Cuba's power-grid operator said it had restored electricity to parts of the capital Havana on Monday following a fourth major grid failure in 48 hours, while Tropical Storm Oscar lashed the island's eastern end.

Cuba's power grid has ground to a halt for a second time in as many days, leaving 10 million on the island without power and the Caribbean island in a growing sense of crisis.

Many of Cuba’s power plants are outdated and inefficient; some have been in operation for over 50 years without proper maintenance.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