Blackouts in Cuba: seven thermoelectric units out of circulation

MIAMI, United States. — The numerous breakdowns of several of the main thermoelectric plants in the country will continue to cause massive blackouts throughout the national territory, the Cuban Electric Union (UNE) reported on Wednesday.

The company stated in social networks that units 6 and 7 of the Máximo Gómez thermoelectric power plant (CTE) (Artemisa/Mariel), unit 3 of the Ernesto Guevara CTE (Mayabeque), unit 4 of the Diez de Octubre CTE ( Havana) and units 3, 4 and 5 of the CTE Antonio Maceo (Santiago de Cuba).

According to the note, only for units out of service will they stop generating up to 650 megawatts (MW). The generation deficit will peak at midday.

A unit of the CTE Otto Parellada (Havana), units 1 and 2 of the CTE Lidio Ramón Pérez (Holguín) and unit 6 of the CTE Antonio Maceo also receive maintenance. The repairs in those units will cause limitations in the thermal generation of 333 MW.


This Monday there were blackouts throughout the country “due to a lack of generation capacity.” The interruptions began in the morning hours and lasted until early today, a situation that is expected to continue in the coming hours.

The information from the UNE specifies that the maximum impact during peak hours was 453 MW at 9:00 p.m.

In distributed generation (energy sources not associated with thermal generation) 1,067 MW are unavailable due to breakdown and 400 MW are undergoing maintenance.

To make up for the generation deficit during peak hours, the Electric Union assured that 118 MW from diesel engines will be used.

The UNE indicates that for the peak hours of this Tuesday “an availability of 2,188 MW and a maximum demand of 2,750 MW is forecast, for a deficit of 562 MW, for which affectations to the service are forecast at this time.”

The company also announced that “all measures to restrict consumption in the state sector are implemented.”
