Cuba restores power grid after second nationwide blackout in a week

HAVANA: Cuba's national power grid was restored on Saturday, officials confirmed, following the second complete blackout to hit the island nation within a single week, as the country continues to grapple with a deepening energy crisis compounded by a US oil embargo.

The latest nationwide power outage struck on Friday, plunging the entire island into darkness and leaving millions of Cubans without electricity. Authorities worked through the night to bring the grid back online, with officials announcing the restoration of power a day after the blackout began.

Recurring power failures highlight deepening crisis

The blackout was the second such incident in the span of just one week, underscoring the fragile state of Cuba's aging electrical infrastructure. The crisis-hit Caribbean nation has been struggling to maintain a stable power supply amid severe fuel shortages linked to US sanctions on oil supplies to the island.

Images from the capital Havana showed residents walking through darkened streets during the nationwide outage on March 21, 2026, as the city and the rest of the country were left without power.

US oil sanctions exacerbate energy woes

Cuba's recurring blackouts have been closely tied to the impact of a US oil embargo, which has severely restricted the island's access to fuel needed to operate its power plants. The energy crisis has become one of the most pressing challenges facing the Cuban government, with repeated failures of the national grid affecting daily life across the country.

The restoration of the power grid brings temporary relief to the island's approximately 11 million residents, though the underlying causes of the energy instability — including aging infrastructure and constrained fuel supplies — remain unresolved.

The frequency of nationwide blackouts has increased in recent times, with Cuba experiencing multiple total grid failures that have disrupted homes, hospitals, businesses, and essential services across the island. The repeated outages have added to the broader economic hardships faced by ordinary Cubans, who are already dealing with shortages of food, medicine, and other basic necessities.

While power has been restored following the latest incident, there remains significant concern over how long the grid will hold, given the persistent structural challenges plaguing Cuba's energy sector. The situation continues to draw international attention as the island navigates one of its most difficult periods in recent memory.
