Dominion Energy Virginia reported burying 2,500 miles of outage-prone power lines statewide since 2014 through its Strategic Underground Program. The company stated burying lines significantly reduces power outages and restoration time, cutting average outage time for affected customers from 11 hours to 2 minutes. Five hundred sixty miles have been buried in Hampton Roads, including 140 in the Williamsburg area, with 4,000 more miles planned. Dominion Energy also highlighted its Mainfeeder Hardening program which replaces older poles and lines to improve reliability.
