Cuba restored its national power grid on Thursday, July 11, after an island-wide blackout disrupted services for nearly 10 million people [2].

The outage highlights the fragility of the nation's energy infrastructure and the severe impact of fuel shortages on basic municipal services. The crisis has left residents struggling with food scarcity and a breakdown in waste management.

The blackout began on Monday, July 7 [3]. The state-run Electric Union said the event was a "total disconnection of the island's power grid" [1]. According to an official from the Energy Ministry, the country had been "living in darkness for 16 hours" [4] before the grid was brought back online.

Cuban officials and reports attribute the collapse to a U.S. oil blockade that has depleted fuel reserves and strained the national grid [5]. While some reports link the event generally to dwindling fuel reserves, others said the blockade is the direct cause [5].

The lack of electricity and fuel triggered a cascade of other failures across the island. In cities such as Havana and Santiago de Cuba, residents reported an accumulation of uncollected trash as sanitation services failed [6]. With power and cooking gas unavailable, many families turned to charcoal for heating and preparing meals [6].

Residents described a desperate situation on the ground. One anonymous Cuban resident said, "There is little food, power, fuel or relief" [7]. The combination of hunger, crime, and infrastructure collapse has particularly affected the elderly population [6].

“Total disconnection of the island's power grid.”

This incident underscores the systemic vulnerability of Cuba's energy sector to external trade pressures. The rapid transition from a power failure to a broader humanitarian crisis—marked by waste accumulation and food insecurity—demonstrates how fuel dependency creates a single point of failure for the island's entire municipal infrastructure.
