Cuba suffers third nationwide blackout in six months amid worsening fuel shortages

Cuba suffered a total disconnection of its national electricity system on Monday, according to the state electricity company, in the country's third nationwide blackout since the start of the year. The outage affected the island's power grid as authorities said they were investigating the cause. The incident adds to a prolonged energy crisis that has left many parts of the country facing repeated and extended cuts.

The utility said there had been a "total disconnection from the national electricity generation system" and said it was examining what had happened. The blackout is the eighth on the island of 9.6 million people since late 2024, underscoring the fragility of the grid. Authorities have already been imposing severe rationing, with some areas of Havana experiencing power cuts lasting more than 24 hours and some rural areas going without electricity for more than 70 hours.

The latest failure comes as the government tries to conserve scarce fuel for generators that support the national grid. The electricity system is heavily dependent on ageing Soviet-era plants, which have been under strain for years. Officials have also been trying to expand solar power, but it still accounts for only a small share of the energy mix.

The repeated outages have disrupted daily life and deepened pressure on households, businesses and public services. The blackout is significant because electricity shortages have become one of the clearest signs of Cuba's wider economic stress. Fuel scarcity has worsened since January, when the supply available for power generation was further reduced.

The situation has also fed concerns about food, drinking water and medicine, which have already been described as increasingly short in supply. In that context, a nationwide grid failure is not only a technical problem but also a broader humanitarian and governance challenge. The island's power system has long been vulnerable, but the pace of blackouts has accelerated in recent months.

The state has blamed a lack of fuel for the generators needed to stabilise the grid, while the country's ageing infrastructure has struggled to cope with demand. The latest outage also comes against the backdrop of tighter external pressure on the Cuban economy, including sanctions and restrictions affecting energy imports and foreign companies. What remains unclear is what triggered the latest disconnection and how quickly power can be restored across the island.

The electricity company said it was investigating, but gave no immediate timeline for recovery. The key question now is whether the grid can be stabilised without another prolonged outage, and whether fuel shortages will continue to drive further nationwide failures. For households and essential services, the immediate concern is how long the disruption will last and whether more cuts will follow.
