Cuba Plunged Into Darkness After National Power Grid Collapses

Cuba suffered another nationwide blackout after its national electricity grid collapsed, leaving millions without power across the island. The latest outage underscores the country's deepening energy crisis, driven by aging infrastructure and severe fuel shortages.

Cuba's national electricity grid collapsed late Sunday, triggering a nationwide blackout that left the island's roughly 10 million residents without power, according to the state-run Electric Union (UNE). Authorities did not immediately identify the cause of the failure or provide a timeline for restoring electricity, though officials began the standard process of rebuilding isolated sections of the grid to supply critical facilities such as hospitals, water systems and food production before reconnecting the wider network.

The outage followed three nationwide blackouts in July and came after days of localized power cuts caused by equipment failures, damaged transformers and insufficient generating capacity. Cuba's electrical system has deteriorated in recent years as aging thermoelectric plants, many decades old, have struggled with repeated breakdowns and a lack of maintenance. The country has also faced chronic fuel shortages, reducing electricity generation and leading to rolling blackouts that have become part of daily life for many residents.

Cuban officials have attributed the worsening energy crisis to U.S. sanctions and restrictions that have disrupted fuel imports and access to financing and replacement parts, while critics also point to years of underinvestment in the power sector. In recent weeks, the government has introduced measures to open parts of the state-controlled energy market to private participation in an effort to improve fuel distribution, but the latest nationwide collapse highlights the continuing vulnerability of the country's electricity system as it confronts mounting economic pressures.
