Cuba is facing prolonged blackouts this week, with power cuts lasting more than 12 hours and an electricity generation deficit approaching 2,000 MW, according to official data. UNE (Electric Union).

Reports released this week indicate that the country's generation capacity remains below national demand, with a significant impact on service during peak consumption hours.

Havana, the capital, suffered power outages, with the Electric Company of Havana reporting up to 17 hours of blackouts, while several thermal power plants remain out of operation due to failures or maintenance.

UNE highlighted that the contribution of renewable sources, such as photovoltaic solar parks, has been insufficient to compensate for the limitations of thermal power plants, maintaining the fragility of the national electricity system.

Cuban authorities and companies have yet to provide a clear timeline for the full restoration of service, while the country's energy sector remains under severe pressure due to fuel shortages and reduced generation capacity.
