Cuba's Electrical Grid Collapse Triggers Blackouts, Protests, and Economic Strain

Widespread Power Outages and Their Impact on Cuba

By Dave Sherwood

Partial Grid Collapse and Immediate Aftermath

HAVANA, May 14 (Reuters) - Cuba's electrical grid suffered a partial collapse early on Thursday morning, the country's grid operator UNE said, snuffing out power across eastern Cuba and testing the patience of Cubans already exhausted from seemingly interminable blackouts amid a U.S. fuel blockade.

By mid-morning officials had restored power to some essential services in the region, the grid operator said, though much of Cuba east of Camaguey, including the island's second-largest city, Santiago de Cuba, remained largely without electricity.

Escalating Blackouts Amid Rising Temperatures

The Caribbean island of nearly 10 million people has reached a tipping point this month, as summer heat sets in and the vast majority - including in the capital Havana - now suffer without electricity for 20 hours or more each day.

International Factors and Fuel Shortages

U.S. Policies and Their Consequences

The blackouts dramatically worsened in January after U.S. President Donald Trump threatened tariffs on any nation supplying the island with fuel. Venezuela and Mexico, once the country's top suppliers of crude oil, have since cut off shipments.

Trump has predicted Cuba would "collapse" and has said he wants to oust the current communist-run government.

Government Response and Blame on Blockade

Cuba's energy and mines minister said on Wednesday that the island had completely run out of fuel oil and diesel, both critical to powering the island's electrical grid, and blamed blackouts on the U.S. blockade.

Social Unrest and Economic Fallout

Protests and Public Sentiment

Widespread protests broke out across Havana on Wednesday evening as the power cuts in some parts of the city spanned 24 hours or more, threatening to spoil frozen food reserves and making sleep all but impossible for many residents.

Voices from the Ground

"The country has no fuel and that's no lie," said Rodolfo Aragon, a 55-year-old small business owner who said he saw little hope for the future amid Cuba's conflict with the United States. "Our economy has hit rock bottom."

International Reactions

The United Nations last week called Trump's fuel blockade unlawful, saying it had obstructed the "Cuban people’s right to development while undermining their ​rights to food, education, health, and water and sanitation."
