Dominion Energy finishes burying 2,000 miles of power lines ahead of hurricane season
Dominion Energy Virginia has completed the burial of 2,000 miles of power lines as part of its Strategic Underground Program, launched in 2014 to reduce storm-related outages and speed up restoration. This initiative targets the most outage-prone areas to enhance grid resilience. The company plans to extend the program to bury several thousand additional miles of overhead lines in the coming years. Another resilience effort, the Mainfeeder Hardening program, aims to replace older poles with more robust ones, and has already hardened over 265 miles of power lines since 2019, aiming for 1,000 miles by 2030. The Atlantic hurricane season, starting June 1, is projected to be active. Dominion Energy reminds customers to prepare by reporting outages, avoiding downed lines, charging devices, properly connecting generators, and stocking emergency supplies.

"We launched this program a decade ago after finding that a significant number of storm-related power outages were occurring in a relatively small number of areas," said Ed Baine, President of Dominion Energy Virginia. "By burying the lines in these outage-prone areas, we're not only reducing the number of outages, but we're also shortening how long it takes to get the power back on."
The Strategic Underground Program is one of several programs that the company has launched in recent years to reduce power outages and make the grid more resilient. The company's Mainfeeder Hardening program, for example, is replacing older poles with taller, stronger ones that are rooted deeper in the ground and spaced closer together. The new poles are engineered and built with fiberglass cross-arms, which help prevent fallen trees or limbs from bringing down the entire pole. Since 2019, the company has hardened over 265 miles of power lines, with the ultimate goal of hardening 1,000 miles by 2030.
The Atlantic hurricane season began on June 1 and runs through November 30. This season is expected to be active, so Dominion Energy is reminding customers how they can prepare:
- Know how to report a power outage and track your restoration time.
The Dominion Energy mobile app is the easiest way. Customers may also use the Dominion Energy website or call 866-DOM-HELP. - Stay away from downed power lines.
If you see a downed power line, please report it by calling 866-DOM-HELP and stay at least 30 feet away. The line could be energized and dangerous. - Charge your devices before the storm.
Fully charge your phone, computer and other electronic devices before a storm arrives. Consider purchasing portable batteries to extend the life of your devices. - Properly connect your generator.
If you have a generator, make sure it is fueled, tested, and properly connected before the storm arrives, and always operate it outdoors with good ventilation. - Prepare food, water and emergency supplies.
Before any storm, it's always good to have bottled water and non-perishable food on hand, as well as emergency supplies such as flashlights, batteries, first aid kits and medications.
