Cuba's electrical grid collapsed for the fourth time in 48 hours on Sunday, further deepening the island's ongoing energy crisis as Hurricane Oscar made landfall. Millions of residents remain without power after the initial grid failure on Friday, as strong winds and heavy rains threaten to exacerbate an already dire situation.

Hurricane Oscar struck the eastern part of the island with 75 mph winds, storm surges, and torrential rain, raising alarms over the "extremely dangerous situation," according to Cuba's meteorological agency. The U.S. National Hurricane Center also confirmed that the storm is expected to continue across Cuba and move toward the Bahamas by Tuesday.

Cuban authorities have scrambled to restore electricity but faced repeated setbacks. The energy and mines ministry said that restoration efforts had begun "immediately," though progress has been slow. By Sunday, power was restored to 160,000 customers in Havana, but another collapse later in the day dashed hopes for a quick resolution.

Cuban Energy Minister Vicente de la O Levy remained cautious, stating that while power could be fully restored by Monday or Tuesday, residents should not expect substantial improvements. The situation has left many struggling, as widespread outages continue to disrupt daily life, including essential services like food storage and communication.

The government canceled schools through Wednesday and advised that only essential workers report to duty. Protests erupted in Havana following the weekend's grid failures, with videos circulating on social media showing small demonstrations, though the government downplayed these incidents as "isolated and minimal."

In addition to hurricane damage, Cuba's fragile power grid has been plagued by fuel shortages, deteriorating infrastructure, and rising energy demands. The U.S. trade embargo and sanctions imposed by former President Donald Trump have further hindered Cuba's ability to import fuel and spare parts for its aging, oil-powered plants.

Cuba, which relies on fuel imports to sustain its energy infrastructure, has faced dwindling supplies from key allies like Venezuela and Mexico. Venezuelan fuel deliveries have dropped by half this year, and Mexico’s newly elected President Claudia Sheinbaum has yet to clarify whether her administration will continue supporting Cuba with subsidized fuel.

As the country battles the immediate aftermath of Hurricane Oscar and ongoing power outages, residents like Anabel Gonzalez from Havana are growing desperate. "My cell phone is dead, and everything in my fridge has spoiled," she said, echoing the frustrations of many islanders grappling with food, fuel, and medicine shortages amid this cascading crisis.
