportunity to take full advantage of the potential of Industry 5. 0 industry (physical connections with multimodal accessibility, very high speed digital connections, data centre or 5G infrastructure); the human aspect in order to create places of life and desire to attract talent (green corridors, cycle paths, health trails and a whole range of attractive services to create an ideal living environment).

Territoires d'avenir is the promise, for the territories and the companies, of a "turnkey" development (as Axioparc, un des 1ers sites industriels TELLOS labellisé par l’État)  grâce à une offre intégrée et structurée, de la conception à la commercialisation.

Better resources

Innovation based on anticipating the future can only be successful when taking the present into account. This is the underlying theme behind TELLOS Group’s environment division, which deals with the rehabilitation of contaminated sites and the management of industrial waste. The Group is based in a region previously dominated by heavy industry, and the rehabilitation of contaminated industrial wasteland was one of the key tasks it was asked to perform in its early days. We now have considerable in-house experience in managing hazardous waste, such as oil refuse.

The Group manages the storage of inert waste from building and public works sites. Whenever possible, the waste is recovered and reused in, for example, road construction and embankments. Our emphasis on using natural or recycled materials underpins our policy of investing in sustainable development and in reducing the wastage and pollution generated by the modernisation of our towns and cities and the maintenance of network infrastructures.

Human resources

Better disclosure

Adapting human resources to both current and future business sectors is of key importance for the TELLOS Group. Vocational training is a crucial lever not just for acquiring and developing employee skillsets but also for their professional development. TELLOS’ training unit has the dual role of training its own employees and also offering a wide range of training programs (including safety, technical, managerial, cross-functional and skill acquisition training) for its subcontractors and clients to boost the employability of all its trainees.

Through its training affiliate, the Group will provide the skills and expert training to support SME human resources and give management the tools they need for resolving employee management and induction issues. The services the Group provides are situated within HR development and can, for example, involve drawing up processes, providing support material, performing audits or organising Team Building training.
