Entire grid goes dark across Cuba

Cuba's electricity system suffered total disconnection on Friday, leaving millions without power. It's the sixth major blackout to hit the island this year.

Transmission fault triggers nationwide outage

The blackout started just before 2 PM local time on Friday due to a transmission fault combined with poor weather in central Cuba. Power was restored to priority areas like hospitals by late evening.

US oil blockade starves the island

Cuba relies on fuel imports but faces a US oil blockade since the start of the year. Sanctions have cut off supplies and threatened countries shipping oil to Havana.

Venezuela's oil supply dried up

Venezuela's oil supply dried up

Venezuela once sent Cuba about 35,000 barrels of oil daily, covering half its needs. But Venezuela's own supplies were cut off after the US seized President Nicolás Maduro in January.

Cubans struggle with cascading shortages

Repeated blackouts have left residents without water, gas, or electricity for days at a time. Hospitals struggle to function and schools have closed, prompting rare public protests.

“Lately, it's becoming a habit. Before it happened less frequently - once a month.”

Trump threatens more pressure on Cuba

The Trump administration has announced new sanctions and threatened tariffs on countries shipping oil to Havana. Trump has openly discussed toppling Cuba's leadership, including a potential military takeover.

In short

Cuba's electricity crisis stems from a combination of aging infrastructure, chronic fuel shortages worsened by US oil sanctions, and the loss of Venezuelan oil supplies.
