What happened

Some supportReported by 1 outlet

Cuba's national electrical grid collapsed on September 21, 2026, cutting power to over 9 million people in Havana and Matanzas. The failure originated in high-voltage transmission lines in the west, causing the eastern grid to disconnect. This collapse occurred one day after the US State Department announced new sanctions targeting eight Cuban entities and three individuals.

Cuban authorities estimate the damage from the blockade between March 2025 and February 2026 to be more than $8 billion. Furthermore, the UN projects that the Cuban economy will contract 6.5 percent this year, which is the steepest decline in the region.
