Cuba Suffers Third Nationwide Blackout of 2026 as Fuel Blockade Grinds On

Cuba's national power grid collapsed again on July 7, 2026, plunging the island into a total blackout for the third time in six months. Unión Eléctrica de Cuba gave no immediate explanation for the failure, which followed the same pattern as prior collapses in early 2026: fuel-starved thermoelectric plants lacking the reserve capacity to absorb a single unit tripping offline. The outage came less than a week after the UN human rights chief warned that the US oil blockade was directly causing child deaths on the island, and as daily rolling blackouts outside the total collapses continued to run 20+ hours in much of the country.
