Cuba's Power System Fails Again, Leaving Millions in the Dark

Cuba's national energy system has collapsed entirely, plunging an estimated 10 million people into darkness. The Cuban Electric Company announced the nationwide blackout and stated that investigations into the cause are underway.

This latest outage adds to a period of severe energy instability on the island. For months, Cubans have endured lengthy, and increasingly multi-day, blackouts. These disruptions are attributed to a combination of an aging and deteriorating power grid and the impact of U.S. sanctions, which have restricted the supply of essential fuel.

This is not the first time the country has faced such a widespread failure. A complete blackout also occurred in the fall of 2024, with two such incidents happening in less than a 24-hour period. Another major outage struck the island in March 2026, highlighting the persistent challenges facing Cuba's energy infrastructure.
