Gas storageSECURLUG - Phase A

2019 - 2024

The Teréga storage centre based in Lussagnet (40) comprises different surface facilities which are used to transport and store the gas in complete safety on our two storage sites of Izaute and Lussagnet. Various technical analyses have shown that some of the facilities should be replaced.

The SECURLUG project therefore involves securing the gas injection and withdrawal flows of our various reservoirs. This project is divided into two phases, A & B.


  • Installation of 2 new electro-compressors, replacing 3 compressors assessed as critical and obsolete.
  • Creation of a new electric building to power the new compressors.
  • Installation of a new decompression vent.
