Connecticut Light & Power says it is getting about 200 additional line workers and 250 more tree cutters, who will be in the field as early as Thursday. That brings their totals to about 1,800 line workers and 1,200 tree workers.
United Illuminating also is adding crews from as far away as Nova Scotia, and hopes to have increased the number of workers in the field from 850 to 1,000 in the next day.
Both companies say they will provide estimates Thursday as to when they expect to fully restore power in Connecticut.
About 378,000 utility customers remained without power Wednesday evening.
