Cuba's national power grid has suffered a "total disconnection", operator UNE said on X.

"Total collapse of the National Electric System," UNE said on Friday at 4.30 pm local time (2030GMT), without providing the cause of the outage.

This is the second nationwide blackout in less than a week, after one on July 6.

Cuba grapples with its worst economic crisis in decades, including severe fuel shortages and repeated power failures.

Official media reported that the economy contracted sharply in the first half of 2026, while average daily power outages have reached 20 hours, and the electricity deficit climbed to 1,955 megawatts.
