Cuba is still engulfed in darkness following a complete shutdown of the National Electric System (SEN) that occurred this Monday. Authorities have admitted that they have yet to pinpoint the cause of the system's collapse.

Lázaro Guerra Hernández, the Director General of Electricity at the Ministry of Energy and Mines, stated that the reasons behind the widespread blackout remain unknown, as reported by official media outlets.

The official mentioned that no malfunctions were reported in the generating units that were in operation when the system failure occurred, further deepening the mystery surrounding the origin of the outage that left a substantial portion of the nation without power.

As investigations continue, energy authorities have begun efforts to gradually restore service. According to the latest updates, Energás has managed to bring one of its units back online, while work is underway to supply electricity to the Nuevitas thermoelectric plant in Camagüey and the Carlos Manuel de Céspedes power station in Cienfuegos, aiming to aid the system's restart process.

The government also announced the creation of micro-electric systems in various provinces, a strategy previously employed during national blackouts to gradually restore power supply.

At present, the declared priority is to ensure power is provided to vital centers, while the rest of the country continues to wait for service to be restored.

The total blackout followed a day already plagued by severe electrical interruptions across the nation. According to official data from the Electric Union, the system had been operating with a significant generation deficit, with availability falling far short of actual demand.

Cuba's ongoing energy crisis, characterized by aging thermoelectric plants, fuel shortages, and frequent breakdowns, has resulted in daily blackouts throughout much of the Island. However, the complete disconnection of the SEN has escalated the situation to a more critical level, leaving the country entirely in the dark.

Meanwhile, millions of Cubans are anxiously awaiting the restoration of the electric system, as authorities have yet to provide a clear explanation for one of the most severe blackouts in recent times.
