All you need to know about REN

More than 700 people work every day to maintain REN – Redes Energéticas Nacionais as one of the most efficient energy transmission operators worldwide, meeting all the quality and safety criteria necessary to guarantee the uninterrupted supply of electricity and gas to mainland Portugal.  

REN consistently invests in promoting knowledge and research and development, deepening the relationship between academia and the industry, seeking to advance solutions for the major technological and environmental challenges faced at national and international level. An investment that, while creating value for shareholders within a framework of sustainable development, enables participation in the construction of the European energy market and future new-generation transnational infrastructures.  

Portugal is REN’s main focus and natural market, where the company will continue to invest to guarantee long-term electricity and gas infrastructure needs, with a permanent orientation towards greater sustainability, improved performance, and quality of service. The international investment strategy is conservative, focusing on sectors in which the company is a specialist and in markets with economic stability and predictable regulatory frameworks.


Pioneer company in electricity transmission in Portugal 

The history of REN – Redes Energéticas Nacionais began in 1947, when CNE – Companhia Nacional de Eletricidade, S.A.R.L., a pioneering company in the transmission of electricity in Portugal and its original predecessor, was founded. In 1975, with the nationalisations decreed by the Portuguese Government following the revolution on 25 April 1974, it was integrated in Eletricidade de Portugal, S.A. At EDP, REN’s current roles as an electricity transmission company were carried out by the Electricity Network Operational Division. In 2000, this is separated from EDP due to the privatisation of the EDP Group and the liberalisation of the European energy market, which imposed the legal separation between the companies responsible for the management of the transmission network and those that carry out electricity generation and distribution activities. 

In 2003, still under the name Redes Elétricas Nacionais, REN acquired 18.3% of the share capital of Galp Energia, also becoming responsible for the transmission of high-pressure gas. It is then renamed REN – Redes Energéticas Nacionais. 

The company began to be reprivatised in 2007, a process which was completed on 2 February 2012. On 24 April 2014, a decision was made to sell up to 11% of REN by Parpública and Caixa Geral de Depósitos, which culminated in both leaving the company’s reference shareholder structure on 16 June 2014

REN's history begins in 1947 with the founding of the National Electricity Company. Get to know the great milestones of these 75 years until today.
