NEW YORK — Frustrated Long Island residents have staged a protest against the Long Island Power Authority even as utilities made progress in restoring power to customers whose lights went out during Superstorm Sandy and Wednesday’s nor’easter.

LIPA says nearly 140,000 homes and businesses still didn’t have power by mid-afternoon Saturday.

Hundreds of people demonstrated in front of LIPA’s Hicksville office Saturday to protest what they call unacceptable delays. The utility didn’t return a request for comment.

Meanwhile, Con Edison says it will restore power this weekend to all its New York City and Westchester County customers whose buildings are in good enough shape to turn electricity back on. About 11,400 of them remained without power Saturday evening.

Those figures don’t include about 30,000 homes and businesses too damaged to juice up.
