Cuba gets some electricity back after major power outage left millions in the dark

HAVANA — (AP) — Cuba's government on Saturday said that some electricity was restored on the island after one of the country's major power plants failed and left millions without electricity for two days.

Energy Minister Vicente de la O Levy said the country had 500 megawatts in its electrical grid early Saturday, as compared to 3 gigawatts that are normally generated. He posted on X that “several substations in the west now have electricity.”

O Levy also said two thermoelectric power plants are back and two more will resume their operations “in the next few hours.”

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.

Havana's electricity company said in a statement earlier on Saturday that a part of its western system was disconnected “after the exit of one of the plants that was delivering service.” That issue has left some parts of the city in the dark once again.

The streets of Cuba's capital, where 2 million people live, were quiet on Saturday, with few cars driving by after a night that was lit by candles and lamps. The impact of the blackout goes beyond lighting, and services like water supply also depend on electricity to run pumps.

This is considered to be Cuba's worst blackout in two years, after a category 3 hurricane damaged power installations and it took days for the government to fix them. This year the electricity service worsened, with several homes in the dark for hours every day.

In addition to the Antonio Guiteras plant, whose failure on Friday affected the entire national system, Cuba has several others and it wasn’t immediately clear whether or not they remained functional.

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 supply collapse was massive.

The Cuban government has announced emergency measures to slash electricity demand, including suspending classes, shutting down some state-owned workplaces and canceling nonessential services. Officials said that 1.64 gigawatts went offline during peak hours, about half the total demand at the time.

Local authorities said the outage, which started in a smaller scale on Thursday, stemmed from increased demand from small and medium-sized companies and residences’ air conditioners. Later, the blackout got worse due to breakdowns in old thermoelectric plants that haven’t been properly maintained and the lack of fuel to operate some facilities.

Changes to electricity rates for small- and medium-sized companies, which have proliferated since they were first authorized by the communist government in 2021, are also being considered.
