New York City blackout of 1977

The New York City blackout of 1977 was an electricity blackout that affected most of New York City on July 13–14, 1977. The only neighborhoods in the city that were not affected were in southern Queens (including neighborhoods of the Rockaways, which were part of the Long Island Lighting Company system), as well as the Pratt Institute campus in Brooklyn which operated its own historic power generator.

Unlike other blackouts that affected the region, namely the Northeast blackouts of 1965 and 2003, the 1977 blackout was confined to New York City and its immediate surrounding areas. Also, in contrast to the 1965 and 2003 blackouts, the 1977 blackout resulted in citywide looting and other acts of criminal activity, including arson.
