Cuba was plunged into an island-wide blackout on Monday, a direct consequence of dwindling fuel reserves and a deteriorating national electric grid, leaving 10 million people without power.
The state-run Electric Union announced the widespread failure on X, stating an investigation into the cause is underway.
The Ministry of Energy and Mines confirmed on X it has initiated protocols to restore electricity.
This latest power crisis comes amid severe fuel shortages that have plagued Cuba since January.
The situation worsened after Donald Trump threatened tariffs on any country providing oil to the island, exacerbating an already profound economic and financial crisis.
The scarcity has led to widespread disruptions, including halted public transportation and the cancellation of tens of thousands of surgeries.
Cuba’s domestic fuel production meets only 40 percent of its needs. A significant delivery of 730,000 barrels of oil by a Russian tanker in late March was depleted by the end of April.
The government has resorted to rationing power through intentional outages, some lasting over 24 consecutive hours.
This incident follows previous blackouts, including one in mid-May affecting eastern provinces and another in mid-March that impacted the entire island.
