In Puerto Rico, nearly half a million people remain without electricity after a fire at a main power plant caused the biggest blackout the island has seen so far this year. Thursday’s massive outage also left some 168,000 residents without water. The latest blackout has intensified public outrage against LUMA Energy, the private Canadian-American company that took over transmission and distribution of power from Puerto Rico’s public utility last June — a move that was imposed by the United States. LUMA has so far failed to reduce the frequency of power outages that have impacted Puerto Ricans in the aftermath of 2017’s Hurricane Maria, which decimated the island’s electric grid.
