A significant power failure affecting Spain and Portugal in April last year prompted industrial companies across both nations to reassess their energy resilience strategies. The outage caused substantial disruptions to manufacturing operations, particularly for businesses dependent on continuous production processes and refrigeration systems. Fribin, a meat processing company in northeastern Spain, experienced hundreds of thousands of euros in losses when production lines halted and perishable inventory was destroyed.
The incident accelerated investment decisions that many companies had delayed due to cost considerations. Fribin subsequently purchased battery storage modules with a combined capacity of 10 megawatt-hours at an investment of approximately €1.5 million, partially funded through European Union recovery programs. Other Portuguese and Spanish manufacturers, including Vista Alegre and Primus Ceramics, similarly expanded or expedited their battery storage installations to protect against future grid disruptions.
Industrial battery deployment across the region has grown substantially. Spain’s battery storage capacity increased from roughly 28 megawatts before the blackout to 193 megawatts by April 2026, according to the national grid operator. Government initiatives have further supported expansion, with Spain’s energy agency allocating €827 million in EU funds to 133 energy storage projects totaling 2,400 megawatts of planned capacity.
Additional weather-related incidents, including a severe storm that disrupted power infrastructure in central Portugal earlier this year, reinforced the necessity for backup systems among businesses and institutions. Battery suppliers report growing demand alongside evolving customer requirements, including instantaneous backup switching capabilities critical for sensitive operations such as hospitals and data centers. Companies also recognize ancillary benefits, including the ability to sell excess stored energy back to electrical networks when market conditions permit.
