HAVANA — Cuba's national power grid collapsed on September 18, 2026, leaving more than 9 million people without electricity in the twelfth nationwide blackout the island has suffered since late 2024. Cuba's Ministry of Energy and Mines announced the outage on social media without specifying a cause, saying restoration protocols were being activated.

The blackout is part of a worsening pattern that has intensified since the United States imposed an energy blockade in January 2026, cutting off fuel shipments to Cuba and preventing the country from importing the fuel and parts needed to keep its thermoelectric plants running. It marked at least the sixth nationwide blackout since January.

Cuban authorities have not said when power will be fully restored. The recurring collapses have strained daily life across the island, affecting water pumping, communications and refrigeration, as the government continues to grapple with an aging power generation system already weakened by years of underinvestment.
