Islandwide blackout hits Puerto Rico nearly seven months after Hurricane Maria

An island-wide blackout hit Puerto Rico on Wednesday, knocking out power throughout the island seven months after Hurricane Maria destroyed its electrical grid. Geraldo Quiñones López, a spokesman for the Puerto Rico Electric Power Authority, told NBC News early Wednesday afternoon that there was "zero percent" power generation on the island. "The breakdown affected the entire electrical system and generating plants," he said.
