Less than 2% of the more than 1.8 million Dominion Virginia Power (Richmond, Virginia, U.S.) customers affected systemwide by Hurricane Isabel remained without power Tuesday, and the company is on target to have service restored to all customers by Friday.

As of 3 p.m. Tuesday, the company had restored power to more than 1.7 million customers; about 31,000 customers remain without power. Much of the work is focused on the Newport News-Suffolk, Northern Neck-Gloucester and Richmond Metro/Tri-Cities areas.

As the number of restored customers increases and the work is concentrated in smaller geographic areas, some of the line crews that came to assist Dominion from utilities as far away as Oklahoma, Florida and Quebec will begin heading home. Still, Dominion had a workforce Tuesday of more than 11,000 working to restore power.

"We remain committed to having the power back on for virtually every customer by Friday," said Jimmy D. Staton, senior vice president-Operations. "We will maintain a strong workforce in the field while also saying thanks to those crews that must return home. We could not have achieved this restoration effort without them."

As cleanup continues, Dominion continues to ask its customers to work safely around downed power lines, especially those that are intertwined with fallen trees. Dominion is beginning to remove electric line material from customers' roads and yards as well as work with cities and counties as they remove the debris from Hurricane Isabel.

Dominion also expects that most of its customers will receive estimated bills for the present billing cycle. Not only is this as a result of the extreme damage to the system -- in some cases meters and meter bases were ripped off of homes by falling trees and rendered inoperable -- but employees who assist in this monthly task were pressed into restoration activities. Dominion is adjusting estimated bills in an effort to account for the reduced usage caused by Hurricane Isabel outages.
