HAVANA — An islandwide blackout struck Cuba on Friday for the second time this week as the nation of nearly 10 million people grapples with a crumbling power grid and fuel shortages stemming from a U.S. energy blockade.

While total blackouts have become increasingly common in the Caribbean country, it’s unusual for back-to-back ones to hit just days apart. Cuba’s Electric Union confirmed the outage on X.

Officials had also confirmed the first total power outage, which happened on Monday, although it wasn’t clear what caused it. Authorities at the time said an investigation was underway.

Fuel has been running out across Cuba since January, when U.S. President Donald Trump threatened tariffs on any country that sells or provides oil to the island, deepening the island’s ongoing economic and financial crisis. Public transportation has largely been halted, and officials have cancelled tens of thousands of surgeries.

Cuba produces only 40 per cent of the fuel it needs, while the 730,000 barrels of oil delivered by a Russian tanker in late March ran out by the end of April. The government also has been rationing power with intentional outages that can stretch to more than 24 consecutive hours.

A blackout in mid-May affected the island’s eastern provinces, while a blackout in mid-March struck the entire island.
