Cuba experienced a total nationwide blackout on Friday, July 10, 2026, after the national electric grid collapsed [1].
This failure marks the second total blackout in a single week [1]. The repeated collapse of the power system disrupts essential services and daily life across the island, highlighting the fragility of the nation's energy infrastructure.
The outage began at 6:38 p.m. local time [4]. According to the Ministry of Energy and Mines, the event was a "total disconnection of the National Electroenergetic System" [2]. The blackout affected the entire island, with reports of power loss spanning from Havana to eastern provinces, including Ciego de Ávila, and Guantánamo [3].
Fuel shortages are the primary driver of the crisis. The blackout was triggered by a severe lack of diesel and fuel oil, which has left the aging power-generation system unable to operate [5]. Some reports indicate that Cuba has been left with zero diesel and fuel oil due to the impact of the U.S. oil embargo [5].
Residents described a sense of helplessness as the grid failed. "When the SEN (National Electric Energy System) falls, there is no other option: you sit on the sidewalk and wait," Juan Carlos, a resident, said [1].
The frequency of these failures is increasing. This event represents the fourth collapse of the grid this year [1]. Other reports state that the island has suffered seven blackouts in the last year and a half [4]. Earlier this year, the system reportedly collapsed three times in March [2].
“"When the SEN falls, there is no other option: you sit on the sidewalk and wait,"”
The recurring collapse of Cuba's electrical grid demonstrates a critical intersection between aging infrastructure and geopolitical pressures. Because the island relies on imported fuel to power its plants, the US oil embargo creates a direct bottleneck that prevents the Ministry of Energy and Mines from maintaining basic stability. These total blackouts suggest that the system has reached a breaking point where it can no longer absorb fuel shocks without a complete national failure.
