The Electric Company of Havana warned that if the conditions for the availability of the National Electric System (SEN) do not improve, “blocks and circuits are expected to be affected by Energy Contingency without a scheduled time,” a measure that would be implemented in response to the generation deficit and the instability of the system.

The alert was issued in the context of a preceding day with disruptions lasting 24 hours across the country and a forecast of a high deficit during peak hours.

According to the Informative Note from the SEN this Saturday, January 31, 2026, on the day prior, the maximum disruption due to generation capacity deficit reached 1916 MW at 18:20.

By the morning of the 31st, the availability at 06:00 was 1160 MW against a demand of 1995 MW, affecting 830 MW, and it was estimated that by noon there would be an impact of 1150 MW.

The report lists the main incidents as breakdowns in several thermoelectric units: Unit 5 of the Mariel CTE, Unit 5 of Nuevitas, Unit 2 of the Felton CTE, and Units 3 and 6 of the Antonio Maceo CTE.

Additionally, maintenance work is reported at Unit 3 of the Santa Cruz Thermoelectric Plant, Unit 4 of the Carlos Manuel de Céspedes Thermoelectric Plant (Cienfuegos), and the Antonio Guiteras Thermoelectric Plant.

There are limitations in thermal generation: 366 MW out of service.

Additionally, it was reported that on the morning of the 31st, Unit 2 of the CTE Ernesto Guevara de la Serna was offline due to a failure in the turbine regulation system.

Forecast for peak hours

The report estimates a peak demand of 3040 MW and an availability of 1160 MW, which would leave a deficit of 1880 MW; if these conditions persist, a impact of 1910 MW during that time is forecasted.

The Electric Company of Havana reported that the service in the capital was disrupted the previous day starting at 5:45 PM. It indicated that the “maximum sufficiency” was 380 MW at 6:20 PM, and that due to “EMERGENCY,” the disruption was 80 MW.

He also pointed out that it was possible to restore the service for deficit at 11:25 PM, and that at the time of closing the report there was no deficit impact, although he made it clear that the situation could change if the availability of the SEN did not increase.

The company asked customers to stay informed through its official channels and accounts or by calling 18888 (Customer Service Center), in a context where the impacts may vary and, should availability worsen, unexpected outages may occur due to contingencies.

From Santiago de Cuba, electricity authorities describe a crisis characterized by breakdowns and maintenance, with rotation for four blocks and reduced service in ranges of 3 to 6 hours depending on the available load, in addition to warnings about lower photovoltaic support if weather conditions worsen.
