BOSTON (AP) — Most utility customers in Massachusetts have had their power restored following the weekend snowstorm.

More than 400,000 outages were reported at the height of the storm that left many areas with at least two feet of snow.

As of mid-evening Wednesday, NStar said it had about 500 customers without power, mostly in Marshfield and Plymouth, and expected to finish restoration ahead of its Thursday time estimate.

National Grid was down to about a dozen isolated outages.

Gov. Deval Patrick said Wednesday that he was more satisfied with the response by the utilities than he was on the previous day, while adding that he understood the frustration of residents who are still without power.

State officials have said they will assess the response by the utilities to the storm once the restoration process is complete.
