Massive power outage in Puerto Rico affects hundreds of thousands amid growing outrage

A sudden power failure left more than 330,000 clients in the dark across Puerto Rico late Wednesday, enraging many who were recovering from a massive outage that hit the U.S. territory just days ago.

Luma Energy, a private company that took over the island's power transmission and distribution system on June 1, said three units were knocked offline for reasons not immediately known. At first, the company said some 190,000 clients had been affected, but it later tweeted that power had been restored to more than 180,000 clients and that another 156,700 were still without electricity. Various spokeswomen did not return calls for comment.
