Cuba’s National Grid Collapse Triggers Island-wide Blackout

The Collapse on August 2-3, 2026
Late on Sunday, August 2, the state-owned Union Electrica de Cuba (UEC) announced that the national electricity grid had collapsed, leaving the island of roughly 10 million residents without power. The outage persisted into Monday, August 3, as streets of Havana were illuminated only by flashlights and vehicle headlights. UEC provided no further details on the cause, extent of damage, or timeline for restoration.
Background & Context
Cuba has endured a series of nationwide blackouts this summer. Three separate outages occurred in July, including a major failure on July 14 that marked the third blackout within nine days. The frequency of these events has risen as the island’s aging energy infrastructure confronts severe fuel shortages.
The crisis is linked to a U.S. oil blockade imposed by President Donald Trump after the January 3 ouster of Venezuelan President Nicolás Maduro. Venezuela had long supplied the bulk of Cuba’s crude oil; the blockade eliminated that source, and Mexico subsequently halted its own exports under increased U.S. pressure. With limited access to fuel, power plants have struggled to operate, and many generating units are over 30 years old and have received minimal maintenance.
Amid the shortages, Havana has begun a cautious opening of its tightly controlled energy sector. The government recently authorized its first foreign-backed fuel-import venture and permitted nearly 200 Cuban businesses to participate in wholesale fuel distribution, aiming to mitigate the supply gap.
Data & Statistics
- Population affected: about 10 million people.
- Recent blackouts: three nationwide outages in July; three collapses within a nine-day span, including the July 14 event.
- Fuel import disruption: loss of Venezuelan oil after the January 3 blockade; cessation of Mexican shipments.
- Economic opening: roughly 200 Cuban firms now involved in wholesale fuel distribution.
- Infrastructure age: several thermoelectric plants exceed 30 years with limited upkeep.
Official Statements & Responses
The Cuban energy ministry echoed the description of a complete system shutdown. Government officials have attributed the crisis to the U.S.
In response to the broader economic impact, Cuban Vice President Salvador Marrero told reporters that reforms are underway:
“The results will be achieved gradually,” — Marrero
Marrero emphasized that the reforms will unfold gradually, acknowledging the difficulty of the current stage.
Conflicting Reports & Gaps
While all sources confirm the blackout’s scope and timing, no outlet has identified a definitive technical cause for the August collapse. The utility’s statements lack details on restoration schedules, and on-the-ground reports vary regarding the duration of power loss in different municipalities. The absence of a clear timeline leaves uncertainty about when essential services—hospitals, water treatment, and communications—will be fully restored.
