Red Eléctrica, Redeia's subsidiary responsible for the transmission and operation of the electricity system in Spain, has in recent days begun the electromechanical assembly phase of the new 220 kV Saguntum substation in Sagunto (Valencia). This is an essential piece of infrastructure for supplying electricity to new industrial developments in the area. Moreover, it will also contribute to boosting the economy of the Valencian Community. 

Due to its importance for the country's reindustrialisation process, the new substation was included in the specific updates to the 2021-2026 Electricity Transmission Grid Plan (MAPs), which were approved last April by the Council of Ministers. The project's permitting and approval process began immediately, thanks to Red Eléctrica's proactive completion of engineering and environmental studies. This demonstrated the company's commitment to accelerating strategic investments for the Valencian Community. 

Once the necessary authorisations were obtained, work began with the earthworks last December 2024. The project has progressed at a good pace and is expected to be commissioned in late 2025. 

This initiative is part of a series of new projects for transport grid infrastructure planned in Sagunto. By providing the necessary power supply, they will enable the significant investments announced by the automotive industry in the town, which are linked to the mobility transition. In total, Red Eléctrica will allocate €62 million to this series of projects. In addition to the 220 kV substation now entering the electromechanical assembly phase, this includes a 400 kV switchyard and the associated lines connecting both facilities to the transmission grid.
