Beyne's site

The Beynes site is the biggest developed underground storage site in France, with storage in an aquifer located some twenty kilometres west of Versailles. It occupies a strategic place in the procurement of natural gas for Île de France and Normandy.

Commissioned in 1956, the Beynes site is the biggest developed underground storage site in France. The storage is in an aquifer, located some twenty kilometres west of Versailles, and spread across 9 towns in Yvelines.

Between 2007 and 2015, the site underwent major renovation and development works, including the reconstruction of the central station. The aim was to increase security on the site by moving the facilities away from homes, and to reduce atmospheric emissions and noise pollution by incorporating more efficient technologies.
