Power outages are a frustratingly frequent occurrence for many Puerto Ricans. A string of blackouts during the summer prompted protests and a state of emergency.

Puerto Rico remained mostly without power Tuesday after a massive outage swept the island. Leaders said the electric system was failing its residents.

The massive blackout may leave much of the island without electricity as 2025 begins. A “massive blackout” that hit much of Puerto Rico early Tuesday may keep the U.S. territory in the dark through New Year’s Eve and beyond, according to the governor and the private energy company that provides power to the island.
