Spain's Gas Imports Shift to Algeria and Russia as Power Resilience Becomes Critical

In May 2026 Spain’s natural gas imports were led by Russia, which supplied 31,883 GWh (19.5% of total), overtaking Algeria’s 49,657 GWh from pipelines plus 20,685 GWh as LNG, and reducing the United States’ share to 15.2% after a 48% drop in volume. New suppliers such as Senegal (1,118 GWh) and Mexico (999 GWh) entered the market, while former sources like Nigeria, Qatar, Jamaica and Equatorial Guinea ceased deliveries.

A widespread electricity outage in April 2025 that affected Spain and Portugal highlighted the fragility of critical services. Hospitals, highly dependent on uninterrupted power for diagnostics, monitoring and surgical equipment, experienced micro‑cuts and voltage fluctuations that can disrupt sensitive devices within milliseconds. The article stresses the importance of uninterruptible power supplies (UPS), citing solutions like Socomec’s MODULYS GP4 that instantly bridge power gaps to keep critical medical equipment running during transitions to backup sources.
