Electricity has been restored to half of Havana, the Cuban capital's power company reported Monday, four days after the start of a nationwide blackout that the authorities have struggled to address.The government has said that electricity is expected to be restored to most of the country by the end of Monday.

Havana: Some electricity was restored in Cuba, the government said Saturday, after the island nation's worst blackout in at least two years kicked in when a major power plant failed and left millions without electricity for two days.

Millions in Cuba faced another morning without power on Sunday following a third partial grid failure in two days, intensifying a crisis that has left residents struggling with blackouts and shortages. The latest collapse affected the western provinces, including Havana, where the entire capital was plunged into darkness overnight.

Many of Cuba’s power plants are outdated and inefficient; some have been in operation for over 50 years without proper maintenance.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.

Some electricity was restored in Cuba after the island nation’s worst blackout in at least two years left millions without electricity for two days. Energy Minister Vicente de la O Levy said Saturday the country had 500 megawatts in its electrical grid early Saturday,

Some neighborhoods had electricity restored in Cuba’s capital, where 2 million people live, but most of Havana remained dark. The impact of the blackout goes beyond lighting, as services like the water supply also depend on electricity to run pumps.

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.

Friday’s supply collapse was unprecedented in modern times, aside from incidents involving intense hurricanes, like one in 2022.
