We are a global operator of essential infrastructure
Leader in essential services
Electricity
We are a benchmark in the management and operation of high-voltage electricity transmission grids. We manage more than 52,000 circuit kilometres of transmission line in Spain and Latin America. Wherever we are present, we guarantee a secure electricity supply with the highest levels of quality, and we are a driving force behind the transformation of the energy model in order to accelerate the decarbonisation of the electricity system.
Telecommunications
We operate and manage telecommunications networks in Spain and Latin America through our fibre optic assets. Our assets are central to the rollout of 5G networks and, therefore, of a new generation of universal connectivity that will help bridge the current digital divide.
Our companies
Red Eléctrica is Redeia's flagship company. It was founded in 1985 and became the first transmission agent and sole operator of the Spanish electricity system. Since then, it has been serving society, guaranteeing a safe electricity supply of the highest quality to homes, businesses and for public services. Today, it is the backbone of the green transition in Spain and is a key player in driving a sustainable energy model, based on renewable energy and plays a vital role in the fight against climate change. Red Eléctrica manages, maintains and operates more than 45,000 km circuit kilometres of transmission line and more than 600 substations.
Reintel was founded in 1997 and is today the largest dark fibre optic operator in Spain and one of the leading players in the field of telecommunications nationwide. It manages a network of more than 52,000 km of cable deployed over the transmission grid of the electricity system and the railway network. Its main activity is the leasing of dark fibre as well as sites and technical spaces for housing electronic telecommunications equipment. Today, Reintel is the cornerstone for the deployment of 5G networks and, therefore, its role is paramount in providing a new generation of connectivity that is both universal and inclusive.
For more than 20 years, Red Eléctrica Internacional has shared Redeia's knowledge in the energy sector with Latin America, specifically, in the field of electricity transmission. It currently provides essential electricity services in Brazil, Chile and Peru through the management of 7,500 km circuit kilometres of transmission line. Furthermore, Red Eléctrica Internacional is currently an essential agent for the promotion of a sustainable energy model in the region and is the driving force behind Redeia's diversification and growth.
Technological innovation is a cross-cutting value within Redeia, and this is currently channelled through Elewit which was created in 2019 as Redeia's technology platform to develop and promote innovative technological solutions that respond to new challenges in the electricity and telecommunications sectors. Elewit drives a sustainable future through nine key challenges and nine key technologies.
Innovation for 5G: SLISE Project
The SLISE project has been marketed within this context by Redeia and its technology platform, Elewit. It is a cybersecurity initiative whose goal is to reduce any potential weaknesses that the new 5G architectural technologies might provide to the emerging model of communications as a service.
Redeia worldwide
Pioneers from the outset
First TSO in the world
Red Eléctrica was the first TSO in the world (Transmission System Operator): the first company dedicated to the operation and transport of the electrical system. Later, other countries followed suit and today this model is the most widespread in the European Union.
Centre for the Control of Renewable Energies
Established in 2006, CECRE was the first global centre specifically designed for the safe and efficient integration of renewable energy into the electricity system.
Interconnection Spain - Morocco
In 1997 a single electrical interconnection united two continents. Tarifa (Spain) and Fardioua (Morocco) joined through this electrical link that was completed with a second connection that entered service in June 2006.
Link Peninsula - Balearic Islands
The electricity interconnection between the Peninsula and the Balearic Islands is a fundamental project to ensure and improve the reliability of the electricity supply of the Balearic system. It entered service in 2012.
Spain-France underground interconnection
It was put into service in 2015 and connects Spain and France by the east of the Pyrenees. It doubled the exchange capacity with France by increasing the security, stability and quality of the electricity supply of the two countries.
Central Salto de Chira in Gran Canaria
Work begins on the Salto de Chira, the first major energy storage system in the Canary Islands.
