Spain grid map: Red Eléctrica's 220 and 400 kV network
Interactive map of high-voltage lines and 1,700+ substations in Spain, from Red Eléctrica's transmission grid to 132 kV distribution.
What the map shows
Lines and substations from OpenStreetMap, colored by voltage. Red Eléctrica runs the 220 and 400 kV transmission grid; utilities such as Endesa and Iberdrola run the 132 kV level.
Connection points
Spain allocates grid access through nodal capacity tenders and published available capacity, so knowing where the substations are is the first step.
Note
Gridscouter scores are estimates from open map data, not grid operator capacity figures. Confirm connection capacity with the grid operator.
