On Friday, Cuba's power grid collapsed nationwide, affecting millions of people as the Trump administration increases economic pressure on the Cuban government. This is at least the sixth such collapse this year, with previous outages in March and over the summer. The failure began with a breakdown in high-voltage transmission lines in western Cuba, spreading to other parts of the country due to the interconnectedness of its power system. The United States has intensified sanctions against Cuban entities and officials, including restricting fuel supplies that exacerbate energy shortages on the island.

Story summary
On Friday, Cuba's power grid collapsed, leaving millions of people across the island without electricity. This was at least the sixth major blackout since January, following previous outages in March, July, and August 2023. The Ministry of Energy and Mines announced the outage on its official X account but did not provide a cause beyond initiating service-restoration protocols.
The frequent power failures are linked to the severe economic crisis exacerbated by the U.S.'s energy blockade, which restricts Cuba’s access to necessary fuel and replacement parts for its aging infrastructure. Even when electricity is available, rolling blackouts still occur daily, with some areas going without power for over 30 consecutive hours.
In Havana, only about 5% of users had power restored by late evening, primarily around hospitals and water pumping stations. Residents are struggling to cope with the ongoing shortages in food, water, and electricity, highlighting the dire situation on the island.
