Since late 2024, the National Electric System has suffered several nationwide blackouts.
On Tuesday, the Havana Electric Company reported that at 11:05 a.m., another total blackout occurred in the National Electric System (SEN), the third one in the last eight days.

The company explained that a shutdown of the Felton 1 unit caused a fluctuation in the system parameters with a sudden frequency change, which led to the SEN outage. Work is currently underway to restore power to the thermoelectric plants in western Cuba.
The SEN is preparing plans for the creation of microsystems, which will allow for the restoration of power to vital centers once the necessary technical conditions are met, as part of the recovery process.
This latest interruption comes amid growing economic pressure on Cuba, marked by energy sanctions imposed by the United States.

The text reads, “The new disconnection of the National Electric System is a direct consequence of the energy siege and the extreme tightening of the U.S. blockade against Cuba. It is part of the collective punishment of the Cuban people on which the U.S. government is betting to destroy the Cuban Revolution.”
Washington is blocking oil shipments to the island following an executive order signed in January by President Donald Trump, which threatens tariffs on countries that export or facilitate the supply of fuel to Cuba.
Since late 2024, the National Electric System (SEN) has suffered several nationwide blackouts amidst the effects of the more than six-decade-long economic blockade, which limits access to resources for the maintenance and development of the electricity sector.
Restoring the SEN is a slow and laborious process: it begins with simpler starting sources such as solar, hydroelectric, and generating engines, followed by interconnecting small areas and bringing power to the thermoelectric plants, the backbone of national generation.
