Video shows what appears to be a transformer exploding at the Con Ed power plant in Lower Manhattan after Hurricane Sandy made landfall on Monday night.
The first video was shot from a building rooftop in the Navy Yard.
The second video, shot from across the East River, shows a powerful explosion from the Con Ed power plant and a bright flash of blue flame lighting up the night sky.
According to MSN Now, the whole of Lower Manhattan was plunged into darkness after the explosion on Monday night.
Ninemsn reports that a Brooklyn resident said she saw several powerful blue flashes and then a "whooshing" sound. She said: "My heart dropped into my stomach and for a few seconds I thought we were all going to die. Then I doubted what I saw because it seemed too crazy."

The sea surged to nearly four meters at the foot of Manhattan, Ninemsn reports, and water levels are now at record highs in the city. The New York headquarters of the Fire Department was evacuated by boat.
Thirteen people have been reported killed in New Jersey, New York, West Virginia, Pennsylvania and Connecticut. Five of the deaths were reported in New York. According to the Daily Mail, some of the victims were killed by falling trees.
