Cuba's electrical system has collapsed after the country's largest power plant failed, the government says, the latest of several such failures as the island's grid falls into disarray amid fuel shortages, natural disaster and economic crisis.
The country's energy and mines ministry said the Antonio Guiteras power plant in Matanzas, the island's top electricity producer, had shut down about 2am, prompting the grid collapse.
Cuba's oil-fired power plants, already obsolete and struggling to keep the lights on, reached a full crisis this year as oil imports from Venezuela, Russia and Mexico dwindled, contributing to multiple country-wide blackouts over two months.
The system failure on Wednesday morning had left the capital Havana almost completely in the dark, according to a Reuters witness.
Lights before sunrise could be seen only in a handful of large hotels and government buildings across the city's skyline.
Reports of blackouts elsewhere in Cuba on social media suggested the entire island of about 10 million people was without power although the government had yet to confirm the extent of the outage.
The energy and mines ministry said it was working to reconnect the electrical system.
Cuba's grid collapsed multiple times in October as fuel supplies dwindled and Hurricane Oscar struck the far-eastern end of the island, then again in November with the passage of Hurricane Rafael.
