De Blasio warns Brooklyn residents about possible massive ConEd outage

Mayor Bill de Blasio warned that parts of southern Brooklyn are on the brink of massive power outages Thursday — as he directed residents to conserve energy “as much as possible” amid the fourth day of a sweltering heat wave.

Con Edison issued the warning Thursday morning that the electrical supply in Bay Ridge, Fort Hamilton, South Park Slope, Greenwood and Sunset Park is currently in danger.

“There is a problem in southern Brooklyn,” Hizzoner said at his daily press briefing. “We’ve got to protect our electricity supply for all New Yorkers.”

De Blasio advised “avoiding using major appliances,” including washers, dryers and microwaves and limiting the use of air conditioners “as much as possible.”

“Everyone please take this warning seriously. Please act on it,” he said. “We will push Con Ed hard to resolve this situation quickly.”

The power issues come as temperatures will hit a sweltering 90+ degrees again Thursday.
