Cuba's national electric grid collapses, reason unknown

Nationwide Blackout Leaves Millions Without Power

By Dave Sherwood

Incident Overview

HAVANA, July 6 (Reuters) - Cuba's national electric grid collapsed on Monday at midday, the country's grid operator said, leaving around 10 million people on the Caribbean island without power.

Response from Grid Operator

Grid operator UNE said it was investigating the cause of the nationwide blackout.

Background and Contributing Factors

Ongoing Power Outages

Cuba has for months suffered from hours-long, and more recently, days-long power outages linked in part to a decrepit grid and a U.S. imposed oil blockade that has cut off the island's fuel supply.

Impact on Daily Life

The nationwide outage is more bad news for Cubans already exhausted from rolling blackouts that make it impossible for many to work or sleep in the Caribbean summer heat.

Economic Crisis and Political Pressure

Cuba has ​frequently struggled to keep the lights on during a years-long economic crisis but the Communist-run government has entered unprecedented territory under increased pressure from U.S. President Donald Trump.

Extent of the Blackout

Nearly two-thirds of the country was already without power when the grid collapsed on Monday.
