"We are ready to mobilize a small army of line workers, tree professionals, damage assessors and support personnel who will begin work as soon as we safely can", said Luis Ordaz, Duke Energy Florida storm director.
Trees were blocking roadways in several areas of Fort Mill, and Rock Hill officials said about 3,000 people were affected by a power outage at the Charlotte Avenue substation.
Crews will wait to begin their work until wind speeds diminish to the point at which it is safe to operate hundreds of aerial "bucket" trucks and other equipment without endangering workers.
Crews will be working with Duke Florida, Tampa Electric and Florida Power and Light as long as they are needed.
Assistance from across the United States and Canada, including company resources from the Midwest, is on the way to assist with restoration efforts.
Mutual assistance from neighboring utilities is a hallmark of the electric utility industry, and can include not only crews but also other resources and equipment, such as helicopters and drones, high-water vehicles and other specialty equipment, as well as material that can be allocated and shared among electric companies to ensure all restoration and recovery needs are met.
At the same time, the company will safely fix major power transmission lines, damaged substations and other large-scale electrical equipment to restore power to the largest number of customers, as quickly as possible.
By 5 p.m., power was restored to most of those south Charlotte residents, but more than 400 were without power in the Ballantyne area.
A number of community partners - including fire stations, shopping centers and other facilities - have generously offered their parking lots and buildings to Duke Energy to serve as "base camps" to stage fix trucks and other equipment.
