Cuba Faces Fourth Nationwide Blackout in Six Months, Leaving Millions Without Power

A failure at a Havana substation triggered a grid collapse, highlighting aging infrastructure and economic challenges.

The blackout began Friday evening after a failure at the Diezmero substation in Havana caused a chain reaction that shut down Cuba's national grid.
This marks the fourth major power outage in six months, with experts citing aging infrastructure and fuel shortages as key contributors.
Hospitals and other essential services are being prioritized with limited power through parallel circuits and generator units.
Residents across Cuba, including rural areas already suffering from prolonged rolling blackouts, face uncertainty about when power will be fully restored.
The outage underscores Cuba's broader economic crisis, worsened by U.S. sanctions, fuel shortages, and reliance on outdated power plants.
