Havana: Power blackout has once again affected Cuba after the national electric grid collapsed for the second time within a week, intensifying concerns over the country’s fragile energy system.
Officials have confirmed that a total disconnection of the national power system occurred on Saturday evening, leaving large parts of the island without electricity. The outage has marked the third major failure this month, following earlier disruptions on March 4 and earlier in the same week.
The latest collapse has come as Cuba continues to face severe fuel shortages linked to a tightening oil supply situation. The United States has imposed restrictions that have cut off key fuel sources, including oil shipments that previously came from Venezuela under favourable terms.
The loss of Venezuelan support has significantly impacted Cuba’s energy sector. In addition, Mexico, another major supplier, has halted oil shipments, further limiting fuel availability. These developments have made it increasingly difficult for authorities to maintain consistent electricity generation.
The situation has been worsened by ageing infrastructure. Cuba’s power grid relies heavily on older thermoelectric plants, one of which failed earlier this month, triggering a widespread outage. The combination of outdated facilities and limited fuel has created ongoing instability in electricity supply.
Authorities have warned that even when power is restored, shortages may continue due to insufficient generation capacity. Residents across the country have already been experiencing prolonged daily outages, with many areas facing more than 16 hours without electricity.
The broader global energy situation has also added pressure. Rising oil prices linked to ongoing geopolitical tensions have increased costs and reduced access to alternative supplies. Despite temporary adjustments in global sanctions policies, Cuba has remained excluded from certain oil trade channels.
The repeated power blackout events have underscored the severity of the country’s energy crisis. With limited fuel, ageing infrastructure and rising demand, the outlook for stable electricity supply remains uncertain.
