REN Gasodutos, a unit within REN - Redes Energéticas Nacionais, is a Portuguese utilities company headquartered in Lisbon at 55 Avenida Dos Estados Unidos da América, employing between 1,001 and 5,000 people. It operates in two main areas: the transmission of very high voltage electricity with overall technical management of the National Electricity System, and the transport and technical management of the National Gas System, including LNG reception, storage and regasification and underground natural gas storage. The group owns Enondas - Energia das Ondas S.A., a wholly owned subsidiary established to pilot electricity generation from sea waves. REN also operates in telecommunications through RENTELECOM, offering infrastructure, managed services and consultancy. The company follows a conservative international expansion strategy in specialist sectors and stable markets, with Chile identified as a relevant market for its energy sector potential. In 2026 REN announced investments in a green hydrogen hub in the Sines Industrial and Logistics Zone to connect with a broader network for transport, storage and distribution infrastructure.
