Cuba has been plunged into darkness once again after its national electric grid experienced a total collapse late Sunday evening. The state-owned utility provider, Union Electrica de Cuba, confirmed the catastrophic failure through brief updates on social media platforms, though they stopped short of offering specific explanations or a timeline for when power might be restored to the island’s 10 million residents.

This latest incident marks a worrying escalation in the frequency of power outages affecting the nation. Coming on the heels of three similar island-wide blackouts experienced throughout July, the situation highlights the precarious state of Cuba’s aging energy infrastructure. Government officials have frequently pointed to the impact of long-standing US-imposed oil sanctions as a primary driver behind the country's struggle to maintain a reliable and functional power supply.
