Industrial development of the Tarentaise valley

This project meets the energy needs of the region's manufacturers, the challenges of French reindustrialisation, and securing and developing local employment. It is part of the energy transition, replacing propane and heavy fuel oil and integrating renewable and low-carbon gases.

For the purpose of this project, the company TED (Tarentaise Énergie de Demain) was set up, bringing together manufacturers, local authorities and public-sector players around a common ambition for the future of the valley.

In Savoie, NaTran operates the gas transmission network linking Chambéry to Ugine via Albertville. This network supplies both industrial customers and the public distribution networks operated by GRDF. Apart from La Bâthie, none of the communes in the Tarentaise valley currently has a gas supply service.

The project involves building a new gas transmission pipeline between Albertville and La Léchère, to meet the needs of the Tokai COBEX Savoie and UGI'RING industrial companies as a priority, while opening up economic development prospects for the entire region.

This infrastructure will:

• replace more carbon-intensive energy sources such as heavy fuel oil and propane
• secure the energy supply for these two industrial companies
• integrate renewable and low-carbon gases

Designed from the outset to accommodate natural gas and renewable gases, the future network will eventually be technically compatible with hydrogen.

In addition to the structure, this project strengthens the Tarentaise's industrial resilience, protects jobs and boosts the region's economic appeal.

Mobilised for over five years, the territory’s stakeholders have structured their commitment around the company TED (Tarentaise Energie Demain).

• SAS – Société d’Aménagement de la Savoie
  A public-sector stakeholder in the economic development of the Savoie department, the SAS supports the region's major projects and its industrial transformation.
• Tokai COBEX Savoie
  Operating in La Léchère for over 100 years, Tokai COBEX Savoie employs nearly 400 people and manufactures graphite, historically for the aluminium industry, as well as graphite specialties for chemical and high-temperature applications. More recently, the company has developed graphite grades for use as anodes in Li-ion batteries (electric vehicles, energy storage). Graphite for this application is currently mainly sourced from China, with a high carbon footprint.
  Converting its facilities to gas will reduce emissions of atmospheric pollutants, significantly cut greenhouse gas emissions and reduce road transport of combustibles.
• UGI’RING
  Established in 2022, Ugi’Ring aims to recycle metallurgical waste, nickel oxides, alkaline and saline batteries and catalysts in order to extract critical metals (nickel, molybdenum and manganese) essential for the production of stainless steel.
  This project represents a direct contribution to French and European sovereignty in critical materials, as well as securing supplies for the defence, nuclear, aerospace and healthcare industries. Ugi'Ring enables the transition from a traditional steel industry to a circular, innovative, low-carbon model, in line with the priorities of decarbonisation and reindustrialisation.
