“Guantanamo province has no potential due to the disconnection of the 110 MW line from San Luis, in the province of Santiago de Cuba,” the state-owned company indicated.
Hours later, the entity reported that the connection of the San Luis-Guantánamo line had been restored and that the province was once again connected to the National Electrical System (SEN).
“The hospital circuits are in service. Circuit 301, city center,” the Electric Company stated, explaining that the supply would be restored to other circuits “depending on the availability of the National Interconnected System (SEN).”
However, the restoration announced by the authorities did not mean the immediate return of electricity for all residents.
In the comments section of the post, residents of the city indicated that they were still without electricity in both southern and northern areas of Guantánamo.
The incident once again highlights the fragility of the electrical infrastructure in eastern Cuba, where massive power outages have become a recurring problem.
Guantanamo is plunged into darkness once again
This is not the first time Guantanamo has suffered an interruption of this magnitude.
In December 2025, the province was once again disconnected from the SEN after several 110 kV lines tripped, as confirmed at the time by the Guantánamo Electric Company.
On that occasion, the blackout occurred amid a wave of power outages that affected a large part of the island and worsened during the last weeks of 2025.
The problems were not limited to Guantánamo either. In February 2026, Holguín, Granma, Santiago de Cuba, and Guantánamo were disconnected from the National Electric System (SEN) due to a breakdown at a 220 kV substation in Holguín, which also caused several generating units to go offline.
The recurrence of these episodes reflects the vulnerability of a system that depends on deteriorating infrastructure and insufficient generation capacity.
An energy crisis that the regime is unable to resolve
The blackouts are a consequence of an energy crisis that has deepened for years under the administration of the Cuban regime.
The lack of maintenance and sufficient investment, the recurring breakdowns of thermoelectric plants, the shortage of fuel and the inability to guarantee stable generation have made power outages a part of the daily life of Cubans.
At the end of 2025, for example, several thermoelectric units remained out of service due to breakdowns or maintenance, while the Electric Union reported deficits of close to 2,000 MW during peak demand hours.
The result is that even when authorities announce the reconnection of a province to the National Electric System (SEN), as happened this Monday in Guantánamo, thousands of people may continue without electricity due to insufficient generation capacity. @ADNCuba
