What this means for a data center
No distribution node in Coruña, A publishes 10 MW or more of demand capacity. A data center here would need a transmission-level connection, grid reinforcement or a much smaller load.
Since March 2026, a Spanish demand access permit is tied to the CNAE activity code declared in the request (RDL 7/2026), so the request has to be filed as a data center from the start.
Method
Source: the CNMC’s national access-capacity service, layers Demanda en Distribución and Demanda en Transporte, publication period August 2026, pulled by Ampervia on 2026-10-12. Comparison period: June 2026.
- Distribution: each node’s published available capacity (CAP_DISPONIBLE, MW) for new demand, summed and counted by province.
- Transmission: a Red Eléctrica node is counted as showing demand capacity if any of its published demand categories is above zero.
- Province names are as published by the CNMC. Ampervia does not publish node or municipality detail.
- Published capacity is indicative and changes as permits are granted, lapse or are surrendered. Only the network operator can confirm capacity for a specific request.
