Loose American Flag Into Transmission Lines Triggers Major Outage

Connecticut Power Outage after a loose American flag hit transmission lines, Eversource says, disrupting service in Stamford and Greenwich during weekend storms and triggering protective trips as crews worked to safely restore customers.

A loose American flag that blew into an energized transmission structure in Stamford on Saturday night, June 6, 2026, triggered power outages and a follow-on trip during the next day's repair work, according to the utility. The incident disrupted service in parts of Stamford and Greenwich as severe thunderstorms moved across southwestern Connecticut.

Utility representatives said the flag became tangled in conductors near the World Wrestling Entertainment building on Washington Boulevard, initially cutting power to about 5,000 Stamford customers; roughly 3,000 were restored within 20 minutes as operators rerouted supply and field crews mobilized.

On Sunday, June 7, at about 1 p.m., crews working to remove the flag reported that it shifted and made contact with an energized line on a separate circuit mounted on the same structure. That contact triggered a protective trip, interrupting service to more than 20,000 customers in Greenwich. Crews restored one of the affected transmission lines within minutes, beginning staged service restoration. For the regional grid context, related coverage, such as the Louisiana power grid, examines transmission operations and planning considerations in other states.

As of around 2:15 p.m. Sunday, approximately 41,000 of the utility's 1.3 million customers statewide were without power, including roughly 11,500 in Stamford and about 28,000 in Greenwich. Other outages reported around the state were largely attributed to trees and branches falling onto lines during the severe weather, which initially cut service to about 10,000 customers on Saturday night. Large-scale outage reporting that explores severe weather impacts includes New Orleans power failure to provide additional perspective.

The utility noted that the affected structure carries two separate transmission circuits. In conditions like this, crews work to clear foreign material, maintain safe approach distances, and coordinate switching so one circuit can remain in service while the other is isolated. However, unexpected movement of conductive material can momentarily bridge clearances, prompting protective devices to operate as designed.

With additional storms possible and seasonal demand increasing, the episode underscores how nontraditional hazards can propagate through the bulk power system and swiftly affect tens of thousands of customers, even as restoration progresses.
