Company Profile


REN - Redes Energéticas Nacionais operates in two major business areas:


  • The transmission in very high voltage electricity and overall technical management of the National Electricity System;
  • The transport of high-pressure natural gas and overall technical management of the National Natural Gas System, guaranteeing the reception, storage and regasification of LNG and underground storage of natural gas.


As a result of the country's commitment to renewable energy, the Portuguese government granted REN the concession to operate a pilot area for generating electricity from sea waves to Enondas - Energia das Ondas. S.A., which is 100% owned by REN.

REN also operates in the telecommunications business via RENTELECOM, which includes a range of services, such as infrastructure, managed services and consultancy.

The internationalisation of REN's operations is a business that is taking its first steps. In February of 2017, REN acquired a 42.5% stake in Electrogas, a Chilean company that owns a pipeline of great relevance in central Chile. On the 1st of October of 2019, REN acquired the entire share capital of Transemel. Predominantly located in northern Chile, Transemel operates 92 km of power transmission lines and five substations, with approximately 93% of its revenue coming from regulated activities.

In order to reinforce its commitment to its operation in Portugal, REN - Redes Energéticas Nacionais acquired REN Portgás, which focuses its activity on the development and exploitation of the natural gas distribution network in the north coast of Portugal. Under a concession agreement with the Portuguese State until 2048, this is the second largest natural gas distribution network in Portugal, with about 4,760 kilometers.

REN meets all the required quality and safety criteria and seeks to be one of the most efficient European energy transmission system operators, while creating value for its shareholders within a framework of sustainable development.
