The outage plunged the country, including the capital Havana, into darkness, marking the sixth such grid collapse this year. Residents face significant disruption to daily life, with power cuts impacting water supplies and basic amenities. The country has been experiencing rolling blackouts due to a combination of aging infrastructure and a U.S. energy embargo that has restricted fuel deliveries. The Ministry of Energy has stated that efforts to reactivate the grid are in progress.
