Cuba Plunged Into Darkness as the Power Grid Fails Again

At about 2 p.m. local time on Friday, the lights went out across Cuba. A sudden failure in high‑voltage transmission lines in the island’s centre triggered a total grid collapse, sending the whole country into darkness.

Officials from the National Electrical Union (UNE) said they were already prepared for a “gradual restoration” once the fault was isolated. Still, the picture on the ground was grim: streets in Havana, usually flickering with neon, were eerily silent, and the occasional glow from emergency generators barely lit a few hospital corridors.

It isn’t the first time this year the nation has been knocked off the grid. Since January, there have been at least six partial or total blackouts, each one a reminder of an aging power system that is being squeezed by chronic fuel shortages. The latest episode felt especially harsh because it arrived after a rain‑soaked evening, when people were already huddling under blankets, hoping the power would stay on long enough to charge a phone or boil some water.

“Yesterday I went a whole day without electricity. They turned the lights back on for an hour and then everything went dark again,” said 23‑year‑old Frank Lorenzo, a resident of Havana. He laughed nervously, swatting at a mosquito, while the sky above the capital was a cloudy, overcast blanket.

The root of the problem, analysts say, is a combination of decrepit infrastructure and a U.S.‑imposed oil blockade that began in January. The embargo has sharply limited the island’s access to fuel, forcing power plants to run on lower‑quality crude or, in some cases, to shut down altogether. That scarcity makes the grid far more fragile, and a single line failure can cascade into a nationwide outage.

In July, the grid gave way three separate times, and rolling blackouts that lasted 30 hours or more have become almost routine in many provinces. Residents have learned to live with candles, battery‑powered radios, and the occasional community generator, but each new blackout chips away at morale.

The United Nations has weighed in, with human‑rights experts condemning the U.S. oil blockade as a violation of international law. They warned that Cuba risks becoming a “silent Gaza,” a place where shortages and power cuts turn everyday life into a battle for basic survival.

By late evening, power was creeping back into a handful of neighborhoods in Havana, mainly around hospitals and essential services. Yet large swaths of the city remained black, the rain hammering against rooftops that were now lit only by streetlamps that had somehow survived the outage.

For many Cubans, the blackout is less a surprise than an unwanted affirmation that the island’s energy crisis is deepening. The hope, if any, is that international pressure might ease the embargo, allowing the country to import the fuel it desperately needs to keep the lights on.
