How did Puerto Rico’s electric system become so chaotic? Experts weigh in

Puerto Rico’s electric system is worst in the US, experts say. How did it turn so chaotic?

"Luma out" and "If I can't breathe, Luma shouldn't charge us," read some of the banners held by hundreds of Puerto Rico's residents as they marched on a main highway Friday in protest against Luma Energy, the island's power company.

Puerto Rico has had a long history of instability with its electric system, even prior to the devastation Hurricane Maria wreaked in 2017, which left millions on the island without power for nearly a year.

Still, blackout and brownouts are a part of daily life for Puerto Rico's citizens, with a recent power outage now affecting thousands.
