An Automatic Frequency Shot (DAF) left several municipalities in Havana without electricity this Wednesday, according to the Electric Company of the capital, as reported through its official Telegram channel.
"We would like to inform the customers in the Capital that due to Automatic Frequency Discharge (DAF), the electric service in several municipalities is being affected," emphasized the brief statement.
For this Wednesday, the Electric Union (UNE) had predicted a deficit of 1,100 MW during peak demand hours.
According to the report, at 6:00 AM, the National Electric System (SEN) already registered 266 MW affected, with a demand of 2,136 MW and an availability of 1,980 MW. By noon, the UNE estimated outages of 750 MW.
The only improvement expected for the night peak is the entry of unit four of the Carlos Manuel de Céspedes thermoelectric plant (CTE) with 150 MW, which is currently in the startup process.
However, only 2,130 MW was anticipated to be available against a demand of 3,200 MW, resulting in a deficit of 1,070 MW.
Five thermoelectric units remain out of service this Wednesday at the CTE Ernesto Guevara De La Serna, Diez de Octubre, Carlos Manuel de Céspedes, Antonio Maceo, and Felton.
In addition, three units are undergoing maintenance at the CTE Mariel, Renté, and Nuevitas, not including 381 MW of additional thermal limitations out of service.
This new power outage occurs a week after Abel Fernández Díaz, director of the Aqueduct of Aguas de La Habana, reported that over 200,000 residents of Havana —about 11% of the capital's population— were without regular access to drinking water as a direct consequence of the power outages affecting Cuba.
Moreover, the Electric Company of Havana informed at the beginning of the month that an Automatic Frequency Trip (DAF) left several municipalities in the Cuban capital without electrical service, adding a new episode to the series of failures affecting the city in 2026.
