MADRID, June 25 (Reuters) – Spain will require mobile operators to keep at least four hours ‌of network coverage for most of the population ‌in case of power outages under a new decree to be ​approved before year-end, Digital Transformation Minister Oscar Lopez announced on Thursday.

• Mobile networks went down across Spain during a crippling blackout in April 2025 that affected ‌Portugal and Spain.

• Coverage ⁠will be phased in over three years: half of Spain’s population to be covered ⁠in the first year, 65% in the second, and 75% by year three.

• The minister did not provide ​cost estimates ​of the plan that ​would involve installing batteries ‌or other power back-up systems throughout the mobile communications infrastructure.

• The rules apply to telecoms operators and digital infrastructure providers — including submarine cables, satellite systems, data centres and internet exchange points — serving more than 500,000 ‌users or generating more than €50 ​million ($56.80 million) in annual revenue.

• ​Mid-tier network management centres ​must remain operational for at least ‌12 hours without power; top-tier ​control centres, whose ​failure could affect the entire country, must guarantee 24 hours of operability.

• Emergency call centres must ​draw up ‌security and resilience plans, with backup communication channels, ​under the decree.
