Cuba experienced its second nationwide blackout in less than a week on Saturday, plunging the island into darkness due to a failure in its national power network.

• The blackout was caused by an outage in a power unit at a thermoelectric plant, leading to a "cascading effect" across the grid.
• This crisis is exacerbated by aging infrastructure, a US oil blockade, and the absence of oil imports since January 9.
• Residents like Ofelia Oliva described the situation as "unbearable" and "tiresome," highlighting the daily difficulties faced by Cubans, including up to 15-hour outages in Havana.
