Havana - Cuba 's state-run Unión Eléctrica (UNE) expects new blackouts this Sunday due to an energy deficit of 31% of the generation capacity during peak demand hours.
The estimate for the peak hour (first hour of the night) is an availability of 2,181 megawatts (MW) and a maximum demand of 2,850 MW, which means a deficit of 679 MW.
Consequently, UNE foresees a maximum demand of 749 MW at that time, plus 145 MW related to the damages caused by the passage of hurricane Ian through the western end of the country last Tuesday.
UNE's daily report details that 9 units of various thermoelectric plants in the country - among them, the Antonio Guiteras, one of the largest - are currently out of service due to breakdowns. Another block is under maintenance.
Saturday was marked by a generation capacity deficit during the whole day and the maximum impact on the service (806 MW) was registered during peak consumption hours.
Power outages - due to breakages and failures in thermoelectric plants, lack of fuel and scheduled maintenance - have been common for several months in the country.
Between July and September there have only been two days without power cuts, according to UNE data collated by Efe.
The Cuban government announced in September that it seeks to reduce blackouts before the end of this year through repairs and new investments.
The blackouts affect all areas of the economy and notably the daily life of Cubans, which is fueling social discontent in a country undergoing a severe crisis.
These were one of the main reasons behind the anti-government protests of July 11 last year, the largest in decades.
In the last three days there have been protests for this cause in several neighborhoods of Havana, and in the provinces of Camagüey (center) and eastern Holguín.
The most recent one took place this Saturday in an area of the Havana neighborhood of Vedado, where more than a hundred people demonstrated to demand electricity, when a large part of the capital city has recovered it after the general blackout caused by Hurricane Ian.
This is the third night in which pot-banging, traffic blockades and sit-ins to demand electricity have been reported, mainly in poor neighborhoods of Havana.
