Cuba experienced a total nationwide power outage starting Sunday night and continuing into Monday [1].

The blackout underscores the fragility of the island's energy infrastructure and the deepening economic crisis affecting millions of residents, including those in the capital city of Havana [2].

The Empresa Eléctrica Nacional described the event as a "déconnexion totale du système électrique national" [3]. The failure affected the entire island, leaving cities and rural areas without electricity as the national grid collapsed [2].

According to the Cuban Ministry of Energy and Mines, officials are currently implementing "tous les protocoles pour le rétablissement du système électrique" [4]. This incident marks the sixth nationwide power outage recorded so far this year [5].

Cuban authorities attribute the recurring failures to the U.S. oil embargo. They said the sanctions limit the fuel supplies necessary to keep power plants operational, which in turn exacerbates the energy crisis [6].

Reports indicate that power cuts have become more frequent and severe as the government struggles to secure stable energy imports. A Radio-Canada reporter said, "Les coupures de courant se sont aggravées depuis que Washington a imposé un blocus pétrolier qui complique l'approvisionnement des centrales électriques" [7].

The outage began during the night of Aug. 2 and persisted into the morning of Aug. 3 [1]. While the Ministry of Energy and Mines continues restoration efforts, the frequency of these total grid collapses suggests a systemic failure of the national electrical system [5].

The recurrence of total grid collapses, six times within a single year, indicates that Cuba's energy sector is in a state of critical instability. By linking these failures to the U.S. embargo, the Cuban government highlights the external pressures on its economy, but the frequency of these events also suggests an inability to diversify energy sources or maintain aging infrastructure under current economic constraints.
