It also owns 50% of the BBG regasification plant in Bilbao and 72.5% of the Sagunto plant.

Since Enagás came to market in 2002, it has formed part of the Ibex 35 index. It currently has a free float of 95%, one of the highest on the Spanish continuous market.


International activity

Enagás is also present in Latin America (Mexico, Chile and Peru) and Europe (Sweden, Italy, Greece and Albania).

In Mexico, the company holds a stake in the TLA Altamira regasification plant, is a member of the consortium that built and now operates the Morelos gas pipeline and a member of the consortium that developed the Soto La Marina compressor station, in operation now.

Enagás is also involved in the construction of the Trans Adriatic Pipeline (TAP), which will bring gas to Europe from the Caspian Sea linking Greece, Albania and Italy, and holds a stake in Swedegas, the operator of the Swedish gas system. The company is part of the consortium selected for the acquisition of 66% of the Greek gas operator Desfa as well. This transaction is subject to the completion of the further steps envisaged by the tender procedure and by local legislation on privatization.

In addition, Enagás participates in the engineering project of a gas pipeline and a natural gas treatment plant in eastern Morocco.


Projects for descarbonisation

Enagás boosts and develops national and international projects to contribute to the descarbonisation process and to improve air quality. They are initiatives focused on energy efficiency, the use of natural gas in transport, specially maritime transport, or the development of renewable gases (biogas/biomethane, hydrogen, etc), which can be transported by our pipelines network.


Independent TSO

Enagás was certified by the European Commission as an independent Transmission System Operator (TSO) in August 2012. This accreditation guarantees the independence of the Spanish gas transmission network with respect to gas producers and distributors, and represents a milestone in the company's history.


50 years of history

Over the course of its 50-year history, Enagás has developed the key infrastructures for the Spanish gas system, transforming it into a benchmark for security and diversification of supply, and cemented its international presence.
