Grid connections for data centers in Spain
Understanding the power requirements and connection process for data centers in Spain.
High-voltage requirements
Data centers require massive, stable power supplies, often needing direct connections to the 220 kV or 400 kV network.
Strategic locations
Proximity to fiber backbones and existing high-voltage substations is the primary driver for site selection.
Madrid vs Barcelona hubs
While Madrid is the dominant hub, Barcelona and other regions like Aragón are attracting new large-scale data center projects.
Connection requests
Competition for power in industrial zones is high; early engagement with Red Eléctrica is essential for large loads.
