Our history

The Redexis Group has been supplying gas to its users for over 160 years, in a safe, convenient and clean manner. Since its origins, it has tried to provide innovative solutions by implementing advanced gas infrastructures, adapted to each moment in history. 

Natural gas was introduced in Spain in mid 19th Century and was originally used for public lighting, replacing the former liquid petroleum and oil lamps and lanterns. The first gasworks plants were based on the dry distillation of coal, mainly hard coal.

In mid 20th Century, the authorization was obtained for the installation in Zaragoza of the Group’s first compressed gas plant, which was awarded the concession of the city’s lighting through piped coal gas. In this same period, Societé pour l’eclairage des villes de Biarritz et Saragosse acquired the plant and other assets.

The incorporation of Compañía del Gas de Zaragoza, S.A. did not take place until the year 1927, as part of Eléctricas Reunidas de Zaragoza.

In the 70’s, with the arrival of natural gas through the Barcelona pipeline, the company Distribuidora del Gas de Zaragoza, S.A. was incorporated (1976), the maximum shareholder being Eléctricas Reunidas de Zaragoza.

At the beginning of the 80’s, the concession of Gas de Zaragoza, S.A. was transferred to Distribuidora de Gas de Zaragoza, S.A. and the supply of carburized water gas began to be replaced with methane-air.
