Cuba experienced yet another major blackout on August 3, 2026, with its entire electricity grid collapsing for the fourth time this month. The nationwide outage included Havana, the capital, as confirmed by the country's state-owned utility. Officials from the electricity authority stated that the national system had undergone a total disconnection, leaving all 10 million Cubans without power at once.
The recurring power outages are being blamed on a mix of outdated energy systems and a tightening oil supply crisis. The island still depends on oil-fired power plants, many of which are decades old and in need of upgrades. But fuel deliveries have been severely disrupted.
Cuba then shifted to Mexico as a secondary source for fuel, but US pressure led to a suspension of those deliveries as well. In March, the country received one major supply of oil from a Russian tanker under US approval. But even that emergency shipment has now run out, leaving the energy system on the brink.
Expanded Economic Pressure from Washington
In addition to targeting energy supplies, the US is increasing broader economic pressure on Cuba. The Trump administration has intensified sanctions against government-owned businesses, leading to a wave of foreign firms halting their work in the country. These actions have added to the hardships faced by the Cuban people, particularly as basic services are disrupted.
Cuba remains on the US list of state sponsors of terrorism, a label it received again in 2025. President Joe Biden had earlier begun the process to remove it from the list, but the Trump administration quickly reversed the move. The renewed classification has complicated Cuba’s efforts to attract international investment and support.
Amid these pressures, Cuban officials are working to restore the national grid. The Ministry of Energy said that restoration protocols were in full operation, but the scale of the challenge remains enormous, with water and cooling systems also affected due to the outages. The crisis underscores how tightly linked Cuba’s economic stability is to external factors, especially decisions by the US government.
