Summary

Cuba’s national electrical grid collapsed Friday night, causing widespread blackouts in Havana and across the country.

The energy ministry blamed a failed substation in the capital for triggering the outage, which affected internet service and left millions without power.

Cuba’s aging energy system, already strained by fuel shortages and economic hardship, has faced frequent blackouts. Authorities are working to restore power and expand solar energy projects.

Previous outages have led to anti-government protests, as Cubans struggle with worsening shortages of food, medicine, and water.
