A massive power outage plunged nearly all of Puerto Rico into darkness on New Year's Eve, leaving millions without electricity.
The cause remains under investigation, but initial reports suggest a fault in an underground power line caused the widespread blackout.
Authorities estimate that full power restoration could take up to two days, impacting the island's economy and daily life.
This latest outage has reignited calls for significant improvements to Puerto Rico's unreliable and aging power grid infrastructure.
