The provinces of Santiago de Cuba and Guantánamo were disconnected from the National Electric System (SEN) this Sunday after a high-voltage transmission line was triggered, causing a power outage in both areas.
Union Eléctrica (UNE) informed through its WhatsApp channel that the incident occurred on the Cueto-Renté line and that protocols were activated to restore the connection of both provinces to the national system.
"13:14 || Shot from the Cueto Renté Line, disconnecting the provinces of Gtmo and Stgo de Cuba from the SEN. Restoration protocols are activated," the statement noted.
However, the message was posted at 12:32 p.m., one hour earlier than the time indicated in its content, making it impossible to determine the exact moment of the incident based solely on that information.
On its part, the Electric Company of Santiago de Cuba confirmed through its Telegram channel that the interruption affects the electricity supply in both provinces.
"The Electric Company of Santiago de Cuba informs its customers that due to a fault in the 220 kV Line, the provinces of Santiago de Cuba and Guantánamo are currently without electrical service," the entity stated.
The statements confirm that the incident left the SEN disconnected in both territories and caused a disruption in the electricity supply, although the authorities have not specified the causes of the line trip.
Just two weeks ago, the failure of the 220 kV Nuevitas-Las Tunas transmission line caused another partial disconnection of the National Electric System in eastern Cuba, affecting Las Tunas, Holguín, Granma, Santiago de Cuba, and Guantánamo.
On that occasion, the failure occurred at 12:46 p.m. and the regional connection was restored at 3:17 p.m., although the recovery of the system did not necessarily mean an immediate return of electricity to all homes.
A similar episode occurred in August when another incident disconnected the eastern provinces from the SEN, from Las Tunas to Guantánamo, and caused several thermoelectric units to go offline.
The new interruption occurs on a day of severe electricity deficit.
According to the official report this Sunday, UNE forecasted an impact of 1,760 MW during peak demand hours, with an estimated availability of 1,120 MW against a demand of 2,850 MW, resulting in a generation deficit of 1,730 MW.
At 6:00 a.m., the system had only 990 MW available and recorded a shortfall of 1,323 MW due to capacity deficit.
