## 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](https://ampervia.com/rules/spain-rdl-7-2026-data-centers/)), 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.
