Power Grid Map
Spain Power Grid Map
Substations, transmission lines and power plants across Spain on one map, with the connection capacity network operators publish for each substation and the companies behind every project.
Coverage
What the map holds for Spain
Figures from the Tera dataset as of 8 October 2026. The map also shows transmission lines, towers, transformers, switches and compensators by voltage level.
Published connection capacity
The access capacity network operators publish for each substation, shown on the map and in the substation record.
Generation and pipeline
Operating solar, wind, hydro, gas and storage plants, and the large pipeline of projects in development, each linked to its owners and developers.
Transmission and distribution
High voltage lines and substations by voltage level, down to the distribution substations where most solar connects.
Market context
How the grid works in Spain
Red Eléctrica owns and operates Spain's transmission network, while a few large distribution companies, led by i-DE, e-distribución and UFD, run most of the distribution grid. Spain has one of Europe's largest solar and wind fleets and a pipeline of projects many times larger than the grid can connect.
Network operators must publish the access capacity available at their nodes, and capacity at some nodes is allocated through competitive tenders. That makes Spain one of the few markets where developers can screen substations by available capacity before they apply.
