Puerto Rico's Power Outage Enters Second Night

Vehicle lights illuminate a street after a massive blackout, in San Juan, Puerto Rico, Sept. 22, 2016. Puerto Ricans faced another night of darkness Thursday as crews slowly restored electricity a day after a fire at a power plant caused the aging utility grid to fail and blacked out the entire island.

The Electric Power Authority said investigators were trying to determine what caused the fire that broke out Wednesday afternoon. The blaze began at a switch and caused two transmission lines of 230,000 volts each to fail.

The outage was the latest hit for an island mired in a decade-long economic crisis and whose government has warned it is running out of money as it seeks to restructure nearly $70 billion in public debt.

Many Puerto Ricans expressed doubts that power would be restored quickly, saying the economic slump has affected basic government services. Hundreds of people took to social media to criticize the Electric Power Authority, noting that they already pay bills on average twice that of the U.S. mainland.
