Some neighbourhoods had electricity restored in Cuba’s capital Havana, where two million people live, but most of the island remained dark. The impact of the blackout goes beyond lighting, because services like water supply also depend on electricity to run pumps.
People resorted to cooking with improvised wood stoves on the streets before the food went bad in refrigerators.
In tears, Ylenis de la Caridad Napoles, mother of a seven-year-old girl, said she was reaching a point of “desperation”.
The failure of the Antonio Guiteras plant on Friday, which caused the collapse of the island’s whole system, was just the latest in a series of problems with energy distribution in a country where electricity has been restricted and rotated to different regions at different times of the day.
People lined up for hours yesterday morning to buy bread in the few bakeries that could reopen.
Some Cubans such as Rosa Rodriguez have been without electricity for four days.
“We have millions of problems, and none of them are solved,” Ms Rodriguez said. “We must come to get bread, because the local bakery is closed, and they bring it from somewhere else.”
About half of Cuba was plunged into darkness on Thursday evening, followed by the entire island on Friday morning after one of the plants failed.
Besides the Antonio Guiteras plant, whose failure on Friday affected the entire national system, Cuba has several others, and it wasn’t immediately clear whether they remained functional.
The blackout was considered to be Cuba’s worst in two years after Hurricane Ian made landfall as a Category 3 storm in 2022 and damaged power installations. It took days for the government to fix them. This year, some homes have spent up to eight hours a day without electricity.
Cuba’s government said on Saturday that some electricity had been restored after one of the country’s major power plants failed. But the 500 megawatts of energy in the island’s electricity grid, far short of the usual three gigawatts it needs, had quickly decreased to 370 megawatts.
There is no official estimate for when the blackout will end. Even in a country that is used to outages as part of a deepening economic crisis, Friday’s collapse was massive.
The Cuban government has announced emergency measures to slash electricity demand, including suspending school and university classes, shutting down some state-owned workplaces and cancelling non-essential services.
Local authorities said the outage stemmed from increased demand from small and medium-sized companies and residential air conditioners. Later, the blackout got worse because of breakdowns in old thermoelectric plants that haven’t been properly maintained, and the lack of fuel to operate some facilities.
