Cuba had four electric grid collapses since Friday, and most of the country remains in the dark as slow progress is made to restore power.

Cuba's efforts to restore power to the island were derailed for a third time late on Saturday, Cuban authorities said shortly before midnight, leaving millions in the dark and raising fresh questions over the viability of the government's bid to reestablish electrical service.

Many of Cuba’s power plants are outdated and inefficient; some have been in operation for over 50 years without proper maintenance. After the country’s grid collapsed when hurricane Ian hit in 2022, experts warned the government needed to urgently invest in modernizing the system.

Cubans experienced their second black out wave Saturday after government officials said they were working to restore electrical service to hospitals and crucial service centers after a grid failure on Friday.
