PSEG spokeswoman Brooke Houston in an email explains there was an equipment failure at the Monument Breaker Station in downtown Trenton around 10:15 a.m. that affected approximately 600 customers in the area of West State Street . "We restored most of these customers about an hour later. We’re working to restore all customers now. The cause of the outage is under investigation."

Several buildings in downtown Trenton including housing the New Jersey Department of Labor and Workforce Development, NJ Environmental Protection and the New Jersey Department of  Environmental Protection were all evacuated.  Statehouse reporter Kevin McArdle reports the power at the Statehouse went out for an instant and came right back.
