Data center sites in Spain: Madrid, Aragon and more
How Gridscouter ranks Spanish substations for data centers, with backup supply and fiber.
Why here
Cheap solar and wind, plenty of land and large campus announcements by Meta, Microsoft and Amazon have made Spain a fast-growing data center market.
How Gridscouter ranks data center sites
Each substation is scored on voltage, backup supply from a second nearby substation, distance to fiber and existing data centers, and flat industrial land nearby. Every site gets a suggested size in MW.
Where to look
Madrid is the main hub; Aragon and Castilla-La Mancha attract large campuses that need strong 220/400 kV connections.
Note
Gridscouter scores are estimates from open map data, not grid operator capacity figures. Confirm connection capacity with the grid operator.
