The electrical grid in Andalusia is in a critical state, with 86.5% of its substations lacking available capacity, representing 90% of the national total affected by this phenomenon. This saturation jeopardizes the development of industries, data centers, hotels, and residential complexes in the autonomous community.
According to the latest report from the Industry and Energy Forum (FIE) and Opina 360, out of 6,127 operational substations in Spain, only 826 (13.5%) have access capacity. The system's available capacity has decreased by 282.2 MW, standing at 7,118.6 MW.
Andalusia presents a concerning situation, with only 9.3% of substations having capacity, although it has improved since March. The community now has 879 installations, of which 82 have 941 megawatts free, a significant advance from the previous 630.5 MW.
The province of Málaga is the most affected, with no available capacity since the study began in 2025, having 116 substations without megawatts. It is followed by Córdoba, with only one of its 84 installations operational. Jaén (97.5%), Almería (94.4%), Sevilla (88.8%), and Huelva (87.8%) also report high saturation levels. Cádiz has worsened, moving from 79.2% to 86.2% of substations without capacity. Granada is the best-positioned province, with one in four substations having capacity.
Nationally, the Basque Country leads saturation with 100%, followed by Navarre (99.6%) and La Rioja (98.4%). The regions with the lowest levels are Asturias (41.8%), Balearic Islands (47.8%), and Canary Islands (51.1%). In terms of capacity volume, Galicia leads with 1,409.2 MW, followed by Andalusia (941.8 MW) and Catalonia (832.1 MW).
A measure approved in March by the Government to have Red Eléctrica charge for unused reserved capacity has not yet shown visible effects. Juan Francisco Caro, director of Opina 360, notes that the grid remains saturated and has even worsened in some regions.
The analysis also reveals that, although only 5.6% of substations have technical constraints, these affect 26.8% of the available megawatts. The lack of physical space for expansions is the most common limitation, affecting 234 substations and 530.8 MW.
The study identifies growth potential in 432 substations that could have capacity with reinforcements in distribution networks. The Vice President of the Government, Sara Aagesen, announced a 2030 transport network plan with an investment exceeding 17 billion euros and 193 new substations. Albert Concepción, president of the FIE, considers this measure positive but warns about the timelines, as companies need short-term solutions.
