The dawn of the luneThe storm has resumed with widespread blackouts across almost the entire country. Since last night, thousands of homes have been without electricity for more than twelve consecutive hours, while national demand continues to far exceed available capacity.
The reports Union Electrica officials confirm that the system remains in critical condition. The impacts not only persist during the day, but worsen at night, when consumption soars and generating equipment is unable to sustain the load.
According to the official report of October 6, 2025, the availability of the National Electric System (SEN) at six in the morning was 1770 megawatts, compared to a demand of 2730. This caused an initial impact of 975 MW, which could rise to 1200 MW during peak daytime consumption hours.
A new deficit exceeding 1600 MW
The Ministry of Energy and Mines' information release indicates that 24-hour service was affected the previous day, with a peak of 1636 MW at 19:40 p.m. The increased deficit was associated with the emergency shutdown of Unit 3 of the Ernesto Che Guevara Thermoelectric Plant in Santa Cruz del Norte.
In addition to this breakdown, Unit 2 of the Felton CTE, Unit 8 in Mariel, and Units 3, 5, and 6 of the Renté CTE remain out of service. Units 1 and 2 in Santa Cruz and Unit 4 of the Carlos Manuel de Céspedes CTE in Cienfuegos are undergoing maintenance.
Thermal limitations have brought another 272 MW out of service, while 44 distributed generation plants, totaling 297 MW, remain shut down due to fuel shortages, along with another 227 MW halted due to a lack of lubricants. In total, 524 MW are unavailable due to this cause.
Solar production insufficient to meet demand
Although the country has 32 new photovoltaic solar parks, their contribution is still insufficient to cover consumption. According to the Electricity Union (Unión Eléctrica), these parks generated 3145 MWh on Sunday, with a peak power of 497 MW at midday.
Renewable energy provides temporary relief, but it fails to offset the deficit caused by the instability of thermal power plants and fuel shortages. Experts have warned that the dependence on diesel and the lack of structural maintenance keep the SEN in a fragile situation.
Peak Hour Outlook
For peak demand times, the estimated recupgeneration of only 50 MW in distributed motors. With this contribution, total availability would reach 1820 MW, compared to an expected maximum demand of 3350 MW. The deficit would be 1530 MW, which would imply impacts of up to 1600 MW during the night.
The trend confirms that the country still has no room to maneuver to reduce blackouts. Meanwhile, the population faces long days without electricity and a system that is increasingly dependent on external conditions, both technical and energy-related.
