At 6:32 pm on Saturday, the lights went out across Cuba. All of them.

The national electric grid suffered what state power authorities called a “total disconnection” — the second nationwide collapse in less than a week, the third this month. For nearly 10 million people, the darkness was immediate and total.

A System in Terminal Decline

This is not a fluke. It is a pattern.

Power outages have become routine in Cuba over the past two years as the island’s electricity generation system — much of it built during the Soviet era — has broken down faster than it can be repaired. Regional blackouts stretch to 20 hours in some provinces. The nationwide collapses are a newer and more alarming phenomenon.

Cuba produces roughly 40% of the fuel it needs to power its economy. The rest has to come from somewhere else. Since January 9, it has come from nowhere.

The Oil Blockade

The immediate cause of Cuba’s fuel crisis is geopolitical. In January, the Trump administration severed Venezuelan oil exports to Cuba after Washington deposed Venezuelan President Nicolás Maduro — Havana’s principal ally and energy supplier. The administration has threatened other nations with punitive tariffs if they sell oil to Cuba.

The result: no oil has reached Cuban shores in over ten weeks.

Cuban officials blame the US trade embargo for the grid collapse. Washington attributes the failures to Cuba’s Soviet-style command economy. Both are partially correct. Aging infrastructure doesn’t repair itself, but infrastructure also doesn’t run without fuel.

What Darkness Means

A national blackout is not merely an inconvenience. Hospitals operate on backup generators, if they have them. Fuel for those generators is also running low. Water pumps fail without electricity, leaving urban centers without running water. Food spoils. Communications cut out.

Cuba’s tourism sector — a critical source of foreign currency — has been hit hard. Airlines have curtailed flights to the island. Hotels cannot guarantee power for guests. The economic damage compounds the energy crisis, which compounds the economic damage.

The Political Stakes

The Trump administration has demanded that Cuba release political prisoners and move toward political and economic liberalization in exchange for sanctions relief. It has also raised the possibility of what President Trump calls a “friendly takeover” of the island — a phrase that has not been welcomed in Havana.

For now, there is no indication that either side is prepared to shift position. The blackouts will likely continue.

Cuba is living through the convergence of decaying infrastructure, economic isolation, and geopolitical pressure. The result is visible from space: an island of ten million people, blinking out, one grid collapse at a time.
