SCITUATE, Mass. (AP) — More than 100,000 residents in Massachusetts remain without power after a fierce weekend blizzard, and one utility is being criticized for leaving customers in the dark about when their power might come back.

U.S. Rep. William Keating, who represents Cape Cod and the South Shore, said Monday his constituents are frustrated with what they see as a lack of communication from NStar.

Keating claims the utility has failed to share information about its timetable for restoring power.

A message left with a spokesman for the utility was not immediately returned, but earlier Monday, NStar’s president defended the company’s response to the storm.

Boston and several other school districts have announced they will keep schools closed on Tuesday as storm cleanup continues.
