Cuba suffered a total nationwide power outage on Monday, July 6, starting at 12:17 local time [1].
This collapse of the National Electroenergetic System marks a deepening energy crisis for the island. Frequent blackouts disrupt essential services, healthcare, and daily life for millions of citizens already facing economic instability.
The outage is the third total blackout to occur in 2026 [2] and the eighth such event in the last 24 months [1]. A spokesperson for the Cuban government said a total disconnection of the system occurred and that the causes are currently under investigation [1].
Government officials said the current situation is "critical" [1]. While the exact cause of Monday's failure is not yet confirmed, officials cited a crisis in thermal power plants and a block in oil supplies as contributing factors to the instability [3, 4, 5].
The impact of the outage has varied by region. In Havana, power cuts lasted more than 35 hours [1]. Other regions of the island experienced more severe disruptions, with some areas remaining without electricity for up to three days [1].
Earlier forecasts indicated the severity of the grid's instability, with estimates suggesting that 64% of the country would be without power on Monday [6]. The government has not provided a definitive timeline for the full restoration of all services across the island.
“The situation is “critical.””
The increasing frequency of total grid collapses—eight in two years—suggests a systemic failure of Cuba's energy infrastructure. The reliance on aging thermal plants and the vulnerability to oil supply disruptions create a volatile environment where the national grid cannot sustain basic demand, leading to prolonged outages that paralyze the country's capital and rural provinces alike.
