A major development for secure gas supplies and the flexibility of the GRTgaz network

Download the Press Release

GRTgaz has decided to undertake the Eridan project, a major infrastructure that consists in building a new 220 km natural gas pipeline between Saint-Martin-de-Crau (Bouches-du-Rhône) and Saint-Avit (Drôme) for a total of €484 million.

The Energy Regulatory Commission (CRE) just approved this investment in its 19 April 2011 deliberation.

This project will improve operation of GRTgaz’s South zone and will increase interconnection capacities with LNG terminals in Fos-sur-Mer and storage sites in southeast France.
As soon as it is commissioned, it will also help secure the supply flexibility of CCGT plants, which are experiencing sharp growth. Over time, this investment will help to develop connection with  Spain and GRTgaz’s North and South zones to merge.

This project has the European Commission’s support and is one of the infrastructure developments encouraged by the European Union. As such, it is subsidised to the amount of €74 million.

Eridan was the subject of a public debate, which was held from 11 June to 7 November 2009 and which gave rise to 14 public meetings during which territorial players gave their opinions of the project.

Consultations will continue in order to finalise environmental integration studies for the route under consideration, to formally submit a file and obtain the necessary administrative authorisations. This new pipeline is scheduled to be commissioned in 2016.
