Cuba reconnected its national electrical grid and restored power to the majority of the capital Havana by late on Sunday, energy officials said, nearly two days after an island-wide outage knocked out power to 10 million people.

Cuba restored power to most of Havana after a nationwide outage affected 10 million people. The grid collapse was triggered by a shorted transmission line. Oil-fired plants are back online, yet Cuba faces ongoing energy issues due to outdated infrastructure and geopolitical tensions.

Havana’s streets plunged into darkness once again as a general blackout hit Cuba. Writing on the social network X, Cuban PM Manuel Marrero Cruz said the government was "working tirelessly" to restore power.
