After some areas of Puerto Rico welcomed the New Year in the dark amid a massive failure to the island’s power grid, service has been restored to nearly all impacted customers.

Power was returned to more than three-quarters of Puerto Rico residents on Wednesday morning after a devastating blackout left nearly 80% of the Caribbean Island territory without electricity going into New Year's Eve.

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.
