Arlington VA Power Outage Today: 4000 Dark as Dominion Responds

Arlington, Virginia — Thousands of Dominion Energy customers in Arlington County were left without power after a sudden outage disrupted electrical service across several neighborhoods and commercial areas. Utility crews are working to restore electricity while investigating the cause of the interruption.

The outage began unexpectedly Tuesday, affecting more than 4,000 customers throughout parts of Arlington. Residents reported lights flickering before service was lost, while Dominion Energy’s monitoring systems detected multiple circuits going offline, prompting an immediate response from field technicians.

The power interruption has affected homes, businesses, and public facilities across the county. Several restaurants, retailers, and other businesses experienced operational disruptions, with some temporarily closing or relying on backup generators to continue serving customers. Schools and public buildings in the affected areas have also been monitoring the situation and implementing contingency plans where necessary.

Traffic conditions were impacted after signals at several intersections lost power. Local authorities reminded motorists to treat any intersection with non-functioning traffic lights as a four-way stop and to exercise additional caution while traveling through affected areas.

Dominion Energy dispatched repair crews to inspect substations, distribution lines, and electrical equipment serving the impacted neighborhoods. According to the utility, preliminary assessments suggest the outage may have been caused by localized equipment failure rather than a widespread issue affecting the regional electrical grid. Crews are working to isolate the damaged equipment and reroute power where possible to restore service safely and efficiently.

Officials have encouraged residents to take several precautions during the outage, including keeping refrigerator and freezer doors closed to help preserve food, unplugging sensitive electronic devices to protect them from possible power surges during restoration, and staying well away from any downed power lines, which should always be considered energized and dangerous.

At this time, Dominion Energy has not announced an estimated time for full restoration. Repair crews remain on site conducting inspections and making necessary repairs while the investigation into the cause of the outage continues.

The Arlington power outage remains an active response as Dominion Energy works to restore service to all affected customers. Residents are encouraged to monitor official Dominion Energy outage updates for the latest restoration information and follow guidance from local emergency management officials until power has been fully restored.
