The Gournay-sur-Aronde underground natural gas storage site is located 15 kilometres northwest of Compiègne, in the department of Oise, at the junction of seven major pipelines transporting natural gas. Commissioned in 1976, Gournay is the only French storage receiving low calorific gas (B gas) from Groningen (The Netherlands). It is the reason why this site has a strategic place in the gas supply of Picardy and Nord-Pas-de-Calais.
The integration of wells and surface facilities in the landscape has been studied by architects, in order to preserve the site and its environment. A particular attention was paid to the reduction of energy consumption. Thus, the new administrative building, delivered in September 2012, is provide in solar panels and earth-air heat exchangers (EAHE) . This site is also equipped with economizers on the dehydration units to remove liquid waste and improve the quality of the atmospheric emissions.
