Red Eléctrica is responsible for the transmission of high voltage power in Spain. To do so, it manages the electricity infrastructures that make up the transmission grid and connects the power generation stations to the points where the power is then distributed to consumers.
Red Eléctrica is the manager of the transmission grid and, as such, acts as the sole transmission agent under a regime of exclusivity as set out in Law 17/2007 of 4 July. In compliance with this Law, in 2010 Red Eléctrica carried out the acquisition of the extra-peninsular assets (Balearic and Canary Islands), as well as those transmission assets on the Spanish peninsula that were pending transfer from electric utility companies. This acquisition represents the definitive consolidation of the model which establishes Red Eléctrica as the sole transmission agent and electricity system operator.
As manager of the transmission grid, Red Eléctrica is responsible for developing and extending the grid, for maintaining it and managing the transmission of electricity between external systems and the peninsula and for guaranteeing third party access to the transmission grid under equal conditions.
Red Eléctrica's transmission grid is composed of more than 41,200 kilometres of high voltage electricity lines and more than 5,000 substation bays, and has more than 78,000 MVA of transformer capacity. These assets make up a secure and reliable meshed grid that offers the highest level of service quality to the electricity system.
