An underground transformer exploded in downtown Nashville Friday morning, according to the Nashville Fire Department.

Brian Haas, a spokesman for the department, had few details beyond saying the transformer was located at First Avenue and Broadway and that hazmat crews were dispatched.

It was initially unclear when the explosion occurred but Jimmy Holmes, a fire assistant with the department, said it began shortly after 9 a.m.

As of 10:50 a.m. the situation had been contained and only two buildings were without power as a result of the explosion, Holmes said.

Nashville Electric Power was taking the lead and no injuries were reported, he said.
