Outside thermoelectric generation units and lack of fuel are the causes for the high prognosis of this July 27.
Arequipa, Peru – The Electric Union (UNE) of Cuba confirmed that the electricity service was interrupted throughout this July 26 and that this Sunday there would also be generalized effects in more than 40% of the island.
The situation of the National Electrical System (SEN) continues serious. For this July 27, almost half of the island will be in a blackout due to a deficit of 1,370 megawatts (MW).
Currently several units of Thermoelectric generation They are out of service due to breakdowns or maintenance. They are also not working due to lack of fuel 87 distributed generation plants with 749 MW and five engines in the rule pin with 40 MW, for a total of 789 MW affected by this cause.
“In the peak schedule, an availability of 2,095 MW and a maximum demand of 3,700 MW is estimated, for a deficit of 1,605 MW, so if the planned conditions are maintained, an affectation of 1,675 MW is forecast at this time,” says the part of the UNE For this Sunday.
In areas of the interior of the country, the cuts can exceed 20 hours a day, forcing many families to cook with firewood, improvise cooling systems, and completely reorganize their routines.
Older people, young children and patients with chronic diseases, are the most vulnerable sectors in this situation; which in turn aggravates food insecurity and limits access to drinking water and basic health services.
The energy crisis that Cuba lives is not new, but has climbed more intensity since 2021, when the mass blackouts began after the collapse of several generating units. To this are added the chronic lack of currency, inefficiency in state management, imported fuel dependence and the technical deterioration of an obsolete system.
So far from 2025, at least four national blackouts have been recorded that have left Cuba completely in the dark for several hours. Meanwhile, the regime maintains censorship about official protests and misinformation, without allowing free access to technical data or independent means.
On June 28, more than half of Cuba was in a blackout due to a 1907 megawatts deficit (MW), the greatest affectation that has been recorded in the midst of the energy crisis (not including simultaneous collapses throughout the island).
