SAVANNAH, Ga. (AP) - Georgia Power says it's sending extra crews to Savannah to speed up a $51 million upgrade of the downtown electrical grid after an underground fire and explosion last week was linked to aging power cables.
The Dec. 29 explosion is the second underground blast to rattle downtown businesses since August. Nobody was hurt in either blast.
Georgia Power spokesman Jeff Wilson says electrical cables beneath Savannah's streets are 50 to 80 years old. The utility began work two years ago to upgrade the system.
Georgia Power said Tuesday it will double its efforts starting this month to get the work finished by 2012 - four years ahead of schedule.
