Cuba experiences an island-wide power outage for a third time in six months on Monday, leaving nearly 10 million people without electricity while officials work to restore service. Multiple outlets cite the state electricity company, Unión Eléctrica (UNE), saying there is a “total disconnection” from the national electricity generation system, and that it is investigating the cause. CBS and other reports describe power being restored gradually after the blackout. The outages come amid a worsening energy crisis affecting the country’s ageing generation infrastructure and fuel supply. Several sources say Cuba was already struggling to keep the lights on before the United States tightened measures against the island, including actions linked to reduced oil imports. They report that after a US oil blockade and related fuel restrictions, Cuba’s power plants run with dwindling supplies, accelerating grid instability. Authorities also impose extended power cuts in parts of Havana and rural areas to conserve fuel. In addition to restoration efforts, the government continues energy measures including expanded solar power, though it remains a minority share of generation. The UN and others have previously warned about broader humanitarian conditions tied to the crisis.
