Jamaica has emerged from a rare islandwide power outage that struck the Caribbean nation overnight on Friday, with Energy Minister Daryl Vaz announcing on Saturday morning that electricity had been restored to all affected customers. The blackout, which began around 9pm local time and left roughly 700,000 customers without power, was described as "unacceptable" by both Vaz and Prime Minister Andrew Holness, who demanded a full report from sole electricity distributor Jamaica Public Service Company (JPS) within 24 hours. The outage has raised concerns about the resilience of Jamaica's electrical grid, coming at the start of the Atlantic hurricane season just months after Category 5 Hurricane Melissa caused widespread destruction and dozens of deaths across the island.
