Millions of Cubans remain without power after substation failure

Millions of people in Cuba remain without power after a failure of the nation’s electric grid left the island in the dark the previous night.

The massive blackout is the fourth in the last six months as a severe economic crisis plagues the Caribbean country.

The ministry of energy and mines, in a statement on social media, attributed the latest outage to a failure at a substation in the suburbs of Havana, the capital.

Lazaro Guerra, director of electricity at the ministry, said on national television that power was already being generated to support vital services such as hospitals.

A statement from the Cuban Electricity Union released on Saturday said the strategy was to create “microsystems” that will connect to each other to gradually restore electricity across the country.

Several of these were already operating in the provinces of Guantánamo, Santiago, Las Tunas and Pinar del Rio.

Internet and telephone service were intermittent more than 12 hours after power went out around 8pm local time on Friday (12am on Saturday GMT).

Cuba suffered similar blackouts in October, November and December. The latest was the first of 2025 but in mid-February authorities suspended classes and work activities for two days due to a shortage of electricity generation that exceeded 50% in the country.

Experts have said the electricity disruptions are a result of fuel shortages at power plants and aging infrastructure. Most plants have been in operation for more than 30 years.

The outages come as Cubans are experiencing a severe economic crisis that analysts have blamed on the effects of the Covid-19 pandemic, a programme of domestic measures that triggered inflation and, above all, the tightening of sanctions by the United States.

Many Cuban families use electric equipment to prepare their meals. The outage could cause food to thaw in refrigerators and possibly spoil due to the island’s tropical climate.
