Power outage in Puerto Rico: Crews scramble to restore power after island-wide outage

The outage is believed to be linked to a problem at the Costa Sur power plant outside the town of Guayanilla near the island’s southwest coast, Puerto Rican utility company LUMA Energy said.

A fire was visible at the factory in video posted Wednesday night to social media by the Puerto Rico Electric Power Authority.
LUMA Energy is working to restore power to customers, and the exact cause and number of people affected were not immediately known, the utility noted early Thursday on Twitter.

“The power grid suffered a massive island-wide power outage, potentially caused by a circuit breaker failure at the Costa Sur generating station,” LUMA officials said Wednesday. In that statement, the company said it expects restoration efforts to continue through Thursday.

Firefighters extinguished flames that hit two substations at the Costa Sur plant, the Puerto Rico Fire Bureau announced on Facebook on Wednesday. The cause of the fire was not immediately known, firefighters said.

LUMA is a joint venture of Quanta Services and Canadian energy company ATCO, which the Puerto Rican government has chosen to take over the operation of the electricity grid from its former electric utility, PREPA. LUMA has been in charge of the electricity network since June 1.
