Spain will soon require mobile carriers to maintain network connectivity during power outages through backup systems. A royal decree expected by late 2026 mandates that operators serving over 500,000 users or earning more than €50 million annually must keep services running for at least four hours when electricity fails. The rule targets roughly 100 operators across the country.

Coverage requirements ramp up over three years: half the population must be protected within the first year, 65 percent in year two, and 75 percent by year three. Critical infrastructure faces stricter standards—control centers that could disrupt nationwide service must remain operational for 24 hours post-outage, while emergency call centers need contingency plans. These measures respond directly to a massive 2024 blackout that left Spain, Portugal, and parts of France dark for hours.

The regulation acknowledges evolving technology, noting that satellite-based direct-to-phone connectivity could eventually make terrestrial backup systems less relevant. However, for the near term, requiring MNOs to install batteries or alternative power sources ensures communication lifelines stay open during emergencies. This approach mirrors similar resilience efforts in other European nations following recent grid failures.

Spain's move reflects a broader EU push toward digital infrastructure resilience. By mandating backup power for mobile networks, the country aims to prevent communication breakdowns that can complicate emergency response and leave citizens isolated during critical situations.
