Founded in 1972 and headquartered in Madrid, Enagás, S.A. operates as an independent Transmission System Operator (TSO) certified by the European Union and acts as the Technical Manager of the Spanish Gas System. The company derives the vast majority of its revenue (historically exceeding 90%) from regulated domestic gas infrastructure activities overseen by Spain's National Commission on Markets and Competition (CNMC). Its operations are structured into Regulated Gas Infrastructure, Technical System Operator Activities, Hydrogen Infrastructure, and International / Unregulated activities.
In Spain, Enagás owns and operates an extensive energy infrastructure network comprising around 11,000 km of high-pressure pipelines, three underground storage facilities (Serrablo, Gaviota, and Yela), and primary regasification terminals (including Barcelona, Huelva, Cartagena, and Gijón, alongside stakes in Bilbao's BBG and Sagunto's Saggas). Internationally, Enagás holds strategic equity participations in midstream operators such as the Trans Adriatic Pipeline (TAP), Greece's DESFA, and France's Teréga. As Europe transitions toward decarbonization, Enagás is repositioning its core network to serve as a major European hydrogen hub, developing key Projects of Common Interest (PCI) such as the Spanish Hydrogen Backbone Network and the H2Med corridor.
