Enagás is Spain’s natural gas transmission system operator and Technical System Manager, responsible for planning, building, and operating the high‑pressure gas network and coordinating system balance. Headquartered in Madrid, it runs a regulated infrastructure business that supplies gas to industry, power generators, and distribution companies across the country.
The company owns and operates key gas infrastructures, including major transmission pipelines, underground storage facilities, and LNG regasification terminals in Barcelona, Cartagena, Huelva, and El Musel (Gijón). Its network connects industrial hubs and ports, providing security of supply and flexibility for energy‑intensive sectors, including petrochemical and other process industries.
Through Enagás Renovable, the company develops renewable gases and hydrogen projects, integrating biomethane and green hydrogen into existing networks and advancing hydrogen backbone initiatives and cross‑border corridors such as H2Med. These efforts support the decarbonization of hard‑to‑abate industrial processes and the transition to lower‑carbon feedstocks and energy in the chemical value chain.
