The National Electric System (SEN) is experiencing another critical day this Sunday, June 22, following a reported electricity generation deficit of 1,880 MW the day before, according to data shared on social media by the Electric Union (UNE).
The value, recorded at 9:00 PM, becomes the second largest blackout in the recent energy history of the country and exceeded the forecast by 110 MW made by the state-owned company under the control of the Cuban regime.
UNE itself acknowledged that the impact exceeded what was planned due to a demand higher than forecasted and the unexpected outage of unit 1 at the CTE Santa Cruz, which left the country in a critical situation during the 24 hours of Saturday and into the early hours of this Sunday.
At 07:00 hours today, the availability was only 1,820 MW, while the demand reached 2,958 MW, creating a deficit of 1,138 MW. By noon, a shortfall of 1,150 MW is expected.
At night peak, with a projected demand of 3,500 MW and no new units expected to come online, an impact of up to 1,750 MW is anticipated, which places the country once again on the brink of an energy collapse.
Official data reports 837 MW lost solely in distributed generation, with 93 power plants out of service due to lack of fuel and an additional 92 MW due to a shortage of oil in engines. Furthermore, there are five thermal units unavailable due to maintenance or breakdowns, including Mariel, Felton, Santa Cruz, Cienfuegos, and Renté.
Although 1,808 MWh were reported as generated by 16 solar parks, this contribution remains symbolic in the face of the structural deficit.
The official journalist José Miguel Solís shared on Facebook a historical analysis where the blackout on Saturday stands as the second largest of all time, surpassed only by the 1,901 MW on April 23rd.
Of the 12 largest deficits reported in recent history, five occurred in April 2025 and three in June, confirming a growing pattern of systematic collapse.
Numerous Cubans are reporting that the figures from the UNE are inaccurate, manipulated, or even fictional, used to conceal the true extent of the energy disaster. Distrust is heightened by the lack of real solutions and the feeling that the blackout is more severe than what the daily reports indicate.
Meanwhile, life on the island dims amid candles, impotence, and anger. Cuba sinks into an increasingly prolonged and dangerous darkness, with no visible horizon.
