Cuba woke up this Sunday engulfed in a new day of widespread blackouts.
According to the official information note from Unión Eléctrica (UNE), at 6:00 am the availability of the National Electric System (SEN) was only 1,070 MW compared to a demand of 2,545 MW, leaving 1,457 MW without supply.
The outlook for peak hours is even more bleak.
The UNE forecasts an availability of only 1,147 MW against a peak demand of 3,200 MW, resulting in a deficit of 2,053 MW and an estimated impact of 2,083 MW during peak consumption hours.
On Saturday, the situation was already devastating. The maximum impact reached 2,041 MW at 9:10 PM, surpassing the previous forecast due to the non-entry of unit two from the Santa Cruz Thermoelectric Power Plant (CTE) and the limitation of unit four from the Cienfuegos Thermoelectric Power Plant.
The capital did not escape the collapse.
The Electric Company of Havana reported that on Saturday the electrical service was interrupted in Havana for 24 hours. The highest impact was 447 MW at 9:10 PM.
The entity also admitted that "it was necessary to shut down circuits due to an emergency with 110 MW" and that "it was not possible to restore the service," with six blocks and emergency circuits -322 MW- still affected at the time of closing their statement.
The breakdown report that the system is facing is alarming.
Five units from the CTE Ernesto Guevara De La Serna, Antonio Guiteras, Lidio Ramón Pérez, and Antonio Maceo are out of service. Additionally, there are three units under maintenance and 423 MW further out of service due to limitations in thermal generation.
The 54 installed photovoltaic parks contributed 3,963 MWh on Saturday, peaking at 616 MW at noon, a figure that fades by nightfall due to the lack of large-scale storage batteries. The solar energy is insufficient to cover blackouts while the thermoelectric plant continues to deteriorate.
This crisis is not an isolated episode, but rather the most recent expression of a structural collapse that the regime has been unable to halt.
On May 13, a record deficit of 2,153 MW was registered, and the next day the shutdown of the CTE Antonio Guiteras -its ninth malfunction in 2026- caused a partial collapse of the SEN from Ciego de Ávila to Guantánamo.
The Minister of Energy and Mines, Vicente de la O Levy, himself admitted that Cuba has "absolutely no fuel, no diesel, only accompanying gas".
A Russian donation of 100,000 tons of crude oil, processed at the Cienfuegos refinery, was exhausted in early May without the regime securing an alternative supply.
The government's bet on solar energy does not address the fundamental problem.
Under social pressure, Prime Minister Manuel Marrero limited himself to ordering to "better distribute" the blackouts in Havana, a response that reveals the government's inability to provide real solutions.
Meanwhile, in provinces such as Holguín, Granma, Santiago de Cuba, and Guantánamo, outages exceed twenty hours a day, and Cubans have taken to the streets to protest with kitchenware against a regime that prefers to blame the U.S. embargo rather than take responsibility for seven decades of disastrous management.
The CTE Antonio Guiteras, the largest individual power generator in the country, could resume operations on May 19, although its structural condition is precarious: the plant has not received major maintenance since 2010, making any recovery forecast a fragile promise.
