The blackouts continue to dominate the day in Cuba, even after the commissioning of the Antonio Guiteras Thermoelectric Power Plant (CTE), one of the main plants in the country. Just hours after its synchronization, the electrical system was once again affected by the shutdown of another generating unit in the eastern part of the island.
According to reported by Unión Eléctrica (UNE), the CTE Antonio Guiteras, located in Matanzas, is a key addition to alleviate the generation deficit at 1:29 PM.
However, at 5:16 PM, the entity itself reported the outage of Unit 6 of the Antonio Maceo “Renté” power plant in Santiago de Cuba, due to low pressure in the output transformer bushings.
The alternation between plant inputs and outputs maintains the instability of the National Electric System, failing to provide any real relief for the population, which continues to face prolonged and rotating blackouts across almost the entire country.
As part of the daily report from UNE, the forecast for the peak hours on December 29, 2025 reflects the magnitude of the problem:
Availability: 1.488 MW
Maximum demand: 3,250 MW
Deficit: 1,762 MW
Estimated impact: 1,792 MW
The figures confirm that, despite the reactivation of the Guiteras, the system is still far from meeting the national demand, which translates into long hours without electricity for millions of Cubans.
While the commissioning of large thermal power plants is often seen as a sign of relief, the almost immediate decommissioning of other units highlights the structural problems in the electricity sector, marked by technological decay, lack of maintenance, and chronic shortages of fuel and parts.
Meanwhile, power outages continue to impact daily life, food preservation, and the provision of basic services, with no sustainable solution in sight in the short term.
