As of 3:45 p.m. Tuesday, 1,438 Westborough customers remained without power because of Hurricane Sandy, according to National Grid's website.
National Grid serves 7,849 customers in Westborough.
The utility is now completing assessments of the affected areas. Once those assessments are finished—a process expected to be completed early Wednesday morning—individual outages will be assigned specific time frames for restoration. Restoration estimates could come tonight.
In a conference call, Marcy Reed, president of National Grid in Massachusetts, told the media that until the assessments are completed, she couldn't say how long it will take for power to be completely restored. Once the assessments are done, the utility will share the information through media and on its website.
Priority for power restoration went to public safety complexes and hospitals. Overnight, National Grid restored power to eight hospitals in the state that lost power, she said.
National Grid has 2,400 people working in Massachusetts to restore power Tuesday, and good weather has allowed crews to make progress, the utility reported in the conference call.
The crews are working 16 hours on - eight hours off and will continue until all customers are restored.
At its peak, Hurricane Sandy power losses totaled 237,000 customers in Massachusetts. The number as of 3 p.m. without power: 163,000.
